AI video tools turn a script, a prompt, or an existing video into something you can publish, often without a camera or a studio. They fall into a few groups, and the right one depends on what you make.
The main types of AI video tools
| Type | What it does | Good for |
|---|---|---|
| AI avatar presenters | Type a script; a realistic AI presenter reads it on screen | Training, onboarding, explainers, sales videos |
| Prompt-to-video makers | Describe a video; the tool assembles scenes, voiceover, and music | Social clips, ads, YouTube content |
| AI dubbing and translation | Re-voice a video in other languages, often with lip-sync | Reaching global audiences |
| Transcript-based editors | Edit video and audio by editing the text transcript | Podcasts, interviews, talking-head videos |

How to choose
- Know your output. Training modules, social clips, and translated ads need different tools.
- Check the free plan first. Most tools offer one, usually with a watermark and tight limits.
- Read how credits work. Many AI video tools now bill in credits, and minutes per credit can vary a lot.
- Confirm your languages before you pay for dubbing or translation.
