A place for the
stories you bring.
Castfolio plays the character cards you choose, on your own computer. Keep cards and conversations together, then return to a story when you want to read or continue.
Your cards, stories, and settings are saved locally. There is no product telemetry. When you use an online model, requests go directly from the app to your chosen provider, which may receive your conversation content.

Before you begin.
Which systems will it support?
The first release targets Windows on x64 computers. Minimum system requirements and a public version number will be confirmed before release. A Mac version is planned, with no release date yet.
Is a model service included?
No. You connect your own model service. Its account, API access, usage charges, and data policies are separate from the player purchase.
Where do character cards come from?
Bring cards you created or have permission to use. This site does not distribute community cards. Compatible with character cards in the V2 format.
Where is my data stored?
Cards, stories, settings, and saved API credentials are stored on your computer. Requests to an online model go directly to your chosen provider, which may receive conversation content. See the privacy policy for the data boundaries.
Does local mean it never goes online?
No. Local describes where the player runs and stores your data. An online model requires a network connection. There is no product telemetry, online activation, or automatic update service in the current edition.
What does the purchase cover?
The player layer, preconfiguration, and updates within the purchased major version. Future major version upgrade pricing is to be confirmed. Model service fees are separate. Open source license rights are unaffected.
Can I request a refund?
You can request an unconditional refund within 14 days of purchase, no questions asked. Email support with your order identifier and purchase date. See the refund policy for the process. No payments are currently accepted on this website.
