AI-powered spell correction for your favorite chat platforms

TypoGuard – AI-Powered Text Correction for the Web TypoGuard is a Chrome extension that automatically detects and corrects typos and grammar mistakes as you type — inspired by Google's familiar "Did you mean?" experience. Whether you're writing a message, drafting an email, or chatting with an AI assistant, TypoGuard works silently in the background and with a mouse over suggests corrections before you hit send. It is compatible with popular web platforms, including messaging apps and chats.

I'm Dinos, the maker of TypoGuard — and I wanted to share the story behind why I built this.
It started with an embarrassing moment. I sent a message to a client through Facebook Messenger with three typos in the first two sentences. The message had been "corrected" by my phone's autocorrect into something that didn't even make sense. I remember thinking: we have AI that can write entire essays, but I still can't get a simple spell check inside a chat window?
That frustration turned into TypoGuard.
The core idea is simple: your browser should silently fix your typos where you actually type — not in a document editor, but in ChatGPT, Gmail, Claude, Messenger, Airbnb messages, and everywhere else you communicate online. Inspired by Google's "Did you mean…", it suggests corrections before you hit send, powered by Gemini AI.
A few things I'm particularly proud of: → Zero friction install — no account, no API key, no credit card. One click and it works. → It covers platforms that no other tool touches (Booking Extranet for hotel managers, anyone?) → The free plan is genuinely useful — 50 corrections/month with no strings attached.
🎁 Exclusive for the Product Hunt community: Use code PHUNT50 for 50% off Premium for the first 3 months. Valid for 14 days only.
I'd love your honest feedback on: → Which platform should we support next? → Is $6.99/month fair for unlimited corrections + multilingual support? → What would make you switch from Grammarly?
This is day one. Your feedback today will directly shape what we build next. Thank you for being here. 🙏
