Architectural modelling · browser-native

Sketch it by hand.
Keep editing it in 3D.

Draw with the pen or type a brief. What comes back is a parametric model — every wall, door, and window still yours to change.

Work with your own AI

Keep using the assistant you know. Let it read your Cloud project and propose changes, or exchange a portable package with any AI chat.

  1. Open your assistant

    In Claude, open Settings → Connectors → Add custom connector. Choose a remote server and enter the details below. Workspace administrators may control connector access.

    Open Claude

  2. Connect VerSketch

    Server URL
    https://versketch.xyz/api/agent/mcp
    OAuth client ID
    aiv_claude

    Choose OAuth, leave the client secret empty, and sign in with AIVerID when prompted. Review the permissions in your assistant before approving.

    If your assistant asks for scopesprofile email versketch:read versketch:validate versketch:propose

  3. Ask your AI to check the connection

    Send this request in your AI chat. Reading real project data confirms access; opening this guide alone does not.

    Use VerSketch to read the authoring schema and list my Cloud projects. Do not create or change anything. Tell me whether you can read my projects and which authoring features are supported.

  4. Describe a change, then review it on the canvas

    Ask your assistant to create a design or edit an existing one. It reads the model, checks its proposed changes, and returns a review link. Open the link in VerSketch to preview and accept or reject the proposal. Your accepted work is saved through the project’s normal save flow.

Remote connections work with your Cloud projects. Device-only projects stay in your browser unless you choose to share a package or move them to Cloud.

An authorized connection can read your account’s Cloud projects and propose changes. It cannot accept proposals for you. Never paste access tokens into an AI chat.

Three things, one canvas

From the first pen stroke to a model your whole toolchain can open.

Pen-first on iPad

Draw with the pen, navigate with your fingers. Walls snap to the grid, to columns, and to nearby geometry — precise input on the device you actually sketch on.

Editable 3D, not a frozen picture

Draw in the plan, upload a sketch, or type a brief, then preview what the AI proposes and accept or reject it. Every wall, door, and window stays editable — and the 3D model follows along.

Code hints that cite their source

Every rule points at the document it came from, so you can tap through and read the original text yourself.

Who decides what

The model reads the drawing and raises a flag. It never signs anything.

Your work leaves with you

13 export paths: your own .versketch.json file on every plan, and 11 more formats plus a VerCivil handoff on Pro and Studio. Open formats first — send files to any desktop CAD or BIM workflow.

Built for the early hours of a project

Architects

Concept and schematic work, then a file that opens cleanly downstream.

Interior designers

Plans and walkthroughs a client can read in the room with you.

Small studios

No seat you have to justify before you know the project is real.
