Built with GPT-6 Astra

Before you launch,
look for the
missing proof.

Turn one landing page into a focused launch review. Clear priorities, on-page evidence, and fixes you can act on.

Your audience. Your goal.
A second look, grounded in your page.

Put your page to the test.

Start with a public landing page and one action you want visitors to take.

Your landing page and launch intent

One public HTTP(S) page. No sign-in required.

Free during the challenge launch · HTML assessment only · 45-second server limit
The $0.25 amount is an internal estimated API-cost ceiling, never a charge to you.

Its URL, text excerpts, audience, and goal are sent to OpenAI. Don’t include secrets. Privacy & limits

Less guesswork. More context.

From page to priorities.

01

Define the intent

A page only works in context. Tell us who it serves and what their next step should be.

02

Read the source

LaunchProof extracts bounded HTML text: headings, descriptions, action labels, and body copy.

03

Make the next edit count

GPT-6 Astra interprets that evidence, infers the journey, and recommends fixes ordered by severity.

Inside your review

A judgment you
can trace back.

Every finding connects an interpretation to captured source text. Inspect the evidence, consider the fix, and make your own call.

Evidence IDs link each finding to the text supplied to Astra.

Usage receipt

Model, token counts, and estimated inference cost.

Useful because it’s bounded

A second opinion.
With the limits in plain sight.

One page. Read-only.

Only public HTTP(S) targets are accepted. Private networks and unsafe redirects are blocked. We never sign in, submit forms, make purchases, or change the target.

HTML, not a browser test.

No scripts execute. Layout, mobile behavior, accessibility compliance, performance, and working interactions are not verified. An inferred journey is not an executed test plan.

Your content & privacy.

Submitted context and page excerpts go to OpenAI. This app does not save reports or request stored model responses. Metadata-only usage receipts are logged. Provider retention policies may still apply.

Bounded cost. Human judgment.

Each audit has a 45-second server deadline, a 1,800 output-token limit, and a $0.25 estimated cost ceiling. Rate and spending limits may pause access. Scores and findings are AI judgments, not guarantees.
