ConceptTrail
Turn any question into a map you can learn from.
Ask what you need to understand. Get a concise map of concepts and relations, click any node for a clear explanation, and expand only the branch you need — without the AI rearranging the map.
A map, not an article
Six design decisions that keep the map useful instead of overwhelming.
See the whole picture
A small set of concepts and labelled relations, not a wall of text.
Grow one branch at a time
Click a node and expand only that idea. The AI never regenerates the whole map.
Detail on demand
Every node opens a short explanation and key points exactly when you need them.
Your map stays put
New concepts are inserted around the node you expanded; existing nodes keep their position.
First-principles structure
The map is organised around what blocks you, not a textbook table of contents.
Chinese and English
Generate and read maps in either language.
Simple, usage-based credits
Start with 16 free credits. Buy more only when you need them.
