Best AI Browser Extensions

AI tools that work right inside your browser — Chrome, Firefox, Edge, and Safari. Summarize pages, draft emails, translate text, and more without switching apps.

Why use AI inside your browser?

Browser extensions sit one keystroke away from whatever you're doing. Instead of copy-pasting text into ChatGPT or switching to a separate app, you can summarize, rewrite, or translate the page you're already on. The best extensions for AI workflows do one of these well:

Writing assistance — drafting emails, fixing grammar, changing tone
Page summarization — condensing long articles to bullet points
Translation — inline translation that preserves page layout
Research assistance — answering questions about the current page
Coding helpers — autocomplete in GitHub, Stack Overflow answers

Looking for standalone AI tools, mobile apps, or free options?

Frequently asked questions

Are AI browser extensions safe?: Mostly yes, but check permissions before installing. Be cautious of extensions that request access to "all your data on all websites" — that's necessary for many AI extensions but it does mean trusting the publisher.
Do these work on Firefox / Edge / Safari?: Most are Chrome-first. Many publish Firefox and Edge versions; Safari support is rarer (Apple's WebKit has different requirements). Check each tool's listing for supported browsers.
Will browser extensions slow down my browser?: Quality extensions are lightweight. A poorly-built one can add 50-100ms to page loads. If your browser feels sluggish, disable extensions one at a time to find the culprit.
