Graph-first AI workspace for AEC

Drafted, not generated.

One canvas wires the tools you already use: Revit, Excel, PowerPoint, Word. The AI edits the graph; you approve the line. Your work stays local. Your knowledge stays yours.

The three pillars

Canvas. Composer. Brain.

The whole product is three ideas, and not one of them is a chat box.

01The surface

Canvas

Every action is a node; every node is replayable. Drag a parameter and the chain downstream re-runs. Nothing happens that you can't see, trace, or undo.

02The hand

Composer

Talk to the project. The AI proposes edits to the graph; you approve the line before it's drawn. Set out, don't ask out: review is the default, not an afterthought.

03The memory

Brain

Persistent memory and reusable skills that grow with your firm. Save any thread as a skill: a graph-held assembly you own, with the work it was learned from and the evidence that earned it. No marketplace lock-in.

Self-healing connectors

Self-healing connectors

Your CAD tells us when it breaks. We listen.

No restarts. No "please relaunch Revit." The connector watches the host, reconnects on its own, and tells you what it did.

illustrationYou didn't notice. That's the point.
Every step is a node

The canvas

A graph you can audit, not a transcript you have to trust.

  • 01
    Replayable by constructionRe-run any node from any upstream state. The same inputs always draw the same line.
  • 02
    Parametric, not one-shotEvery chat turn becomes a parameter. Nudge a slider; the chain re-runs from that node down.
  • 03
    Auditable wiresEvery connection is typed and logged. Hover any wire to see exactly what passed through it.

Held in your brainPurpose, work and evidenceRecall is by purpose, out of the graph

The brain

Memory that grows with the firm, not the vendor.

  • 01
    Skills you ownSave any thread as a skill. Each one carries its purpose, the work it was learned from and the evidence that earned it; a skill without evidence is never promoted.
  • 02
    Persistent across projectsThe Brain remembers your standards, from sheet naming to dim styles to detail libraries, and reuses them on the next tower.
  • 03
    No marketplace lock-inRecall comes out of your own graph, not a marketplace. There is no index and no cache in between: the brain that holds a skill is the brain that recalls it.

Local-first by default

Your work happens here. Your knowledge stays yours.

What stays on your machine, and what crosses when a node asks or when you turn cloud sync on.

Inside your machine

  • The canvassessions, nodes and wires
  • The brainyour memory and skills, on this machine
  • Your drawingsread in place by the connector
  • Provider keysthe graph holds where a key lives, never the key; anything that looks like a credential is refused
  • Skillspurpose, work and evidence you can read, diff and delete

Leaves, when a node asks

  • One model callthe prompt that node built, to your provider on your key

Leaves, when cloud sync is on

  • Your brainWhen cloud sync is on, ArchHub keeps a copy of your brain on our servers so it can reach your other devices and your firm. That copy is not end-to-end encrypted, and ArchHub's systems can read it.
If you can't read what a node does, it doesn't belong on your canvas.Your provider invoices you directly for model calls. Read the security page

Plotted on Friday, not promised

Sit down at the drafting table.

Open the canvas. Wire your first host. Read every sentence aloud to a senior architect; if they nod, you're home.
