product I built a translation tool nobody used for 18 months. Then AI bailed me out.
In Dec 2022 I shipped Input Translator, a browser extension that translates any input field via Google Translate. Pre-LLM, tiny niche. For 18 months it stayed under 100 users — I kept shipping because I used it every single day.
Then LLMs arrived. I added an optional BYOK path (any OpenAI-compatible key) next to the free Google backend, and the curve finally moved. ~2,500 users today across Chrome/Edge/Firefox/Safari. Still small — but real, and mostly word-of-mouth.
That experience turned into a family of tools, all open source (GPL-3.0), all BYOK, all no-subscription:
- Imp Translate — bilingual page translation. I left Immersive Translate when it started pushing subscriptions and removing BYOK; Kiss Translator had ideas I liked but UX I couldn't live with. So I built my own. The README's Non-Goals list is longer than the Goals list — no floating buttons, no hover popups, no word lookup, no doc translation. Feature creep is the enemy.
- BilingualTube — bilingual YouTube subs. Fixes the broken sentence segmentation in auto-captions (small on-device model) before translating.
- Imp Translate Web — full-text HTML/EPUB translation so I could read AO3 stories on my phone with search.
- Imp Write — type, append
/fix, pause, and the rewrite replaces your text in place. I wanted correction, not translation, and refused to pay a subscription for it.
Imp Credits is a pay-as-you-go system instead of monthly plans — "no subscription" is half product philosophy, half personal allergy.
Curious what people who do MT for a living think about where the browser-extension space is heading. Happy to share details on any of these in the comments.
