F5Bot monitors Reddit, Hacker News, and Lobsters for keywords, checking submissions and comments for new content every few minutes. It emails alerts when matches appear. Filters can narrow results by subreddit, exclude terms, require other terms alongside a keyword, or target titles, bodies, URLs, or usernames. Select plans add AI filtering that uses a natural-language description instead of exact keywords. Depending on the plan, alerts can go to Slack or Discord through webhooks, or arrive as RSS and JSON feeds. API-enabled plans support programmatic alert management and webhook callbacks. Eligible plans can disable email, group alerts after a delay, or schedule daily digests at up to three chosen times. The maker lists brand monitoring, competitor intelligence, lead generation, and content or PR tracking as use cases. The free personal plan allows five keywords, while paid plans raise keyword and alert limits and add features.
Who it is for
It suits people tracking discussions, brands, competitors, leads, or public relations across the three supported communities. Teams needing integrations or API access need eligible paid plans.
