Now on macOS

Full workspace. Full power. Full control.|

Semantic search, a live knowledge graph, in-note code execution, and AI chat grounded in your own files. All running locally, all yours.
The Foundation

Where your knowledge actually lives.|

Socratus for macOS gives you the full workspace, built on plain-text files from the ground up. Every note, folder, and connection lives on storage you control, not a server you can't see.

Point Socratus at iCloud Drive, Dropbox, or any folder you already use, and your workspace is exactly where you left it. No proprietary format. No account required to read your own notes.
The complete workspace, with every feature unlocked
Plain-text files you can open in any editor
Your own storage, always, never our servers
Built for Deep Work

Everything that makes Socratus powerful, with room to use it.|

Think without limits

Work across dozens of open notes at once, with multi-tab editing and keyboard-driven navigation that never breaks your flow.

Code where you write

Execute Python directly inside a note. No separate notebook, no jumping between your analysis and your ideas.

See the whole graph

Explore your entire knowledge network at once, zoomed out and readable, with every relationship scored and color-coded.

Ask your notes

AI chat answers grounded in your own documents, sources shown every time. Run it fully local or connect an external model when you need more power.

Beyond plain text

Add structured tables, run calculations, and generate charts, all without leaving the note you're already in.

Bring your agents

MCP integration turns your notes into live context for Claude, Cursor, and other agents, so they reason from material you've already vetted.
Privacy Spotlight

Powerful AI. Files that never leave your control.|

Socratus is local-first by default. Your notes stay on your Mac and in storage you choose, never routed through a server you can't audit.

For anything sensitive, file-level encryption powered by QEncrypt adds a quantum-safe layer of protection, with clear visual indicators for anything that's locked.
Local-first architecture, by default
Optional QEncrypt file encryption
Plain-text ownership, fully portable

Code, data & insights together

"I run Python right inside my notes now. Cleaning data, charting it, and writing up what it means, all in one file instead of three different apps."
James O.
Data analyst

Everything connects at a glance

"The knowledge graph is a different experience on a real screen. I can see forty related files at once and actually follow the threads between projects."
Elena V.
Product researcher

Answers grounded in my notes

"I connected Claude to my notes through MCP, and it stopped guessing. Every answer comes from something I actually wrote."
Marcus T.
Software engineer

My notes, my files, my control

"Everything stays in plain-text files on my own drive. I've moved between three note apps before. I'm not doing that again, and with Socratus I won't have to."

Technical writer
