The full list
Ranked by how well each one helps you learn from video — with an honest note on who each is actually best for.
Best for actually learning from video
What it does: A browser extension that watches the video with you in real time and generates AI notes, capturing timestamped screenshots of on-screen code, equations, and diagrams.
Best for: Students and self-learners watching courses, lectures, and coding tutorials
Pricing: Free to install; Free Starter includes 20 minutes of AI notes, then paid Pro for unlimited AI
HoverNotes is the only tool here that captures the visual frames, not just the transcript — so the diagram a professor draws or the code on a tutorial screen lands in your notes as a timestamped image. It works across YouTube, Udemy, Coursera, and 20+ platforms (plus local files), and saves everything locally to your own Obsidian vault. 4.7★ from 85 ratings, 20,000+ installs.
Best all-in-one YouTube learning assistant
What it does: Summarizes YouTube videos and documents into notes, with flashcards and an AI chat.
Best for: Learners who want a broad toolkit in one web app
Pricing: Free tier; paid plans for heavier use
The strongest generalist on this list and the most direct competitor for 'video to notes.' It's transcript-based, so it won't capture on-screen visuals, and notes live in its cloud. Great if you want one web dashboard for everything.
HoverNotes vs NoteGPTBest for quizzes and study kits
What it does: Turns uploads and links into notes, flashcards, quizzes, and an AI tutor.
Best for: Exam-prep from documents and recorded content
Pricing: Free tier; paid plans
Shines when you want testable study material generated automatically. It works from transcripts and uploads, not live video, and doesn't capture the visual frames.
HoverNotes vs MindgraspBest for flashcards and AI podcasts
What it does: Converts PDFs, YouTube links, and recorded lectures into notes, flashcards, quizzes, and two-host AI podcasts.
Best for: Students revising from PDFs and recordings (5M+ users)
Pricing: Free with capped quotas; unlimited ~$14.99–19.99/mo
Formerly TurboLearn — excellent for passive audio review and structured revision. It's an upload/record model: no live in-browser watching, no screenshot capture, cloud-based.
HoverNotes vs Turbo AIBest as an AI tutor platform
What it does: All-in-one study platform with Spark.E, a conversational tutor grounded in your uploads, plus flashcards and a Live Lecture Assistant.
Best for: Students who want a tutor to chat with about their materials
Pricing: Restrictive free tier; Base ~$4.99/mo, Premium ~$7.99/mo (annual)
More a study platform than a note-taker. Powerful if you want an AI tutor, but it transcribes rather than capturing visuals and is fully cloud-based.
HoverNotes vs StudyFetchBest for source-grounded research
What it does: Google's research tool that grounds answers in the sources you upload, with audio overviews.
Best for: Researchers synthesizing across many documents
Pricing: Free
Brilliant for asking questions across a corpus, but it's built around uploaded sources, not the live video you're watching — no screenshot capture or local vault.
HoverNotes vs NotebookLMBest for meetings (not learning)
What it does: Real-time meeting transcription with summaries and speaker labels.
Best for: Work meetings, interviews, calls
Pricing: Free tier; paid plans
The meeting-notes standard, but it's audio-first — no screenshots of code or diagrams, and it's not designed for video courses. Different job.
HoverNotes vs Otter.aiBest for fast YouTube summaries
What it does: Generates quick key-point summaries of YouTube videos from the transcript.
Best for: Skimming long YouTube videos before watching
Pricing: Free tier; paid plans
Fast and focused for YouTube TL;DRs, but it's transcript-only and YouTube-only — no visual capture, no other platforms, no local notes.
HoverNotes vs EightifyBest all-in-one note organizer
What it does: A general second brain (notebooks, tasks, web clipper) with an AI Transcribe feature for turning recordings into text.
Best for: Organizing everything in one place
Pricing: Free (50 notes, 1 device); paid Personal / Professional
AI Transcribe handles the occasional lecture recording, but it transcribes after the fact and won't capture visuals. Best if you want a general organizer, not a video tool.
HoverNotes vs EvernoteBest quick multi-source summarizer
What it does: Summarizes YouTube, PDFs, audio, and webpages into notes, transcripts, and mind maps.
Best for: Fast summaries across many content types
Pricing: Free (15 credits/mo); Pro ~$4.99/mo, Unlimited ~$8.33/mo (annual)
A versatile paste-and-summarize tool with nice mind maps. It's credit-based and transcript-driven, so no live watching or visual capture.

Questions
For learning from video, HoverNotes is purpose-built: it's the only tool that watches the video with you in real time and captures timestamped screenshots of on-screen code, equations, and diagrams, saved locally to your Obsidian vault. Tools like NoteGPT, Mindgrasp, and Turbo AI are strong transcript-based summarizers, while Otter.ai is better for meetings and NotebookLM for document research.
Most 'AI video' tools are summarizers — you paste a link or upload a file and they work from the transcript, so anything shown visually (code on screen, a diagram, an equation) is lost. A true video note taker like HoverNotes watches the actual video frames as they play and captures those visual moments as timestamped screenshots inside your notes.
Yes — most tools on this list have a free tier, though limits vary. HoverNotes is free to install and its Free Starter includes 20 minutes of AI notes plus unlimited manual notes, screenshots, and timestamps. NotebookLM is free, while tools like StudyFetch and Turbo AI have more restrictive free quotas.
HoverNotes works on any video that plays in your browser — YouTube, Udemy, Coursera, and 20+ platforms, plus local video files. Many summarizers (like Eightify) are YouTube-only, while others only accept uploads.
If the videos you learn from are full of code, diagrams, and equations, a transcript isn't enough. HoverNotes watches alongside you and keeps the visuals — saved to your own Obsidian vault.
