| Where to use it | Web, iOS, Android, Windows and macOS; Comet browser; Sonar API. | Web, iOS, Android, Windows and macOS; Claude Code and an API for developers. |
|---|
| 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.
| - Writes in a natural style and follows tone and format instructions well.
- Very strong at coding with Claude Code, which completes whole tasks on a project.
- Handles long documents well (1M-token context on the 5.5 models).
- Artifacts turn a request into a web page, chart or tool you can share.
|
|---|
| 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.
| - Allowances run out in intense sessions, with five-hour and weekly windows.
- No image or video generator of its own.
- Training on by default for personal accounts (data kept up to 5 years unless you opt out).
|
|---|
| 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.
| - Writing and editing; coding and automation; analysing long documents; building mini-apps without coding.
- Before a long job, create a Project with your documents and standing instructions (tone, format, audience): you won’t have to repeat them in every chat and you’ll use less of your allowance.

| 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. | On personal accounts (Free, Pro, Max and Ultra) training on your conversations is on: if you leave it, Anthropic may keep them for up to 5 years; if you turn it off in Settings > Privacy, they are deleted in about 30 days. Business plans and the API are not used for training. |
