- Pros
- Every answer links its sources so you can check them instantly.
- Up-to-date, real-time information.
- One subscription to choose between OpenAI, Anthropic and Google models.
- Comet, a free Chromium-based browser with an assistant that acts for you.
- Cons
- Clashes with publishers (lawsuits from Dow Jones, The New York Times, Britannica, Reddit…).
- Limited free plan: about 3 Pro searches a day and 1 research report a month.
- Agentic-browser risks (prompt injection) and training on by default.
- Use cases
- Students, journalists and researchers who need sourced answers; professionals who want several frontier AIs with one subscription; anyone looking for a Google alternative for complex searches.
- Narrow the sources in the question itself (e.g. “only .gob.es sites and Spanish press from 2026”) and always open two or three citations before trusting a fact. If you use it for work, turn off “AI data retention” first.
- Privacy and data
- On Free, Pro and Max, “AI data retention” is on, so your queries may be used for training; turn it off in Settings > Preferences (only affects future data). On Enterprise, data is never used for training and files are deleted after 7 days.
