Hey Product Hunt ð
I built Quill because every AI writing tool I tried had the same catch: to fix a sentence, you had to send it to someone else's server.
Chrome quietly shipped a built-in on-device AI model (Gemini Nano) that most people don't know is sitting in their browser already. Quill is a thin, focused layer on top of it â select any text on any page (or paste it into the side panel for places like Google Docs), and instantly:
ð Rewrite the tone â 23 styles, from Friendly to Executive to Persuasive
â Proofread grammar & clarity
ð Summarize or pull key points
ð Turn messy notes into a list or table
âïļ Compose freeform with a quick instruction
Nothing you write ever leaves your device. No account, no server, no tracking â it physically can't leak your drafts because there's no cloud round-trip to intercept.
It's free for the 3 core tones (Friendly/Professional/Concise, unlimited) plus 5 free uses/hour on the utility tools. Pro ($3.99/mo, $24/yr, or $39 lifetime) unlocks all 23 tones + custom tones + unlimited usage.
One catch: it needs Chrome 138+ and a couple of flags flipped on (Quill's settings walk you through it in one click each) since Chrome's on-device AI is still an early-access feature. Would love feedback, especially from anyone testing it on Windows/Mac/Linux â device support varies right now.
Thanks for checking it out! ðŠķ

honestly the on-device thing is a nice touch, didn't expect that from a free extension. tried it on a couple of emails and the tone rewrite was actually pretty solid, not the usual clunky ai output.

Really glad to hear that @sebahat55743037Â , especially on the tone quality â that was the part I was most nervous about shipping. Gemini Nano is a lot smaller than what most people are used to (GPT-4-class stuff), so I spent a good chunk of time on the tone prompts specifically to avoid the "obviously AI" flattening you get from a lot of rewrite tools.
Good to know it's landing on real emails and not just my own test cases. And yeah, the on-device thing genuinely was the whole reason I built it this way rather than just wrapping an API â free tools that ship your drafts to a server for processing always felt like the wrong trade for something as personal as email. No downside for you either: same privacy whether you're on the free tier or Pro.
If you keep using it, I'd love to know if the quality holds up on longer/more complex emails too, or if it's mainly strong on the shorter stuff â trying to figure out where the model's real ceiling is.
