Shortlist Castmagic when transcribing podcast episodes and generating show notes and summaries matters most, and HoverNotes when capturing code and diagrams from technical youtube lectures matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

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.

HoverNotes is an AI-powered note-taking tool delivered as a Chrome extension, designed for students and learners who study from recorded lectures and online course videos. Rather than relying on audio transcription alone, HoverNotes analyzes video frames as you watch, so it can capture on-screen context such as code snippets, mathematical equations, and diagrams alongside spoken content. The extension generates AI notes while you watch and saves them as plain Markdown files directly to your local file system, which makes them easy to use with tools like Obsidian or other Markdown-based knowledge bases. Users can also capture single-click screenshots embedded with clickable timestamps that jump back to the exact moment in the video. HoverNotes works across common video learning platforms including YouTube, Coursera, Udemy, LinkedIn Learning, Bilibili, and university lecture portals. It runs on a freemium model with a limited monthly allotment of AI note generation on the free plan and paid tiers for heavier use. The tool is best suited to self-directed learners studying from video, and its local-Markdown approach appeals to people who want full ownership of their notes. Pricing varies by plan. Check the official website for current pricing.
