Async
Async is the platform formerly known as Podcastle, rebranded in January 2026. It edits video and audio through conversational prompts: removing filler and bad takes, cleaning audio with Magic Dust, generating B-roll, dubbing, lipsync and voice cloning, across Async Studio and Async API.
- The rebrand preserved accounts, projects, pricing and billing rather than breaking them
- Conversational editing is genuinely faster for coarse work and open to non-editors
- Years of speech heritage show in the audio tooling, which is where most video fails
- Studio and API let the same models serve creators and developers
- Anyone arriving from an old bookmark or tutorial is looking for a product that no longer exists by that name
- Chat is the wrong interface for frame-accurate or aesthetic edits
- A podcaster who wanted a podcast tool now owns a broader platform
Runway ML
Runway is an AI video platform built around generative world models — Gen-4.5, Aleph 2.0, and Act-Two for performance capture — split across Runway Creative for filmmakers, Runway Dev for builders, and Runway Robotics.
- Most complete AI video toolset for genuine production work
- Aleph transforms real footage, which gives far more control than pure generation
- Act-Two solves the uncanny performance problem better than prompt-driven acting
- Characters and Workflows make multi-shot sequences realistic to attempt
- Clips remain short, so longer pieces must be assembled and matched
- Control is coarse — directing a specific result takes many attempts
- Hands, on-screen text, and complex physical interaction still fail visibly
