Elai.io vs HeyGen at a glance
| Question | Elai.io | HeyGen |
|---|---|---|
| Creation | Review AI text and convert it into slides | Video Agent Chat Mode or Autopilot |
| Editing | Slide, media, recording and animation controls | Chat revisions and Edit a Copy in AI Studio |
| Learning delivery | Interactive authoring; Enterprise SCORM/Panopto | Business SCORM/LMS and interactive features |
| Branding | Team/Enterprise Brand Kit | Creator and Pro include Brand Kit |
| Connected workflows | Paid/trial video and personalization APIs | REST, CLI and MCP; API pricing separate |
Elai.io: Turn knowledge into editable presenter lessons
Elai’s features include AI-generated text that you review before converting it into slides, along with URL and presentation inputs. Screen recordings, uploaded media and animations can accompany the presenter. It supports horizontal and vertical formats; it is not limited to a static slide or a completed script.
Creator and Team provide different authoring allowances and collaboration. Creator has one user and 15 minutes/month. Team has three editors, three guests and 50 minutes/month, with Brand Kit in the comparison table. A Selfie Avatar and Voice Clone are included in the annual Team offer.
For a learning program, evaluate the interactive controls and Enterprise SCORM/Panopto delivery. Its API documentation provides paid and trial access for video/personalization workflows. Trial API access should not be treated as permanent Free access.
HeyGen: Create, revise and translate with Video Agent
HeyGen Video Agent accepts uploaded documents, images and video. Chat Mode offers plan review; Autopilot is a different creation path. You can revise through chat or edit a copy in AI Studio. It is broader than a presenter reading text.
Its July release describes HyperFrames motion graphics and website/Figma-based workflows. Avatar and translation features remain useful reasons to evaluate HeyGen, but source-based creation and planning are no longer distinctions that belong only to another tool.
Current pricing includes Brand Kit on Creator and Pro, with SCORM/LMS and interactive features listed on Business. Its developer platform covers REST, CLI and MCP operations; API pricing is separate from the web subscription.
Compare the lesson you need to maintain
For an onboarding lesson, use the same deck and learning objective. Compare the proposed structure, then ask for a shorter explanation and a changed screenshot. A creator who prefers direct slide authoring may reach a different decision from someone who wants to direct revisions through chat.
Elai Creator and HeyGen Creator are both $29/month with monthly billing. Elai includes 15 minutes/month and charges for rendered edits; HeyGen includes 600 credits with usage depending on the operation and model. Elai lists SCORM on Enterprise, while HeyGen lists learning delivery on Business.
For a presenter-led version, compare the voice and delivery using the same script and target language. Product documentation establishes features and plan access; it does not establish which avatar your audience will find most convincing.
Pricing and recurring usage
| Plan | Billing checked | Scope |
|---|---|---|
| Elai Creator | $29/month; $23/month equivalent annually | One user; 15 video minutes/month |
| Elai Team | $125/month; $100/month equivalent annually | Three editors and three guests; 50 minutes/month |

Elai charges minutes when a video renders, including edited versions of an existing project. Extra minutes are listed at $2/minute with an active paid subscription. Budget the revisions and translations you need; the annual Team avatar/voice bonus is not a monthly-plan entitlement.
HeyGen Free allows three videos/month of up to one minute. Monthly unused web credits roll over one additional cycle; annual credits follow the annual renewal terms. Model and operation determine usage, so use the current generation estimate rather than a single per-minute conversion. API allowance and pricing are separate.
ngram pricing includes 1,000 credits/month on Free. Basic costs $29/month with monthly billing and includes 3,000 credits per cycle; annual billing is $23.20/month equivalent with 36,000 credits supplied upfront. The base rate for premium AI video generation is 10 credits per second, with a cheaper model at 3. Share publicly or embed on Free; use a paid plan for MP4 downloads and Basic or above for unlisted links.
Watch a real script become a training video
The ngram example uses a script based on public NIST phishing guidance and a whiteboard treatment. Inspect its exact input, settings, transcript and result, then adapt the brief for your own lesson. It demonstrates ngram creation from a script; it is not an imported Elai.io or HeyGen project or a test of their output.
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.

Video generation uses credits. Review your estimate in ngram. MP4 downloads require Basic or higher.
How credits workBring your approved material into ngram
Start with a script, public page, uploaded PDF or PowerPoint. For existing footage, use the source tool’s download controls and your account’s export permissions to save an authorized MP4, then upload it with a brief for the new audience. Keep the original editable project and interactive course in their authoring tool.
Choose the style, aspect ratio and duration. Select your configured Brand Kit in the composer and enable captions when wanted. Approve the plan containing the script, then request revisions or use the timeline. Download the finished MP4 on a paid plan and add it to your learning platform.
After updating the original policy or document, tell ngram what changed and ask it to revise the lesson. For a different format, choose the new duration or aspect ratio and request another version. Review each result before replacing the published video.

Frequently asked questions
Does HeyGen only accept a typed script?
No. Video Agent supports documents, images and video, and current releases include website-based creation. Elai also supports documents and URLs. Test the source you actually intend to use.
Can I reuse an exported video in ngram?
Yes. Upload an authorized MP4 as source footage and describe the new audience and lesson. Keep the original editable project separately; exporting footage does not transfer its scene structure, quiz logic or review history.
Does the example compare avatar quality?
No. It is a real whiteboard lesson made in ngram from a NIST-based script. The exact prompt and result help you judge that workflow. To compare presenters, evaluate the actual script, voice and language you need in each product.
Can I share the ngram result on Free?
Free includes 1,000 credits per month and supports public sharing and website embeds. Use a paid plan for MP4 downloads; unlisted links start with Basic.
How should I choose for a learning platform?
Check whether the deliverable is a video file, a streaming course or a self-contained course package. Verify the required plan, tracking and update process with your platform. For ngram, download the MP4 on a paid plan and add it to the learning platform.
