CharaSync

CharaSync is an AI tool that lets you generate the same character or object across multiple images and videos. Instead of wrestling with prompts that produce random faces or inconsistent details, you upload reference images to lock in a person's identity, outfit, or product. The tool then uses those references to keep everything consistent scene after scene. It supports both image generation (up to 4K) and short-form video (up to 1080p and 15 seconds), so you can build a character's visual identity and then place them in different settings, lighting, or actions.

The workflow is straightforward: add reference images to a library, write a prompt describing the scene, choose settings like resolution and style, and submit the generation job. CharaSync uses GPT Image 2 for images and Seedance 2.0 for video, with internal constraints that keep the character's face, body, and clothing on-model. You can also pick from three style presets — real photo, cute cartoon, or anime — and the real photo preset applies anti-AI constraints to avoid that glossy, synthetic look. Failed generations automatically refund credits, and you can track jobs using request IDs in the history panel.

This tool is most useful for content creators who need a recurring character for social media, influencers building a virtual persona, game developers designing reference sheets, or marketers creating consistent product visuals across campaigns. The use cases page lists specific workflows like keeping the same face in AI images, generating a character reference sheet, and making consistent character videos. It's a focused tool that solves one problem well: preserving identity across AI-generated media without manual tweaking.
