Your notes stay plain markdown that you and your AI assistants both read and write. Pairs with the Engram Obsidian Sync plugin to sync your whole vault.

Self-Host (Docker Compose)

Don't want to run the commands yourself? Open the Quickstart docs, select the whole page, and paste it into your AI assistant — it's written top-to-bottom as imperatives the AI can execute in order.

Otherwise:

git clone https://github.com/engram-app/Engram.git
cd Engram
cp .env.example .env       # then fill in the three secrets at the top
docker compose up -d

App at http://localhost:4000. Migrations run on boot. Only port 4000 is host-exposed; everything else stays on the private Docker network.

Large vaults? Enable MinIO for S3-style attachments: docker compose --profile s3 up -d — see storage docs.

Better embeddings? Switch to Voyage AI in .env — see embeddings docs.
