In their own words
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.
Maxthon
Maxthon is a free Chromium-based browser with built-in notes, password management and an AI chat assistant. Signing in syncs bookmarks, settings, Maxnote, password-manager data and quick-access URLs across devices. Maxnote can record, organize, clip and share URLs, text, images and links. Maxthon 7 supports Chrome extensions, and its desktop versions can sync extensions between Windows and macOS. Reading mode removes ads and other page elements, Read Aloud converts webpages to speech, and split-screen browsing shows multiple pages in one window. Listed privacy tools include ad blocking, anti-tracking, incognito mode and a free VPN provided by Bright Data. Maxthon's privacy policy says searches through its default MaxAsk engine, which uses Google as its search content provider, involve collecting search queries, IP addresses and browser details. Maxthon says it encrypts account information and sensitive data stored locally or in the cloud, as well as data during account synchronization. Super Bookmarks requires a VIP subscription, and video downloads are limited for logged-in users.
