Common questions
Can AI make a full video from a text prompt in 2026?
AI can make short clips from text prompts in 2026, but full long-form video still needs editing. Runway Gen-4.5, Google Veo 3.1, and Kling AI 3.0 generate realistic clips that usually run 5-30 seconds. For videos measured in minutes, HeyGen and Synthesia use avatars and scripts instead of pure text-to-video generation.
Is OpenAI Sora still available in 2026?
OpenAI discontinued the Sora consumer web app on April 26, 2026. The API is scheduled for discontinuation on September 24, 2026. Sora 2's underlying technology has been integrated into InVideo AI and Synthesia. For Sora-quality output in June 2026, compare Google Veo 3.1 and Runway Gen-4.5 first.
What is the best free AI video generator in 2026?
CapCut offers a useful free tier with access to Google Veo integration and no watermark on exports. Kling AI 3.0 provides 30 free generations per month. Synthesia offers 3 free videos per month, while HeyGen offers 1 free minute per month. Unlimited high-quality free text-to-video is not available in this comparison.
Which AI video creation tool is cheapest in 2026?
Kling AI 3.0 is the cheapest paid video generator in this comparison. It starts at $8/month and costs about $0.07 per generated second. Pika starts at $10/month, Synthesia at $18/month, and Runway Gen-4.5 at $15/month. Cost per second matters most for high-volume social video production.
