Astra

Astra is the kind of tool that makes compliance teams actually sleep at night instead of having nightmares about PHI floating around in LangSmith traces. It tokenizes your sensitive data before it ever touches your agent's context window, so your LLM reasons on meaningless tokens while the real values only materialize at execution — which means your audit logs show semantic tokens, not actual SSNs and credit card numbers. Two lines of code, works with any agent framework, and it just dropped this week already sitting at Day Rank #12 on Product Hunt. If you're building AI agents on regulated data and haven't thought about this yet, Astra's about to become your new best friend.
