Introduction

A week after Canva shipped its first image model, it has shipped a second one for the step that comes after generation: editing. Canva Brush is a vision-language model for design built by Canva Research, Canva's 160-person AI lab. It went live on October 29 inside Canva AI for Canva Pro subscribers. Brush looks at a design the way you do, including its layout, layers, typography and overall feel. Tell it what to change, whether that's one line of copy or every slide in a deck, and it makes the edit while leaving the rest alone.

The output is a normal Canva design, not a flattened picture. Text, images, colours and layout all stay separate elements you can grab and move by hand afterwards. Canva frames it simply: Craft generates the image, and Brush refines the design around it. We covered Canva Craft last week.

What shipped

  • Model: Canva Brush (first version, labelled Beta in the Canva AI model picker)
  • Vendor: Canva Research
  • Modality: design and image editing from text instructions. It reads the canvas and edits layout, copy, colour and imagery
  • Open vs API: closed and in-product only. The launch post doesn't mention an API or open weights
  • Where to run it today: canva.com/ai on a Canva Pro plan. Choose Brush from the model dropdown in Canva AI
  • Concrete fact: Canva says Brush is up to 69% faster on general design-editing tasks and has 46% lower cost per edit task than its previous design agent. Canva also says it matched or beat that agent's quality on most editing tasks in internal testing

How it works

Brush doesn't paint over your design. Canva describes an agentic loop: the model writes and runs code to change design elements, then inspects the page to decide what to do next. That act-and-check cycle lets it notice when one change affects the rest of the layout, for example a longer headline pushing a photo out of place, before you have to fix it.

On training, Canva says Brush started from a leading open-weights model, which it doesn't name. It was then post-trained on real design and editing tasks, using in-house design expertise and anonymised insights from users who opted in, followed by large-scale reinforcement learning. The RL reward scores visual quality, how well the layout follows design principles, and whether the task got done. Canva's professional designers set the standard for what counts as good, and the training drew on hundreds of thousands of simulated interactions.

Three things to try first

  • Restyle an image or design. Change the colour scheme, the weather or the overall mood without rebuilding anything.
  • Make one change across a multi-page deck. Update every header in one prompt instead of clicking through each page.
  • Repurpose for another channel. Turn a presentation slide into an Instagram graphic and keep the layout intact.

To start, open an existing design in the editor, or attach or link one in Canva AI, then select Brush in the dropdown. You can switch to manual editing in the editor at any point.

A paste-ready Brush prompt

Paste this into Canva AI with a multi-page deck attached and Brush selected:

Restyle this whole deck for a winter evening launch: deep navy and indigo backgrounds, soft lilac and aqua accents, warm gold for headlines. Keep every headline, body text and logo position exactly where it is. Make all page titles the same size and font. Then create a 1080x1080 Instagram version of slide 1 with the same layout hierarchy.

The final sentence tests the cross-format remix. Keep the restyle and the resize in a single request so you can see whether Brush keeps the hierarchy consistent across both.

Limits to know

  • It's for Pro users only right now. Canva says wider availability is "coming soon".
  • Brand Kit support isn't there yet. It's on Canva's to-do list, along with referencing attachments and better handling of image-heavy layouts.
  • There's no developer surface. Canva's Apps SDK has a Design Editing API, but that's for building apps inside the editor and doesn't call Brush.
  • The speed and cost figures are Canva's own, measured against its previous agent. No public leaderboard covers design editing yet, so nobody else has checked them.

Why it matters

Most AI design tools give you a pretty image you can't edit. Brush is a bet that the valuable part is the edit loop: a small, specialised model that understands document structure, built cheaply enough to run for hundreds of millions of people. With Craft for generation and Brush for editing, Canva now runs its own models at both ends of the design workflow. That's a trend worth watching in Figma, Adobe and the rest of the design-tool market.
