Licencing Information

What is a Charisma developer licence and why do I need one?

A Charisma developer licence is required if you want to create interactive stories that live outside of our Charisma mobile app. For example, if you want your story to appear on your website or would like to use Charisma to power the dialogue and action in your Unity or Unreal Engine game, you would need a Charisma developer licence to do this.

What does a developer licence give me access to?

When you activate a developer licence on your account it unlocks two additional story types: 'Web' stories and 'Game' stories. These stories expose an API key on the story overview screen which can be used in any of our SDKs to link the story to your web, mobile or game experience. 'Web' stories follow a linear story structure, whereas 'Game' stories enable a non-linear story path.

How do I activate a developer licence?

To activate the licence, head to your account page, scroll down to the “Licences” section and click “Claim trial licence”. This will add the trial licence to your account.

Before you can use it, review the terms and conditions, and then click “Activate trial licence”.

Is developer licence free?

Once activated, a developer licence comes with a one month free trial period. This trial includes 20,000 free events and unlimited stories. Once the month has expired or you have used up your free usage, you'll need to purchase a usage bundle to continue using the playthrough features.

What are usage bundles?

Usage bundles are blocks of events. The number of events in each bundle depends on the bundle chosen. Usage bundles are pre-purchased and the events in those bundles are deducted as they are triggered by Charisma in a playthrough. For example, an event would be triggered when a character says something, a player responds, a player taps to continue or when they resume a playthrough.

Why do we charge for usage?

We've tried to keep costs as low as possible to make Charisma accessible to as many people as possible. That said, as all our infrastructure is hosted in the cloud, the more stories Charisma powers, and the more people who play those stories, the higher our hosting costs become.

Where can I see my event usage and licence details?

On your account page there is a licence section which displays the events you have remaining on your usage bundle(s).

The billing tab in the licence section is where you can purchase usage bundles too.

Where do I view invoices?

Your invoices can be accessed via the billing dashboard button at the bottom of the billing tab. You will also receive a receipt for your purchase via email.

What usage bundles does Charisma offer?

We currently offer 3 bundles to suit small to larger scale projects. The larger the bundle purchased, the smaller the cost per event. All bundles are a one-off purchase and expire 12 months after the purchase date.

If you are looking for a larger bundle of events or require a fixed cost for your project please contact us at with more information about your project and we'll arrange a follow up chat.

What are the costs?

The current usage bundle pricing is:

  • US$63 - 20,000 events
  • US$210 - 80,000 events
  • US$350 - 160,000 events
