Penlog

Converts handwritten journal photos into a searchable, AI-powered local knowledge base using Tesseract OCR. It enables users to query their notes, track insights, and export data through MCP-compatible AI assistants while maintaining complete local data privacy.

MCP server enabling AI agents to read and append to a user's daily bullet notebook, with entity-graph tagging and append-only, auditable notes.

Enables an AI agent over MCP to read, file, and correct a plain-file, self-hosted personal life store — memories, people, money, body, papers, decisions and someday, alongside the usual tasks, projects, goals, habits and areas — recording every edit and deliberate non-edit so it can be reviewed and reversed. The agent does the maintenance work; the user just visits to glance at what needs them or wander through what's there.

Enables AI agents like Claude Code and Codex to read handwriting and sketches drawn on a tablet in real time via MCP, with local recognition to text/LaTeX, session recording, and export to Markdown/Excalidraw.
