# Feature availability

This matrix summarizes IsonAI features by platform and plan. Cell legend: ✓ = available, — = not available, **Alpha** = publicly available with still-growing coverage, `*` = see the note in the rightmost column. The iOS column refers to the official iOS app; the website remains usable from any mobile browser — features marked "—" for iOS can still be used through the browser.

## How to read this matrix

- **Guest** = using IsonAI without an account. Guests get core chat (with model selection, Thinking, and web search) plus Ison Search; features that store or upload anything — images, documents, memory, folders, Naya, Slate, connectors, image generation — require an account.
- The **iOS** column reflects the currently released app version; the app is updated to follow the web version, so cells marked — may change in a future release (see the [release notes](/en/release-notes/)).
- Quotas and daily limits are explained in [Plans & quota](/en/plans/).
