quick answer

Cuttlefox is an AI webpage editor for Chrome.

It helps you customize websites without code. Tell Cuttlefox what to change on the page, and it generates a script that runs in your browser every time you visit that site. You can also ask it to build small tools that save data locally — notes, history, tracked values — using your browser's storage.

Use it as a no-code userscript generator, an AI website customizer, or a personal browser automation tool for the small webpage fixes that would otherwise need custom JavaScript. See the how-it-works guide or browse common questions.

What it is
An AI Chrome extension that edits webpages — and builds small page tools — from natural-language instructions.
What it replaces
Manual CSS tweaks, one-off userscripts, custom browser automation, and extra niche extensions.
What it saves
Your scripts plus any data they collect — notes, history, tracked values — stored locally in your browser.
works on any site

Your browser, your rules.

Most websites are built for everyone. Cuttlefox lets you tune them for you — add missing information, hide distractions, reformat layouts, fix annoyances, or wire up personal tools that keep their own data.

The change is yours. It runs locally, silently, every single visit. Scripts and any data they store stay in your browser — not on Cuttlefox's servers. No extensions fighting with each other. No scripts breaking after updates — Cuttlefox detects that and offers to fix it with AI.

use cases

What can you do with an AI webpage editor?

Cuttlefox is for personal website changes that are too specific for a normal browser extension and too small to justify writing code.

  • Hide distracting website content

    Remove Shorts shelves, promoted posts, cookie banners, popups, recommended feeds, or any repeated block that gets in your way.

  • Fix pages that are hard to use

    Pin table headers, widen cramped layouts, stop ad-driven page jumps, or make dense pages easier to scan.

  • Add useful information to pages

    Ask Cuttlefox to add price-per-unit labels, highlight matching terms, reformat product listings, or surface details already on the page.

  • Build tools that remember data locally

    Track values over time, keep personal lists, or attach notes to page items. Scripts can read and write browser storage — nothing leaves your device.

prompt ideas

Say it, and it's done.

Anything you'd describe to a developer — including tools that read and write local data — you can ask Cuttlefox.

  • "Make LinkedIn less depressing"Hides hustle posts, humble-brags, and "excited to announce" energy
  • "Remove the Shorts shelf from YouTube"Gone. Every visit. You're welcome.
  • "Remember which articles I've already read"Marks them locally so your feed stays fresh on return visits
  • "Track a product price on this page over time"Saves a snapshot each visit in browser storage and shows what changed, so you can see if it goes up or down
  • "Add a notes field to each row in this table"Your notes stay on your device, tied to that page
  • "Hide all the calorie counts"For when you just want to enjoy the menu in peace
  • "Stop the page from jumping when ads load"Reserves ad space so the content stops shifting mid-read
  • "Pin the table header when I scroll"Keeps column labels visible on that one spreadsheet-style site
  • "Remove the cookie banner that keeps coming back"Dismissed once, gone forever — even after a refresh
how it works

Three steps, then it just works.

No configuration. No account until you're ready.

  1. 01

    Open on any page

    Click the Cuttlefox icon in your toolbar, or press Ctrl+Shift+E. Cuttlefox asks for permission to read the page. The panel slides in alongside the page.

  2. 02

    Describe your change

    Type what you want in plain words. No selectors, no code. Cuttlefox reads the page and figures the rest out.

  3. 03

    Done. It sticks.

    The change saves to that site and runs automatically on every future visit. If it stores data, that stays in your browser too.
