# Plans & quota

## How the daily quota works

Every account has a **daily quota for the smart models** — Adaptive, Omni, and PRME — measured in **tokens** (roughly the length of your messages plus IsonAI's replies). The quota renews every midnight UTC (around 07:00 WIB), and today's usage can be seen in **Settings**.

**[LYT](/en/models/) does not use this quota.** When your daily tokens run out, IsonAI does not stop serving you:

- Answers automatically continue on LYT for the rest of the day, with a notice in the interface.
- If you lock the picker to Omni or PRME, the selection switches to LYT automatically; on Adaptive, requests are simply routed to LYT.
- Everything recovers when the quota renews.

## Plans

| Plan | Summary |
|---|---|
| **Guest** (no account) | A small number of messages per day, no history or memory |
| **Free** | Full daily quota for the smart models, all core features |
| **Pro** | A much larger daily quota for heavy use |

Currently **paid Pro is not yet open to the public** — Pro is granted through specific promotional programs. The latest plan details are always at [isonai.net/support](https://www.isonai.net/support).

## Feature-specific quotas

Some features have their own usage limits based on your plan:

- **[Deep Research](/en/deep-research/)** — a daily limit per plan.
- **[Ison Slate](/en/slate/)** — a daily limit per research depth.
- **[Naya](/en/naya/)** — Free: 3 missions/day (5 revisions per mission); Pro: 8 missions/day (15 revisions).
- **[Iris](/en/image-generation/)** — a daily image-generation limit per plan.

The limits that apply are shown in each feature's interface.

## Tips to save quota

- Leave the picker on **Adaptive** — light questions are automatically answered by the economical tier.
- Use **LYT** for casual chat; it doesn't touch the quota.
- Long conversations consume more tokens per message; start a new conversation when changing topics.
