The Synthesia Alternative for Full Creative Production
Hedra is a Synthesia alternative for creative and marketing teams producing full campaigns across image, video, and voice. The Hedra agent picks the models, applies your brand, and outputs finished content from a single conversation. One workflow. Every format. On brand.
Synthesia Narrates. Hedra Ships.
Synthesia turns a script into a talking-avatar video. Hedra is the full production platform: image, video, and voice generated by an agent that learns your brand and delivers finished content in one conversation. Watch how it works.

Where Hedra Goes Further
Three areas where Hedra's approach differs from Synthesia's avatar-led workflow.
Multi-Format Output
Hedra produces image, video, and voice from the same conversation. Synthesia generates avatar-narrated video only. Everything ships from one session.
Always On-Brand
Upload reference images and the Hedra agent learns your visual style. Save logos, characters, and brand assets as Elements so your image generations, video outputs, and voice work all carry the same identity. Synthesia's brand kits apply to video only.
Beyond Stock Avatars
Omnia is Hedra's proprietary character performance model. It is audio-driven and reasons jointly over vision, text, and audio. Bring your own character from a reference image instead of picking from a stock avatar library.
How Hedra Works
Three steps from idea to finished output.
1. Describe What You Want
Open Hedra and tell the agent what you need. A product ad, a set of social assets, a campaign across formats. Upload reference images so it learns your visual style, or generate manually and choose your model.
2. Generate Across Formats
The agent selects the right models for each asset and generates images, video, and audio from one conversation. Use the prompt enhancer to refine descriptions, or let the agent handle it.
3. Refine, Save, and Export
Edit in Composer, save characters and assets as Elements for future projects, and export everything from one platform. No tool-switching. No re-uploading.
