In their own words
BrowserOS neo
BrowserOS neo is a free, open-source browser that lets AI agents operate through browser sessions you are already signed into. Agents can open tabs, navigate, click, and read pages while you remain signed in. The browser connects through MCP to Claude Code, Claude Cowork, Cursor, Codex, VS Code, Zed, and GitHub Copilot. Multiple agents can work in separate tabs while you browse. Each run is saved as a scrubbable video for replay. The maker says sessions, screenshots, replays, settings, and logins stay on your machine rather than being sent to its server. Chrome logins can be imported in one click. BrowserOS neo sends compact page snapshots instead of raw HTML and can batch actions in one call. It runs on Linux, macOS, and Windows, uses Chromium, and is licensed under AGPL-3.0. It is free, has no free trial, and requires your own AI provider keys.
Comet
Comet is Perplexity’s AI browser, with an assistant built into browsing. The assistant can answer questions about open tabs, search the web and interact with websites on the user’s behalf. Examples include summarizing or explaining content, comparing tabs, drafting emails, scheduling meetings and making purchases. Perplexity is the default search engine, and Comet uses Chromium. It is free to download at free for Android, iOS, macOS and Windows. Comet supports most Chrome extensions, though users must install and configure them again because extension data does not transfer from Chrome. The browser stores URLs, searches, cookies, open tabs and site permissions locally. Website credentials are kept in the device’s secure vault, not on Perplexity’s servers. Privacy settings allow deletion of browsing and search history, cookies and cached data. However, some queries may involve sending page context, including text or email, to Perplexity’s servers. Email or schedule tasks may require opting in to Perplexity Connector access; those permissions can later be changed or revoked. Comet says users can stop the agent and should review actions before confirming them.
