HeyGen and Synthesia both create videos with presenters, source material and AI planning. Consider HeyGen for its digital-twin, translation and Video Agent workflows. Consider Synthesia for its Assistant, reusable presentation formats and training-delivery options. The right choice depends on the recurring job and the plan your team needs.
Compare one actual lesson or product explanation in the workflow you would use. Review the source handling, presenter, revisions and delivery requirements. This guide also includes a real ngram training example with its exact input and a brief you can adapt.
HeyGen vs Synthesia at a glance
| Question | HeyGen | Synthesia |
|---|---|---|
| How do I start? | Instructions and uploaded media in Video Agent; avatar and translation tools | Prompt, files and URL context in Assistant; verbatim script import |
| Can I review before creation? | Chat Mode supports plan review; Autopilot offers an automated path | Editable outline before scenes are generated |
| How do I revise? | Chat changes or edit a copy in AI Studio | Chat, Storyboard and Canvas controls |
| Where does training delivery fit? | Business lists SCORM, LMS integrations and interactive video | Enterprise lists SCORM; Pro lists interactivity |
| What meters usage? | Credits vary by feature and model | Credits cover video and other generated assets |
Creation: both can work from source material
HeyGen Video Agent supports a prompt with uploaded documents, images and footage. Chat Mode lets you refine the plan before proceeding; Autopilot offers a more automated process. After generation, use chat for changes or edit a copy in AI Studio for detailed refinements.
Synthesia Assistant accepts prompts, files and URLs together. It returns an editable outline and lets you choose a template and delivery style. Continue into Storyboard or Canvas for revisions. If the exact wording is approved, use its verbatim script-import path rather than asking it to write a new script from a document.
For either product, start with the same approved material and audience. Check whether the outline preserves the important points, then request one meaningful revision. For example, ask it to shorten an introduction while keeping a safety instruction or product limitation intact.
Presenters, visuals and translation
HeyGen offers stock presenters and consent-based digital twins. Its July product update also documents HyperFrames motion graphics inside Video Agent and website-to-video creation. Treat avatar choice as one part of the video workflow, alongside the source visuals and explanation.
Synthesia combines presenters with generated visuals, motion graphics and source-driven scenes. Its video translation offering provides another path for localization. Check the language, voice, pronunciation and review controls for the material you plan to publish.
A general realism ranking cannot tell you whether a presenter suits your lesson. Review a representative paragraph, including product names and technical terms. For a localized version, have someone fluent in the target language check the message as well as the lip sync.
Training, branding and delivery
HeyGen Business lists interactive video, SCORM export and LMS integrations. Synthesia lists interactivity on Pro and SCORM export on Enterprise. Confirm the plan against the learning platform and completion reporting you need; those are different requirements from simply embedding a video.
HeyGen’s current pricing matrix includes Brand Kit on Creator and Pro, with broader team controls on Business. Synthesia’s Assistant documentation identifies Brand Kit application as Enterprise-only. Compare the actual brand and review permissions your team will use rather than assuming all paid plans share them.
Keep procurement requirements concrete: who can publish, who reviews translations, what data is uploaded and what delivery file is required. Use each vendor’s current plan and security documentation for those requirements rather than inferring compliance from a training use case.
Pricing: compare like billing terms
HeyGen pricing lists Creator at $29/month with 600 credits and Pro from $49/month with 1,000 credits on monthly web billing. Business starts at $149/month with 1,500 shared credits; additional seats cost $20/month. Web plans have rollover rules, so older no-rollover comparisons are stale.
Synthesia pricing lists Starter at $29/month with 1,250 credits and Pro at $89/month with 6,000 credits on monthly billing. Credits cover different forms of generated content. Do not treat the older minute-only plan descriptions as the current pricing model.
| Entry plan | Monthly billing | Annual-billing equivalent |
|---|---|---|
| HeyGen Creator | $29/month | $24/month, billed annually |
| Synthesia Starter | $29/month | $18/month, billed annually |
| ngram Basic | $29/month | $23.20/month, billed annually |
The table compares entry subscription prices, not equal quantities of finished video. Annual figures require an annual commitment. ngram Basic annual billing provides 36,000 credits upfront. Feature access, model choice and revisions affect what each allowance covers. Compare a realistic year of work before choosing the billing term.
ngram pricing includes 1,000 monthly credits on Free and 3,000 on Basic. The base rate for premium AI video generation is 10 credits per second; a cheaper model costs 3. Free supports public sharing and embeds. Paid plans support MP4 downloads, and unlisted links start with Basic.
Try a source-based training workflow in ngram
For a recurring lesson, ngram gives you a path from approved material to a plan and video. The example below uses a script based on public NIST phishing guidance. It shows the actual input and generated result; it is not a head-to-head test of avatar quality.
From this input to this video
A script based on NIST’s published guidance becomes a whiteboard training video with captions.
Prompt
Create a 45-second animated cybersecurity training video that teaches recognizing and reporting phishing using NIST’s small-business guidance at https://www.nist.gov/itl/smallbusinesscyber/guidance-topic/phishing to small-business employees. Use my script verbatim for the voiceover — do not rewrite it: An urgent message can make a risky click feel necessary. Phishing impersonates a trusted sender to steal information or deliver harmful software. Pause when a message asks for a password, a payment, a download or immediate action. Check the sender, and verify the request through a contact method you already trust. Do not use the message’s own link or phone number to verify it. Report suspicious messages using your organization’s process. If you already clicked, tell your security contact promptly. Pause, verify and report. Read NIST’s phishing guidance and learn your team’s reporting process. Explain the idea with the warning signs and verification steps in the NIST guidance and reinforce each key term with clear on-screen labels. Visual style: whiteboard. Tone: calm and practical. Open with a short real-world hook, walk through the concept step by step, then close on a one-line recap and this call to action: Read NIST’s phishing guidance and learn your team’s reporting process. Add captions for muted playback.
