Mastros - Telegram Scraper

Mastros is a Telegram Web export Chrome extension for turning Telegram conversations, groups, contacts, and media into structured files.

Export data from Telegram Web directly from your browser. Save chat messages, group members, contacts, mutual groups, photos, videos, voice notes, documents, and other media from conversations you can already access.

Mastros helps you move Telegram data out of the chat interface and into clean files you can organize, archive, analyze, or reuse.

What you can do with Mastros:

• Export Telegram chat messages
• Export Telegram group members
• Export Telegram contacts
• Find mutual groups
• Download Telegram media
• Save photos, videos, voice notes, and documents
• Export CSV, JSON, JSONL, and ZIP files
• Use browser-based Web Mode for simple exports
• Use optional Power Mode for larger workflows

Mastros is useful for researchers, community managers, analysts, operators, content teams, support teams, and anyone who needs to organize Telegram data outside the app.

Use it for:

• Telegram data export
• Telegram chat archiving
• Community analysis
• Research workflows
• Media backup
• Group member exports
• Message exports
• Contact organization
• Structured CSV and JSON exports

Instead of copying messages manually, taking screenshots, saving media one file at a time, or running scripts, Mastros gives you a structured export workflow inside Telegram Web.

Export it. Archive it. Analyze it. Keep Telegram data organized.
