The PRD chatbot
Writes the doc.
Thinkr
Writes the doc, runs an 11-pass critique like your senior PM would, then turns it into the deck you’ll present on Friday.
From the founder
“Every PRD I shipped went out a little foggy, my team found the gaps in review, one sprint too late. So I built the senior reviewer I never had.”
Galang AuliaFounder, Thinkr
The loop
From a fuzzy idea to a board-ready deck.
One product, one context.
Your research, your draft, your critique, and your deck. All built on the same Brain.
Capture the context once.
Notebook ingests your research. Then it generates the artifacts you would have built by hand.
- Source ingestion: PDFs, URLs, transcripts, raw text
- RAG chat over your sources with citation chips
- Opportunity Solution Tree builder (visual graph)
- Studio: Risk Maps, Hypothesis Cards, Opportunity Briefs, Quote Walls, Assumption Test Plans
- Send to Brain so the context follows your future PRDs
Draft fast. Critique sharper.
A 4-pass PRD generator backed by your Brain. An 11-pass critique that names what is missing.
- Readiness Gate: pass/fail check before draft generation
- Context Scan: pull existing PRDs from ClickUp as reference
- 4-pass PRD generation: structure, gap repair, critique, strengthen
- Inline generation: user stories, acceptance criteria, edge cases, flow steps
- 11-pass Critique: completion, clarity of thinking, engineering readiness, flow coverage, edge cases, domain gaps, and a final verdict
- Quality scoring + PRD Insights surface the weak sections
Then ship the deck for Friday.
One PRD becomes a board-ready proposal and an interactive prototype. Without rewriting the story.
- Proposal: 2-pass deck generation (outline + slide fill) with Present mode
- Prototype: 2-pass HTML prototype generation, iterate via chat
- Public share links for stakeholders and external reviewers
- Version history with diff viewer across every generation pass
What Thinkr does
Seven surfaces.
One workflow.
PRD Generation
A 4-step flow: Coach, Context, Draft, Publish. The Draft step runs 4 passes (structure, gap repair, critique, strengthen). Inline help generates user stories, acceptance criteria, edge cases.
Learn more →Critique
11 passes across problem framing, success metrics, risks, assumptions, market alignment, technical feasibility, ethics, scope, dependencies. Findings land as PRD comments.
Learn more →Brain + Notebook
Notebook turns research into Risk Maps, Hypothesis Cards, Opportunity Briefs. Send the learnings to Brain so they follow your next draft.

Proposal
Auto-generate the board-ready deck from the PRD. Iterate with chat. Present in-app. Share with a public link.
Prototype
Generate an interactive HTML prototype from the spec. Refine through chat. Share with the design team.
Workflow chrome
Inline comments and mention threads. Version history with diff. Public share links that never expire.
Integrations
ClickUp shipped today, with Context Scan for pulling existing PRDs and tech docs. Linear, Slack, Jira, GitHub, Notion on the roadmap.
Teams already building with it.
Reviews
Loved by the people who build.
Who it’s for
Built for Product Managers.
Especially the ones with peers.
Solo Product Manager
One Product Manager, one product. Brain becomes your second brain. Critique is your sparring partner. Proposal turns the spec into the founder brief.
Product Manager in a team
Critique your draft before peer review. Share PRDs that respect your team’s context. Stop being the one whose PRD blocked the meeting.
Engineering-led founder
You think clearly. You do not want to spend Saturday formatting a spec. Thinkr handles the structure so you can focus on the bet.
How Thinkr is different
We know who we are up against.
Three tools you already know. Here’s where each one stops, and where Thinkr picks up.
The roadmap tool
Tells you what to build.
Thinkr
Helps you ship what you decided. We don’t replace your roadmap, we help you defend what’s on it.
The all-in-one workspace
Is a doc.
Thinkr
Is a workflow with a memory.

How to Write a PRD (That Survives Review)
CraftHow to write a PRD step by step, then write it so it survives review: the sections, the process, and the gaps a senior PM catches before engineering does.
Galang Aulia · 8 min readThe PRD review checklist a senior PM actually runs
CraftA copyable, 11-point PRD review checklist, what each check catches and the standard it maps to. The pass a spec should survive before it reaches engineering.
Galang Aulia · 7 min readHow Thinkr critiques a PRD: a worked example
CraftA walkthrough of an 11-pass critique on a real product spec. What it caught, what it missed, why the structure matters more than the model.
