AI agents for HeyGen
A Monmo agent works with HeyGen the way a video producer who writes would. It writes and times the script, uses the avatar, voice and template you approved, prepares training or product videos, and gets finished videos translated for other markets. It uses your own HeyGen account, asks before it spends credits on a render, and leaves any custom avatar of a real person to you and their consent.

What agents do in HeyGen
Write and time the script
From a product page or a policy document it writes the script for a two-minute video, marks pauses and emphasis, and checks the length against a normal speaking pace before any render.
AskWrite a two-minute script for the new expense policy video, in plain language, in three sections.
Make a training video from a template
It fills your HeyGen template with the script and the avatar and voice you chose, adds slides or screen recordings as backgrounds, and renders once you approve the credits.
AskMake the expense policy video with our Training template and the avatar we use for HR. Ask before rendering.
Translate a video for another market
It sends a finished video to HeyGen for translation into Japanese or Spanish, then checks the translated script against your glossary and lists the terms a native speaker should review.
AskTranslate the onboarding video into Japanese and list any product terms that need a native speaker's check.
Keep product videos current
When a feature is renamed, it finds the videos whose scripts mention it, drafts the new lines and prepares a re-render, so the help centre stops showing the old name.
AskWe renamed Projects to Workspaces. Find every HeyGen video script that mentions Projects and draft the new lines.
Personal thank-you videos, prepared for you
For a short list of key accounts it drafts a personal script for each and prepares the video. You approve each one, and sending them through Gmail or HubSpot is your call too.
AskPrepare personal thank-you videos for our five largest customers. I'll approve each before anything is sent.
Keep track of credits and renders
It keeps a list in Google Sheets of every video, its length, the credits it used and where it was published, and warns you before a month's work runs past your plan.
AskBefore we start next month's training series, tell me whether our HeyGen credits cover it.
Publish to the right place
Approved videos are prepared for YouTube, Wistia or your help centre with titles, descriptions and captions. Uploading or embedding asks first.
AskPrepare the three approved training videos for Wistia with titles and captions.
How it connects
- 1You connect your own HeyGen account once, with an API key from HeyGen's settings. Renders use that account's credits, and the agent sees only the avatars and voices that account owns or can use.
- 2You choose which agents may use HeyGen. A video editor, marketing or training-focused operations agent fits; most others do not need it.
- 3Scripts, timing and credit estimates need no approval. Every render that uses credits, every translation and any upload or share ask first. Creating a custom avatar of a real person is yours to do, with that person's consent.

Questions people ask
Can an AI agent make HeyGen videos for me?
Yes. A Monmo AI agent writes the script, fills your HeyGen template with the avatar and voice you chose, and prepares the render. Because each render uses credits, it first shows you a card with the script, length and expected credits. It works through the HeyGen connection, or in its own browser when the connection does not cover something.
Can it create an avatar of me or my staff?
Making a custom avatar of a real person is a step for you and that person, and HeyGen asks for their consent. Once an avatar exists in your account and you have approved its use, the agent can use it in the videos you ask for. It does not create one from photos or footage on its own.
How accurate are translated HeyGen videos?
It depends on the language and the script, so the agent builds in a check. It compares the translated script with your glossary and the original, and lists product names, figures and phrases that may read oddly. A native speaker should watch the result before it is published, and publishing waits for your approval either way.
Where do the finished HeyGen videos go?
They stay in your HeyGen account and are saved to the Library. From there the agent can prepare an upload to YouTube or Wistia, or a link for your help centre, with title, description and captions. Each upload or embed shows a card first, and you can decline any of them.
