What we will never build.

Editing
Descript owns this. CastMath works with the episodes it produces.
Hosting
Buzzsprout / Transistor / Captivate — we import from their APIs.
Short-form clips
Opus Clip and Submagic do this. We don't need to.
Bank connections
Architectural choice, not a technical limit. Read why.
Newsletter sending
