Episode Show Notes
On this episode of The Marketing Growth Podcast, host Shane Barker sits down with Lisa Lepki to dive into ProWritingAid’s phenomenal growth story. In just five years, ProWritingAid has soared from zero to 1.5 million users by harnessing a unique blend of advanced algorithms and a writer-first approach. Lisa shares how the journey began with a chance encounter on a bus in Vietnam and a broken ankle that sparked the creation of an editing tool designed to improve writing quality.
She explains how the platform leverages the expertise of computational linguists to compare amateur writing with published works—spotting issues such as overuse of passive voice and repetitive phrases. By offering a comprehensive free version, ProWritingAid not only empowers users to improve their content through in-depth analysis and interactive tutorials but also builds a community of advocates who spread the word. The conversation also highlights the company’s agile approach to inbound marketing, utilizing webinars, blog posts, and integrations (like add-ins for Word, Google Docs, Chrome, and Firefox) to continually enhance user experience. Lisa’s insights demonstrate that dedication to quality and accessibility can drive explosive growth while keeping prices reasonable and the community at the center of innovation.

Welcome to the Marketing Growth podcast. This podcast episode is sponsored by Ahrefs. I’m your host, Shane Barker. In this episode, Lisa Lepki is back with us to discuss ProWritingAid. Phenomenal growth story—in five years, they’ve gone from zero to 1.5 million users. I have a lot of questions about the revolution, but let’s start with how Lisa got started with ProWritingAid.
Before we get started, I wanted you guys to know that Ahrefs is offering a great deal right now. You can get a seven-day trial of the software for just $7. The best part is they’ve recently opened up two of their tools—Site Audit and Site Explorer—for absolutely free. For content marketing and SEO, it’s one of the best tools out there. For sure. Don’t forget to sign up for this offer.
So how did the writing thing—how did that translate into working for ProWritingAid? What was the transition there?

Lisa Lepki
Yeah. So for for about eight years, I was working doing PR for an arts PR agency. So I worked with English National Ballet and Blue Mind group and all kinds of really big theater and dance and comedy companies. And I had just finished a big project when my friend Chris told me that he had just started this little software company, and I would help him a little bit with some of the early marketing messages and to build the first website and that sort of thing. He’s an old friend of mine. We met on a bus in Vietnam about in about 2001 or something like that. And he’s, he’s done a million different jobs. He’s one of those guys that is really imaginative and creative, and was in the middle of writing this book. But then he also has that sort of coding mind as well. And so he is this bridge between these two kinds of brains that that is kind of magical.
And so just to keep him, so then he was, he was doing a job, and broke his ankle and ended up having to stay in bed for ages, and so to keep himself busy, instead of just watching crap TV like the rest of us would, he just invented a little algorithm and some software to help him edit his own book and then put it online, and people started using it, and then became completely obsessed with all the different ways that computers can help writers find issues in their writing. Five years later…

It’s insane. Yeah, we’re going to talk about how many writers you guys have on the platform. It’s insane. I love how you explain it. You’re like, oh, he just uses both sides of his brain, and then he hurt his ankle, and then boom—he started a little software company with an algorithm. You make it sound like you just put two plus six and it equals eight, and then, oh, here’s a company! Like, shout out to the writers on my team. Shout out to anybody that does coding.
I took a coding class five or six years ago—not to be a coder but to get a better idea. And the instructor, I felt bad for him. He’s like, I don’t know how you got into this class. This was after college, and I just remember looking at it… My brain with coding? It just doesn’t work. I’m ADHD—like, oh look, squirrel, shiny penny. And he’s like, no, you’ve got to focus. And just the way coders work is insane. I’ll walk by a coworking space and someone’s got this giant screen and it looks like they’re talking to the Matrix or Neo or something. It’s just absolutely incredible.

