Prompt → change → rule auto-applies next visit

Start on our demo page so the first win is reliable — then use the same flow on any site you enable.
Honest limits

Safe mode by default: edits use declarative DOM/CSS ops (and sandboxed data widgets), so they still work on many strict-CSP sites. Freeform Explore stays off where a page blocks page-world scripts. Live charts need a real JSON HTTP API — LiveView-only data isn’t supported.

WHY PEOPLE LOVE IT

The web finally listens to you.

Stop working around terrible interfaces. Use natural language to fix, hide, reorder, or enhance anything. Your changes become permanent rules that run every single time you return.
Built for real work

Powerful features that actually matter

Natural language edits

Say what to change. We apply safe DOM/CSS ops on the live page — then you can save the result as a rule.

Persistent rules

Every saved change becomes a rule. Rules auto-match URL patterns and execute on page load with proper priority.

Smart Inspector

Click elements to target them perfectly. Supports multi-select. Works even on complex SPAs.

Placement & widget mode Advanced

Hover anywhere to insert new UI components (charts, buttons, tables) directly into the page layout.

Network explorer Advanced

Record real API traffic. Get AI-suggested widgets that use the site’s own endpoints.

Versioning & sharing

Full history of every rule. Roll back anytime. Share rules with teammates via secure links.

FOUR SIMPLE STEPS

Up and running in under 90 seconds

STEP 01
Pick a chip
Open the assistant and choose a page-aware remake — or type your own prompt.
STEP 02
Send
We apply safe DOM/CSS ops on the live page.
STEP 03
Save as rule
Successful edits save as a sticky rule for matching URLs.
STEP 04
Refresh
Reload — the remake should still apply, with no re-prompt.

Most edits finish in under a minute; complex ones can take longer.

HONEST LIMITS

What works — and what doesn’t yet

Safe mode by default: declarative DOM/CSS ops (and sandboxed data widgets) work on many strict-CSP sites. Freeform Explore stays off where a page blocks page-world scripts. Live charts need a real JSON HTTP API — LiveView-only data isn’t supported. No fake reviews here — try it yourself.

Questions people ask

Does it work on every website?
Most sites, yes — via safe DOM/CSS ops. Strict CSP can disable freeform Explore. Live data widgets need a fetchable JSON API, not LiveView-only sockets.
Is my data private?
The hosted product runs at https://addonsite.ai. Account data, rules, and prompts are processed on our servers so the extension can remake pages for you. See our Privacy Policy. Advanced users can still self-host the backend if they prefer full control.
Do I need to be a developer?
Not at all. Just describe what you want in plain language.
Can I share rules with my team?
Yes. Create a team, invite colleagues by email, and save rules to the team so they auto-apply for every member. You can still share individual rules via secure links.
One prompt. A page that stays fixed.
