Flueno

@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.

Everything is currently free: the developer, Ilmar Mansuroff, states all functions are free during what's explicitly called a testing phase, with support available directly through Telegram if something goes wrong or you have questions. That framing is also the main thing to keep in mind going in — "testing phase, free for now" is a normal way indie AI products validate demand before introducing pricing, so don't assume the current free access is permanent, and expect the feature set (and possibly the price) to keep changing as the project matures.
