An AI conversation-practice bot for English, German, Serbian and French: it sends audio and text, you answer by voice or text and get corrections and tips. A one-person project that was free during testing; current pricing is not published.
@langpractics_bot, branded Flueno, is an AI conversation-practice tool covering four languages — English, German, Serbian and French — inside a single Telegram bot. It works by sending you audio and text messages meant to imitate a real exchange with another person, and you can reply either by voice or by typing; the bot then analyzes your response and suggests improvements, aiming to simulate practicing in a variety of everyday situations rather than a fixed script.
The pitch is aimed at people who want practice on their own schedule — described as useful for busy people, students and travelers who can't commit to a fixed lesson time but want to keep a language active. Having Serbian alongside the more commonly covered English, German and French is unusual among Telegram language bots and worth noting if that's the language you're after.
Pricing is the open question. When the author, Ilmar Mansurov, listed the bot on Product Radar in July 2024 (then as Lang Practice, with Spanish among its languages), every feature was free during a testing phase. Since then the bot has been renamed Flueno, Spanish has disappeared from its description, and no current price or plan is published anywhere, so check inside the bot before you rely on it. Early reviewers on Product Radar noted that it adapts to the speaker, corrects mistakes, lets you play a phrase back to hear the pronunciation, and reads Serbian in both Cyrillic and Latin script. Questions go straight to the author on Telegram, whose profile calls Flueno his pet project.
