# BuzzGlean

> Describe the posts you want to find. BuzzGlean searches Facebook, Reddit, X, LinkedIn, TikTok, YouTube for your keywords, watches the groups, subreddits, review sites and app stores you pick, and alerts you by email, Slack or your AI agent when one appears. 7-day free trial.

BuzzGlean is an AI alerting tool for posts in communities, review sites and app stores. You pick the pages to watch (Facebook groups, subreddits, review sites such as Trustpilot, G2 and Capterra, app stores, blogs and forums), describe the posts you care about in plain language, and AI sends you only the posts that match, by email, Slack, Telegram or webhook. Everything is also available through a REST API and a remote MCP server for AI agents.
