Beautiful, AI-native markdown IDE and LLM wiki

Build your personal knowledge base with Trilium Notes

Not another ChatGPT wrapper. This is a local-first tool that turns your notes, web pages, PDFs and audio/video into a personal knowledge graph — running entirely on your own machine.

The Governance Platform for Agents, Knowledge, and Context

🧠 The memory that dreams — cross-session memory for DeepSeek Harness. Local SQLite + Markdown mirrors, autoDream consolidation, 4-way recall (keyword/vector/BM25/entity), and a memory panel. 10 model tools, MCP server, CLI.

IncarnaMind is a free, open-source desktop app for macOS, Windows and Linux where you write with AI and ask questions about your own documents (PDF, Word, PowerPoint, Excel and more). It can check every sentence and figure in a draft against those documents, whoever wrote it, and every answer cites the exact page it comes from.

Self-maintaining, Obsidian-compatible knowledge base for pi — turn raw sources into an interlinked wiki that compounds. Native Open Knowledge Format (OKF) v0.2.

Local-first memory, decision engine, and governance harness for AI agents — portable across IDEs. Own the state. Rent the intelligence.

The malleable knowledge base for you and your team. Powered by Markdown and Lua.

The why layer of repo-native project memory: the reasoning behind a codebase as Markdown in the repo, versioned by Git, for coding agents and humans, so nothing rejected is proposed twice. No database, no daemon, no account.

An approachable incremental reading app.

📝 Glyph is a private desktop workspace for notes, documents, and ideas, with Markdown editing and built-in AI tools.

Your AI brain, externalized. It remembers everything you do, then becomes whatever role you need. Same skeleton can run as your chief of staff, lawyer, PM, or investigator. Plain markdown. Built on Claude Code.

🪐 Markdown with superpowers: from ideas to papers, presentations, websites, books, and knowledge bases.

The EMBL-EBI Ontology Lookup Service (OLS)

Markdown knowledge graph — LSP for your editor, CLI + MCP memory for your AI agents

A minimal, extensible, agent-native knowledge repository that keeps shared context current and inspectable
