Make fewer filing decisions
Capture does not force folders, tags, or templates before the thought is saved.

Index hints
Memory for Agent
Capture becomes searchable context, not another pile of notes.
Entities, sources, and tasks stay linked inside one local index.
Agent reads structured memory; you keep the map.

Why Walnut
Knowledge work should not add more pressure.
A sustainable personal knowledge system needs to accept mess first, then offer a gentle path back to order. Walnut separates capture, indexing, and review into a calm rhythm.
Connect when context is ready
Desktop review surfaces relationships while you read and write, not as a maintenance chore.
Keep AI quiet and reversible
Entities, topics, conflicts, and links can be suggested by AI, but confirmation stays with you.
Mobile Capture
The mobile app has one job: make recording feel light.
The phone is not the full knowledge base. It is the doorway: as fast as a sticky note, as natural as a camera, and as low-pressure as a voice memo.
Text
Open and write before choosing a database, project, or template.
Voice
Record thoughts on the move, then transcribe and organize later.
Image
Screenshots, book pages, whiteboards, and receipts can enter the inbox first.
Mobile extends the desktop app; it does not compete with the desktop's deeper organizing role.
Desktop Workspace
Desktop turns fragments into a personal index.
It brings saves, notes, files, and AI summaries into one local map: what you have, how it connects, and where to go deeper.
Callable index
Sources, entities, concepts, and links stay traceable for future questions, writing, and decisions.
Know where
Walnut helps you maintain what exists, where it is, and how to call it, instead of memorizing more.
Second brain
Your notes, choices, and edits become the foundation for a personal Agent.
Gentle Intelligence
AI should reduce organizing cost, not create urgency.
Walnut's AI behavior is slow, confirmable, and reversible. It prepares suggestions; you keep the judgment.
Extract key entities
Find people, topics, projects, and timelines across text, transcripts, and OCR.
Suggest relationships
When a new capture relates to old notes, surface a light prompt instead of rewriting your library.
Bring memory back
During writing, learning, and decisions, let old knowledge reappear naturally.
Pricing
Software access and AI compute are separate.
Core capabilities stay free. Walnut currently focuses on bring-your-own-key usage, with advanced software features unlocked by subscription or lifetime access.
Secure payment is available during beta. If you are not signed in, Walnut signs you in first and then continues with the selected plan.
