I would like to hear more of you have a roadmap. This is what everyone is forgetting with all the AI stuff. No trust layer or governance.
You’re right. Most teams are shipping AI without a real trust layer. PromptBrake starts with deterministic security testing, then expands into CI gates, policy checks, audit-ready reports, and trend tracking so trust becomes part of release
@ajirjees88 - I work in the Service management space if you want to add the process layers and build this out. Happy to connect
@info2063 - Appreciate that. I agree that layer matters longer term, but for the MVP I’m deliberately staying focused on the core problem first: deterministic testing and clear security findings for AI APIs
Howdy, excited to share PromptBrake. I built it because testing AI APIs for security was still too manual, and I wanted a simpler way to catch issues before release.
