CharaSync

Note before using it: upload only references you own or have permission to use, and no output is guaranteed cleared for commercial use.
- Reusable character/object reference library, up to 4 images, with saved history.
- Samples published with reference, model, ratio, resolution and prompt, as API tests.
- FAQ sets out credit terms: confirmed failures are refunded, pack credits never expire.
