About LangsAny
Translation that stays with you.
LangsAny exists because of one conviction: you shouldn't have to hand your words to a server to get them translated. So we moved the translator itself — open-source AI models, running in your browser, on your device.
Every mainstream translation site computes in the cloud: your text is uploaded, processed in a data center, and returned. That design forces three compromises — your content leaves your control, every request costs the provider money (so you get limits), and no connection means no translation.
LangsAny inverts it. A compact neural translation model is downloaded to your browser once, cached, and runs locally from then on. Private, free, unlimited, and offline-capable are not four features we added — they are four consequences of a single architectural decision about where the computation lives.
Translation runs in your browser. Your text never reaches a server — not because we promise, but because no upload path exists.
Your device does the computing, so we have no per-request costs. No character caps, no quotas, no account.
Models are cached on your device. Once prepared, translation works with no internet connection at all.
Where we are today
The translator supports 26 languagesfully on-device (with Chrome's built-in translation AI extending coverage further), streams results sentence by sentence, detects the source language locally, and keeps working offline once a language pair is cached. Everything is free and unlimited — supported by ads, never by your data. We also make LinearCN, a Chrome extension that localizes Linear.app into Chinese.
Where we're going
The same local-first architecture extends far beyond text. In rough order:
200 languages with NLLB-200
In progressA single on-device fallback model (Meta AI’s "No Language Left Behind") covering 200 languages — from Swahili to Tamil to Icelandic.
Document translation: PDF, TXT, SRT, Markdown
PlannedParse and translate whole files locally — subtitles keep their timestamps, documents keep their structure. Nothing is uploaded.
Image translation (on-device OCR)
PlannedPoint at a screenshot, a menu photo, or a scanned page: text is recognized and translated entirely on your device.
Installable app (PWA)
PlannedThe site already works offline after one visit. Next: add-to-home-screen install and an explicit "download for offline" language pack manager.
Local text-to-speech
ExploringHear translations spoken aloud with a neural voice that runs in your browser — no cloud TTS API.
Local speech-to-text
ExploringTranscribe and translate audio on-device with Whisper-class models, for interviews, lectures, and voice notes.
One promise holds for every item above: it ships on-device or it doesn't ship. We will never quietly route your documents, images, or audio through a cloud API.
