  description

  Scrape and export structured data from Telegram Web — group members, chat messages, contacts, and mutual groups — from conversations you already have access to. Download clean CSV, JSON, or JSONL files in seconds.
  
  Try it free — no account, no email, no credit card. Install, open Telegram Web, and run your first extraction in under 60 seconds. The Free plan gives you 500 profiles and 1,000 messages every month, with full access to the Group Members and Mutual Groups scrapers. No trial countdown, no feature walls on core functionality. If it works for your workflow, upgrade when you're ready.
  
  
  ★ WHO IS THIS FOR?
  
  → Growth & marketing teams who need to scrape Telegram groups for outreach lists
  → Researchers collecting public conversation data for analysis
  → Community managers auditing member overlap across groups
  → Sales teams scraping prospect contacts from Telegram channels
  → Anyone who needs Telegram data in a spreadsheet
  
  
  ★ FOUR SCRAPING MODES
  
  ➊ Group Members Scraper
  Scrape complete member lists from groups and channels you belong to. Select from your group list, paste @handles or t.me links, or target the currently open chat. Deduplication across multiple groups built in.
  
  ➋ Chat Messages Scraper
  Scrape message history from any open conversation — text, sender info, timestamps, reply chains, and forwarded messages. Configure how many messages to collect (up to 100K).
  
  ➌ Recent Contacts Scraper
  Scrape profile data from your most recent conversations. Set how many chats to scan, filter out bots and pinned chats automatically.
  
  ➍ Mutual Groups Scraper
  Enter a @username to discover shared groups, then scrape member data from those groups in one flow.
  
  
  ★ TWO ENGINES
  
  Web Mode — reads directly from the Telegram Web interface. No setup needed. Works instantly for scraping Chat Messages and Recent Contacts.
  
  Power Mode — connects to the Telegram MTProto API for faster, deeper, and more complete scraping. Required for the Group Members and Mutual Groups scrapers. Available on Free tier for these two modes; unlock Power Mode across all scrapers with a paid plan.
  
  
  ★ EXPORT YOUR WAY
  
  • CSV — open in Excel, Google Sheets, or any spreadsheet tool
  • JSON — structured data ready for databases and pipelines
  • JSONL — line-delimited JSON, ideal for streaming and large datasets
  
  Each scrape runs as a session. Review, download, or clear sessions individually from the Export tab.
