A plugin-free note system combines Model Context Protocol support, on-device AI, an automatic knowledge graph and inline Python, with data kept under the user's control. Socratus today launched a local-first workspace designed to close the gap between storing knowledge and understanding it. The application unites AI-powered retrieval, an interactive knowledge graph and inline code execution in a single environment that runs on the user's own machine, giving knowledge workers document intelligence without moving their data to an external cloud.
The problem is common among people who rely on notes. Most applications capture information but do not connect it, leaving insight scattered across separate files and forgotten pages. Socratus treats each note as part of a connected layer that surfaces relationships automatically, retrieves answers across an entire library and keeps writing, data and AI in one place.
"Knowledge workers have faced a difficult trade-off: capable AI that sends their data to someone else's cloud, or private notes that cannot reason over their own content.", Product Manager of Socratus
This trade-off between capability and privacy is central to the rise of local-first software, private AI, and document intelligence tools for knowledge workers.
Model Context Protocol support: Agents such as Claude, Cursor and Codex can connect to edit files, restructure content and adjust the workspace through plain-language instructions.
On-device AI: Semantic search, related-note discovery and document-grounded chat run locally by default, with optional external providers available when the user enables them.
Automatic knowledge graph: Ideas are shown as an interactive, exportable network with relevance scoring, replacing static folders with visible connections between notes.
Inline Python: Code runs inside a note, keeping logic, output and written context together.
Private and portable: Notes are stored as plain-text files with local storage, optional cloud sync and file-level encryption powered by QEncrypt.
Socratus is available now and is free for personal use, with access to AI-powered discovery, graph view and plain-text storage. Commercial users can choose a one-year Professional license for $23.99 or a three-year Enterprise license for $49.99. The company reports that more than 1,000 people currently use Socratus.
The launch highlights growing demand for private AI workspaces, local-first productivity tools, and connected note-taking systems that keep data under user control while enabling AI agent workflows.
About Socratus
Socratus is a local-first workspace that helps knowledge workers capture, connect and act on information. It combines on-device AI, an automatic knowledge graph, inline code execution and Model Context Protocol support to turn static notes into a connected system while keeping data under the user's control.
