Specifica Playground
Write a spec with an AI, then hand it to your coding agent. Start from an example (a CRM or an expense approval flow), level it up from Simple to Large, and ask for changes in chat. Every change applies at once and can be undone.
Export the .specifica/ folder as a zip, copy it for Claude Code, Cursor or any agent, or share it as a link. Free, no sign-up; chat uses your own model key, which stays in your browser.
