A shared understanding. Better work.
A workspace for defining products, running the business, and working with AI. Built around decisions people can review.
Why this product exists
Good work starts with a shared understanding of the product. CrystalSpec gives teams a structured place to define it and keep decisions useful as the work changes.
Connect flows, roles, data, and tests. Review AI proposals, publish revisions, and share approved context with coding agents.
Product principles
Structure makes ambiguity visible
Flows, roles, data models, and test cases expose relationships that a long page of prose can hide.
AI proposes; people decide
Generated work is useful when its status is clear and a human owns the decision to publish it.
History is part of the product
A revision should show what changed and preserve the context behind accepted product behavior.
What we claim—and what we do not
CrystalSpec is built for product specification and delivery context. It does not claim to replace source control, architecture documentation, issue trackers, or regulated requirements systems. Our comparison library describes those tradeoffs directly, including cases where another tool is the better fit.
