AI Buildability
Can AI build most of it?
How much of the product a coding agent such as Codex or Claude Code could reproduce today.
HIGHValidate before you build
AI can build your product. Can it defend your business?
We stress-test your startup idea for AI buildability, commoditisation risk, moat strength and demand evidence, so you can build what lasts, not just what is possible.

Ideas are easy.
Enduring businesses aren't.
Five angles. A clearer view.
A sharper way to evaluate your idea.
Coding agents made building cheap. That moved the risk. We look at your idea across the five places it now lives.
Commoditisation Risk
How easily can it be copied?
Whether clones can offer the same value cheaper, and how crowded the category already is.
MEDIUMMoat Strength
What makes it defensible?
Data, contracts, community, approvals, assets: the things a competitor cannot prompt into existence.
LOWDemand Evidence
Is there real demand?
Payments, pre-orders and conversations count. Likes, waitlists of friends and "great idea" do not.
LOWFounder Edge
Do you have a unique angle?
Your background, network, audience and point of view. Why you, and not the next person with the same prompt.
MEDIUMExample ratings: an AI travel planner for families, from a founder with an audience and customer interviews. Read the full sample.

AI pressure test
Founder magnetism: four questions no score can answer
- Point of view. What do you believe about this market that most people in it would disagree with?
- Risk. What bold thing are you doing that competitors would not dare copy?
- Expression. What would people describe to a friend after using it?
- Change. If you disappeared tomorrow, what would customers actually miss?
Inspired by Alex M H Smith's writing on the charismatic business: when competence is cheap, attention goes to companies people find compelling.
These indexes come from transparent rules applied to your own description. They are not market research and not a probability of success. How the scoring works.
The question every founder now asks
Can Codex or Claude Code build my idea?
Often, yes. That is exactly the problem. Here is where coding agents stand in October 2026.
CAN What a coding agent can do today
- Landing pages, dashboards and a working SaaS MVP
- Login, payments, database and a basic API (with testing and a security review)
- AI chatbots, automations and content workflows
- Competitor and market research, when it has access and someone checks the sources
- SEO content and marketing material, with no promise of reach
- Pricing and strategy scenarios
CAN'T What it cannot do on its own
- Prove that a real customer will pay
- Acquire the rights to original or licensed data
- Create a community that actually turns up and stays
- Deliver physical services: people, kit, vans, rooms
- Hold a licence, an insurance policy or legal accountability
- Win contracts, suppliers and partners
- Know for certain whether competitors will enter your market
Our rule is not "if AI can build it, give up". It is this: if AI can copy the whole product, the customer can get the same value cheaper, and you have no clear edge, change the idea before you spend months on it.

Test firstVerdict
Verdict
Test First
A real audience, but the software is easy to copy. Narrow the wedge, then validate with a paid pilot before building more.
Key takeaways
- Several funded AI trip planners already exist, so the planner alone is not a business.
- The founder's family-travel audience is the asset; the code is not.
- Narrow the wedge: for example UK school holidays with young children.
- Test a paid pilot with 20 families before building more features.

Common questions from founders
Straight answers. No waffle.
Everything you need to know before you get started.
?
Is this just AI hype?
No. The free check is a set of published rules, not a chatbot. Paid audits use AI for research, and a person checks every source and writes the verdict.
?
Will this tell me exactly what to build?
No. We tell you where your idea is exposed and which test would change our mind. The decision stays yours.
?
Do I need a credit card?
No. The Reality Check is free with no sign-up. For paid audits we email a payment link only after you agree the scope.
Not for the Reality Check: it is free with no sign-up. Paid audits are paid by card through Stripe, and you get a full refund if we cannot take your idea on.
?
What makes this different from other idea validators?
Most score market size. We ask a newer question: if anyone can build your product in a weekend, what still makes customers choose you?
?
Will you give me a success percentage?
No, and be wary of anyone who does. Nobody has calibrated data for that. We give separate indexes, each with the reason behind it.
?
What happens to my idea?
The free check never leaves your browser. If you request an audit, we store your request privately, never publish it and never share it. See our privacy notice.
