AI video generators and editors compared — text-to-video models like Sora and Pika, professional suites like Runway, and transcript-based editors like Descript.
AI video splits into two very different jobs. Generators (Sora, Runway, Pika) turn a text prompt into short clips — good for concepting, social content, and b-roll, but still limited in clip length and consistency. Editors (Descript, and Runway again) help you cut and assemble footage, whether it was filmed or generated. Most real workflows combine one of each. The cards below summarize where each tool fits; the full breakdown with pricing detail is in our AI video tools comparison guide. The newest entrant is Meta, whose Muse Image and Muse Video launched from Superintelligence Labs in July 2026 — free in Meta's apps, with Muse Video still in preview.

Read ReviewIt depends on the job: Sora leads on short-clip realism, Runway is built for professional editing and compositing, and Pika is the fastest route to social clips. There's no single best AI video tool for every use case — our full comparison breaks down who each is for.
Pika, Runway, and Descript all offer usable free tiers with limits on generations or export quality. Sora access is bundled into ChatGPT's paid plans in most regions.
Not yet for full productions. Generators produce short clips, so most workflows pair a generator like Sora or Pika with an editor such as Runway or Descript to assemble a finished video.
