Get Started Free
Market, competitors, tech debt, team size, constraints—before you write any PRD or roadmap. Claude should know this already.
You make a call on trade-offs, and it disappears. Later: why did we choose X over Y? You can't remember. Neither can your AI.
You draft in Claude on Monday and ChatGPT on Tuesday. Different AI sessions. Different voices. Different structures. No consistency.
Roadmap, OKRs, active initiatives—loaded automatically. Claude knows your product direction before you ask a question.
Store your trade-offs and decisions permanently. Why you chose architecture X. Why you cut feature Y. Never forgotten again.
Store your PRD template, writing style, and product voice. Every output matches your format and tone automatically.
Paste your roadmap, research, or decisions. CacheTank structures it instantly.
Add to Claude system prompt. Your product context loads automatically in every session.
Claude already knows your product. Write PRDs, roadmaps, and updates in minutes.
PMs store their product context—roadmap, OKRs, user research, tech constraints, decision log—in CacheTank. Load it into Claude, and suddenly Claude knows your product as well as you do. Write PRDs faster. Synthesize research faster. Make better decisions faster.
Use CacheTank's Cache it feature to paste your roadmap, user research, constraints, or decision log. CacheTank structures it and creates a /ctx URL. Add that URL to your Claude system prompt, and your product context loads automatically in every session.
Yes. Store your roadmap, user interviews, market research, and constraints in CacheTank. Every time you ask Claude to draft a PRD or synthesize user feedback, that full product context loads automatically. No more re-explaining your market or users.
Most PMs use Claude or ChatGPT for PRD drafting. The problem isn't the tool—it's that you have to re-brief on your product every time. CacheTank solves this by making your product context persistent and loadable, so any AI tool knows your roadmap, users, and constraints from the start.
Store your PRD template, writing style, and product voice in CacheTank's SKILLS layer. Every time Claude writes a PRD, roadmap update, or stakeholder summary, it follows your format and voice. Consistency across all product documents, automatically.
Pause anytime — 1, 2, 3, or 4 weeks. Your library waits for you.
