tinefold: AI brainstorming for software decisions

Describe a software problem. tinefold proposes a handful of approaches, you choose one, it breaks your choice into sub-problems, and you keep choosing until everything is decided. It remembers why each option was rejected, flags decisions that may be out of date, and writes the result up as a PRD, TRD, solution design, decision records or a one-page brief.

No backend: everything runs in your browser and model calls go straight to Anthropic or any OpenAI-compatible provider with your own key. Without a key, demo mode shows the whole flow.
