Comet is Perplexity's full browser with a research-native sidebar and an action-capable agent. It plays differently than ChatGPT Atlas or Operator — and the differences matter.
ChatGPT Atlas leans heavy on personalization — your memory follows you across tabs. OpenAI Operator (now folded into ChatGPT Agent) is a remote computer that does the clicking for you. Comet is built around the research thread: every page you visit becomes context the assistant can answer about, and it can take actions on the pages you trust.
Comet is not the most polished browser. Tab management lags behind Arc and Chrome. Extension compatibility is uneven. If you want a browser that just gets out of the way, Comet is not it. If you want a browser whose default mode is 'assist with research,' it is currently the best in class.
| Browser | Default focus | Action capability | Best at |
|---|---|---|---|
| Comet | Research thread | Comet Max only | Cross-tab synthesis |
| ChatGPT Atlas | Memory + chat | Limited | Personalized search across sessions |
| Operator / ChatGPT Agent | Remote agent | Strong, autonomous | Hands-off task completion |
| Arc / Chrome + extension | Browse normally | Add-on | Power users who want choice |
The big idea: Comet is the research-thread browser. Atlas is the memory browser. Operator is the autonomous agent. Pick by what you actually do all day.
