AI prototype → build-ready spec

Your AI prototype, handed over as a spec teams can build.

AI can build a high-fidelity prototype in minutes — but a prototype is not a brief. It looks finished while missing the requirements, rules, states, edge cases and validation logic developers need. HyperSemantic is the one-file template that turns it into a clear, build-ready specification.

The handover

A prototype shows what it looks like. A spec says what to build.

Between the two is where meaning usually leaks. The template closes that gap — in three steps.

1

AI prototype

A high-fidelity, clickable prototype — the kind you can now generate with AI in minutes.

2

The handover

Every screen, state, rule and edge case is read from the prototype — and tagged for how sure we are.

3

Build-ready spec

A clear specification for designers, product owners, developers and QA — ready to estimate and build.

Why this matters

Better handover, fewer assumptions.

Built for designers, product owners, developers and QA — so everyone works from the same source of truth.

Less ambiguity

Every requirement is tagged by confidence and priority. The team can see what is confirmed, what is a recommendation, and what still needs a decision — before any code is written.

Faster estimation

Screens, states and rules are documented up front, so development can understand scope early and estimate with fewer surprises.

Better QA

Acceptance criteria are written in Given / When / Then format, so QA can test against intended behaviour from day one.

Inside the template

Everything you need to build — and nothing you can’t trust.

These are the real building blocks of the document. No unverified assumptions, no guesswork.

“Ground everything, invent nothing.”

Every requirement traces back to a real prototype interaction or an agreed decision. Where information does not exist, the template says so — and asks the owner. Nothing is guessed.

Tagged for trust

Every claim carries a status

Confirmed Observed in the prototype. Safe to build.
Recommendation A suggestion — needs sign-off.
Needs confirmation A real gap that blocks work.
Missing information An unknown, flagged on purpose with a question for the owner.

“Missing information” is a feature. Unknowns are surfaced and owned, never quietly guessed — so nobody builds on a false assumption.

Prioritised for the build

MoSCoW, on every requirement

Must have The release fails without it.
Should have Important — can ship without it if forced.
Could have Desirable — first to be cut.

Priority sits beside confidence, so scope conversations start from facts rather than opinions.
