In their own words
Castmagic
Castmagic converts long-form audio and video into transcripts and drafts such as show notes, summaries, blogs, social posts, and newsletters. Transcription supports more than 60 languages, with speaker labels, timestamps, translation, and SRT, VTT, PDF, and DOCX exports. Recurring prompts, brand voice settings, and custom prompts can generate a content set when recordings arrive. Studio creates image carousels, captioned clips in 9:16, 1:1, or 16:9 formats, and audiograms. Its content strategist answers questions across recordings, cites source moments, and drafts weekly content plans. The library connects with Zoom, Loom, Google Drive, RSS, and Zapier, and imports from YouTube, Spotify, Apple Podcasts, TikTok, Instagram, Vimeo, Twitch, Reddit, and Wistia. A REST API imports recordings and retrieves transcripts and generated content; a Claude connector can access a library. The iOS app records into a space or captures voice memos. Castmagic runs on web, iOS, and API. Plans start at $19/mo (annual), with no free plan. Listed hour allowances are 30 for Hobby, 100 for Starter, and 400 for Team.
OpenWhispr
OpenWhispr is an open-source voice-to-text assistant for dictation, transcription, and notes. Dictation works in apps that accept text, including ChatGPT, Claude, Cursor, Google Docs, Gmail, Slack, and Teams. It supports more than 100 languages with automatic language detection. For meetings, it can capture computer audio without joining a call as a bot, then create structured notes with decisions and action items. The note taker works with Zoom, Google Meet, Microsoft Teams, Slack, Discord, Webex, and other apps that play computer audio, without plugins or integrations. Audio can be processed on the device with local speech models or through OpenWhispr Cloud, which says it discards audio without retaining it. The company says user content is not used to train AI models. Free includes 2,000 transcription words per week and five meeting-recording hours per month. Pro costs $6.67/user/mo (annual). OpenWhispr runs on iOS, Linux, macOS, and Windows.
