Cases

The same prompt sentence again — only the repo URL changed. We turned NextChat, the open-source AI chat client that keeps everything in the browser, into a multi-user product with SSO login, per-user isolation, and chat history persisted in platform storage. Refactor and go-live the same day; production E2E passed 6/6. This page gives the brief, verifiable test numbers, and the launch prompt archived verbatim.

One copyable prompt plus one GitHub URL: we turned Novel, the open-source notes app, from an open-access single-player tool into a multi-user product with SSO login, per-user document isolation, and the platform AI relay — the main refactor in one AI collaboration session, live on Vercel the same day. This page is the case brief: before/after, verifiable test numbers, and the launch prompt archived verbatim.
