Backlinks

Every note knows who mentions it.

A backlinks panel sits under every note, listing each place the idea appears — the lecture, the reading, the 2 a.m. thought. Open a note from months ago and instantly see everything that’s built on it since.

Knowledge graph

Your whole semester, drawn as a map.

Graph View turns every link between your notes into a picture you can wander. Watch clusters form around topics, spot the gaps, and find the note you forgot you wrote.

Maps of Content

Notes that organize themselves.

As your library grows, clusters of connected ideas form on their own. Chunk spots them — and one click writes a Map of Content: a table of contents for your thinking, organized by how tightly the ideas connect.

The experiment basically demonstrated that, in a way, particles can kind of influence each other instantly across really big distances — which Einstein hated.

✂️ concise

“particles influence each other instantly at any distance”

AI writing tools

Select text. Fix it in place.

Highlight any sentence and a small toolbar appears — tighten it, expand it, fix the grammar, shift the tone, or translate it. No copy-pasting into a chat window. Whole-note tools handle the big jobs, powered by the same multi-model AI as Chunk’s chat.
