Stop being the only ones who know how the product works.
Stewie reads your codebase and extracts product behaviors with evidence. The product contract becomes the shared language between engineering and everyone else.
Sound familiar?
You're the living documentation
Every product question routes through your team. 'Does the trial last 14 days or 30?' 'Can users downgrade mid-cycle?' You answer the same questions every sprint.
New hires take weeks to get productive
Onboarding means pairing sessions, codebase walkthroughs, and tribal knowledge dumps. There's no single place that explains what the product actually does and why.
PRDs drift from implementation
The spec said one thing, but you built something different because of constraints the PM didn't know about. Now there are two conflicting versions of the truth.
Refactors break undocumented rules
You clean up a module and accidentally change a business rule nobody wrote down. The bug report arrives two weeks later. Nobody realized that behavior was intentional.
How Stewie helps
Automated product analysis
Point Stewie at your repo (read-only). It maps modules, behaviors, and business rules — each with a confidence score and links to the source files that support them.
Evidence-backed behavior claims
Every behavior in the product contract links back to the code. When a refactor changes something, you know exactly which product decisions are affected.
Get the team off your back
PMs, QA, and leadership can read the product contract and confirm behaviors themselves. You stop being the bottleneck for product knowledge.
Catch drift before it ships
When the code changes, the contract surfaces what's affected. You see which behaviors shifted before they become a bug report or a confused PM in your DMs.
