I built a local-first AI memory layer for LLMs in Rust (no cloud, no API keys)
Every LLM app has the same problem — the model forgets everything between
conversations. Cloud solutions like Mem0 exist but they send your data
to their servers. I built mnemo to solve this locally.
What it does
mnemo runs as a sidecar process next to your app. You POST text to it,
it extracts named entities and relationships using a local LLM (Ollama),
builds a persistent knowledge graph, and injects relevant context back
into your prompts automatically.
The stack
● Rust — core engine, 4 crates (mnemo-core, mnemo-api, mnemo-cli, mnemo-bench)
● SQLite + WAL mode — persistent storage, survives restarts
● petgraph — in-memory knowledge graph with BFS traversal
● Axum — REST API sidecar any app can call
● Ollama — fully local LLM, zero API costs
Fully free by default
Works with OpenAI or Anthropic too if you bring your own key.
Python SDK
Numbers
● 122 Rust tests, 21 Python SDK tests
● Sub-millisecond entity lookup
● ~4ms full retrieval pipeline (debug build)
Links
GitHub: https://github.com/zaydmulani09/mnemo
Would love feedback, especially on the retrieval scoring and graph
traversal approach.

I built a Rust CLI because I kept forgetting to open my todo app
I always wanted to organize my tasks in a todo app, but because the habit was new, the next day i would always forget the existence of it. So i built something that opens itself (or, well, whenever your terminal does, by default)
Meet Amnosia. The CLI Tool that opens whenever your terminal does.
It's different from a regular todo app, because it gets in your face (in a good way!)

To install, you can just clone the repo on github and then use cargo to put it in your PATH.

adding reminders, seeing them, and deleting them, is as easy as three commands:
