01In plain English
An AI avatar is a digital person who reads your script on camera. You type or paste the words, pick a presenter, and the tool produces a video of them speaking with matching mouth movement. Some tools let you build an avatar of yourself from a short recording.
02Why it matters when you are choosing
It suits training videos, product explainers and updates that change often, because you edit the text instead of reshooting. The catch is that viewers can usually tell, so it fits some content better than others.
03What to check
Check how natural the voice and mouth movement look, how many languages it speaks, and whether you can make a custom avatar of yourself. Ask what rules apply to using someone's likeness.
04The tools
14 of the 14 tools we checked make videos with AI avatars. Each one is checked against the vendor's own pages. A tool missing from this list may not have been checked yet, which is not the same as a no.
