Linzumi

A chat where work runs wherever it gets unblocked.

Channels your team already knows, with a fleet of coding agents running on your own machine. Talk a change through, watch the diffs land, steer every run — from your phone, your bus, your bed.

Now in beta

Watch a fleet of coding agents go to work.

See the chat in motion, then download the macOS app and take command.

Your team in the thread, your coding agents on your own machine — all in one chat.

Command your coding agents en masse and on the go.

Steer the fleet from anywhere — your phone, the bus, bed. Every run lives on your own machine and in the thread, watched and logged the whole way.

  • Every run is watched and logged — jump in to redirect mid-task.
  • Steer from your phone. No SSH, no tmux maniac mode.
  • Preview the build before you’re back at your desk.

Linzumi is your codex commander.

Your team in the thread. The fleet on the desk.

Your team steering in the thread, agents building alongside — one channel, one launch, start to ship.

One channel: your team and the agent in chat, the job on your own machine, the preview back in the thread — shipped.

What great agent work needs

Eyes on every run — and code that runs where you actually ship.

That's the whole job. Today's tools make you pick one or the other.

Your machine — but flying blind

Lonely Codex in your terminal

You start a 25-minute run, walk to lunch, come back to find it stalled at minute 3 on a yes/no question. Your teammate has no idea what's happening. Your eng lead has no idea what files it touched. The only way to redirect from the bus is to SSH from a terminal app like a maniac.

Easy to watch — but not your machine

Sandboxed agents in someone else's VM

Hosted agents solve the watch-it half by running in their own cloud. But now "works for the agent" doesn't mean "works on your laptop." You merge the PR and find the gap at 4pm.

Linzumi gives you both: your fleet on your real machine, your team in the thread, every move logged.

Outcomes

More agents. More leverage.

One operator can steer many agents in parallel — without losing the team's eyes on the work.

You ship more.

Multiple humans steer multiple AI agents in parallel, in one thread. Throughput isn't bottlenecked by any one person's attention. The team you already have does the work of a team twice the size.

You catch problems early.

Teammates jump in mid-run with “wait, do it the other way” before the agent has solidified the bad approach. Problems get caught when they're cheap to fix, not after merge.

You trust the result.

Your eng lead can let the team use AI aggressively because the diffs aren't a black box. They were watched, tried, and steered the whole way. Permissioned runtime, directory-level ACLs, full audit log of every action.

Throughput follows judgment and taste.

Each teammate steers multiple AI agents in parallel. The team you already have does the work of a team twice the size — bottlenecked by judgment and taste, not headcount.

Walkthrough

Inside a Linzumi thread.

One thread. A coding agent implements the change, posts the diff and the commands it ran, and the team reviews inline — all in the chat you already know.

A real thread — the agent ships a change, shows the diff and the tests it ran, and the team reviews without leaving chat.

C3: the channel that remembers everything.

The Continuous Context Compiler quietly turns every chat, call, and coding job into knowledge you can question — cited, current, and ready to drive the work. Nothing gets lost between the talk and the build.

Ask anything, get the receipts

“When does the iOS launch ship?” Linzumi pulls from every channel, call, and coding job, answers in plain English, and links you straight to the message it's citing.

It sits in on your calls

Paste a meeting link and Linzumi joins, transcribes live, and folds what was said into the channel — so people who missed it still catch up.

It reconciles the truth

Plans change mid-conversation. Linzumi tracks the contradictions, drops the noise, and always returns the latest answer — not a stale one.

It turns context into specs

The compiled knowledge becomes verifiable specs that drive coding work and flag issues — so what the team decided is what the agents actually build.

Trust & control

Agents work inside guardrails you set.

Every agent works inside the thread. You set what they can see. You see what they do. Linzumi never opens a backdoor to your laptop.

A live #linzumi-support channel ships with your workspace

Created on first claim, the Linzumi team on call. We can read this channel. We cannot read your other threads, your repo, your tokens, or your Codex transcripts. If anything goes wrong on first run, post there. We read it.

Agents only see what you let them see

Approve directories explicitly. The rest of your machine is invisible, period.

Tunnels close when the conversation does

Forwarded ports are scoped to the thread. End the thread, end the access. No lingering exposure.

Permissions expire with the session

Capabilities don't persist quietly in the background. Re-grant explicitly to extend.

Every action leaves evidence

Commands, files, screenshots, test output, all attached to the thread, exportable, auditable.

Sensitive boundaries gate on humans

Network egress, credential reads, repo writes, gated on explicit operator approval. Agents never escalate themselves.
