v2.2 — live in the Chrome Web Store

Rebuild the internet, one prompt at a time.

Modify is a Chrome extension that turns plain English into permanent website fixes. Strip the ads, force a theme, simplify a layout, or automate tasks — without writing a single line of code.

Stop playing by their design rules.

Most of the modern web is hostile — paywalls, cookie banners, tracking scripts, and low-contrast ad bait. Modify gives you complete control over every site you visit.

Clean Up

Remove anything instantly.

Describe the nuisance — a sticky header, cookie banner, newsletter pop-up, or an annoying sidebar. Tell the AI what to hide, and it's gone. Every time you return to the site, the page stays exactly how you cleaned it.

Redesign

Make it look how you want.

Say "make this look like Stripe" or "use high-contrast yellow on black for readability." Modify instantly adjusts the colors, fonts, and layouts to match your requested style, saving it for your next visit.

Automate

Add useful shortcuts.

Wire a keyboard shortcut to a clunky search box. Auto-sort a messy dashboard table. Pre-fill a repetitive form. Modify builds these shortcuts directly into your browser to speed up your daily routine.

document.addEventListener('keydown', (e) => {
  if (e.key === '/') {
    e.preventDefault();
    // Jump straight to search
    document.querySelector('#search-input').focus();
  }
});
What's in the box

Built for people who want a better web.

Everything you need to design, save, share, and manage tweaks across the sites you use every day.

Just type or speak.

Type what you want to change or press the mic to say it out loud. Modify understands what you're asking for and instantly applies the changes to the page.

Smart auto-updating.

Websites change their layouts all the time. When they do, Modify notices the change, updates your tweak automatically, and asks you to approve it so things don't break.

Set it and forget it.

Your fixes apply automatically every time you visit the site. Clean it up once, and never deal with it again.

Group across sites.

Bundle your changes across multiple websites. Apply a distraction-free reading mode to every news site with one click.

Look under the hood.

Curious how it works? You can view, edit, and fine-tune the exact code Modify generates to make your changes happen.

Share with friends.

Export your favorite site setups to a file and send them to a friend, or import theirs just as easily.

Easy Export No account needed

Pick your AI.

Connect your favorite AI model—like Claude or ChatGPT—and use your own account to power the changes.

Built for privacy

Your web.
Your data.

Modify runs completely on your own machine. We don't track the websites you visit, the prompts you write, or the fixes you save.

  • Bring your own account for Claude, ChatGPT, or OpenRouter.
  • Saved securely on your device — never on our servers.
  • Works safely within your browser's trusted permissions.

Privacy Policy

Effective May 17, 2026 · v2.2

1. Introduction

This Privacy Policy describes how Modify ("we", "our", or "the extension") handles your information. We are committed to protecting your privacy and being transparent about our data practices.

By using Modify, you agree to the collection and use of information in accordance with this policy. If you do not agree, please do not install or use the extension.

2. Information We Collect

Information stored locally on your device:

  • API credentials: your API keys for OpenRouter, Anthropic, or OpenAI
  • User tweaks: your custom modifications including prompts, generated code, and target websites
  • Groups: organizational data for grouping multiple websites together
  • Preferences: theme, voice input language, AI provider selection, and other settings
  • Session state: temporary data to maintain UI state across page loads

Anonymous diagnostic information we may collect (opt-out):

  • A randomly generated installation ID, not linked to any personal information
  • Aggregate events: extension opened, fix generation started, execution success/failure, fix saved
  • Extension version and AI provider name (e.g., "OpenRouter") — never your API key, the model selected, or any request content

What we never collect:

  • URLs of websites you visit
  • Contents of your prompts or generated website fixes
  • Your API keys
  • Page contents from any site you visit
  • Any personally identifiable information

3. How We Use Your Information

All of your data is stored and processed locally on your device for the following purposes:

  • Core functionality: to save and execute your custom website modifications
  • Persistence: to remember your settings and fixes across browser sessions
  • Generation: to send your prompts to your chosen AI provider and receive the fix
  • Organization: to manage groups and apply fixes to multiple websites

Anonymous diagnostic events are used solely to understand aggregate product usage (active users, generation success rates, common failure modes) so we can improve Modify. You can disable diagnostics at any time in Settings.

4. Third-Party Services

When you use the extension, your prompts are sent directly from your browser to your selected AI provider:

Anonymous diagnostic events are sent to a small endpoint we operate on our own infrastructure. No third-party analytics processor, advertising network, or data broker is involved. We do not share or sell any data.

5. Data Sharing and Disclosure

We do not sell, trade, or rent any data. Your website fixes and API keys are stored locally on your device; we have no access to them.

You may choose to export your website fixes as files and share them with others. This is entirely optional and under your control.

6. Chrome Permissions

Modify requests the following Chrome permissions:

  • activeTab: to access and update the currently active tab when you click the extension
  • storage: to save your fixes, settings, and preferences locally
  • scripting: to safely apply your requested changes on websites you've chosen to modify
  • unlimitedStorage: so large libraries of fixes are not subject to a hard quota

7. Data Security

  • All script data is stored using Chrome's secure storage APIs
  • Your API keys are stored locally and never transmitted to our servers
  • We recommend using API keys with appropriate rate limits and spending caps
  • When importing fixes from others, review them before enabling them
  • Consider regularly backing up your setups using the export feature

8. Your Data Rights

  • Access: view all your stored fixes and settings through the extension
  • Modification: edit any stored data at any time
  • Deletion: remove individual fixes or use "Clear All Data" in Settings
  • Export: download your fixes as a file for backup or sharing
  • Diagnostics opt-out: disable anonymous diagnostics in Settings at any time
  • Uninstall: removing the extension deletes all locally stored data

9. Children's Privacy

Modify is not intended for use by children under 13. We do not knowingly collect personal information from children under 13.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will note any changes by updating the "Effective Date" at the top.

11. Contact

  • GitHub: open an issue on the Modify repository
  • Chrome Web Store: use the support section on the extension listing

12. Compliance

Modify is designed to comply with the Chrome Web Store Developer Program Policies, GDPR (EU), CCPA (California), and PIPEDA / Loi 25 (Canada/Quebec). Our privacy-first approach minimizes data-protection obligations by design.
