Make sewing patterns inside ChatGPT
Ourlette works inside ChatGPT as an app: send ChatGPT a photo link or describe the garment with your measurements, and Ourlette drafts the pattern, shows it in the chat and gives you the printable PDF.

Add Ourlette to ChatGPT
Open ChatGPT's settings and add Ourlette as an app or custom connector with the server URL https://ourlette.com/api/mcp, if it is not yet listed in the app directory. Our setup guide for ChatGPT and Claude has the current steps. You only do this once.

Ask for a pattern
In a chat, send a photo link (a public Pinterest pin, Instagram post or shop page) or describe the garment, and add your measurements or a standard size. For clothes, height, bust, waist and hip are enough to start. Mention the length and fabric you have in mind if you know them.

See it and refine it
Ourlette drafts the pattern and shows it in the chat. Ask ChatGPT for changes, such as a longer length, a different neckline or pockets, and Ourlette redraws it. You can ask sewing questions in the same conversation. Each change goes through Ourlette's drafting engine, so the pieces stay to scale.

Print and sew
Open the printable PDF from the link Ourlette gives you, print it at true scale on A4, US Letter, a copy shop size or for a projector, and check the test square. Then follow the step-by-step sewing guide. Printing needs a Maker or Atelier plan.
What does the Ourlette app for ChatGPT do?
Ourlette works inside ChatGPT and Claude as an app (an MCP server): send the assistant a photo link or describe the garment with your measurements, and Ourlette drafts the pattern, shows it in the chat and gives you the printable PDF.
ChatGPT handles the conversation; Ourlette's drafting engine draws the pattern pieces to scale, from flat-pattern blocks and your numbers. You get the same pattern you would get on ourlette.com, without leaving the chat.
What to ask ChatGPT
Be specific about the garment and your size. For example:
- "Make me a sewing pattern for the skirt in this pin", followed by the link, and "waist 72 cm, hip 98 cm, knee length".
- "A boxy linen top with elbow sleeves and a back keyhole, women's EU 40."
- "Pull-on wide-leg trousers with pockets: height 168 cm, waist 76 cm, hip 102 cm."
Then ask for changes in the same conversation, such as "make it midi" or "add in-seam pockets", or ask which fabric to buy.
ChatGPT on its own, and with Ourlette
On its own, ChatGPT is good at explaining techniques, planning a project and answering sewing questions, but it does not draft pattern pieces to scale from your measurements. With Ourlette connected, it asks Ourlette to draft the pattern, then shows you the result and the PDF link.

How to add Ourlette to ChatGPT
Ourlette is an MCP server at https://ourlette.com/api/mcp, built on the standard that ChatGPT apps use. Until Ourlette appears in ChatGPT's app directory, you can add it as a custom app or connector with that URL, wherever your ChatGPT plan allows custom connectors.
ChatGPT's settings change from time to time, so our guide to using Ourlette in ChatGPT and Claude keeps the current steps up to date.
Plans and printing
Ourlette's plans are the same everywhere. On the free plan you can start from the 36 tested models (for a photo link or a description, the assistant starts from the closest one; drafting the exact piece is on Maker and Atelier), with 2 small AI changes per pattern and 6 AI messages a month, change options and measurements without limit, and read the sewing guide on screen.
Printing the PDF needs Maker ($7.99 a month or $59 a year) or Atelier ($19.99 a month or $149 a year), which also include the sewing guide as a PDF; 6 easy models print for free. They also draft the exact piece you show when nothing in the catalogue matches: 3 times a month on Maker, and with 12 AI credits a month on Atelier (each one a new design or a big change). Ourlette also works in Claude: see the Claude connector.
Frequently asked questions
Is Ourlette in the ChatGPT app directory?
Ourlette is built as a ChatGPT app on MCP. Until it is listed in the directory, you can add it with its server URL, https://ourlette.com/api/mcp, wherever your ChatGPT plan allows custom apps. The setup guide has the current steps.
Can I send a photo from my phone?
The most reliable way in ChatGPT is a link to the picture, such as a public Pinterest pin, Instagram post or shop page, or a description in words. To work from a photo saved on your device, you can also upload it on ourlette.com, which accepts photos and screenshots directly.
How much does Ourlette cost in ChatGPT?
The same as on ourlette.com. The free plan includes the 36 tested models to start from, 2 small AI changes per pattern, 6 AI messages a month and unlimited changes by hand; printing needs Maker ($7.99 a month or $59 a year) or Atelier ($19.99 a month or $149 a year), apart from 6 easy models that print for free. New designs drafted from scratch come with Maker (3 a month) and Atelier.
Which garments can Ourlette draft in ChatGPT?
The same as on ourlette.com: the 36 catalogue garment types (skirts, dresses, tops and shirts, sweatshirts, trousers, jeans and shorts, jackets and coats, bags, a bucket hat and home pieces), and, on the Maker and Atelier plans, anything else drafted by Ourlette's AI pattern maker, from jumpsuits and blazers to swimwear, in 4 to 8 minutes; on the Free plan, Ourlette suggests the closest tested models and Community patterns to start from. Make a toile of those new designs first; structured tailoring may need adjusting by hand.
Does Ourlette work in Claude too?
Yes. It is the same MCP server, added to Claude as a custom connector. See Ourlette for Claude.
What will you sew next?
Bring the picture. Ourlette brings the pattern.
Drafting the exact piece from a picture or words is on Maker and Atelier; for free, Ourlette suggests the closest of 36 tested models. Your pictures stay private and are only used to make your pattern.
