Hey Product Hunt,
I built Mastros because Telegram often becomes a place where important information gets trapped.
Communities, channels, support chats, research groups, media, contacts, and long conversations can all contain useful data, but working with that data outside Telegram is still awkward.
The usual workaround is messy:
• copy and paste messages manually
• take screenshots
• use Telegram Desktop exports when available
• run scripts or API tools
• save media one file at a time
• lose context across groups and conversations
Mastros is a Chrome extension that runs inside Telegram Web and turns data you can already access into structured files.
Current features:
• export chat messages
• export group members
• export contacts
• find mutual groups
• download media from conversations
• export CSV, JSON, JSONL, and ZIP files
• browser-based web mode
• optional power mode for larger exports
The product is built around a simple idea: if you can access useful Telegram data in the browser, you should be able to organize, archive, and analyze it without painful manual work.
I am trying to keep the positioning clear and responsible. This is not meant to be a spam tool. It is for researchers, community managers, analysts, operators, and people who need to archive or structure Telegram data they already have access to.
I would love feedback on it
