Edit your patterns by asking ChatGPT
Knytstudio works with ChatGPT's built-in browser. Open a pattern, say what you want changed, and ChatGPT makes the edit in the editor while you watch: swap threads, add a border, merge look-alike colours, resize, rename. Every change is one Undo step.
ChatGPT's browser lists the tools Knytstudio offers on each page.
How it works
Open Knytstudio in ChatGPT
In the ChatGPT desktop app, open the built-in browser and go to knytstudio.com. The site-tools icon in the address bar means ChatGPT can use Knytstudio's tools.
Open a pattern
Turn a photo into a pattern, start a blank chart, or open one of your saved patterns. ChatGPT can find and open them for you.
Ask for the change
ChatGPT reads the chart and its threads, makes the edit, and you see it on the chart straight away. Not what you wanted? Press Undo.
Things to ask
Thread codes and colour names both work. For cross stitch, needlepoint and diamond painting every colour is a real thread: ask for a shade DMC doesn't make and Knytstudio picks the nearest thread and says which one.
“Replace DMC 321 with a darker red.”
Every stitch of that thread changes in one go.
“Add a two-stitch border in DMC 310 around the whole pattern.”
ChatGPT reads the chart size and paints the border.
“This pattern has 41 colours. Merge the ones that look almost the same.”
Fewer threads to buy, one Undo to take it back.
“Make it 120 stitches wide and keep the bottom edge where it is.”
The chart is resized around the edge you name.
“Clear the background behind the cat.”
ChatGPT reads the chart and erases the cells you mean.
“Remove the colours nothing uses, and rename it Autumn Fox.”
Palette and title, tidied.
“Find my fox pattern and open it.”
On your dashboard, ChatGPT finds and opens your saved patterns.
“Show me Halloween patterns.”
The Discover page opens with the results, and ChatGPT sums them up.
“Start a hat in adult M with DK yarn, and put a band of Selbu stars around it.”
A knitted hat worked out from size and gauge, with the motif placed and the written pattern to match.
“Read me rows 1 to 8 of this chart as written instructions.”
On a knitting chart: the rows in knitting terms, in your language, with any mistakes the chart check finds.
“Put a 2-over-2 cable up the middle of rows 5 to 20.”
The cable stitches go onto the chart, one Undo step.
“I finished row 12. Mark it knitted and show me row 13.”
In the tracker: the row is marked and the row counter moves on.
“Design a crochet hedgehog with a pointy snout, about 12 cm tall.”
In the 3D amigurumi designer: ChatGPT writes the pattern, the toy is built stitch by stitch, and the checker tells it when a count is off.
“Make the legs three rounds longer and give the body sky-blue stripes.”
Rounds and colour changes in the pattern's own terms; the written pattern and the assembly notes follow.
“Make the bunny's ears longer and switch to chunky yarn.”
ChatGPT moves the design's own sliders, changes the yarn and tells you the new size.
“I finished the top ten rows of the fox. Mark them done.”
In the stitch tracker: the rows fill in on the chart and save with your progress, one Undo away.
“How much DMC 310 is left to stitch, and where should I go next?”
ChatGPT reads your progress per thread and moves the chart to the next stitch.
“I bought DMC 310, 3865 and 444 today. Add them to my floss box.”
Your stash fills in, and the bought threads leave your shopping list.
“Which threads do I still need for my fox pattern?”
ChatGPT checks the pattern against your floss box.
“How much 14-count Aida do I need for 200 by 150 stitches?”
On the fabric size calculator: the form fills in and ChatGPT gives you the numbers.
“My gauge is 22 stitches per 10 cm. How many do I cast on for a 50 cm sweater front?”
On the gauge calculator, with a link to a row counter set to the rows you need.
“Tell me about this pattern and open it in the editor.”
On a community pattern's page: its size, threads and designer, then your own copy to edit.
Point at what you mean
ChatGPT's browser has an annotation mode: click something on the page and write a note about it. In Knytstudio every thread in the palette is a named target, so when you click "DMC 3708 Melon Light" and write "make this warmer", ChatGPT knows exactly which thread you mean and how many stitches use it.
In the amigurumi designer, ChatGPT reads the pattern with its line numbers and the checker's report, so you can ask what round 7 of the head does, or why a piece came out stretched.
Inside ChatGPT's browser the palette also has an Ask ChatGPT button with a suggested prompt. Other browsers don't show it.

You stay in charge
- Every change happens in the open editor, where you can see it, and is saved like your own edits.
- Every change is one normal Undo step.
- ChatGPT works with your login in that browser, so it can only change patterns you can change. Read-only patterns stay as they are. While the stitch tracker is open ChatGPT can mark stitches but not change the chart, and the marked-stitch lock keeps done stitches done.
- Before a garment change would redraw charts you painted by hand, ChatGPT has to ask you first.
- Downloads and publishing stay your step: ChatGPT can open the export or the publish screen, and you choose and confirm.
