You’re on the list!

This experience is only available on desktop. Please open this page on your computer.

A different kind of privacy-first AI.<br>On your terms.

Unlike most AI assistants, Mozilla doesn’t keep your chat transcripts, use your conversations to train models, or sell your data. To keep Smart Window running reliably, we process limited technical information, like response times and token usage. Your chat content is only shared if you choose to share it.

“Memories” help Smart Window get more useful over time, without compromising your privacy. They’re stored on your device, not on Mozilla’s servers and we always try to filter out sensitive data, or data that is unique to you. You can see what’s been remembered, delete what doesn’t fit, or turn it off completely.

Research

A second opinion when you can’t decide

Smart Window highlights key points from what you’ve opened, compares options and shows you what stands out.

Summarize

An assistant when you don’t have time

Smart Window summarizes long articles, recipes and dense pages, so you get the essentials fast and keep moving.

Plan

A concierge when you don’t know where to start

Smart Window brings together takeaways from guides, reviews and your tabs, so you have a clear place to begin.

Built to put you in control

Use chat or search

We won’t ask you to change how you browse. Chat, search, or move between both in Smart Window.

There when you need it

Open Smart Window when you want help, then close it when you’re done. Get to it quickly from the toolbar.

Pick the model that fits

Choose from three models or bring your own. No lock-in, no defaults you didn’t choose.

Here’s what people are saying

The most value is when searching for a range within a product category and wanting to see different items with their prices. The side chat can explain the differences, while the webpage can show the actual products.

I was trying to be as vague as possible to the assistant to find past searches and I still got what I needed from history… this is pretty cool.

The most valuable part of the smart browser is how it interacts with each other… That to me makes the tasks that I am trying to accomplish very easy.

The window always being there allows me to increase how much I use AI. It allows me to interact with information as thoughts come up instead of waiting until I have the opportunity to look things up.

This smart browser was able to summarize/sift through the seller's account history and buyer reviews in a much shorter period of time than it would have taken me to do it manually.

I think Memories is interesting, especially for someone who does a lot of research, just kind of like keeping tabs of what they were researching, and their train of thought.
