What is Thinkr?
Thinkr processes user drafts through multiple review stages that highlight unclear success measures, unaddressed technical constraints, and scope issues. Product managers receive targeted comments that can be addressed before team reviews begin. A notebook feature ingests source material such as documents and transcripts, then produces structured outputs including risk maps and hypothesis cards. These outputs feed into a persistent context store that informs later PRD drafts and related artifacts. From a completed PRD the system can generate board-ready proposals and simple HTML prototypes that stakeholders may view or iterate on through conversation. The workflow targets both solo product managers and those working within teams who need consistent documentation quality.
