The Story

The story behind TypoGuard is personal.

I come from a generation that loves to type. We grew up with MS-DOS, Windows 95, MS Word, MSN Messenger, Yahoo Messenger, and ICQ—the tools that shaped how we communicated in the early internet age. For us, typing was never just a method of input. It was how we expressed ourselves, worked, and connected with others.

That has never changed for me.

I never liked the idea of using text-to-speech while everyone around me could hear my thoughts. I did not want to speak to a camera just to send a message. I simply wanted to type—quietly, naturally, and in my own way.

But over the years, I started noticing something frustrating. As we get older, many of us read fewer physical books, write less by hand, and slowly become less confident about spelling. In my case, grammar was never my strongest skill, even back in school. So spelling mistakes gradually became something I had to deal with every day.

For a long time, it was not a major problem because I used Microsoft Word, which had reliable spell-checking, even for languages like Greek. Later, when I started using Gmail every day, I found that its spell-checking—especially in the beginning—was not good enough for me. My solution was simple: I would write my emails in Word first, correct them there, and then paste them into Gmail.

As browsers improved, built-in spell-checking became more common. Chrome and Gmail introduced spelling tools in English and later in other languages, including Greek. Still, I often felt that these tools were not accurate enough, especially when it came to understanding the full sentence rather than just individual words.

Then I discovered something that worked surprisingly well: Google Search.

Whenever I pasted a sentence into Google with a spelling mistake, it often suggested the correct version using the familiar “Did you mean” feature. It was quick, effective, and especially helpful for me in English, which is not my first language.

At the same time, I was writing more and more across different platforms—Airbnb messaging, Booking extranet messaging, WordPress dashboards, Facebook Messenger, Google Messages, Reddit, and many others. Many of these platforms had little or no reliable spell-checking. So whenever I was unsure about a word, I would type it into Google, check the “Did you mean” suggestion, correct it, and then paste it back where I needed it.

Eventually, I had one simple thought:

What if that correction experience could exist directly inside every text box where I type?

That was the beginning of Typo Guard.

With the help of modern AI development tools, I built a Google Chrome extension that does exactly that. It detects spelling mistakes, underlines them in red, and suggests corrections through a tooltip—bringing a more helpful spelling experience directly into the places where we write every day.

Typo Guard began as a solution for my own frustration, but I realized I was probably not the only one facing this problem. Many people still prefer typing. Many people still want to communicate clearly. And many people could benefit from a tool like this.

That is why I created Typo Guard.

I hope you find it useful too.
