In their own words
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.
