Signal

Personal intelligence for builders

Signal collects open-web tech, AI, and crypto stories (RSS, Reddit, Hacker News), then scores them with Claude Haiku against a profile tuned to you—so you see opportunities and ideas worth acting on, not an endless feed.

You add your own Anthropic API key (encrypted in our database). We host the app, database, and scrapers with operator keys—nothing except your AI key lives in your hands.
