Best free AI video generators

You don't have to pay to make AI video anymore. These tools all offer a genuinely usable free tier, daily credits or a free plan, rather than a locked trial. Hailuo and Kling give generous free credits, Pika and Luma are great for quick social clips, and Runway's free tier is a full studio to learn on. We've noted where free plans add watermarks or cap resolution so there are no surprises.
