CharaSync
AI character consistency across images and videos
About CharaSync
CharaSync is a reference-guided AI image and video generator built around one problem: keeping the same character or object recognizable from one generation to the next. Ordinary text-to-image tools redraw a face, outfit or product slightly differently every time, which breaks a comic, a campaign or a recurring social media persona. CharaSync lets you save references for a character or a product once and call them in later prompts, so new poses, outfits, scenes and short videos stay anchored to the same subject.
Image generation uses GPT Image 2.5 at up to 4K, video generation uses Seedance 2.0 at up to 1080p and 15 seconds, and an optional smart rewrite step reorganizes your request into a clearer prompt before generating. The site states that the models are accessed through APIMart, while CharaSync provides the reference library, the creation interface and the generation history. It is maintained by an independent creator based in China and started in 2026. The site is open about limits: references constrain the output but do not remove model variability, and faces, lettering and motion still need human review. Its usage rules require references you own or have permission to use, and prohibit sexually explicit content, non-consensual intimate imagery and deceptive impersonation.
- •Add a reference: upload a clear primary photo of the character or product, plus side views or detail shots, and give it a name. Up to 4 reference images can guide a generation.
- •Write a prompt that calls the saved reference and describes what should change, such as the setting, the pose or the outfit.
- •Optionally turn on smart rewrite. The final prompt is shown on the result page, and if rewriting fails the generation stops and reserved credits are returned.
- •Choose the ratio, resolution, quality and style, then generate an image, or turn a still into a short video.
- •Compare the face and defining details against the reference before reusing the result, and find past work in the generation history.
- •Character and object library - Saves named references for people, characters and products so they can be reused across every later creation.
- •Reference-guided image generation - Uses GPT Image 2.5 with your references to place the same subject in new scenes, at resolutions up to 4K on the Max plan.
- •Image-to-video - Animates a still into a short clip with Seedance 2.0, up to 1080p and 15 seconds.
- •Smart prompt rewrite - Organizes your request into a structured prompt before generating, keeping your subjects and wording as the priority.
- •Published case studies - Shows recorded model tests with their reference images, prompts, settings, dates and limitations, rather than testimonials.
- •Product visuals - Keeps a product's shape and printed text while changing its background, for product photography and catalog images.
CharaSync suits comic and storybook creators, game and character designers, and writers who need the same fictional character to appear consistently across many scenes. Social media creators running a recurring persona or mascot can keep it on-model from post to post. E-commerce sellers and marketers can reuse one product reference to produce new backgrounds and lifestyle shots. The free plan offers 50 one-time starter credits for image generation; regular creators move to Pro, and studios that want 4K output and more credits to Max.
