Most AI video tools either stamp a watermark on your clip or put you on a monthly plan before you have made anything worth keeping. Sisif does neither. Describe the scene, pay for that one clip, and post the result to TikTok, Reels, Shorts, an ad or a product page a few minutes later.

Questions
Is Sisif free?
No. Sisif has no free tier and no free trial credits. A new account starts with 0 credits. Signing up, using prompt suggestions, and planning a storyboard are free. You can plan 3 storyboards in 24 hours before you have paid for a clip or a plan, and 10 in 24 hours after. Rendering a video costs $1 per 5-second clip, paid once.
Is there a free AI video generator with no watermark?
Sisif is not a free generator, and it never adds a watermark. There is no watermarked free version. The $1 clip downloads as a clean MP4.
What do I get for $1?
One 5-second clip at 540x960, with no watermark, paid once, and no subscription. The credits do not expire. Buyers in the EU, EEA, and the UK see VAT added at checkout. A story costs $1 per 5 seconds of the length you choose, up to 60 seconds, and you see that price before you pay.
What happens if a render fails?
The credits return to your account automatically, so you can try another prompt.
Do I need a subscription?
No. Pay per clip. Monthly plans exist for people who render every day, but nothing forces you onto one.
Can I see what I'll get before paying?
For a longer brief, yes. Sisif shows a storyboard of the planned shots and the price before you pay. A single short clip is not shown as video before you buy it. Prompt suggestions and the example clips on this page are free to use.
