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.

Polar Notes (PolarNotes AI) is an AI note-taking tool built for students and teachers that converts lectures and course materials into organized study resources. Users can record or upload a lecture, paste a YouTube link, or import slides and PDFs, and the app automatically transcribes audio when needed and analyzes the content to produce summarized notes, key concepts, section headings, and short overviews. From the same source material it can generate a study pack that includes study guides, flashcards, and assessment questions, and results can be exported to Google Docs or PDF with study sets organized in one place. Polar Notes emphasizes privacy and offline access on iOS, keeping notes stored locally on the device unless the user chooses to back them up or share them, which lets students review notes without an internet connection. It also supports multilingual transcription, making it usable for international students and teachers recording in different languages. The tool is delivered as an iOS app with an accompanying web experience and free online tools, and is aimed at learners who want lecture and document content distilled into exam-ready study material rather than verbatim meeting records. Pricing varies by plan. Check the official website for current pricing.
