💳 AI Credits and Subscription

Celestory offers several subscription tiers. Each one grants a different monthly AI generation quota, and some features — including several blocks marked with a star ⭐ — only unlock from a specific tier upward. This guide describes the actual tiers, what happens once the quota runs out, and how to change plans.

🔎 The usage gauge in the AI Generation window, and the silent behavior of the AI text request block, are already covered in other articles. This one focuses on the subscription itself.

🪜 The Four Tiers

🔺 These are the figures shown in the interface at the time of writing. A custom plan adjusts this quota case by case.

Free trial

A starter account, active for 15 days from account creation. Besides the monthly AI credit, it includes: 1 app, 1 Go of storage, behavioral statistics, team collaboration with web sharing (no export), document recognition, visual recognition, voice recognition, HTML5 AI app, JS code import, and the Iframe block.

Personal plan (Pro)

Built for a solo creator: 5 apps, 1 Go of storage, a personal license.

Business plan (Organization)

The professional tier: 100 apps, 500Go of storage, a corporate license, behavior charts, team work, mobile and desktop export, document recognition, visual recognition, voice recognition, an HTML5 AI app, JS code import, and the iframe block.

Custom plan

No price is shown: its button leads to a sales meeting scheduler. This tier adds SSO authentication, additional projects, additional AI credits, additional storage, gamification creation, on-demand development, custom installation, and no-code AI training.

🧮 What Does an AI Credit Cover?

The monthly quota shown in the AI Generation window ("Monthly usage", with a reset date) covers:

• Text, Image, Video and Audio generations from the AI Generation studio,
• using the AI text request block in the graph, and the assistant that builds the graph for you.

Every model has a credit cost shown next to its name (e.g. "3 ©"), and that cost can differ from one model to another.

🔺 What Happens When the Quota Runs Out?

It depends on where you are:

• In the AI Generation window (Text, Image, Video, Audio): the generation fails and an error message is clearly shown on screen — this is not silent. The usage gauge turns red as soon as usage reaches the limit.
• In the graph's AI text request block: this behaves differently and is already documented elsewhere — in short, that block never signals a failure through a dedicated output, whatever the cause, quota included.

🔺 An expired subscription is not the same thing as an exhausted quota: an expired subscription cuts off access to entire blocks (see below), while an exhausted quota simply blocks the next generation until the monthly reset or an upgrade.

🔁 How to Change Plans

Open your account settings, Subscription tab. It shows your current tier and an Upgrade button, which opens the plan-selection page in a new tab. The same tab also has an Activation code field with a Redeem button, to apply a promo or gift code to your account.

On the plan-selection page, each tier has its own button (Start, Upgrade, Downgrade…); payment goes through an external provider, and an already-active subscription is redirected to its own management portal instead of a new checkout.

⭐ What About the Star Badge?

The claim already documented elsewhere is confirmed by the code: the star ⭐ shown in the add-block menu is a subscription-tier badge, not a credit-consumption indicator. Every block currently carrying that star — AI text request, HTTP Request, MCP, HTML5, Input Camera, Microphone, File selection — requires the Business (Organization) tier, never just Pro. A Pro or free-trial account cannot use them, even with AI credits left.

→ Next step: open your account settings to check your current tier and quota reset date before starting a large generation.
