The workspace at www-flux3.com generates 5–20 second AI videos with native audio from text or a starting image, routing across FLUX 3, MiniMax H3, Seedance, Wan 3.0 and Kling 3.0 Pro, at 720p or 1080p with video extension.
- Native audio removes the sourcing-and-syncing step that makes silent clips feel unfinished
- Five model families in one interface makes genuine comparison practical
- Draft and Enhance is the correct workflow and saves real money on iteration
- Video extension is a sensible answer to the coherence ceiling
- Generation quality is inherited from third-party models, not built here
- Model availability and terms are set upstream and can change without notice
- Twenty seconds is a hard ceiling; extensions accumulate visible drift
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