Lisa Lepki
Yeah, and I don’t even think he’s ever really taken a coding course. He just wanted to figure it out and taught himself. He can get super zeroed in and just figure anything out. Our whole company is really DIY. If you want something done, you figure out how to do it. If you want a blog for the company, you figure out how to build it and design it. We don’t really hire agencies. Everyone just figures it out.

Just goes for it. That’s awesome. So tell us a little bit about ProWritingAid. You’ve kind of touched on it a bit. Tell us exactly how the platform works—what’s the fun stuff?

Lisa Lepki
Okay, so we have this amazing team of computational linguists. What those are is—they’re experts in the English language. It’s their job to figure out how language works and how every word works together. Then they use what they’ve learned to look at published writing compared to amateur writing. They look for the differences and common stats, and then they use that info from thousands of books to find things in your writing that are different from published work.
So, for example, in successful, traditionally published writing, people use passive voice in fewer than 50 out of 1,000 sentences. And just for anyone listening—passive voice is like, instead of saying “John threw the ball,” you say, “The ball was thrown by John.” It’s the same words, just different order. That’s easy for a computer to pick up and measure. So if you’ve written something and our software finds that you’re using it 200 times out of 1,000, for example, it flags that for you. It’ll say, “You’re probably doing this too much.” And then it shows you the sentences that are problematic so you can rewrite them to be more engaging. Readers can just absorb active voice better than passive.
Take that example and multiply it by 1,000. Our software has literally thousands of rules and suggestions. It’s like having a copy editor tap you on the shoulder saying, “Hey, how about this?” Maybe this sentence is overly complicated. Maybe you’ve used an adverb where a stronger verb would work better.
And we also include teaching around it—so if you get flagged for passive voice, there’s a video explaining why it matters, or a blog post to help you improve. The ultimate goal is to help you become a better writer while you’re editing your own work.

That’s awesome. I mean, that’s once again. I wish we would have met, wish the software was here about 25 years ago when I was jumping in this room and to go, “Hey Shane, don’t do that again. Please don’t do that.” Oh yeah, sounds good. Thank you so much for keep telling me over and over and over, and one day I will listen, I promise.
So you guys—and I know you guys kind of tote and kind of talk about being more like user focused and feature focused—kind of talk about that a little bit, because it sounds like you guys are very like, I mean, it sounds like it’s very intuitive, but it’s also kind of like you got to kind of get in there and start using it, right? I mean, it’s more user focused, kind of getting that feedback.

Lisa Lepki
Yeah, definitely. I mean, we—because we’re all writers at heart—we’ve built everything around what we think would be useful for us as writers.
And so in your basic spelling and grammar checker, it just tells you, “You should fix this,” and you don’t get any of the understanding behind it, and you’re not really building your skills, you’re just finding mistakes. And a lot of the other grammar checkers in our sort of vertical are the same, whereas we really want to help all of our writers become the best writers that they can be.
And so whether they’re students and they’re trying to write good essays, then we try and include lots of content beyond just the copy editing side of things that our app does. But we also have a blog that has tons of information about how to write a good essay, or how to write really good content, or how to use it as a teacher, or how to use it at work, and that sort of side of things.
So we really try—and our biggest focus in marketing has been inbound marketing. We just try and create all of the things that we think would be useful for writers. And we just thought, if we build it, they will come. And they’ve come, for sure.

We’re going to talk about that. I mean, it’s kind of silly to me. It’s like—I love it because it’s, “Hey, it’s not just hey, you made this mistake. You shouldn’t do that.” It explains why you shouldn’t do that. And so you can make those changes moving forward.
Like it really is like, “Hey, we’re here to get you to a better point when it comes to your writing skills,” right? And educate you—not just see—so you understand the premise of why that’s wrong and the reason why you should change it and why you should do more of this?

Lisa Lepki
Yeah, exactly. I mean, eventually writers shouldn’t even need us. That would be great.

I know. How does that work out? Like, when do you graduate? When the thing’s like, “Listen, we have nothing else to tell you. You just wrote this book and it’s super solid. We’re gonna let you go now. You’re off on your own.”

