Honestly didn't expect much. Most Telegram tools I've tried before are either sketchy bots that get my account flagged, broken Python scripts on GitHub, or weird desktop apps asking for permissions I'd never grant. So when I found this Telegram scraper as a Chrome extension I figured I'd test it on a throwaway account first. I'm now using it on my main one. What sold me: it just runs in the browser. No login wall, no separate server, nothing leaving my machine. Pulled members from a few of my mutual Telegram groups, deduped, exported to CSV. Used the same contact list the next morning for outbound outreach to a niche I'd been trying to break into for months. Two of them replied within the hour. If you're doing any kind of Telegram lead generation, prospecting, or community-driven sales, just install it. Simplest Telegram members extractor I've found in a category where most things either don't work or get your account banned.
