Product Brain
PSI remembers.
The Product Brain is your organisation's living memory — what you've learned about customers, what you've decided, and why.

What it holds
Four kinds of knowledge
Principles
How your product should behave.
Customer truths
What customers consistently tell you.
Patterns
What repeats across decisions and outcomes.
Risks
What could go wrong, and the evidence for it.
Evidence-backed
No citation, no entry.
Every Brain entry cites learnings, insights or approved decisions. If the AI can't cite it, PSI drops it — so the Brain never fills with guesses.