Lisa Lepki
Yeah, no, that never happens. I mean, even though I know all of these rules off by heart—and I’ve talked, you know, for hours and hours and hours of my life about the importance of not using adverbs, for example—I’ll still write something, and when I go back and read my first draft, I’ll have made all of the same mistakes in it.
But then it highlights it, and then I can fix them, right? As opposed to having to go through them and starting from scratch.

Yeah. I mean, that’s the cool part. I would—well, I mean, I’ll be honest, I haven’t used the platform. Actually, well, we did—I did go in and take a look at it with a review. But I’ll tell you, the functionality of it, I guess what I’m saying is I need to use it more. I guess as I’m saying that, I need that. I need you in my life. I need your platform in my life, because I need to be a better writer. I do.
As we touched on earlier, next time we talk, I will be a better writer. How about that?

Lisa Lepki
Everybody needs to be a better writer. Even if you don’t want to be a writer, you still—you know, everybody that’s at work is writing emails all day and writing reports and doing, I don’t know, all kinds of things. Almost every part of work now involves some sort of writing. So the more you can improve your communication skills—even if it’s just to write email—then great. That just makes you sound smarter.

Yeah, it really—and it’s so crazy because once again, as I was talking about Miss Schwartz, my teacher from a long time ago, my English teacher—I mean, you didn’t realize how much it was going to be a part of anything we do. I mean, everything we do, right? Emails and everything.
It’s like, all of a sudden, it became this focal point. I mean, we write content. I see you guys write content as well. And so we write for so many different websites. And I never, ever imagined that it would be that way. That I would do something that would be like inbound marketing, where we would go and do those types of things. So it’s kind of interesting. It’s kind of crazy.

Lisa Lepki
It didn’t exist back then, did it? It’s a whole new world.

Yeah, it is. Man, who knew? Jesus, I would have been a little more prepared. I think we’ve already gone over that. So how are you guys—and you touched on this a little bit—than some of the other writing platforms that are out there. How are you guys different?
I mean, it sounds like you guys are just intuitive. It sounds like you say what the problem is, and this is what the solution is, and then you explain why that is. Is that the main differentiator?

Lisa Lepki
Yeah, I think the main—the thing that makes us really different is that we really focus on learning, and it’s something that we’re trying to do even more of.
We now—as of about eight months ago—we now have videos and full courses right on the platform itself. So if you get a suggestion, then there’s a video of me or Chris or somebody else actually explaining it there. Yes, we’re really trying to build out that learning side of things.
But we’re also a really—we’re still a pretty small, nimble company. You know, as I was saying, we do everything ourselves. And so if opportunities come up, we can sort of jump on it, and we can really talk to other people in the writing community. Because the writing community online is—it’s huge. Writers love talking about writing, and they love writing about writing, and they love reading about writing, and they love building their skills.
And so I think the fact that we are all writers has just made that easier, as opposed to, you know, some of the bigger companies that have, you know, millions in investment. And they have to—you know, they have a lot more boxes to tick, whereas we can be pretty nimble and we can jump on pretty cool opportunities.

Which is—I think it’s huge, because you know, the problem is, when you get millions of dollars, once again, those boxes that you have to check don’t always have to do with the core of what your business is, right?
And so it really—it becomes a difficult thing, and then you have to—it becomes users and numbers and stuff, and you’re maybe not quite as invested in the actual community as you are in getting to certain points, and whatever that is—software, anything like that.
So—and you guys have recently—I think just, well, pretty recently—you guys are at what, a million users? Or even over that, aren’t you guys…

Lisa Lepki
We’re at a million and a half now!

See what happens in this last week. Things have—we got updates here, folks. 1.5 million users? That is silly. Yeah. So how did—I mean, and you’ve only—you’ve been with the company for what, how many years now? 2015? Five years?
Okay, so then walk me through that. Like you’re talking a million users—I mean, 1.5—you. I mean, we talk about that like it’s nothing. Like, oh, you just went picked up a few people, and you had a few signs, and people signed up. Like, that’s crazy. Like 1.5 million users is, like, silly.

