Where we agree

Synthetic video has real, valuable use cases.

Synthesia and HeyGen built a real category. AI avatars reading a script let teams produce training, explainer, and multilingual presenter video without filming a human, and that genuinely works for the right job.

The disagreement is what counts as marketing. Synthetic-presenter video doesn't personalize per recipient with their data — it's the same avatar reading the same script. Marketing campaigns built on personalization (data, name, behavior, audience activation) are a different output and a different mechanic. We don't do AI avatars. They don't do personalized motion graphics.

When To Choose

Ditto for the personalized campaign. Synthesia or HeyGen for the explainer.

These are different tools for different jobs. Buyers compare them because they all output video, but the production models and use cases barely overlap. Match the tool to the job.

Best for the campaign moment 01/

Choose Ditto when:

Your campaign output is personalized per recipient, with data baked in
You need motion graphics with brand fidelity, not synthetic presenters
The video is the marketing — engineered to be shared by the audience
You want delivery to your audience handled, not just the video
Your brand wouldn't use an AI avatar in a flagship marketing campaign
The audience activation moment is what you're paying for, not the avatar

02/

Synthesia and HeyGen is the right call when:

You're producing training videos, explainer content, or product demos
Multilingual versions of the same script are the use case
A human-presenter look-and-feel matters and you don't want to film
Internal comms or LMS-distributed video is the goal
Per-video output is fine — no per-recipient personalization needed
Subscription pricing for steady-state production fits your team

Pricing

Different products. Different economics.

Synthesia and HeyGen sell subscriptions for steady-state video production at the per-video level. Ditto is per-campaign engagement for personalized marketing moments. The buying motions don't overlap, and shouldn't.

What's included AI avatar selection, AI voice synthesis, multilingual generation, basic editing. You write the script and produce the video. Distribution is your job.

Subscription pricing covers the avatar production. It doesn't cover personalized data-driven output, brand-fidelity motion graphics, or campaign-scale audience delivery.

What we don't do

Ditto is not a synthetic-video studio.

Synthesia and HeyGen serve real buyers Ditto isn't built for.

Ditto is not for:

AI-avatar training videos for L&D programs
Multilingual presenter explainer videos
Internal comms video where a human-on-camera substitute is the goal
Product demo video at the per-video output level
Workflows where the same script becomes many language variants

No hallucinations

Ditto doesn't use AI to produce content.

Synthesia and HeyGen lean on AI for both the avatar and the voice. At record 845,303 of a million-row campaign, you have no idea what their AI is going to do. Hallucinated copy. Wrong logo. Distorted face. Nobody finds out until the campaign ships.

Ditto's templates are deterministic. Render record 1 and record 1,000,000 with the same precision, the same brand fidelity, every time. AI-free production is why we can run campaigns at 1M+ scale and trust every output.

FAQ

Ditto vs Synthesia and HeyGen, answered.

Could I use Synthesia or HeyGen for my marketing campaign?

For some use cases, yes. If your campaign is a single multilingual explainer with a presenter, HeyGen and Synthesia are excellent. If your campaign is data-driven personalization where each recipient gets a unique video with their own information motion-graphic'd in, that's a different production model and different output, which is where Ditto fits.

Does Ditto produce avatar video?

No. Ditto's output is motion-graphics video — kinetic typography, animated layouts, brand-fidelity transitions, with personalized data baked in per recipient. We don't do AI-generated avatars or AI voice synthesis. If those are core to your job, Synthesia or HeyGen is right.

Are AI avatars a good fit for a flagship brand campaign?

Most brands say no, today. AI avatars are great for training, explainers, and internal comms where the priority is information density and language coverage. Flagship marketing where craft and brand fidelity matter usually still wants human-built motion graphics. Both opinions are reasonable; the tool that fits depends on your brand.

Can I use Synthesia or HeyGen plus Ditto?

Yes. Synthesia or HeyGen for the explainer and training layer, Ditto for the personalized campaign moments. Different layers of the production stack, different jobs.

Is Ditto cheaper than a Synthesia Enterprise contract?

For per-recipient personalized campaigns, almost always yes. For multilingual presenter video at high volume, Synthesia Enterprise is purpose-built and likely cheaper for that specific job. Compare the use cases, not the price tags.
