bloks

Bloks is a desktop app for personal AI agents. It looks like a messaging app: each agent is a contact you talk to, each room is a group chat, and all of it runs on your own computer. The agents work next to your files, on engines and keys you already have, and stop to ask before doing anything that needs your say-so. No account to make, and no server of ours holding your data.

Underneath, every agent is a real engine session: Claude Code, Codex, Gemini CLI and the others that run tools, or any API you hold a key for. Agents stream their replies, show you what they are running, and keep what they learn in plain files you can read and edit.

The iPhone app pairs with the desktop app. Nothing runs on the phone: it is a window onto the agents on your computer, with approvals you answer from the Lock Screen or your wrist.

📣 Bloks 3 is out

Bloks 3 is out for Mac, Windows and Linux, and on the App Store for iPhone and Apple Watch. An Android app is coming soon.

Thank you to everyone who reported a bug, tested a build or sent code for this release. A lot of what is in it started as one of your issues, and it is a better app for every one of them.

New in 3.0

Workspaces. Personal, Business, or one with a name of its own, each a whole Bloks with its own agents, memory, keys and rooms, a mark you choose, and a switcher at the top of the window to move between them. One plan and one Bloks key cover them all.

People. On Bloks Team, invite someone into a workspace with a code, a QR or a link, read the same four words, and they talk to your agents beside you, with the access and the spending limits you choose.

Usage. See what every agent spent, by agent and by engine, and put a monthly limit on any engine that runs on your own API key.

Your phone. Pairing starts when you ask for a code, and with the iPhone and Apple Watch update the phone finds your Mac again when its address or port changes, adds your other workspaces in a tap, draws answers natively, and shows an agent's browser or cloud computer live, for you to watch or take over.

Plus answers drawn as cards, tables and charts, a terminal that goes anywhere in the window, side lists that resize and fold, a window that comes back on its own if it fails, a Plan page, Settings rebuilt around one search, and a new shape for the whole app. Everything is in the 3.0 release notes.

A tour

Workspaces

A workspace is a whole Bloks of its own: its own agents, memory, keys, rooms, routines and settings, in its own folder. Nothing moves between them, so the agents that run your company never read your family's notes. Personal is the Bloks you already had. Add a Business workspace, or one with a name of its own, and it opens on a short welcome shaped by what you picked. Each wears a mark that nobody else on your computer wears: choose a colour and a pattern for any of yours, from the computer or the phone, or upload your logo. On a workspace you joined, the mark you pick is yours alone.

The switcher at the top of the window lists them in the order you drag them into, with a dot where something is waiting; Cmd+1 to Cmd+9 jump straight to one. Every workspace keeps running while you look at another, so routines and watchers carry on, and an approval in the background still reaches you. Each can be muted for a while, and each says how much it may interrupt you: everything, only what needs you, or nothing.

With Bloks Cloud, each workspace can also be reachable online on its own switch, for your phone and the people you invite.

Workspaces on servers you run sit in the same switcher. Pair as many bloks-servers as you like from Settings, Phone and devices, Your servers (or Add a server in the switcher), name each, and switch with Cmd or Ctrl and a number. Each keeps its own pairing, so adding, pairing again or removing one never touches another, and one that can't be reached leaves the rest working. Turn off Run workspaces on this computer there and the app is only a window onto your servers: it starts no workspace and runs no agents of its own, and the ones on the computer wait, untouched, until you turn it back on.

Bring people in

Invite a partner, a colleague or a client into a workspace. An invite is a QR code, an 8 character code you can read out (K7QF-M2XR) and a link that shows as an invite card in Messages, Slack or WhatsApp. It is for one person, works once and lasts a day. They join from the iPhone app or the desktop app, and before they are in, you both read the same four words, so somebody who intercepted the link is stopped at the door. A join password, checked only on your computer, can sit behind it too.

What they get is decided by you:

• Roles. You are the owner. Admins invite and manage people and look after every agent's settings with you; members use the agents, rooms and memory.
• Team agents. Each agent has one shared team conversation, and you choose who is in it: everyone, only some people, or everyone except a few. Rooms are chosen the same way, one by one.
• Private one to ones. Anyone who can reach an agent can also talk to it privately. Nobody else reads that, unless you turn on reading members' private conversations, and members are told which way it is. What the agent remembers there is kept for that person alone, apart from its memory everywhere else, and when it looks back it finds only what that person could already read. Your own conversations, search and recall never reach a member's private words either.
• Their own apps and keys. Each member connects their own mail, calendar and other apps (with a Composio key of their own) and saves their own keys, under Your connections in their app. Their private conversations and solo agents use them, so "pull my email" means the inbox of whoever asked; a room, a team conversation, you and everyone else never do. Your own apps and keys stay yours the same way, and so does the rest of you: your profile, your shared memory, and what the engines on your computer are signed in to as you (the Gmail and Calendar of your claude.ai sign-in, the tool servers in your own Claude Code and Codex settings) never reach a member's turn or a member's own agent, so their agents never take your accounts for theirs.
• A welcome of their own. Someone who joins is shown, once, who they are signed in as, what is shared and what is theirs, and where to tell agents about themselves, connect their apps or make their own agent. A household works the same way: make a workspace for it beside Personal, invite the family, and each of them keeps their own.
• On your behalf. In a team conversation or a room, you or an admin can ask an agent to message someone ("message Sam about the draft"), and it writes in Sam's private conversation, marked as sent for you.
• Solo agents. Members can make agents of their own, private to them, on the engines you allow, and change them from the agent's menu: name, instructions, engine and model, how it asks, its own browser. Letting one act without asking, or giving it a computer, stays yours and your admins', and the setting says s
