AI video generation from text and image. Free for casual creators.
Haiper is the AI video generator from the ex-Stability AI team (the same crew behind Stable Video Diffusion). It launched in 2024 and quietly became the best free AI video tool in 2026 — 10 free 4-second videos per day is more than Runway, Pika, and Kling combined.
Who it's for: Casual creators who want to try AI video without a credit card. Hobbyists making TikTok content. Anyone who wants a runway alternative that doesn't charge per generation.
Type a prompt, get a 4-second video clip. Up to 1080p output on the Pro plan. Solid prompt adherence — handles motion, camera movement, and lighting cues reasonably well.
Upload a still image and Haiper animates it. Great for bringing product photos and concept art to life. The image-to-video pipeline is faster than Sora's.
Change the style of an existing video clip — turn daytime footage into nighttime, pencil sketch into oil painting. This is Haiper's unique superpower that nobody else has matched well.
10 free 4-second videos per day at 720p. Way more than competitors like Runway or Pika give away. Enough for casual content creators who don't want to pay.
If you want to try AI video without paying, Haiper's free tier is the best in 2026. 10 videos a day is enough for a week of TikTok content. Upgrade to Pro when you need longer clips or higher resolution. Power users should still pay for Sora or Runway for serious work.
