HeyGen
You write the script. The tool delivers the video with a virtual presenter.

A teleprompter with the actor included
HeyGen is an AI video platform. You type a script — just like a text document — and it generates a video with a virtual presenter speaking every word, with lip sync, gestures, and natural intonation. Think of it as a telepresenter: no camera, no studio, no editing. The free plan allows up to 3 videos per month to try it out.
A full day of filming turned into ten minutes
Producing a traditional corporate video requires a camera, lighting, a script, recording, editing, and rendering. Any update means re-recording everything from scratch.
With HeyGen, you paste the script and receive the video. An HR professional can generate 8 distinct onboarding videos in a single afternoon, each tailored to a different department — without appearing on camera.
5 ways to use HeyGen at work
Onboarding videos for new employees. Record once — or never — and only update the script when the process changes. No re-recording needed.
Personalized video proposal sent by email. The presenter says the client's name and details the product benefits. Higher response rate than PDF.
Short video lesson with a virtual presenter for content reinforcement. Works for those who don't want or can't appear on camera.
Video in multiple languages from the same script. HeyGen translates and syncs the audio with the avatar's lips automatically.
FAQ video answering the most common customer questions. Post it on your website or send via WhatsApp. Stop repeating yourself every day.

Tips and real limitations
Do this
- Use the 3 free videos to test your actual use case before subscribing to any plan.
- Split long content into 2–3-minute modules — the AI processes them faster and viewers absorb information better.
- Punctuate your script carefully. Commas and periods affect intonation — a well-punctuated text sounds more natural.
Real limitations
- The free plan adds a visible watermark — not suitable for external presentations without upgrading.
- Advanced features like Avatar IV and lip-sync translation consume premium credits that run out quickly on the basic plan.
- AI-generated avatars have a noticeable artificial look — anyone familiar with the technology will recognize it. Best for internal use, not brand advertising.
