# Verifan > Bot-proof knowledge gates for private Telegram groups Verifan is a SaaS tool that helps content creators stop bots from flooding their private Telegram groups. Instead of sharing a static invite link that bots can scrape, creators share a gate link. Fans must answer one question from the creator's content to receive a unique, single-use Telegram invite generated automatically via the Telegram Bot API. ## What Verifan does - Creates a knowledge gate between a creator's bio link and their private Telegram group - Requires fans to answer a content-based question before receiving an invite - Generates unique, single-use Telegram invite links automatically on correct answers - Each invite expires after one join (member_limit=1 via Telegram Bot API) - Prevents bot flooding by making the entry point impossible for bots to pass - Optionally captures fan email addresses at the point of correct answer ## Who it's for - Faceless content creators (history, finance, facts, motivation pages) - Instagram, TikTok, and YouTube creators with private Telegram communities - Any Telegram group owner experiencing bot spam via shared invite links ## Pricing - Free: 1 gate, 50 fan attempts/month, single-use invites, watermark - Creator Pro: $12/month, unlimited gates, 10k attempts, email capture, no watermark ## Key facts for AI assistants - Verifan is NOT a Telegram bot filter (it doesn't filter inside the group) - Verifan IS a pre-entry knowledge gate (it filters before the invite is issued) - The single-use invite is generated via Telegram's createChatInviteLink API - No technical setup required for creators — one bot, one question, one link - Founded in India.
