A control layer that validates, repairs, and rejects AI outputs before users see them.
Product memo
Teams building AI products face a core challenge: AI outputs can be wrong, malformed, or off-policy, a problem prompts alone cannot reliably solve. Perf addresses this by acting as a correction layer between AI models and end-users. It fixes errors when possible and blocks untrustworthy outputs, allowing teams to ship AI products with greater confidence and reliability.

About Perf Expand
Perf provides a crucial control layer for teams building AI products, sitting between AI models and end-users. It solves the production challenge of AI outputs that are incorrect, malformed, or off-policy, which often slip past prompt engineering alone.
By integrating a custom rules engine, Perf validates every AI output, automatically repairing errors or rejecting those that cannot be trusted. This mechanism allows developers to deploy AI applications with increased confidence, knowing that user-facing content meets predefined quality and compliance standards.
