Smart AI Assistant

Your personal expert tutor

Chat with an AI that knows your entire library of notes, PDFs, and collections. It's like having a 24/7 expert collaborator who instantly recalls everything you've ever saved.

Most research tools give you one AI model and a blank page.

Chunk gives you every model, connected notes, and a workspace that
thinks with you.

The Workflow Protocol

Three steps to go from scattered information to clear understanding.

01

Capture everything

Your research lives everywhere — PDFs in one folder, bookmarks forgotten, notes scattered across apps. Chunk brings it all together. Upload documents, save links, write notes, and run AI-powered research — everything in one place, instantly searchable.

02

Connect the dots

Great ideas get lost when your notes sit in isolation. Link them together with [[wiki links]] and Chunk maps your thinking visually — showing you how concepts relate. The more you write, the more connections you'll discover.

03

Command your research

Stop switching between tabs, docs, and tools. Group everything into a Collection and let AI work across all your sources at once — summarize findings, compare viewpoints, or answer questions using everything you've gathered.

Simple, transparent pricing.

Choose the intelligence tier that fits your workflow.
