Let an AI edit a live web page through small, checkable edits instead of rewriting the file.

pagepatch sits between a model's reply and your saved page. The model writes small edits, pagepatch applies each on its own, refuses the unsafe ones, checks the rest landed and tells the model exactly what to fix.

Buy pagepatch for $99

One payment of $99, plus sales tax where it applies, and every future update. Delivered as a private GitHub repository you're invited to.

What it does

A small edit language: Nine directives a model can follow, with a parser that survives code fences, missing closers and awkward selectors.
Each edit stands on its own: Good edits are kept when others fail. A selector that matches nothing comes back with the closest real selectors, so the model corrects itself in one round.
The wrong element is never edited: When a selector matches several elements, nothing changes, and you get one selector per match.
Unsafe markup refused: Scripts, event handlers, javascript: URLs, frames and CSS that would freeze or blank the page are stripped or refused.
Checks that the change landed: Checks built from each edit run without a browser, or in one with the included verifier.
Works with any model: propose(llm, html, instruction) runs the loop. llm is any function from prompt to reply; there is no vendor SDK.

Try it

pip install ./pagepatch
pagepatch map page.html
pagepatch apply page.html edits.txt -o new.html

Questions

Do I need GitHub?: Yes. Access is a read-only invitation to a private repository, sent to the GitHub account you choose.
Can I get a refund?: Yes, within 14 days, no questions asked. Access ends when the refund goes through. Refund policy.
Who takes the payment?: Stripe. Your purchase is sold through Link, Stripe's checkout service, which also works out sales tax and sends your receipt.
Something wrong?: Email josephlinares02@gmail.com. Every buyer of a tool shares its repository, so support happens by email rather than in GitHub issues.
