In their own words
KWatch.io
KWatch.io monitors social conversations for keyword mentions, sales signals, and competitor activity, then sends alerts. Keyword monitoring covers Reddit, X, Hacker News, LinkedIn, Facebook, and YouTube; users can also track Reddit or Hacker News posts and comments and get an alert when someone comments in the conversation. AI labels sentiment around detected keywords as positive, negative, or neutral. Alerts are available by email, Slack notification, or API webhook, and keyword rules support included and excluded terms plus language filters. Webhooks send a JSON-encoded HTTP POST for each result. A hosted MCP server can connect compatible clients using a KWatch API key; named clients include Claude, Claude Code, Cursor, and VS Code. The maker says monitoring refreshes per second, with notifications usually arriving within seconds and sometimes taking up to one minute during temporary congestion. Coverage has limits: LinkedIn and Facebook comments are not monitored, Facebook groups must be public, and YouTube checks video titles and descriptions rather than audio. Instagram and TikTok are not monitored.
