Shortlist Castmagic when transcribing podcast episodes and generating show notes and summaries matters most, and Sotto when privacy-first transcription of imported audio recordings on-device matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Castmagic is an AI-powered content platform that transforms recorded audio and video into transcripts and a range of derived content. After a file is uploaded or imported, Castmagic transcribes it with speaker diarization and then automatically generates summaries, show notes, timestamps, titles, social media posts, newsletters, and other assets from the same recording. The platform integrates with sources including YouTube, Apple Podcasts, Google Drive, and Zoom, so recorded meetings and interviews can flow directly into a workspace for processing alongside podcast episodes. Castmagic includes semantic search across a media library, brand-voice customization, reusable templates, and commenting and approval workflows aimed at teams and agencies that manage content for multiple brands. While its marketing centers on podcasters and creators, the transcription, speaker labeling, and summary features make it applicable to meeting and interview recordings as well. It is intended for content teams, marketing agencies, podcasters, coaches, and sales organizations that want to convert recorded conversations into transcripts and repurposed written content rather than only a raw transcript. Pricing varies by plan. Check the official website for current pricing.

Sotto is a native Swift dictation app for macOS 13 and later that converts speech to text in real time. It works as a system-wide push-to-talk layer: the user holds a hotkey, speaks, and Sotto inserts clean text into whatever app is in focus, from Slack and Notion to Xcode and email fields. Audio is transcribed by local engines, including OpenAI Whisper models (Tiny through Large V3 Turbo and Distil Large V3) and NVIDIA Parakeet v2/v3, so by default recordings never leave the Mac; users can optionally connect cloud providers such as OpenAI or Groq with their own API keys for added accuracy. Beyond live dictation, it can import and re-transcribe audio files, supports 90+ languages, keeps a searchable history of recordings with timestamps, and offers a custom vocabulary dictionary. One-click AI processing can rewrite, summarize, translate, or reformat dictated text. It is aimed at developers, writers, and privacy-conscious professionals who want fast, local voice input rather than a cloud meeting-bot service.
