I built Mastros because Telegram is full of useful information, but most of it stays trapped inside the chat interface. Communities, channels, support chats, research groups, media, contacts, and long conversations often contain data people need to organize, archive, or analyze. The usual workaround is messy: copy messages manually, take screenshots, save media one file at a time, run scripts, or use tools that feel too technical. I would love your feedback

looks interesting, good utility
It's a good product; please continue to refine it.
A practical tool for Telegram power users. Exporting chats, contacts, members, and media into organized files can save a lot of time and make data much more usable outside Telegram. Nice work!
