The Problem

Your thoughts are everywhere.
Nothing compounds.

You have an idea at 7am. By 8am, it's buried in one of six apps. By noon, you're searching for something you know you wrote down — but can't find. By Friday, you're starting over.

You don't have a note-taking problem. You have a connection problem.

Capture

Capture anything in 5 seconds.

⌘Jor just say it

You see something. You remember something. You think of something. Don't organize it. Just get it in. The Brain handles the rest.

Voice

Most popular

Press ⌘J. Speak. Done. No transcription delay. Perfect for walking, driving, when your hands are full.

Screenshot

See something worth remembering? Snap it. Automatic OCR extraction so you can search for the text inside it later.

Text

Type or paste anything. A link. An email excerpt. A random 3am thought. No project, folder, or tag required.

Link

Paste any URL. Your Brain clips the content, stores the snapshot, and extracts people, dates, and topics automatically.

If capture takes longer than 5 seconds, you don't do it. You let the idea evaporate. The system that doesn't fight your friction is the system that actually gets used.

The System

Everything connects to everything.

Capture is the entry point. The real power emerges when ideas start connecting. Your Brain isn't a filing cabinet — it's a thinking tool.

Docs

Where you think

Rich text editing with structure. Headers, lists, code blocks, quotes. Link to other docs with wiki-style syntax: [[Brain]]

Slash commandsWiki linksMarkdown exportPDF export

Projects

Where work flows

Kanban boards for flow. Table views for data. Every task links to docs, other tasks, people, and the ideas that sparked them.

Kanban viewTable viewCross-linkingCustom fields

Example: You capture a voice memo about a feature idea. The Brain suggests it relates to your Q3 Planning doc. You confirm one link. Now that capture shows up in the project, your doc references the idea, and your teammate sees it assigned to them. Everything connected.

Compound Effect

Your Brain from Month 1 vs. Month 12.

The real magic isn't in the first capture. It's in the hundredth. It's in what becomes possible when months of continuous thinking live in one searchable, linked, connected place.

Month 1
47captures
8docs
3projects

Your Brain is filling up. You're still testing the workflow. You're still reaching for Notes sometimes.

Month 6
300+captures
45docs
12projects

Patterns emerge. You start a project and realize 80% of the research is already in your Brain. VERA starts suggesting connections.

Month 12
1,000+captures
120+docs
30+projects

Knowledge from Q1 informs Q3 decisions. Your Brain answers questions you didn't know you needed to ask. Your second brain is smarter than your first.

Most systems capture once. Your Brain compounds.

Privacy First

Your data. Your device. Your choice.

Your Brain lives on your device. Encrypted. Ours to protect, not to see. We can't read it. We can't sell it. We can't train models on it. That's not a feature — that's the point.

Local-First by Default

SQLite, encrypted with AES-256-CBC. Everything you capture stays on your device. The cloud is optional — you choose if, when, and how much syncs.

Owned, Not Rented

If you leave, your Brain leaves with you. Export everything as Markdown, PDF, or raw database. No lock-in. No proprietary format.

Encryption by Default

End-to-end encrypted sync via Yjs CRDT protocols. Even we can't decrypt what's on our servers. You hold the keys. Literally.

Replaces Your Stack

Stop paying for seven apps that should be one.

Notion for docs. Todoist for tasks. Granola for meeting notes. Fireflies for transcripts. Obsidian for linking. Trello for boards. Whispr for voice capture. Your Brain replaces all of it.
