Know exactly what to build before you start.
HewnTree asks you questions about your idea and builds a structured brief from your answers. Hand it to a developer or use it to pitch. It works for software, and for books, games, events and research projects too.

Built for people who think in ideas
Founders, creators and small teams use HewnTree to turn something they can only half explain into something they can act on.
Solo Founders
You have a product idea but can't articulate it clearly to investors, co-founders, or developers.
Independent Creators
You keep cycling through the same vague concept and never make it concrete enough to act on.
Early-Stage Teams
Everyone on the team has a different understanding of what you're actually building.
What is HewnTree?
The short version, and a few questions people ask before signing up.
What is HewnTree?
HewnTree is an AI-powered idea definition platform. It takes your rough idea and turns it into a structured tree of requirements, covering everything from user flows to monetization to edge cases, by asking you targeted questions in batches.
What does HewnTree do?
HewnTree acts as a requirements gathering and product specification tool. It generates batches of AI questions about your idea, builds a live tree of definitions as you answer, scores each category for completeness, and exports the result as a clean PDF brief when you're done.
Who is HewnTree for?
HewnTree is for anyone who has ideas but finds them hard to pin down: founders, creators, small teams, writers, designers, students and planners. It handles software, mobile apps, creative writing, visual art, events and research projects.
How is HewnTree different from other AI chatbots or tools?
A chat tool is open-ended: you ask, it answers. That leaves you to work out what to ask, which is hard when the whole problem is that you can't yet describe the idea. HewnTree turns it round. You describe the idea in a sentence or two and it asks you the questions. It also keeps what you build. A chat ends with the conversation, so opening a new one starts you over, whereas HewnTree holds a scored tree that carries across sessions and exports as a brief. The AI underneath is much the same. What differs is what you put in and what you get out.
From vague to vetted in 5 steps
There is no setup. Describe your idea in a sentence or two and start answering questions.
Describe your idea
Type a rough description of what you want to build. It does not need polish; early and messy is what it is built for.
Answer AI questions
Our AI generates targeted question batches that surface the gaps in your thinking. You answer at your own pace.
Watch your tree grow
Every batch you commit adds nodes to your tree: categories, then subcategories, then the specifics under them.
Track your readiness score
A live score shows how complete your idea is. Hit your target across all categories to reach Ready status.
Export your brief
When your idea reaches Ready, export a PDF of the whole structure. It reads well enough to send to an investor or a developer.
Everything you need to define an idea properly
It is not a note-taking app or a mind map. You answer questions, and the structure builds itself.
Idea Tree
Your idea is structured as a living tree of categories, subcategories, and leaf nodes. Every gap is visible at a glance.
AI Question Batches
Questions aimed at the weak points in your idea. You pick the batch size: Small (10), Medium (20) or Large (30).
Readiness Score
A score per category that rolls up into one readiness percentage, so you can see which parts are thin.
Tree Comments
Leave feedback on any node. The AI processes it and updates the tree, creating a full change history.
PDF Export
When your idea is ready, export a clean, structured brief. Force-export at any time for a current-state snapshot.
Nudge Emails
Configure per-idea reminders so you never let an important idea stall. Every 2 days, every 4 days, or weekly.
