Spec Diff Tool for Spec-Driven Development
In spec-driven development, the spec IS the product. When the spec changes, your AI agent needs to know exactly what changed — and so does your client.
Paste requirement text on both sides to compare.
Sound familiar?
- Spec files change silently; the agent builds from a stale version
- No way to show stakeholders the delta between spec versions
- Spec Kit / Kiro / OpenSpec track specs internally but can't share diffs with clients
Stop losing money to scope changes
BriefPort freezes your requirements baseline, prices every change, and keeps your AI agent building from the right version.
