Perebot

@perebot bills itself as one of the largest educational translator bots on Telegram, and its monthly-user count (tens of thousands) backs that up. At its core it is a straightforward text translator across roughly two dozen languages, but two extras set it apart from a plain "type text, get translation" bot: it can read and translate text baked into a photo (a menu, a sign, a screenshot), and it turns vocabulary you've translated into short quiz-style drills so words actually stick rather than being forgotten the moment you close the chat.

The bot is maintained by the small studio behind @botfactory, which handles support requests directly through Telegram rather than a ticketing system — a plus for quick fixes, though it also means there is no public roadmap or changelog to check freshness against. There is no sign-up flow: you open the chat, send text or a photo, and get a translation back.

Because it leans on general-purpose translation and OCR rather than a dedicated linguistic engine, don't expect the nuance of a professional service on idiom-heavy or highly technical text — it is built for everyday phrases, travel situations, and vocabulary building, not literary translation. For that everyday use case, and especially for the photo-translation trick, it earns its place among the more capable free options.
