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.

Knowt is an AI-powered study platform built primarily for students and teachers that converts lectures and learning materials into organized study resources. Students can record a lecture live in the app or on the website, or upload existing audio, video, PDFs, and slide decks, and the platform's AI assistant (called Kai) generates summarized notes, flashcards, and practice quizzes from the content. Notes can be formatted as outlines or paragraphs, with adjustable detail levels, and the original audio is saved for reference. Beyond capture and transcription-driven summarization, Knowt functions as a broader study workspace, positioning itself as a free alternative to traditional flashcard apps and offering a large library of community-shared study materials. It also includes teacher-facing features for assigning material and tracking student progress. The tool spans web, iOS, and Android, making it usable across classroom, online-course, and self-study settings. Knowt is aimed at learners who want lecture capture to flow directly into reusable, exam-oriented study artifacts rather than just raw transcripts. Pricing varies by plan.
