Turn your messy ideas into something actually buildable.
Stop wasting time. Turn your voice notes, rough docs, and half-baked ideas into clear plans for prototyping and building—so your AI Agents actually know what to make.

AI is helping you ship…
and wearing you down.
"You're here most days."
~23 re-prompts / feature
AI slop & drift
Your agents drift away from the original idea and you don’t have the energy to drag them back.
You keep saying 'good enough' because re-scoping feels like starting over.
Leads to features users don’t need and weeks of invisible rework.
AI fatigue
You’re re-explaining your product to ChatGPT or Cursor every week, across different chats and docs.
You treat LLMs like interns who forget everything on Friday.
You stop iterating because the context window is too heavy to lift.
Vibe PRDs
Specs live in random notes and half-finished PRDs; nobody could explain your product in one place.
Documentation becomes a 'nice to have' that you never actually have.
Agents hallucinate features because the source of truth is a vibe.
Context hell
You keep summarising, re-pasting, and losing nuance as the product grows.
Your prompt library is a graveyard of 'fix this' attempts.
You ship 80% of the wrong thing instead of 100% of the right thing.
Who we're building this for.
If you're not sure which one you are, you're probably a Vibe Coder.
Freelancers & Agencies
You rebuild context from Slack, Looms, and briefs every new feature. Specs change faster than you can version them.
One living product thesis per client. Every new feature is another node on the map, not a new folder of chaos.
Vibe Coders
You vibe into Cursor and patch drift as you go. Product thinking happens in your head, nowhere else.
Plan once, then vibe inside your IDE with agents that already know the story.
PMs & Founders
You chase PRDs across Notion, Figma, and Slack threads. Strategy lives in slides, reality lives in code chaos.
Go from business problem to AI-ready product thesis in one place. Bridge the gap between strategy and code.
Exec-Builders
You delegate product decisions but end up rewriting specs or debugging AI drift anyway. Leverage feels like a myth.
Use your time on decisions, not documentation. Review the map, approve the plan, then let execution flow.
Your product, indexed and explained.
The Product Index
- Connects ideas, features, constraints and iterations into one map.
- Queryable: answer ‘what does this feature depend on?’
- Reusable across features and versions.
The Product Thesis
- Your product, explained like a good junior–mid PM would.
- Assumptions, constraints, and edge cases in one doc.
- Sized for both humans and AI Agents.

How it works
From messy thoughts to agent-ready specs in four steps.
Drop in your mess
Upload docs, notes, call recordings, or just paste your existing PRDs.
We draft & ask
Our agent creates a first pass and surfaces questions about assumptions, constraints, and edges.
Refine thesis & index
Answer questions once; we update the thesis and index so it grows with your product.
Ship with agents
Use the thesis/index to drive Cursor/Lovable/other agents with far less drift and rework.
// From Product Thesis v0.3
feature: "Team invites"Each new feature walks this same path. The thesis/index just gets sharper.
Built by the very thing we’re building.
This entire landing page wasn't just coded—it was indexed. We fed our product thesis into Review My Product, and our agents generated the site you're scrolling right now.
Zero Hallucinations
The agents stuck strictly to the "Observatory" constraints defined in our index.
Rapid Iteration
We tweaked the thesis, not the code. The agents handled the refactor in minutes.

We're early. Here's the map.
We'd rather show you where we're headed than pretend we're done.
Toy
We are hereYou can build one serious product thesis + index and use it manually with your agents.
- •Single product thesis + index per product
- •Manual-ish review of outputs for depth & structure
- •Copy/paste exports to AI Agents
We add multi-feature awareness, branches, and better exploration.
Tool
SoonThe index knows your features and iterations, not just the current version.
- •Multi-feature index with branches & history
- •Exploration: find risks, contradictions, unexplored ideas
- •Light IDE/docs integrations
Becomes a live service your agents can query.
Weapon
LaterYour agents treat Review My Product as the live brain behind your product.
- •MCP server/API your agents query in real time
- •Deep integrations with Cursor, Notion, Figma, etc.
- •Acts as OS for your product decisions
Why we exist if you already have ChatGPT + Cursor.
Today's Workflow
- ✕Jump between chats and docs.
- ✕Re-explain product context every feature.
- ✕Specs live in random places.
Feels fast, costs you in drift & rework.
Traditional PRD Tools
- ~Assume you already think like a PM.
- ~One-off docs, not a product index.
- ~Too heavy for indie builders & agent-first workflows.
Great if you're a full PM team. Overkill for idea + agents.
Review My Product
- ✓Built for people with just an idea + AI agents.
- ✓Index + thesis reused across features & projects.
- ✓Planning layer that makes agents more reliable.
Your agents get a brain, not just better prompts.
// WHY THIS MATTERS OVER TIME
We're not 10x better at single prompts. We're 10x better once you've shipped your fifth feature using the same index.
We’re looking for 10–20 serious builders to shape V1.
You already use AI Agents (Cursor, Lovable, Replit, etc.).
You’re okay with early-stage tools if they care about your workflow.
You care more about better products than AI hype.
