Synthesia
The enterprise standard for AI avatar video — corporate training at spreadsheet scale.
Synthesia built the AI video category for enterprises, and its DNA shows: templates, brand kits, SCORM exports, and a compliance story that satisfies legal departments. Thousands of companies use it to replace slide-and-voiceover training with presenter videos.
What it does well
The workflow is the product: pick a template, paste your script, choose an avatar, and export a training module — including screen recordings and quizzes — in an afternoon. Localisation into 140+ languages turns one video into a global rollout, and version updates mean re-rendering a paragraph rather than re-booking a studio.
Where it falls short
Synthesia optimises for consistency over charisma, so output reads corporate by design — fine for compliance training, flat for marketing. Custom "you" avatars and serious volume sit behind enterprise pricing, and creative flexibility trails HeyGen.
Pricing
A limited free plan exists for testing. Starter plans begin around $29/month; real deployments typically land on custom enterprise contracts.
Who should use it
HR, L&D, and internal comms teams producing structured video at scale in multiple languages.
Pros
- Polished, consistent avatars built for corporate content
- 140+ languages with one click of localisation
- Templates, screen recording, and SCORM export for L&D
- Strong compliance posture that enterprises require
Cons
- Less flexible for creative or casual content styles
- Custom avatars and scale pricing are enterprise-priced
- Delivery remains corporate-neutral — deliberate but bland
Verdict
Synthesia is what AI video looks like when procurement signs off. For structured corporate training and internal comms at scale it is the safest choice; creators wanting personality will be happier at HeyGen.
