Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and HoverNotes when capturing code and diagrams from technical youtube lectures matters most. Run both through a week of actual calls to see which suits your workflow.

Aiko is a native transcription app for macOS, iOS, and visionOS, developed by Sindre Sorhus, that converts speech to text from meetings, lectures, and recordings entirely on-device. It uses OpenAI's Whisper model running locally, so audio never leaves the user's device, which makes it appealing for students and professionals with privacy requirements. Aiko transcribes both audio and video files in common formats such as .m4a, .wav, .mp3, .mp4, and .mov, and supports around 100 languages. Transcriptions can be exported in multiple formats, including JSON, CSV, and SRT subtitles, and the app includes a word-replacement feature to automatically correct recurring errors. It also integrates with Apple Shortcuts for automation workflows. Because Aiko prioritizes accuracy over speed, it does not perform live transcription while recording and currently does not include speaker detection, so it is best for transcribing recorded lectures, interviews, and meetings after the fact. The app is offered as a Universal Purchase with a free trial via TestFlight, making it a low-cost, privacy-first option for turning lecture and meeting recordings into searchable text. 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.
