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.

Whisper Notes is an offline speech-to-text application for Mac and iPhone that records and transcribes meetings, lectures, and voice memos entirely on the device. It is built on OpenAI's Whisper speech recognition, with model options including Whisper Large V3 Turbo on Mac, Parakeet on iPhone, and SenseVoice for Asian languages, and it supports transcription across 100-plus languages. On Mac, the app can automatically detect when a meeting starts on platforms such as Microsoft Teams, Google Meet, and Zoom, then record and transcribe it locally without sending a bot into the call. Because processing is fully offline, the company states that data physically never leaves the device and that privacy is architectural rather than a policy promise. Additional Mac capabilities include auto-generated summaries and titles, on-device AI chat with longer transcripts, streaming transcription output, and system-wide dictation via the function key. Users can also import existing MP3, M4A, and WAV files for transcription and export results with timestamps. The product is sold as a one-time purchase per platform rather than a subscription. Pricing varies by plan. Check the official website for current pricing.