Lisa Lepki
Yeah. I mean, I think part of the reason we’ve grown so much is that we have a really comprehensive free version of the software. And so a lot of those users are just free. And unlike some freemium versions of products that are all full of advertising and lock away all the best features—we don’t do any.
We had a bit of advertising in the beginning, and then we decided it didn’t really fit with our ethos. And so now we just—the only difference between free and a paid account is the free users are limited to 500 words at a time.
So if you’re just writing emails and that sort of thing, that’s fine. But if you’re writing anything that’s a bit more in depth, then it’s good to be able to look at your statistics over your full document or full report or full blog article—just to, because you can check for things like repetitiveness. If you’ve used the same phrase five times in your blog article—because readers clock that sort of thing.
So if you can look at it on a bigger picture, that makes a difference if you’re properly trying to do some good content.
And then the other thing that paid users can use is all of our add-ins. So we’ve got add-ins for Word and for Google Docs and for Chrome and Firefox and all the rest of them. But a lot of our growth has just been due to the fact that we have something really cool that people can use for free, and then they learn to love it, and they tell their friends.
And I mean, so much of it has just been our users championing us to other writers that they know.

It doesn’t get any better than that. Like when you have a great tool that you offer for free—and obviously some people just keep the free version—obviously if you’re serious about it, you want to upgrade to the pro.
But just having other people—that actual natural growth of, I think, truly caring, right?
Because I’ve been on plenty of free platforms where it’s like, they—you’re right underneath the level of being able to be productive on a free software, you know? Like I almost got something done, and I almost was cool for a second, but then it was…
And it’s not the 20 or 50 bucks that I’m not willing to pay. It’s like, I kind of want to test it out a little bit. And it kind of sounds like you guys really cared about developing something that somebody could use for free.
I mean, 500 words—which is plenty if you’re doing emails or whatever that is. But for the person that says, “Hey, listen, I just need to go up to that next level.” Even the price point for you guys isn’t that high, right? I mean, your software is not expensive from what…

Lisa Lepki
Yeah, and we’ve really tried to—I mean, it’s a bit strange because we’re one of the least expensive softwares out there, but we’ve got the most features.
And we keep having this conversation about, like, should we increase our prices so that we’re in line with everyone else? Because if we’re the least expensive, will people then think that we have the lowest value, right?
But we don’t actually want to price ourselves out of accessibility for too many people. Like, we want this to be free. We want to be able to help as many writers as possible. And we want to make it accessible to as many people as we can.
And so yeah, we’re just—we’re just trying to keep the prices reasonable so that we can have as many people as possible.

Well, I will tell you, we appreciate you keeping them reasonable. Because that’s what—that’s what I like to pay—is reasonable prices. It’s right in that little category.
Hot area for me is reasonable. Reasonable, reasonable. That’s a good question. Just reasonable. I just want to keep it right in that area. Why not?
So what would—is there any other apps that you can think of—I’m just talking about for, like, other aspiring writers and stuff. I mean, with ProWritingAid, obviously you guys have done an amazing job.
Is there any other tools that you use as a writer? I’m just trying to think of outside of what you guys have created. I don’t know if you need anything else, to be honest, but is there anything else?

Lisa Lepki
I mean, there’s lots of tools that we use to run our team. We do all of our planning and editorial calendars on Trello. I just think Trello is a magical thing for trying to keep yourself organized in any sort of way.
We do all of our collaborative documents on Google Docs—which, you know, they’ve got some limitations—but if you’ve got lots of people going in and out, you don’t have the issue of multiple versions and things getting lost or anything. You’ve just got a link, and everybody works in the same one.
Tons of our users use Scrivener, which I personally don’t use, but we hear about it all the time—for people that are doing big projects, or even people that are running a lot of content. I think once you get your head around it—it’s quite a bit of a learning curve—but once you get your head around it, I think it’s really useful. And so we have an add-in for that as well.
But yeah, I mean, when it comes to writing, I think the most important thing is just a good writing platform that you feel comfortable in, and that makes sense for you—and then just to sit down and get the words out.

