LunaNotes vs Glasp
Both tools help you capture insights from videos, but LunaNotes keeps your notes private with AI-powered summaries and diagrams—while Glasp shares highlights publicly for social discovery.
AI-powered note-taking app with built-in video player, automatic transcription, summaries, diagrams, and flashcard generation. Private by default with team sharing options.
Glasp
Social web highlighter for PDFs, webpages, and YouTube videos. Highlights are public by default to enable discovery and knowledge sharing with the community.
Introduction
LunaNotes and Glasp both help you capture and organize insights from YouTube videos, but they serve fundamentally different purposes. Glasp positions itself as a "social highlighter"—your highlights are public by default, creating a community-driven knowledge base where users can discover what others find valuable. LunaNotes takes the opposite approach: your notes are private, with rich AI features designed to help you deeply understand and retain video content.
Glasp excels at web highlighting across PDFs, articles, and videos, with strong integrations to Notion, Obsidian, and Roam Research. It also offers unique features like building a personalized AI clone from your highlights and importing Kindle notes. However, video-specific features are limited to timestamped highlights and basic AI summaries.
LunaNotes focuses specifically on video learning with features Glasp lacks: AI-generated diagrams, interactive flashcard quizzes, semantic search across your notes, and a purpose-built video player. If you want to publicly share your learning journey, Glasp is compelling. If you want private, deep video learning with AI assistance, LunaNotes delivers more.

LunaNotes Wins for Private Video Learning
If your video notes are for personal growth, coursework, or professional development, LunaNotes protects your privacy while delivering deeper AI features. Glasp's public-by-default model means your highlights contribute to a community knowledge base—great for discovery, but not for sensitive learning. LunaNotes gives you AI diagrams, interactive flashcards, quiz mode, and semantic search that Glasp simply doesn't offer. For serious video learners who want to retain knowledge privately, LunaNotes is the clear choice.
Frequently Asked Questions
Are Glasp highlights really public by default?
Yes. Glasp was designed as a social highlighting tool where your highlights are visible to others. Private highlights require the Pro plan at $10/month. LunaNotes keeps all your notes private by default with optional sharing.
Does LunaNotes support web highlighting like Glasp?
LunaNotes focuses specifically on video content rather than general web highlighting. If you need to highlight articles and PDFs alongside videos, Glasp covers more ground. If video learning is your priority, LunaNotes offers deeper features.
Can I export Glasp highlights to LunaNotes?
Glasp exports in Markdown, HTML, CSV, and JSON formats. You can export your Glasp content and reference it alongside LunaNotes video notes, though direct import is not currently supported.

Conclusion
LunaNotes and Glasp serve different visions of learning. Glasp creates a social layer over the web—your highlights are public contributions to a collective knowledge base, and you can discover what resonates with other learners. This approach works well for exploration and serendipitous discovery, especially if you consume content across webpages, PDFs, and Kindle alongside YouTube.
LunaNotes is built for focused, private video learning. Your notes stay yours, and the AI features go beyond summarization to help you truly understand content: diagrams visualize concepts, flashcards reinforce memory, and semantic search helps you connect ideas across all your videos. The integrated video player creates a distraction-free learning environment that browser extensions can't match.
If you want to share your learning publicly and highlight across the entire web, Glasp's social model is unique. If you want private, deep video learning with AI that helps you understand and retain content, LunaNotes delivers the tools you need.
