A quiet workspace for thought
Notes, visual thinking, and relational databases. Kept in plain Markdown files on your own computer with zero cloud lock-in.
Notes that stay yours forever
Write with complete Markdown fidelity, LaTeX formulas, code syntax highlighting, and typography designed for focus. Every word is written directly into an open folder on your hard drive.
Instant bidirectional note linking
Type [[ to link any document instantly with fuzzy autocompletion across thousands of files.
Audio voice memos with local transcriptions
Dictate thoughts on the fly. Processed completely on-device without shipping audio to external clouds.
Zero-latency full-text indexing
Lightning-fast search across every note and code snippet, computed asynchronously off the UI thread.
Think across two dimensions
Map out architectures, brainstorm messy ideas, and link notes visually on an infinite 2D plane. Fully compatible with the open JSON Canvas standard.
Connect text cards, media, and directional arrows
Color-coded nodes, embedded live notes, and smart orthogonal routing for clean diagrams.
Real-time peer cursors across local networks
Whiteboard together with collaborators directly over encrypted local channels with zero lag.
Export and import without lock-in
Saved as open JSON Canvas files compatible with Obsidian, VS Code, and browser viewers.
Navigate your web of ideas
Watch relationships emerge naturally. Tomorrow calculates backlinks and page references off-thread, giving you an interactive force-directed graph of your second brain.
Filter by tags, directories, or hop distance
Drill down into specific clusters or view isolated thoughts ready for consolidation.
Smooth hardware-accelerated physics
Optimized Barnes-Hut simulation runs smoothly even across graphs with over 10,000 nodes.
Your hard drive is the database
Tomorrow does not put your thoughts into an unreadable SQLite binary blob or a remote cloud container. Your files remain genuine files.
Plain text files
Every document is standard Markdown with optional YAML frontmatter. Open and edit your thoughts in any text editor fifty years from today.
Zero account gate
No account creation, no email address capture, and zero tracking. Tomorrow launches straight into your workspace instantly.
Local network sync
Synchronize encrypted notes directly between your personal machines over local Wi-Fi without passing through third-party servers.
Experience the file engine
Write Markdown on the left, see it rendered in real time on the right, and download your note.md directly to test file interoperability.
Built differently by principle
