You’ve probably seen those hyper-realistic AI avatars delivering slick corporate videos. They look expensive. They look complicated. But getting started with Synthesia? It’s actually free, and you can be up and running in under ten minutes. No credit card required. No technical headaches.
This guide walks you through exactly how to create your first free AI video using Synthesia. We’ll cover the free plan limits, a step-by-step creation process, smart workarounds for the watermarks, and a few completely free alternatives just in case Synthesia doesn’t quite fit your needs.
For a broader look at the landscape of free AI video tools, you can explore our comprehensive guide on free AI video creation software, which covers everything from cloud-based free tiers to self-hosted solutions.
Is Synthesia Really Free?
Yes, but with significant limits. Synthesia offers a Basic (free) plan that lets you explore the editor and test avatars and voices. It’s a sandbox, not a production pipeline.
Here’s exactly what the free plan includes:
- 3 minutes of AI video per month
- Export one video per month
- Watermarked exports – the logo is visible on your final video
- No credit card required to sign up
- Access to 240+ avatars across 160+ languages
The free plan is designed for testing, validation, and internal feedback. Think of it as a try-before-you-buy experience. If you need watermark-free videos, longer runtimes, or commercial rights, you’ll need to upgrade to a paid plan.
If you’re looking for a straightforward, web-based option that doesn’t require any setup, our guide on the best free AI video maker online offers additional comparisons and insights into the most user-friendly platforms.

How to Create a Free AI Video with Synthesia
Here’s the step-by-step process to generate your first AI video for free.
Step 1: Sign Up for a Free Account
Head to Synthesia’s website and click “Start free.” You can sign up using your email address or a Google account. You’ll receive a verification code in your inbox – enter it to activate your account.
No credit card is requested at any point during the sign-up process.
Step 2: Navigate to the AI Playground
Once logged in, look at the left-hand sidebar on the main dashboard. You’ll find the AI Playground option.
This is your starting point. The AI Playground lets you generate short video clips and images using text prompts. You can test multiple generative AI models in one place and compare results quickly.
Step 3: Write Your Prompt
In the prompt field, describe the video you want to generate. The more specific you are, the better the results.
Here are some prompt tips:
- Scene and action focus – What’s happening in the frame?
- Visual realism – Cinematic, photorealistic, naturalistic, stylized
- Camera behavior – Static shot, slow pan, smooth tracking
- Environment detail – Interior or exterior, time of day, weather
- Restrictions – Simple background, no quick cuts, no exaggerated movement
Quick tip: Come in with one script ready (100–150 words). You’ll get better results than tinkering without a plan.
Step 4: Select Veo 3 Model
Before generating, make sure you select a Veo 3 model. Currently you can choose between Veo 3.1 and Veo 3.1 Fast.
Which one should you use?
- Veo 3.1 – Use when you need the best visual quality, stable motion, and cinematic detail for final clips
- Veo 3.1 Fast – Use when you want quick iterations, prompt testing, or early concepts where speed matters more than visual detail
You can also change the aspect ratio to 16:9 (landscape) or 9:16 (portrait).
Step 5: Generate Your Video
Submit your prompt and wait. Generation takes a few moments. While you wait, you can explore pre-generated visuals in the AI Playground or browse other areas of the Synthesia platform.
Step 6: Preview, Download, or Share
Once your clip is ready, you can:
- Preview the full video
- Share it with a link or invite collaborators
- Download the clip in your preferred format
- Reuse the prompt and adjust it for different output
Remember: free exports come with a watermark. Don’t try to crop or blur around it – it looks bad and defeats the purpose.
Step 7: Build a Complete Video in the Editor
To turn your Veo 3 clip into a complete video, click “Continue in editor”.
The editor lets you:
- Add realistic AI avatars and natural-sounding voiceovers
- Include interactive elements like quizzes and CTAs
- Auto-sync script timing with narration
- Localize content with AI translation
- Apply brand controls (colors, fonts, logos)

Frequently Asked Questions
Can I use Synthesia completely free forever?
No. Synthesia’s free Basic plan gives you 3 minutes of video per month and one watermarked export. It’s designed for testing, not ongoing production. For watermark-free videos, you’ll need a paid plan.
Does Synthesia require a credit card for the free trial?
No. You can sign up for the Synthesia free plan without entering a credit card. The free plan has no payment obligations. You only pay when you choose to upgrade to a paid tier.
What is the difference between Veo 3.1 and Veo 3.1 Fast?
Veo 3.1 prioritizes visual quality, stable motion, and cinematic detail – use it for final clips. Veo 3.1 Fast prioritizes speed – use it for quick iterations and prompt testing.
Is there a completely free alternative to Synthesia without watermarks?
Yes. Agnes Video Generator is completely free, open-source, and has no watermarks or usage limits. However, you need to download and run it locally. For a fully online option, FreeShortVideoStudio runs in your browser with no install required.
Can I remove the watermark on Synthesia’s free plan?
No. The watermark is a deliberate part of the free plan. You remove it by upgrading to a paid plan. Attempting to crop or blur it looks unprofessional and violates the service terms.
