AI brains for teams and companies.

What's in it
Documents and notesFiles, PDFs, slides, spreadsheets and notes. Search finds the passage that answers, by heading, page or table row.
Code repositoryA git repository. Search returns whole functions and classes, and Midium maps where code is defined and called from.
Linked folders
Add folders from anywhere on this Mac without moving them. They show up inside the vault and are searched with it, and members get them as subfolders. Files you drop into the vault folder still work as before. Buckets (S3, R2, B2, MinIO…) are kept as a read-only copy that follows the bucket.
Shortcuts found in this vaultSymlinks aren't followed, so these folders aren't searched yet. Link one to make it part of the vault.

Copies on members' Macs
SyncedEach member keeps a copy on their Mac. Works offline, and Finder and other apps can open the files.
Synced, encryptedEach member keeps an encrypted copy. Works offline, but only Midium can read it.
Keep on the HubNothing is stored on members' Macs. Midium reads and edits it from the Hub.
Search this vault
Finds passages by meaning, not just file names.
e.g. how many vacation days do new hires get?

A Vault is a folder Midium keeps indexed

Illustrative demo with sample data.

Agents in sync

Midium, Cursor, and Claude on one vault.

Read and write with managed permissions. Context compounds across tools instead of vanishing between sessions.

Vault MCP

Three agents reading and writing the same vault at once.

Concurrent MCP calls

  • Midium Agentwritesstandup.md
  • Cursor Agentreadsauth.ts
  • Claude AgentreadsREADME.md

  1. 1

    Write

    An agent records what it learned while it works. The note lands in the Vault, not in a chat that disappears.

  2. 2

    Retrieve

    The next call pulls that context back, on your machine or on a cluster.

  3. 3

    Continue

    The next person, or the next agent, starts from the Vault. They do not rebuild the thread from scratch.

Personal

Free, on your Mac

Midium Desktop includes one personal Vault. It stays on the device. The models and sub-agents on that machine can read it.

Shared

Shared with the team

A cluster and a Hub license add unlimited shared Vaults. Team members get scoped permissions. There is no per-seat fee. Everyone's agents read and write the same memory.

Sources

Link what you already have.

With a Hub plan, nothing has to move into one folder. A Vault can include folders from anywhere on your Mac and buckets from your cloud storage. On Free, your Vault is the one folder you put files in.

Hub plan

Included with a Hub license, alongside unlimited shared Vaults.

Linked folders

Link a project folder, a client folder, or a whole drive. It stays where it is and shows up inside the Vault. Agents search it with everything else, and edits land in the original folder.

Team members get linked folders as part of the shared Vault. Already have shortcuts in your Vault folder? Midium finds them and links each one in a click.

Cloud storage

Link a bucket, or one folder in it. The Hub keeps a read-only copy in the Vault and checks the bucket for changes. Edit files in the bucket and the Vault follows.

  • Amazon S3
  • Cloudflare R2
  • Backblaze B2
  • MinIO
  • Wasabi
  • Any S3-compatible

Access keys stay on the Hub. Team members get the files, never the keys. You see how much will be copied before anything downloads.

Like a company brain, but better

Ground a chat in several Vaults at once, or in every Vault you can reach. Ask once and the answer draws on sales, legal and engineering together. Each person still sees only the Vaults they've been granted.

Open over MCP

  • Claude Code
  • Codex
  • Your own tools

Cursor, Claude Code, Codex, and tools you run yourself use the same Vault. Local Vaults stay on your machine.
