What is the Synthesia Assistant?
The Synthesia Assistant is a chat-based AI built directly into Synthesia that helps you create and refine videos from start to finish. Because it’s agentic, the Assistant doesn’t just suggest improvements — it can take action inside your video, updating scripts and visuals for you in real time.
It can:
Turn a prompt (and supporting files) into a complete first draft
Write and improve your script
Create and update visuals
Suggest ways to make your video more engaging
Instead of generating a video in one attempt, the Assistant works with you through iteration — so you can refine your video step by step inside the Editor.
How to create a video with the Synthesia Assistant
Click Start with Assistant.
In the prompt field, clearly describe the video you want to create. Include:
The topic
The target audience
The objective or goal
Select a Template and Length of the video.
If required, (Optional) Upload supporting materials:
PDFs
PowerPoint files
Word documents
URLs
Multiple files at once
Click Create video.
💡 Example of a strong prompt:
"Create an onboarding video for new product managers at a fintech company. The goal is to explain our product development lifecycle and key collaboration tools. Keep the tone professional but friendly."
The more relevant context you provide, the stronger your first draft will be.
Reviewing and refining your video with Assistant
After clicking Create video, you’ll enter the Storyboard layout.
✍️ Storyboard is a macro-level view of your video where you can see:
Script on the left
Scene visuals in the center
The Assistant chat panel on the right
This layout allows you to review and refine your entire video in one place.
Use the Assistant chat panel to iterate on your video. You can ask it to:
Make the video shorter
Adjust the tone (e.g., “Make this more executive”)
Improve engagement
Rewrite specific scenes
Change visuals
Suggest improvements
The Assistant can:
Create and revise scripts
Update visuals
Generate relevant images
Provide feedback on how to improve your video
💡 If you prefer scene-level editing, click Collapse in Storyboard to return to the traditional canvas view. You can switch between Storyboard and canvas at any time.
Need to import a script verbatim?
If you already have a finalized script and want the Assistant to use it without rewriting:
Click Start with Assistant.
Open the script import flow.
Paste your script or upload your file.
Click Create video.
The Assistant will respect your script verbatim, keeping your wording unchanged while building the visuals around it. This is especially useful if your script has already been approved or must remain exactly as written.
