Free AI video generators, and what "free" costs you
Last checked
Free AI video generation exists, but never unconditionally: the free tier of every generator pays for itself with a watermark, a resolution cap, a queue, or a small monthly credit grant. Generating video costs real money per second on someone's GPUs, so an offer with no limit at all is either a trial or a bait.
What you actually get for free
- Most generators give a monthly credit grant that buys a handful of short clips.
- Some give unlimited generation at low resolution, with a watermark.
- Several give a genuinely free first run so you can judge the output before paying.
Where it stops
- The watermark. It is the most common way a free tier pays for itself, and it is also the thing that makes the clip unusable as an ad.
- Resolution and duration. A free tier that caps you at a few seconds at 480p produces something you cannot post.
- Commercial rights. Several free tiers forbid commercial use of what you generate — which matters the moment the video sells something.
- The queue. Free generations are deprioritised, so the wait is the price.
- And the structural point: a second of generated video costs real money on a provider's hardware. Anyone offering unlimited free generation is either subsidising you to convert you later, or about to change the terms.
First paid tier: Varies by tool. The honest comparison is cost per finished video, not the headline monthly price.
And what Koda gives away
- Every new Koda account starts with 7 days of the Growth plan, and no payment card is asked for. Nothing is charged if you never come back.
- When the trial lapses the account drops to a limited free tier: 2 connected accounts, 1 generated video per day, 200 Koda Coins a month. That is a taster, not a plan — we say so rather than calling it "free forever".
- Two calculators are free with no account at all, and always will be: the ROAS calculator and the TikTok engagement rate calculator. The maths runs in your browser and nothing is sent to us.
- Koda is explicit about the mechanism rather than hiding it: generation is billed in Koda Coins, one coin is $0.001 of what the underlying provider actually charges, and a full economy video — script, image, clip, voice-over, subtitles, montage — costs about 226 coins. The free tier's 200 coins a month is roughly that many videos, and we would rather write the number down than call it unlimited.

Frequently asked
- Is there a truly free AI video generator?
- There are free tiers, but none without a condition attached — a watermark, a resolution cap, a credit grant or a queue. Generating video costs money per second on real hardware, so an unconditional free offer is a trial or a bait.
- Can I use a free AI-generated video commercially?
- Check the terms of the specific tool, because several free tiers forbid it. This is the limit people discover last and it is the one that matters if the video is selling something.
- How do I get AI video without a watermark for free?
- Usually you cannot: the watermark is how the free tier pays for itself. Tools that remove it on the free tier generally cap resolution or duration instead.
- How much does an AI video actually cost to make?
- In Koda's case a full short video — script, image, clip, voice-over, burned-in subtitles and montage — costs about 226 Koda Coins, and a coin represents $0.001 of real provider cost. So roughly 23 cents of compute per video, before anyone's margin.
