Write faster. Catch mistakes. Keep your words private.

Hi, I’m Bartosz, the independent developer behind FluentTyper — a free, open-source browser extension that helps you write with less effort and more confidence.

Whether you’re answering emails, writing in another language, or typing the same replies every day, FluentTyper helps you get your words onto the page — without sending your writing to a cloud service.

Less typing. Autocomplete helps you finish words, while custom text shortcuts turn a few characters into reusable replies, signatures, and snippets.

A second look before you send. Review highlights spelling, grammar, punctuation, and other writing issues. See suggested changes, apply individual fixes, or use “Fix all safe” for eligible corrections.

Optional AI, on your device. Local AI Review adds context-aware English corrections and on-request rewrites. Choose a clearer, friendlier, or more professional tone, then decide what to apply. It runs locally after setup, not on a remote AI server.*

FluentTyper is available for Chrome, Firefox, and Edge, with support for English, Spanish, French, Croatian, Greek, Swedish, Polish, German, Brazilian Portuguese, and Arabic. Feature coverage varies by language and browser.

Help keep independent software moving

I currently pay hundreds of dollars each month for development out of my own pocket, alongside the time I spend building, testing, and maintaining FluentTyper.

Your support helps cover those costs and fund better proofreading, smoother website compatibility, and continued maintenance.

My first goal is simple: make ongoing development financially sustainable.

Does FluentTyper make your day a little easier? Buy a €5 coffee or become a monthly supporter. Every contribution helps share the cost of building useful, privacy-first software.

Thank you for supporting FluentTyper — and the person building it. ☕

Local AI currently supports English on compatible Chrome and Edge setups and requires WebGPU support and an initial multi-gigabyte model download. Firefox uses non-AI Review. Your writing is not uploaded for AI processing.
