What platforms does Muddy support?

Muddy is available on MacOS, Windows, iOS, Android and Web App.

What are the limitations of Muddy?

Requires switching default browsers, and the homepage presents a Mac download first while other platforms are only listed in the footer, so availability by platform is unclear. The intelligence layer depends on reading tabs and conversations, which raises reasonable questions about how much workplace context is ingested and where it is processed. Collaboration features only pay off if the whole team adopts Muddy, so a single holdout reintroduces the app switching it is meant to remove.

What is Muddy?

Muddy is a collaborative browser where teams share spaces of apps and tabs, comment on anything inside them, rewind through shared history, and query an AI that reads open tabs and past conversations for context.

Muddy is a browser built for teams rather than for solo browsing. Instead of scattering work across tabs, chat windows and a dozen SaaS logins, it treats the browser itself as a shared surface. Colleagues create spaces together, and everything inside those spaces (apps, sites, files and conversation) stays visible and reachable to the group. The pitch is straightforward: the browser you already use becomes the place where collaboration happens, not another dashboard layered on top. Mechanically, three features carry most of the weight. Universal commenting lets anyone highlight text, mark an area of an image, point at a spot inside a site or tag a video timestamp, then send that context as a thread. Multiplayer presence shows what teammates are doing across projects, with one click to join them in the same app or conversation. Infinite rewind scrubs backward through the full history of apps, files and messages, reloading any state so someone can pick up where a colleague stopped. An AI layer reads open tabs and prior conversations, categorizes the workspace automatically, and answers questions with that context, asking follow ups when the request is vague. It fits teams that live in the browser all day: engineering, design, marketing and sales groups coordinating research or review work. Individuals can build a private space first and invite others later. Because Muddy supports anything that runs in a browser, including Chrome extensions, it can serve as a daily default rather than a side tool, and importing history, passwords and logins eases the switch. Cookies and passwords stay local, and tab hibernation handles memory and battery load. Alternatives split into two camps: tab managers and session-sharing tools that organize pages without conversation, and team chat products that discuss work without holding the work itself. Muddy bets that combining both in one client is worth adopting a new browser. Pricing is not published on the homepage, and the release page promotes a Mac download while the footer lists Mac, Windows, iOS and Android.

How do you use Muddy?

1Download Muddy and set it as your work browser
Request or grab the Mac download from the homepage, install it, then import history, passwords and logins so existing sessions carry over. Set Muddy as the default for work browsing when prompted.
2Build your first space
Create a space and open the apps and sites your project depends on. Muddy renders and categorizes tabs based on relevance, so the workspace organizes itself as you add material.
3Invite teammates into the space
Share the space with colleagues so presence indicators appear. Use the one click join control to drop into the same app or conversation someone else is already viewing.
4Leave contextual comments
Highlight text, select an image region, point inside a site or tag a video timestamp, then send the thread. Discussion stays attached to the exact element rather than floating in a separate channel.
5Rewind shared history
Scrub backward through the space to reload earlier apps, files and messages, then jump to any point and continue working in the app directly from that restored state.
6Put the assistant to work
Ask questions about the project. The assistant reads open tabs and past conversations, retrieves relevant sites and asks follow ups when the question is underspecified.
