Pros	Clean Python API Strong role/goal abstractions Active community Hosted platform for deployment	Agent can actually act on live sites — send email, book, buy, fill forms — not just answer questions about them. Assistant has direct access to the current page and other open tabs, so answers stay grounded in what you're looking at. Chromium-based, so existing extensions, logins, bookmarks and Chrome workflows transfer without friction. Free tier is generous since October 2025; you don't need a Pro sub to try the core agentic browsing experience. Answers are cited back to source URLs, inheriting Perplexity's citation-first UX. Cross-platform: macOS, Windows, Android and iOS all supported.
Cons	Production observability still maturing Debugging multi-agent flows is hard	Security researchers have demonstrated prompt-injection style attacks ('CometJacking') that can exfiltrate data from connected accounts — a real risk when granting the agent Gmail or calendar access. Agent runs on complex sites (checkout flows, dashboards) are still brittle and often need supervision or correction. Best models and longest agent sessions are gated behind Pro ($20/mo) or Max — the free tier throttles the most useful capabilities. Installing a whole new browser is a bigger commitment than a Chrome extension for users who just want an AI sidebar. No public API for the Comet agent itself; automation has to happen inside the browser UI, not via a callable endpoint. Privacy footprint is significant — the assistant sees page contents, tabs and, if authorised, mailbox and calendar data.
