The short answer
More creators choose Synthesia than Elai, and it ranks higher in our ai avatars list. Pick Synthesia if you want companies and l&d teams that need a lot of presenter-style training or explainer video in many languages, with security and approval controls. Pick Elai if you want trainers, l&d teams and educators who need presenter-style explainer and course videos from scripts or slide decks, in many languages.
Synthesia: The safest pick for business avatar video, with the widest language support, strong compliance and a usable free plan. It is built for training and internal comms, not for creators chasing social reach, and video length is capped at 3 minutes below Enterprise in the plan table.
Elai: A capable, slide-based avatar studio with useful PPTX and URL import, quizzes and one-click translation. It is built for training departments now, the free plan is a single minute, and every re-render burns minutes, so creators chasing social content will find better fits.

Strengths and weaknesses
Synthesia
- Free plan with no credit card, enough to test the editor properly
- Very wide language and voice coverage
- Strong security story (SOC 2, GDPR, ISO 42001, SSO on Enterprise)
- Consent check on personal avatars reduces misuse risk
- Videos update in place across links, embeds and your LMS
- PowerPoint and document import fits how training teams already work
- Free videos carry a watermark and cannot be downloaded
- The pricing table lists a 3-minute video length on every tier, which is short for full lessons
- Credit system makes it hard to predict how many minutes you really get
- Many headline features (1-click translation, SSO, SCORM, brand kits) are Enterprise only
- Aimed at corporate communication, so it is a weak fit for TikTok-style creator content
- No pay-per-video option
Elai
- PPTX import uses your slide notes as the script, which suits existing training decks
- Translation and voice cloning are built in rather than sold as a separate tool
- Interactivity (quizzes, branching, hotspots) is rare in avatar tools at this price
- Creator plan includes the public API
- Pricing is per minute of finished video, which is easier to budget than opaque credits
- Annual billing cuts about 20% off monthly prices
- Free plan is one minute in total: enough to test, not to use
- Every render deducts minutes, even re-rendering the same video after a small edit
- Deleting a video does not refund its minutes
- Custom avatars and voice clones are paid add-ons on Free and Creator ($199 to $500 a year)
- After you cancel, you can watch and download old videos for a year but cannot edit or re-render them
- Since the Panopto acquisition the site and features lean hard toward corporate training, not creators
- No pay-as-you-go option; top-ups need an active subscription
