Heygen
“Avatars, dubbed in 175+ languages” — a stand-in actor who lends you a face
What is HeyGen?
HeyGen creates videos of an avatar speaking from just a script, with no one in front of a camera. It can also dub finished videos into many languages, so you can produce versions for overseas offices and customers in one pass.
- 1No camera or lighting needed; the video comes from the script alone
- 2Convert the same video into multiple language versions
- 3The free plan lets you make up to 3 videos a month, each under 1 minute
What sets it apart
These are the differences we found by running the same material through several tools in our training sessions.
No more shoot scheduling
Making one video normally means a chain of scripting, casting, filming, and editing. Here, you paste in a script, pick an avatar and a voice, and you’re done. When wording changes, you edit the script and regenerate instead of reshooting.
Other-language versions of the same video
Adapting a video made for Korea for an overseas subsidiary usually takes translation, voice actors, and re-editing. HeyGen has a feature that converts a finished video into another language, which is especially valuable for companies with many branch offices.
Consent process built into the product
To create an avatar that resembles a real person (a digital twin), you must first submit a consent video that you recorded yourself, and the avatar won’t be created if the person in the two videos isn’t the same. Creating avatars of other people or celebrities is prohibited by policy.
⚖️ The weaknesses are clear, too
Avatars work well for scenes where someone stands still and speaks clearly. They are a poor fit for acting with strong emotional swings or videos that need an on-location feel. Korean lip-sync and intonation also vary by script, so the longer the sentences and the more loanwords in the script, the more awkward it gets.
💡 In plain EnglishThink of it as a body double that carries your face and voice. Edit the script and it reshoots as many times as you like, without complaint.
Internal announcements and training videos are not “shoot once and done.” They have to be remade every time the content changes. When the cost of reshooting disappears, using video to communicate becomes a realistic option.
Same job, different approach
You need to tell every employee about safety rules that change each quarter
The old way
- Schedule a shoot date around the executives’ calendars
- Book a studio and set up the lighting
- Reshooting everything over one wrong line
- Content changes next quarter and you reshoot the whole video
With HeyGen
- Turn the updated safety rules into a script
- Choose an avatar and voice, then paste in your script
- Fix only the awkward lines and regenerate
- Next quarter, swap in only the paragraphs that changed
Common uses
Internal announcements and safety training videos
Turn guidance that changes every quarter into video. Just edit the changed paragraphs and regenerate, so updating a video takes almost no effort.
Versions for overseas branches and customers
Convert a video made for your home market into other languages and send it to your overseas subsidiaries. It lands better than subtitles alone.
Product and course introduction videos
Create a 1-minute intro video to attach to a proposal. You can also turn the script into several versions and send each client a different video.
Who it’s for
Best for
- ✓Anyone who needs to communicate frequently changing internal announcements and training by video
- ✓Organizations with overseas offices or international employees that need multilingual versions
- ✓Managers who are uncomfortable standing in front of a camera
Better served by other tools
- –Anyone making promotional videos that depend on on-location authenticity and emotional performance
- –People who only need captions or editing for footage they have already shot
- –Anyone who needs broadcast-quality Korean pronunciation and intonation

Check before you rely on it: confirm in HeyGen’s official privacy policy how uploaded data may be used for training and how to delete or withdraw an avatar.

Copy-and-paste prompts
Replace only the [bracketed] parts, then paste it in.
Turn the content below into a 1-minute internal announcement script for the avatar to read. Keep each sentence short, under 25 characters, and spell out numbers the way they are read aloud (e.g., Q3 → third quarter). Follow this order: greeting → 3 changes → effective date → contact. [Paste announcement content]
Write a script for a 2-minute welcome video to play on a new hire’s first day. Include [company name] and [department], and instead of dry policy explanations, tell them what they will do in their first week. Avoid jargon and hard-to-follow words.
When reading this script, speak a little slower and pause for a beat at each paragraph break. The words to emphasize are [word list]; read those words clearly and distinctly. Use a bright, calm tone.
Translate the Korean script below into [English/Japanese]. Don’t translate literally; make it sound natural to local employees, and spell out any abbreviations that only we use internally. Keep the length close to the original. [Paste script]
Write a 30-second script introducing [product/course name]. In the first 5 seconds, say 'who has the problem' and what it is; in the middle, give one solution; and in the last 5 seconds, close with what the viewer should do next. Avoid exaggerated claims and unsupported numbers.
Using it with other tools
Linking two or three tools changes your work more than any single tool does.
Announcement → video (one hour)
Training course → multilingual (half a day)
Before you start
- Never use a face or voice without the person’s consent. Even for employees, get written consent and agree on the scope of use and retention period first.
- Long sentences and loanwords break lip-sync and intonation. Keep each sentence short.
- Do not hide that a video uses an avatar or pass it off as real footage. If it comes out later, trust in the entire content collapses.
- Before uploading, check that no unreleased results or client names have slipped into the script. Once a video spreads, it is hard to take back.

Downsides of HeyGen
We don’t just list the positives. Here is what fell short when we used it.
- The 3 free videos run out quickly
The free plan allows 3 videos a month, up to 1 minute each. Regenerate a few times while adjusting the script’s tone and your month’s allowance is gone. You reach the payment screen before you can properly judge the quality.
- Change one sentence and you regenerate everything
Changing even one sentence in the script means regenerating the video from scratch. Unlike an editor, you cannot cut and splice just that section, so internal announcement videos whose wording changes often take a lot of work.
- Instructions are in English only
The interface and help pages are in English, so even basics like how credits are used must be read in English. In a training room where many people start at once, questions pile up from the first screen.
