New Polyform 0.9 — agents design while you watch

Your files never leave. Your agent still gets in.

A pro vector design tool for interfaces, games and graphics. Every project is a folder on your disk that always opens, and an AI agent can work in it while you watch, one undoable step at a time.

The Polyform editor. An AI agent is laying out a stats card on the Mobile app page, step 3 of 6, with a Hold button in its chip; the layers panel and inspector show the selection.

Works with

Claude Code
Cursor
VS Code
any MCP client
.fig import

001Your files

Your work is
a folder.
It always opens.

A project is a plain folder on your disk: the scene, an undo history and your assets. Copy it, zip it, put it in Git. It opens with no network, and it keeps opening if you ever stop paying.

Opens offline, always
Opens and exports without a subscription
Undo that survives restarts, kept on disk
Assets deduplicated by content hash

002Agents

An agent on your canvas.
You hold the pen.

Polyform runs an MCP server inside the app. Claude Code, Cursor or any MCP client edits the open document while you watch, and only with the permissions you grant.

> make the stats card three rows,
    12 px apart, and check it

● get_document  Mobile app · 3 pages
● set_step  "Laying out the stats card"
● edit_document  3 rows · gap 12
    ✓ one undo: "Stats card rows"
● get_node_image  looking at the result

  Done. Three rows, 12 px apart.
  Press Hold in Polyform to stop

The canvas while the agent works: a chip reads “Laying out the stats card, 3 of 6” with a Hold button; the agent’s cursor is adding row 3 to a stats card; the history panel lists its edits, each marked AGENT, and one marked YOU.

01
You decide what it can do

Reading, seeing, selecting and editing are separate permissions. Editing starts off, and you can revoke any of them mid-session.
02
You see it work

A frame around the canvas and a chip that says what it is doing, step by step. Press Hold and it waits for you.
03
Every edit is one undo

Each agent batch lands as one labelled entry in history, marked AGENT. Step back through it like your own work.

003The editor

A real editor.
Not a toy.

Everything a working designer reaches for daily, on a Rust and WebGPU engine that stays fast when the file gets big.

Vector networks, not just paths

Branch a point three ways, knife a shape in two, then paint the regions you made.

Type that holds up

HarfBuzz-grade shaping in the core: text lays out the same on every machine.

Components that stay in step

Edit the master and every instance follows.

Auto layout

Rows and columns with gap, padding and alignment that move your layers for you.

Shaders you wear like paint

13 built-in materials plus your own WGSL shaders, saved inside the project like any other asset.

iridescent
foil
dotgrid

An engine, not a web page

WebGPU draws 100,000 shapes at 60 fps in one draw call.

0.18 ms

CPU per frame · 100k shapes

004Games

Made for games,
too.

Level art, UI and promo graphics in one tool. A tilemap holds ten thousand tiles as one layer, so a whole level stays light, and an agent can paint it for you.
