What it does
Mindolph is an open-source desktop personal knowledge management application. It stores files in local workspaces, organizes them in a tree, and supports Markdown, mind-map, PlantUML, CSV, and plain-text formats. Its official site describes AI assistance for generating or summarizing text through an LLM provider API, along with multiple tabs, collections, outlines, and reusable snippets.
Keep a project workspace file-based
Use a workspace for a subject or project, then organize Markdown notes, mind maps, PlantUML diagrams, CSV sheets, and plain-text files in its tree. Mindolph's product site describes local storage and collections for related files, including files from different workspaces; the repository adds details about multiple tabs, outlines, and snippets. This is useful if a knowledge base needs diagram and data files alongside prose rather than a single proprietary note format.
Mindolph also describes generating or summarizing content through an LLM provider API. That dependency means the AI feature should be assessed separately from the local note store; the provider list, API setup, cost, and privacy terms were not verified here. The official releases page listed v1.14.7 as the latest release checked on 2026-10-25. No installation or LLM connection was tested.

- Workspaces store files locally and organize them in a tree instead of locking notes into a single cloud service.
- Supports Markdown, mind maps, PlantUML, CSV, and plain text in one desktop environment.
