Second Brain AI Actions
A one-click action toolbar that uses AI to maintain and grow your knowledge vault automatically.
- Daily Review — instantly creates a pre-filled daily review note (Morning Intention, Inbox Capture, Evening Reflection sections)
- Daily Capture — one-click capture note with sections for ideas, links, and quick notes
- Review Inbox — AI scans every note in 00 Inbox and suggests the right folder for each, with move operations applied in one click; shows live count badge
- Weekly Review — AI creates a GTD weekly review note, triages inbox items, and archives completed projects; shows active project badge count
- Monthly Review — AI triages Someday-Maybe list and creates a monthly reflection note; shows Someday-Maybe badge count
- Find Links — AI scans your 30 most recent notes and suggests missing bidirectional [[wikilinks]] between related notes, generating update operations
- Orphan Notes — finds notes with no incoming wikilinks, suggests which notes should point to them; shows orphan count badge
- Stale Projects — detects projects not updated in 14+ days, suggests archiving, deferring to Someday-Maybe, or adding a next action; shows stale count badge
- Knowledge Graph — AI analyses wikilink clusters and creates a map-of-content overview note in 20 Reference
- Explain Note — AI explains how your most recently updated note connects to the rest of your vault with incoming/outgoing link analysis
- Monthly Stats — AI writes a friendly stats summary: notes created, most active folder, orphan count, and 2–3 actionable improvement tips

- All actions return JSON operation blocks — apply all creates and moves in one click
- Collapsible toolbar persists state to localStorage; badge counts update in real-time
AI Knowledge Growth System
A knowledge compounding system that analyses your existing notes and grows them into an interconnected knowledge base over time.
- Scans your 40 most recent notes for recurring themes, tags, and wikilink patterns
- Identifies 3–5 knowledge gaps — concepts implied by many notes but never written as standalone atomic notes
- Creates gap-filling notes with key definitions, wikilinks back to related notes, and matching #tags
- Expands underdeveloped notes (short + no links) with new ## sections: Examples, How this works, Related concepts
- Updates existing notes to link forward to newly created notes — bidirectional linking throughout
- All operations returned as a single JSON block for one-click apply
- Works alongside the Knowledge Graph and wikilink system to build a self-reinforcing knowledge network

- Auto-syncs every 30 seconds and whenever you switch back to the browser tab
- Rename or move a note in the app and the old file is replaced automatically
- Completely separate data namespace from Local storage mode
