How Hosiqo compares and tests toolsFinal recommendation
Shortlist Castmagic when transcribing podcast episodes and generating show notes and summaries matters most, and OpenOats when privately transcribing meetings on a mac without sending audio to the cloud matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Open-source macOS meeting note-taker that transcribes calls locally and surfaces relevant talking points from your own notes in real time.
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.

OpenOats is an open-source macOS meeting note-taker, created by Yazin Akkawi (the project was previously named OpenGranola before being renamed), that sits alongside your calls and both transcribes the conversation and helps you contribute to it. It captures both sides of a meeting and transcribes audio locally on Apple Silicon so audio never leaves the device, while in real time it searches your own markdown or plain-text knowledge base to surface relevant talking points and things worth saying during the discussion. The application window is hidden from screen sharing by default, which lets it stay private during video calls, and transcripts and session logs are auto-saved locally. OpenOats supports both fully local operation through Ollama and cloud providers such as OpenRouter and Voyage AI, so users can choose between complete offline privacy and hosted models. It is written primarily in Swift, distributed under the MIT license, and actively maintained with very frequent releases. The project documents itself at openoats.com and targets users who want a privacy-respecting, self-hostable alternative to cloud meeting copilots, combining live transcription with a retrieval layer over personal notes rather than only producing an after-the-fact summary. Pricing varies by plan. Check the official website for current pricing.
