Turn any content into an interactive knowledge graph
YouTube videos, PDFs, audio files, articles, or raw text — Notelify automatically maps concepts and their relationships so you can see how ideas connect at a glance.
No credit card required · 15 free credits/month
What your concept graph looks like
Generated from an introductory Machine Learning lecture — 7 concepts, fully connected.
Not a diagram — a map of understanding
Auto-extracted concepts
AI identifies entities, topics, and relationships from your content — no manual tagging required.
Relationship mapping
Edges between nodes are labeled with the actual relationship: "leads to", "is a type of", "depends on", and more.
Instant overview
See the full structure of a lecture, paper, or document at a glance — before diving into the details.
Interactive & shareable
Pan, zoom, and explore the graph interactively. Share your workspace with classmates in one click.
Three steps to your knowledge graph
Submit any content
Paste a YouTube link, upload a PDF, drop an audio file, or paste raw text. All formats are supported.
AI maps the knowledge
Google Gemini reads the full content, extracts concepts, and identifies the relationships between them.
Explore the graph
An interactive concept graph appears alongside your notes, summary, and flashcards in the same workspace.
What's the difference?
Built for deep learners
Lecture comprehension
Instantly see how all topics in a lecture relate before writing a single note.
Research papers
Map out complex academic papers with dozens of interdependent concepts in seconds.
Onboarding docs
Visualize system architecture, org structure, or product concepts from internal documentation.
Science & STEM
Graph causal chains, formulas, and definitions that are hard to track in linear text.
Common questions
What is a concept graph / knowledge graph?
A concept graph (also called a knowledge graph or concept map) is a visual diagram where nodes represent key concepts and edges represent the relationships between them. It shows how ideas connect rather than listing them linearly.
How is a concept graph different from a mind map?
Mind maps radiate from a single central topic with free-form branches. Concept graphs are more structured — every edge has a labeled relationship (e.g., "is a type of", "causes", "depends on"), making the semantic connections explicit rather than just visual groupings.
Can I generate a concept graph from a YouTube video?
Yes — paste any YouTube URL and Notelify transcribes the video and maps the spoken content into a concept graph. Works especially well for lectures and educational content.
How many nodes does a typical graph have?
Typically 10–25 nodes depending on the complexity and length of the source. Dense academic papers may produce more; short articles will produce fewer.
Is the concept graph generated alongside other assets?
Yes — Notelify generates the concept graph together with a summary, notes, flashcards, and quiz in a single unified workspace. All assets are based on the same source content.
Is this a Premium feature?
Yes, concept graphs are available on the Premium plan. You can start with a free account to explore summaries, flashcards, and quizzes, then upgrade to unlock visual knowledge mapping.
