Comet vs Opera Neon

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.

Opera Neon is a Chromium-based AI browser for macOS and Windows. It can open pages, research, fill forms, and create content for a user. Neon Chat uses open pages as context and supports image generation, video generation, photo-to-video generation, and web-app creation. Neon Do works with the current page, manages tabs, runs scheduled tasks, and connects with Google tools. Research agents include Deep Research, One-Minute Research, and Local Research. Neon Cards save instructions for reuse across Chat, Do, and Research Agents. MCP connections are supported, with Claude Code, Lovable, and n8n named as working tools. Connections are read-only by default; actions require permission, and Neon Do can be paused, stopped, or taken over. Opera says chats and workflows remain on its servers for 365 days, can be deleted, and are not used for training. An Opera account is required. The free plan includes basic AI chat, ad blocking, a free VPN, Browser CLI, and MCP Connector. Standard costs $19.90 a month.
