Grammarly: How AI Attracts 3+ Crore Users Daily

Grammarly leveraged AI to drive success - here's how!

I mean 3 crore users every day is no joke 🤯! I’ve always used Grammarly and never realized how dependent I was on it! If rarely the extension didn't work for some reason, I would realize just how silly a writer I am 😭. I’d make typos in literally every 3-4 words - I know I am too bad!

Honestly, it’s been a life savior for me because I write a lot. If you’ve been to my LinkedIn, I have been a writer my whole life - and still am. Even here as a PM, I write for you guys! So yeah, now you know why I can’t stress enough how important it is to me.

*Start with the case study already 😑*

Grammarly has transcended its origins as a simple grammar checker to become a cornerstone of the modern communication landscape.

This case study delves into the innovative elements that fueled its rise, analyzing the impact of AI, user-centric design, and strategic partnerships.

Grammarly’s Founding Tale

The Plagiarism Problem

The story begins in 2000, at the International Christian University in Ukraine. Alex Shevchenko and Max Lytvyn, computer science students, noticed a worrying trend: rampant plagiarism among their peers. This sparked a conversation - why were students resorting to stolen content? Was it a lack of confidence in their own writing? Was it the difficulty of navigating the complexities of the English language?

Determined to address this issue, Alex and Max created "My Dropbox," (Same name, eh? Good.) a tool that detected plagiarism in student essays. While successful, they realized the problem went deeper. People of all ages and backgrounds struggled with effective communication, not just plagiarism.

From Education to Everyday Communication

In 2009, with Dmytro Lider joining the team, they launched Grammarly. Initially targeting students, it offered basic grammar and spelling checks. But they envisioned more. They saw Grammarly as a tool to empower everyone, regardless of their background or expertise, to communicate clearly and confidently.

And the rest, as they say, is history! Okay, but we’re gonna grab some of that history and put it here for you - the AI leveraging part!

Fun Fact ⚡️ 

The name "Grammarly" was almost "Correctly." (Thankfully, they saw the light!)

How Grammarly Leveraged AI for Its Success?

1. Beyond Red Underlines: Understanding the Nuances of Communication

Grammarly's AI doesn't just point out typos and grammatical errors; it delves deeper, analyzing your writing's context, intent, and target audience. This allows it to offer more nuanced and valuable feedback than a simple grammar checker.

This is how the AI behind Grammarly works:

  • Contextual Awareness: 

    Grammarly considers the type of writing you're doing, whether it's a formal business email, a casual social media post, or a creative blog article. This context helps it tailor its suggestions to match the specific requirements of each situation.

  • Intent Recognition: 

    The AI tries to understand the message you're trying to convey and suggests improvements that enhance its clarity and impact. It might suggest rephrasing sentences to be more persuasive, using stronger verbs to convey emotions, or adjusting the tone to be more appropriate for the audience.

  • Audience Understanding: 

    Grammarly considers who you're writing for, whether it's a colleague, a potential client, or a general audience. This helps it suggest language and style choices that resonate with your target audience.

The Impact: User Satisfaction and Retention

This shift from "grammar police" to "communication coach" has a significant impact on user experience:

  • Increased satisfaction: Users feel empowered to improve their communication skills and craft impactful messages, leading to a more positive experience with Grammarly.
