In plain words
CastLoom Pro is a desktop application that lets users search, download, transcribe, and archive podcasts from Apple Podcasts in one searchable knowledge base. It features local transcription via Faster-Whisper, optional translation, and exports to Markdown, JSON, or note-taking apps like Notion and Obsidian.

It runs on Windows and macOS.
