Midium Desktop
Local AI on your Mac. Free.
Chat, code and create with models that run on your Mac. Your files, chats and vault stay on it.
Version 1.5.0 · macOS 26 or later · Apple Silicon
Chat, Code and Studio
Talk things through, work in a project folder, make images and video. Every model runs on your Mac, and every file change can be undone.
Your Vault
Point Midium at a folder of notes and documents. It reads them, finds answers by meaning, and grounds your chats in them.
Sub-agents for your editor
Give Cursor, Claude Code and Codex Midium's Reader, Writer and Browser, running on your Mac. One click to connect.
Fits your Mac
Works from 16 GB of memory.
Midium checks what fits before it loads a model, and steps models aside when another needs the room. More memory runs bigger models.

For teams
Turn one Mac into your team's Hub.
A Hub shares its vaults and models with everyone on your team. It all stays on hardware you own.
Shared vaults and models
Choose who can read or edit each vault. Members chat with the Hub's models from their own Macs.
Join with a link
Send an invite link. A teammate opens it in Midium and they're in, with access you can change or revoke any time.
Private by vault
Per vault, members keep a copy, keep an encrypted copy, or the files never leave the Hub.
