What they are
Castmagic
Castmagic ingests podcast episodes, video recordings, and audio files, then uses AI to produce transcripts, show notes, social posts, newsletters, and more from a single upload. Podcasters, course creators, and video producers use it to repurpose long-form content without manual editing. It covers the full repurposing workflow in one place, though the output still benefits from a human edit before publishing.
Runway
Runway is a browser-based AI video platform used by filmmakers, social media creators, and marketing teams to generate, edit, and transform video with text and image prompts. Its Gen-4 Alpha model produces short video clips from text or images, while traditional editing tools sit alongside AI features in one workspace. Output quality impresses at short durations, but longer or complex scenes still require significant iteration.
