Know which facts have gone stale.

Stale reads your company data, remembers every fact with its source, and flags everything built on a fact the moment it changes.

Every line agrees with the one it depends on.

Sample data. In your workspace, each line cites the message, ticket, email or page it came from.

Someone says it once, anywhere. Everything else catches up.

Stale reads each message, ticket, email or page, keeps the facts and decisions in it with the exact words, and compares them with what your company already believes. A repeat confirms. A contradiction replaces the old fact and flags what rested on it.

Works with

Anything that traces back to a stranger can’t act.

Guests, shared channels, bots and unknown senders are untrusted. Stale remembers what they say, but nothing derived from it can trigger an action, and it can’t overwrite what your team already knows without someone approving it.

  • TracedEvery blocked action shows the exact chain back to the message that tainted it.
  • ReviewedRisky or low-confidence changes wait in a queue, with the old and new value side by side.
  • RevokedIf a human approves a blocked action and a new problem appears, the approval is withdrawn.

Give your agents a memory that can say “I’m not sure that’s still true.”

Connect any agent that speaks MCP. It can remember with sources, explain an answer, check an action against the firewall, and repair stale knowledge. It can’t approve its own blocked actions; that stays with a person.
