An AEO tool that changes what agents receive

There are two kinds of AEO tool: the kind that tells you an answer engine could not use your page, and the kind that fixes it. This is the second kind, and the diagnostic half is free.

Diagnosis is cheap; the fix is the product

Nearly every tool in this category is a measurement instrument: it samples answers, or crawls you, and reports a score. That is genuinely useful once, and then it keeps reporting the same score until somebody changes the serving layer. The change is the part that moves the number, so the change is what this is built around.

What the tool actually does

It sits in front of your pages and answers content negotiation. A request that asks for markdown gets markdown, built from values you already store; a browser gets your normal page; a search crawler gets canonical HTML. Nothing is generated at request time.

import { gateway } from '@rebilder/gateway'

export default gateway({
  source: { kind: 'document', resolve: myPages },
})

On the reference product capture, that took a page from 91,226 bytes to 1,315 and moved the first substantive fact from character 23,185 to line 4, with the facts unchanged. There are adapters for common platforms, and the core has no framework dependency.

How to evaluate any AEO tool, including this one

  • Ask what it changes. If the answer is "it reports", budget for whatever will do the changing.
  • Ask whether the score is deterministic. A number that moves without your page moving cannot be used to judge a change you made.
  • Ask to see the spec. Ours is published, including the arithmetic, so a score can be checked rather than trusted.
  • Ask what it promises about citations. Anything guaranteed there is a claim nobody in this market can honour.
  • Ask what it uploads. Our command-line scanner sends nothing: no scan, no URL, no hostname.

What this does not do

Frequently asked questions

What does an AEO tool do?

Broadly one of two jobs: measuring whether answer engines can use your pages, or changing what those engines receive. Measurement is the common one and it is worth having; only the second kind moves the score.

Is there a free AEO tool?

The scan here is free and needs no account, and the gateway SDK is free, unmetered and self-hostable. The paid tier covers hosting and history rather than capability, and the serving path never checks a plan.

Do I need to change my CMS?

No. It runs as middleware in front of what you already have, with adapters for common platforms and no framework dependency in the core. Your theme, your analytics and your checkout are untouched.

Will this affect my search rankings?

No. Content negotiation returns the same substance in a different format and search crawlers keep receiving canonical HTML. Serving different prices or availability by requester would be cloaking; a format transformation of identical facts is not.
