Mnemion / Free & open source

Many agents.
One memory.

Your knowledge, connected across people, apps and AI.
A shared memory that stays organised, traceable and under your control.

Free forever. For individuals and organisations.

Connected tools. Explicit access. Preserved evidence.

01 / A continuous workspace

Change tools.
Keep the context.

Useful knowledge should survive the next conversation, the next device and the next app. Mnemion gives it a shared home.

01

Memory that stays yours.

Keep decisions, facts and useful context in a workspace you control. Run the service locally or on your own infrastructure. Your apps connect to the same memory.

02

Built to work together.

Give people and agents their own access. Separate private work, projects, clients and teams into spaces, with permissions checked whenever memory is used.

03

Bring your existing knowledge.

Connect folders, Git, Google Drive and Slack. Extend to other storage through rclone or your own adapter, with checkpoints and review for incoming changes.

04

See where answers come from.

Follow citations to source evidence and revision history. Inspect connections in Studio, or keep using ordinary Markdown and the graph in Obsidian.

05

Choose how it thinks.

Start with small, local embedding models or connect an approved model endpoint. Compare a new index before switching, with controls for resources and data leaving your system.

06

Understand how it performs.

Explore memory, ingestion and resource charts. Build your own evaluation sets, compare retrieval runs and inspect the evidence behind each result.

02 / Mnemion Studio

Make yourself
at home.

A desktop home for your memory. Connect to your workspace from Windows, macOS or Linux, without installing a model on every computer.

04 / Built in the open

Know what’s here.
See what’s next.

Guides, release notes and the roadmap live alongside the code. The same documentation ships inside the app and is reviewed with every update.

Updates without the upkeep. Supported desktop installations check for stable updates automatically and restart when idle, with protection for work in progress. Workspace administrators manage service upgrades.
