Overview
What Mnema is
Mnema is a desktop application for personal documentation: a place to write, connect and revisit knowledge. It pairs a markdown editor with a graph of the links between documents, rendered both as a 2D map and as a navigable 3D space, and adds an LLM layer and versioning on top.
The name comes from ancient Greek μνῆμα (mnêma) — a memorial, that which is remembered. The app is built around that idea: not just storing notes, but keeping the relationships between them visible and alive.
Features
What it does
2D & 3D link graph
See the connections between documents as an interactive graph — Cytoscape.js for 2D, a force-directed Three.js scene for 3D.
LLM integration
Local models via Ollama, plus external providers: Anthropic, OpenAI, Google and any OpenAI-compatible endpoint.
Local-first storage
Everything lives in a local SQLite database with a custom incremental migration system.
PDF extraction
Pulls text out of PDFs with the Rust pdf-extract crate, silencing its ligature noise.
Versioning
Document history is tracked, so you can see how a note evolved over time.
