A chat writes text. Concept Drafts makes a plan.
A general AI chat answers in paragraphs. A concept draft is a finished page with the same sections every time, kept as versions in your account.
A page, not a chat
Specs table, labelled drawings, a priced parts list and build phases, laid out to print or save as a PDF.
Checks its own work
Every draft is checked before you see it: missing sections, broken drawings and gaps are fixed on the way.
Prices every part
Each part has a typical spec, quantity, a price range and the kind of supplier that sells it, added up into a budget.
Checked at every step
What happens to every concept draft before and after you see it.
Checked before you see it
Every draft is checked automatically for a complete page, working links and images, and problems are fixed on the way.
The same sections every time
Overview, specs, drawings, how it works, parts, phases, rules, who to involve and open questions, in that order.
Ranges, not made-up numbers
Estimates are marked approx. and prices are given as ranges, with a note that they must be confirmed.
Planning-only banner
Every draft says at the top that it is not a build plan and must be checked by a qualified professional.
Fits paper and phones
A Print or save as PDF button, and tables and drawings that fit a phone screen.
Unsafe requests refused
Weapons, explosives, devices to hurt people or animals, spying devices and drug making are never drafted.
AI second opinion
On paid plans, a fresh AI review lists what is missing or unclear in your project, most important first.
Whatever you're making, it knows the field.

Frequently asked questions
What can I draft?
Almost anything physical: boats and vehicles, trailers, small buildings, furniture, machines, drones, solar systems and products. Weapons, explosives, devices meant to hurt people or animals, devices to spy on people and anything to make drugs are never drafted.
Is it a blueprint I can build from?
Concept drafts are for planning, budgeting and talking to professionals. They are not engineering or build plans. Have a qualified professional check any design before you build or use it.
How long does a draft take?
About a minute for most ideas. Bigger ones build in the background and take 1 to 3 minutes.
What does it cost?
Concept Drafts are on every paid plan, from $9.92 a month (first month $1). A draft uses AI credits like a website build; Starter's monthly credits cover dozens of drafts. Discuss chat is free on paid plans.
Can I change it?
Yes. Ask for another size, budget or material in plain English. Every version is kept, so you can go back.
Can I print it?
Yes. Each draft has a Print or save as PDF button and is laid out for paper and phones.
Does a person check it?
Every draft is checked automatically, and on paid plans you can ask for an AI second opinion. It is not an engineering review: have a qualified professional check the design before you build.
Is my idea private?
Your projects stay in your own account and you can download all your data any time.
