Playground

Watch Mnemosyne think, calculate, and recall — entirely in your browser. No backend. Drag, click, mouse around.

ROI calculator

What does Mnemosyne actually save you per month? Move the sliders to your numbers and watch.

Live recall pipeline

A query enters at the left and propagates through the 7-stage pipeline. Hover any stage for what it does. Hit “Run again” to replay.

Memory graph

A live force simulation of a tiny multi-typed memory. Every dot is a typed node — fact (violet), entity (cyan), decision (amber). Mouse around.

Latency by tier

Lower bars are faster. We highlight Mnemosyne’s hot tier in violet — that’s the p50 your agent feels for already-seen queries.

Compare quality

F1 score on LongMemEval — higher is better. We didn’t pick the easiest benchmark — this is the hardest public one for agentic memory.

Try the real thing

Convinced? Take it for a spin in 60 seconds:

docker run --rm -d \
  -e DATABASE_URL=postgres://postgres:mnemo@host.docker.internal:5432/mnemo \
  -e MNEMO_KEY=mns_live_demo \
  -p 3000:3000 ghcr.io/lucasmailland/mnemosyne-server:latest
 
curl http://localhost:3000/v1/health

Then the full Quickstart walks you through writing facts and recalling them with real embeddings.