Get it done. So with the pro version, the benefit to that too is that, if you’re using it on Google Drive or anything like that, it obviously will make suggestions as you’re going, so the whole team can have accessibility, which is awesome.

Lisa Lepki
Yeah, exactly. And you can—we’ve got a Chrome extension so you can use it on almost any website. You can use it on Gmail, on all of those sorts of things, just to try and catch your errors before you push send.

That’s a beautiful thing. That is a beautiful thing. Like I said, I wish you guys were around—or I should’ve known about you—a few years ago, because there were a few emails that I was like, okay, I don’t know… no wonder they didn’t respond. Because they’re like, “Okay, he’s been hacked obviously, and somebody else is writing something for him.”
So that’s good, that’s good. So what is the plan for ProWritingAid? I mean like, globally—you guys have 1.5 million users, which is… I mean, just to wrap my head around that is absolutely insane. And it sounds like your users are your main advocates, which—like—it doesn’t get any better than that.
Do you have anything you can tell us about? Like, is your plan to get to 3 million, 5 million? Do you want to go global? Are you starting to look at other languages like Spanish? What’s—can you give me anything?

Lisa Lepki
Yeah, so initially we were talking about doing Spanish. We have a fairly unimpressive version in Spanish, but I think there’s probably a lot more that we can do in English before we start moving into other languages.
I just say that because people ask us all the time if we have German, and French, and Spanish, but I think there’s still a lot more that we can do in English and in our platform, and we still have all these different ideas that we want to do.
So in a lot of ways, I think we’ll probably just keep doing what we do. About half of our users are in the States and the other half are in other English-speaking countries around the world—you know, Australia, UK, Canada, Ireland. That’s probably the other half.
But we’ll probably just try and do more of what we’ve been doing, which is mostly inbound—creating really good content.
We just started, since March, doing a series of webinars—just free webinars. We just reached out to all these experts in our field and asked them if they would do some free training for us, and it’s actually worked really well for us.
So it’s given a lot of value to our existing users, but then it’s worked as a lead generation for lots of new users across social who come in and discover us because they want to learn how to query their manuscript, for example—might be a topic.
And then we’ll have another article around that, and so it all sort of feeds in together. And you know, it’s like I was saying—doing content that writers are looking for, and that adds some value and helps us build our profile and a bit of authority as experts in that field.

Yeah, that’s awesome. We kind of did the same thing when I started the blog, I think, eight or nine years ago—I don’t know what year it is, but whatever—a little while ago when we started doing it, all of our stuff is inbound too.
It does take a while to do, but once you start producing great content and then people start inquiring—like yours obviously is very writer-based, like “How do I do this?” or, you know, “How…” You look at certain keywords.
It’s the same thing for us—for SEO or influencer marketing or content marketing or whatever that is. It’s like, what are the queries that people are putting in? And can we be the answer to that?
That inbound has been absolutely amazing. I mean, I always say this on my podcast—I don’t have a huge sales team that’s out there outreaching people. Everybody that inquires, they inquire with us about help that they need.
It’s been interesting because we made that early investment. And of course, the reason we invested is because I thought it was going to pay off—and it absolutely has.
And I think the key is, writing is getting out there and putting out great content that people love and enjoy. And great, if you have a SaaS product—especially a great free SaaS product—and then you get in and start writing.
And writing obviously is a part of what we do every single day, and why not upgrade to the pro? So I think that makes total sense.

Thanks, Lisa. It’s been a pleasure getting to know more about what’s going on behind the scenes at ProWritingAid. We’re short on time, so let’s wrap up this segment right here.
Stay tuned—I’ll be back next week with more questions for Lisa.
