AI video generator for commercial use: what the terms allow

Yes, you can use an AI video generator for commercial use, but what is allowed is set by each tool's terms and plan, not by the model. HeyGen limits its Free plan to non-commercial use, Kling describes its free plan for personal, non-commercial use, Synthesia bars stock avatars from paid promotion, and on Sume the terms say Sume doesn't claim ownership of generated outputs and paid plans include commercial use.

Each row below quotes that company's own terms or help pages, read on 2026-09-28; Sume's comes from its Terms of Service and pricing page. It reports what the terms say. It is not legal advice, and it doesn't answer who owns AI output under copyright law.

Which AI video generators allow commercial use?

Rows are alphabetical, not ranked. Read the terms for your plan before you publish:

Can I use a free plan's videos commercially?

Not always. HeyGen's terms give Free-plan users a license to their output only for personal, non-commercial and internal evaluation purposes, and say it may not be sold, monetized or used in advertising or client work. Kling describes its free Basic plan for personal, non-commercial use and lists commercial use on its paid plans.

Sume's terms say paid plans include commercial use as described on the pricing page, and its pricing FAQ lists commercial use among what paid plans add. Check the pricing page for the plan you are on.

What else should I check before I publish?

A plan that allows commercial use is only the first check:

• Stock assets. Synthesia's stock and synthetic avatars and voices may not be used in paid TV, Facebook, Instagram, YouTube, TikTok or programmatic ads, or any other paid promotion.
• Your inputs. Sume's terms require the rights to what you submit, including permission to use any person's likeness or voice; Higgsfield's and HeyGen's terms make the same kind of representation part of use.
• Disclosure. HeyGen's terms require you to disclose AI creation where the law requires it, and Sume's acceptable use bars misleading people about the origin of generated media.
• Review. Sume's terms make you responsible for reviewing outputs before publication, distribution or commercial use, and call generated outputs synthetic and possibly inaccurate.

How does commercial use work on Sume?

The same terms cover everything generated for your account across Sume's agent, Formats and model APIs, video or not: Sume doesn't claim ownership of the outputs, and you keep ownership of what you submit (prompts, scripts, product images, voice input, likenesses, brand assets). You grant Sume the rights it needs to run the service on that content.

If you work from a talking avatar of a real person, have their consent for their likeness and voice before you create it. How Sume's avatar and generation plans compare with each vendor above is in the comparison posts, for example Sume vs HeyGen and Sume vs Synthesia.
