Offcut

Offcut · for small shops and DIY woodworkers

Describe the piece. Get the cut list.

Tell Claude or ChatGPT what you want to build, from a shelf to a whole kitchen, and watch it appear in Offcut as real boards with sizes, materials and joints, ready to cut. Rather draw it yourself? The tools work the way they do in SketchUp.

What you get

Your AI assistant designs it

Describe the piece in your own words and watch it appear in your project: boards, joints and all, fitted to your room, with joinery your tools can make. Change anything, or undo it a step at a time.

Or draw it yourself

Rectangle, Push/Pull, Move and Rotate, as in SketchUp, on boards that know their material, grain and edge banding.

Recipes for the usual pieces

Cabinets, drawer boxes, shelving and fronts: set the sizes, get the boards and joints.

Cut list included

Sheets laid out, cuts numbered, offcuts sized.

Design with AI

Furniture you can build, not a pretty picture

Image generators give you a picture. Offcut gives your assistant real boards to work with, so what it designs has sizes, materials and joints, and comes with a cut list. Add Offcut to Claude or ChatGPT as an MCP connector and sign in once.

Everything it does lands in your project as normal steps, so you can see it, change it or undo it.

You A kitchen run for my workshop: a 600 base cabinet with three drawers, an 800 one with two doors, a tall open shelf unit beside them and wall cabinets above. Birch ply fronts.

Assistant Done: five cabinets, 66 boards, every part held. The fronts come out of one 2500 × 1250 sheet of birch ply, and the carcasses need four sheets of 18 mm PAL.

Share it

Show a friend. Build it together.

Send a link and they see your design in 3D, every size and the cut list, without signing up. Need a second pair of hands? An edit link lets them work on it with you, and you both see each other's changes as they're saved.

Turn a link off and it stops working at once.

For showing it off: they turn it around, check the sizes and open the cut list. Nothing can be changed.

Edit link

For building it together: they draw and change boards with you, live, in the same project.

When it's time to cut

The cut list comes with it

  • ESheets laid out for you. Every part packed onto standard sheet sizes, trying several orders and keeping whichever buys the least.
  • FCut in order. Guillotine cuts numbered on each sheet, and the offcuts measured so you can use them later.
  • GEdges and grain. Banding per edge with totals, grain kept along the length, mirror-image parts merged.
  • HSolid wood too. Glue-up plans for panels, and what's already in your shop used first.

Questions

Is it free?
Yes, everything in Offcut is free to use today, with no card needed. If that ever changes, you'll hear it from us first.
Do I need to install anything?
No. Offcut runs in your browser on a Mac or PC. A trackpad or a mouse with a middle button both work.
Which AI assistants work with it?
Claude and ChatGPT, or any app that takes MCP connectors. You add Offcut's address as a connector and sign in to Offcut to allow it.
Does my friend need an account to see my design?
No. A view or edit link opens the project straight away, in their browser. You can turn either link off whenever you like.
What can I design?
Furniture made of boards: cabinets, shelving, desks, beds, boxes. Shaped edges, live edges and round parts too.

Draw once. Cut once.
