What “AI video tool” actually covers
The label covers very different jobs. Pick by job, not by hype:
- Avatar video — a digital presenter (stock or your own likeness) reads a script. HeyGen and Synthesia.
- Voice — text-to-speech or voice cloning for narration. ElevenLabs, and built-in voices in HeyGen and Synthesia.
- Editing — cut, caption and clean up real recordings. Descript is the best-known text-based editor.
- Generative clips — short b-roll or scenes generated from prompts. HeyGen’s Pro plan lists access to third-party generation models; Synthesia lists b-roll generation that consumes credits.

A $0 AI video workflow for solopreneurs
You can produce your first month of short videos without paying anything:
- Script with a free AI chat assistant: hook (3 seconds), three value points, a niche English keyword CTA (“Comment FUNNEL / EMAIL / AI / PROMPTS”), and a disclosure line if a link is involved.
- Test avatar video on HeyGen’s free plan: 3 videos a month, one minute each — enough to see whether an avatar suits your audience.
- Test a training-style video on Synthesia’s free 10 minutes if you plan tutorials.
- Self-recorded videos remain the cheapest option: film on your phone and caption with free tools.
- Measure watch time and comments for two weeks before paying for anything.
The watermark is the main cost of staying free. For testing formats and hooks, it doesn’t matter; for your best-performing format, upgrade only that one tool.
How to choose in three questions
- Will you appear on camera? No → avatar tool (HeyGen for social, Synthesia for training) plus a voice tool. Yes → an editor such as Descript.
- What length? Under a minute, vertical → HeyGen. Several minutes, structured → Synthesia.
- How many languages? Both HeyGen (175+ on paid) and Synthesia (140+ translations on Pro) cover French and English; compare the plan that includes translation.
Common mistakes with AI video
- Paying before testing the format. Every tool here has a free tier or trial; use it to test hooks and formats first.
- Ignoring credit consumption. Both HeyGen and Synthesia now bill in credits; a longer or higher-resolution video costs more of your allowance.
- Skipping captions. Most short-form viewers watch without sound; add on-screen text.
- No call to action. End every video with one action: comment a niche English keyword (LIST, EMAIL, FUNNEL, SYSTEME, COMPARE, AI, PROMPTS), or visit one link.
Disclosure in your own videos
If you recommend any of these tools with an affiliate link, say so clearly in the video and the caption — for example “Affiliate link: I may earn a commission at no cost to you” — in line with FTC guidance in the US and Competition Bureau guidance in Canada. Also respect each platform’s branded-content settings.
Ethics and consent
Only clone a voice or likeness you own or have explicit permission to use. HeyGen and Synthesia both apply content moderation according to their pages; read each vendor’s acceptable-use policy before creating avatars of real people.
How we evaluated
We re-read heygen.com/pricing and synthesia.io/pricing on November 5, 2026. ElevenLabs and Descript figures come from our internal affiliate audit of the same day and are labelled. We did not benchmark output quality, rendering speed or lip-sync accuracy; we make no claims about them.
FAQ
What’s the best free AI video generator? For short social videos, HeyGen’s free plan (3 videos a month up to 1 minute). For longer training content, Synthesia’s free 10 minutes a month. Both are watermarked.
HeyGen or Synthesia? HeyGen for creators making short avatar clips; Synthesia for structured training and explainer videos. Synthesia’s entry plan is cheaper ($19 vs $29 monthly).
Do I need a paid voice tool? Not to start. HeyGen and Synthesia include AI voices. Add ElevenLabs if voice quality or cloning becomes central to your content.
Can I monetize videos made with AI avatars? That depends on each platform’s monetization rules and on the tool’s licence terms, which we have not reviewed for this article — check both before monetizing.
