Comet vs DuckDuckGo Browser

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.

DuckDuckGo Browser is a browser for Android, iOS, macOS, and Windows, with a free plan and paid subscriptions. It blocks third-party trackers, including those from Facebook and Google, and most ads, including video and YouTube ads. It can block most cookie pop-ups and may opt users out automatically. Cross-device sync and a password manager are included, and a one-click control clears tabs, history, and browsing data. Email protection blocks hidden trackers in emails, while Duck.ai offers optional private chats with popular AI models. DuckDuckGo says those conversations are not used to train AI and that it does not track searches; its tracker list and exceptions are open source. Paid plans add VPN protection, advanced AI models, personal information removal, and identity restoration. Plus costs $9.99 a month or $99.99 a year. Pro costs $19.99 a month or $199.99 a year and adds Claude Opus 4.8, GPT-5.6 Sol, higher reasoning effort, and twice Plus’s Duck.ai usage limits. DuckDuckGo has been independent since its founding in 2008 and is based in Paoli, Pennsylvania.
