Concept diagram
Visualize key concepts and their source sentences. No account required. Processing stays in your browser.
Use it to understand, then review
Extracted summaries retain source wording. Fill-in-the-blank questions hide a keyword in a source sentence; they do not verify facts. Concept diagrams show associations with the source, not proven causal links. Brainstorming uses prompts, not factual claims. Grouping and reading order may be imperfect in multi-column documents.
A practical example
Paste text about energy, heat and work. The diagram organizes words from the text; its connections do not prove scientific relationships.
