What they are
DeepSeek
DeepSeek is a large language model chatbot developed by a Chinese AI lab, available free via web, app, and API. Creators, developers, and researchers use it for writing, coding, summarization, and reasoning tasks. Its R1 reasoning model performs competitively with much more expensive alternatives, making it a credible option for budget-conscious creators. Data is processed on servers based in China, which is a real consideration for sensitive content.
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.
