Open search from anywhere with Cmd+K on Mac or Ctrl+K on Windows and Linux (not while typing in an input). Use /w to search Word (terms and packs), /c to search Concept (bricks), and /i to search Insight (ideas, books, topics, and quests). Prefixes are strict: only /w, /c, and /i are accepted. Try /w apple, /c payoff, or /i strategy.

Insight

Reading that stays open. Ideas and sources you can return to.

All idea notes in one list. Find them fast.

Start from hard questions. Skip shallow how-to noise.

See how threads connect when reading jumps across fields.

Trace a thought back to the book it came from.

Word

Vocabulary that carries across everything you read. Look up less.

One term library for all your reading. Fewer repeat lookups.

Curated term sets and vocabularies.

Concept

Dense topics you recognize when they show up again. Visual notes, not glossary fatigue.

Heavy fields in short visual notes. Less jargon wall.
