Overview

Build your own features into the websites you already use instead of adding another app to your workflow.

Edit the apps however you like to improve your existing workflow. No need to pay for expensive additional features, just vibe edit them into the apps you use already. What you can do • Build your own features into your workflow • Connect the web apps you use to external APIs • Add behaviour and shortcuts on top of existing sites • Connect two websites which never connected before • Access your data on websites without setting up connections. You being logged into the browser is enough. • Add right-click actions • Local persistent storage How it works 1. Create a CSS or JS file using the provided prompt 2. Add the file to alter 3. Reload the tab For JavaScript rules on sites with strict CSP, turn on “Allow User Scripts” on the extension’s details page in Chrome (Chrome 138+). Rules, secrets, and rule data stay on your device. alter does not send your browsing history to the developer. If a rule you enable calls an external API, that request goes only to the URL that rule uses.
