A note-taking system where every idea connects. Wiki links, a living knowledge graph, and AI that writes with you — not for you.
Quantum entanglement occurs when two particles become correlated in such a way that the state of one instantly influences the other.
This connects to [[Bell's Theorem]] and the work described in [[EPR Paradox Notes]].
Quantum entanglement links two particles so that measuring one instantly determines the other's state.
The basis of modern AI relies heavily on core architectures such as [[Neural Networks]]. Optimization is typically achieved via methods like [[Gradient Descent]], which iteratively minimizes the loss function.

[[ and your ideas start talking to each other.Every note in Chunk can reference any other note using wiki link syntax. Type `[[` and an autocomplete dropdown appears — search your entire library of notes by title, select one, and the link is live.
Links are bidirectional. When Note A links to Note B, Note B automatically knows about it. A backlinks panel below every note shows you every note that references the one you're reading.
Rename a note? Every wiki link pointing to it updates automatically across your entire library. Zero broken links, zero maintenance.
Your notes aren't a list — they're a web of ideas. Graph View turns every link between your notes into a visual map you can explore, click into, and discover connections you never noticed.
As your notes grow, clusters emerge — groups of tightly connected ideas that form around topics. Chunk detects these clusters automatically.
With one click, the MOC Generator creates a Map of Content note — a structured index of the largest cluster in your graph, organized by connection depth. It's an automatically generated table of contents for your thinking.
Use MOCs as launchpads. Open one and navigate into any branch of connected ideas. It's how researchers and students turn hundreds of scattered notes into navigable knowledge.
Chunk's AI writing tools work inline — select any text and an AI toolbar appears. Make it concise, expand it, add citations, fix grammar, change the tone. No copy-pasting into a separate chat window.
Full-note tools cover broader operations: summarize the entire note, translate it, check grammar globally, adjust the overall tone from academic to conversational.
Powered by the same multi-model AI system as Chunk's chat — your notes get the benefit of GPT-5.4, Claude, and Gemini without leaving the editor.
Add any note to a Collection as a live reference — edits you make to the note are instantly reflected in the collection. No stale copies, no sync issues.
When you add a note, Chunk checks for backlinks and suggests adding connected notes too. One click to pull in an entire web of related thinking.
Toggle notes on or off in the Collection's context window. Ask AI questions across your notes, documents, URLs, and research reports — all at once.
And nothing they don't.
