LightNote

Lightweight code and notes editor for Windows·lightnote.com.br

LightNote is a lightweight native (C++20/Qt 6, non-Electron) editor for Windows that combines Markdown-based personal knowledge management with a cockpit for local AI coding agents. It supports wikilinks, backlinks, a connections graph, daily notes, Kanban/Gantt task boards, an integrated code editor with an AI terminal, inline AI editing with diffs, and an MCP server/CLI to expose the workspace to AI agents. It also opens Parquet/CSV/JSON/Excel as queryable tables via DuckDB, connects to SQL databases, and supports SSH/SFTP sessions, all running 100% locally with data stored on the user's own disk.
