The **AI Generation** window opens from the editor, either through the **AI Generation** button (found in the file browser and in the project), or from the keyboard with `Cmd+Shift+G` (`Ctrl+Shift+G` on Windows and Linux).

It is organized into 6 tabs — a bit like the tabs of a web browser — each dedicated to a type of content you can generate with AI. In the order the interface shows them:

**Text** · **Video** · **Image** · **Audio** · **Generations** · **Tools**

The sections below present them in a learning order rather than in screen order: start with the Text tab, which is by far the richest.

At the top of **every** tab, a **Monthly usage** gauge shows your consumption as `3.25/30 ©`, followed by the reset date ("Resets on 1 October"). The bar turns red as soon as the limit is reached. Two small round buttons sit next to it: **+** and **?** — these are **documentation links** (credits on one side, generation help on the other), not a purchase button. To change plan, go to your account settings, **Subscription** tab.
### How many AI credits am I allowed each month?
The monthly quota depends on your Celestory subscription, not on a fixed number for everyone:

| Plan | AI credits / month |
| --- | --- |
| **Free trial** (no paid subscription) | **1** |
| **Personal account** (Pro) | **5** |
| **Organization account** (Business) | **30** |
| **Custom account** | On quote (extra credits) |

*(A legacy "Premium" tier still exists in the system and also grants 5 credits per month.)*

The counter resets on the 1st of each month. The full breakdown of tiers, prices and what happens when the quota runs out is in the dedicated article: [AI Credits and Subscription](../../../Découvrir%20Celestory/Découvrir%20Celestory%20v3/EN/Credits_IA_Et_Abonnement.md).
### What exactly consumes a credit?
A "credit" is not the same as "one action". The accounting is finer than it looks, and it is worth knowing before a long session:

| What you do | What the counter deducts |
| --- | --- |
| Send a message in the **Text** tab chat | **¼ of a credit** — 4 messages per credit |
| Launch an **Image / Video / Audio** generation from the editor | **1 credit** per generation |
| An **AI text request** block fired in-game | **0.01 credit** |
| An **AI image request** block fired in-game | **0.05 credit** |
| A generation that **fails** | **0** — failures are never charged |
| A tool call relayed by an **MCP** server | **0** — those exchanges are not counted |

The counter resets on the 1st of the month (UTC).

🔺 **The `©` badge shown next to each model indicates its relative cost** (a "3 ©" model is three times more expensive to run than a "1 ©" one). It is a useful signal when choosing, but it is not what the monthly counter deducts: today the "Monthly usage" gauge counts generations according to the table above, without weighting by model.
