GemType

A note from the maker· riponcm

Hi OSSDROP — I'm Ripon, a solo founder at Matily, an open-source studio. I wanted Grammarly's "fix my writing everywhere" experience without the subscription, the account, or my text going to a company's servers. So I built GemType. GemType underlines grammar and spelling mistakes in any text field — Gmail, LinkedIn, X, Reddit, docs, forms — and fixes them in one click. Select any text and you can rewrite it too: Improve, Shorten, Formal, or Casual. And it works in any language, automatically. It's live today on Chrome, Edge, and Firefox. The twist: it runs on YOUR own free Google Gemini API key. That means: - It's genuinely free (Gemini's free tier is plenty for daily writing) - Your text goes straight from your browser to Google's API — no GemType server in the middle, no account, no tracking - It's fully open source (Apache 2.0), so you can read and audit exactly what it does Where it's going: GemType isn't just a browser extension — I'm building it to follow you everywhere you write. iOS and Android keyboards and a Microsoft Office add-in are next, all sharing the same private, bring-your-own-key core. A few honest notes: - You need a free Gemini key from Google AI Studio (2 clicks, no credit card). It's one extra step vs. Grammarly — the price of "no middleman server." - Google Docs isn't supported yet (it renders to a canvas and locks its API to whitelisted vendors). - It's an indie/solo project. A Safari build is ready too — I just need to cover Apple's $99/yr developer fee, so I set up GitHub Sponsors. I'd genuinely love your feedback — which platform should I ship next, and what would make you switch from Grammarly? I'll be here all day. — Ripon, founder of Matily P.S. GemType isn't affiliated with or endorsed by Grammarly — I just wanted an open, private take on the idea. "Grammarly" is a trademark of Grammarly, Inc.
