TL;DR #
We ran two flyer prompts three times each in Claude Design, Canva, Moda and Grafista. Claude Design, Moda and Canva each kept one layout per prompt, so their three runs read as one design in three different color combinations. Grafista returned six distinct designs, with a different palette, type system, layout and visual idea in every run.
The cause is built into the models. They predict the most likely output, and the most likely flyer is the kind they have seen most often. Steering them away from it takes a detailed prompt written in a designer's vocabulary. Grafista needs no prompt: each design starts from a Blueprint, a visual reference, instead of the model's best guess.
How we tested #
Each tool got the same two prompts, and we kept the first three results of each, unedited: 24 designs. Prompt 1 was one line plus a photo of a sourdough loaf: a modern A4 flyer for a bread festival in Ghent. Prompt 2 was a full brief with fixed copy for a community bike market in Leuven. Both are in the appendix.
Claude Design ran on Claude Opus 5.5 with high effort. No brand kit or design system was connected in any tool, since that is what a new account or a quick request gets.
We judged two things:
- Range: do three runs of one prompt give three different designs, or one layout in new colours?
- Design quality: emphasis, type, composition and art direction, reviewed the way an art director reviews a proof.
We only tested tools that return editable layers, so text, images and shapes can be changed after generation. Text-to-image tools such as ChatGPT Images return a flat picture and we explain why they are not the answer to graphic design in How Grafista fights AI slop.
The fingerprint test #
A house style, or default style, is what a tool falls back on when your prompt leaves a decision open. A flyer involves dozens of decisions: the background colour, where the image sits, which typefaces to pair, how big the date is, how the details are laid out. A prompt like "a modern flyer for a bread festival" settles none of them.
A tool with a house style fills those gaps the same way every time. Three runs of one prompt come back as one layout with different words and colours. A human designer given the same brief three times would treat it as three chances to try a different direction.
To measure it, we listed the design elements that appeared in all three runs of each prompt. The longer the list, the stronger the house style, and the easier it is to name the tool without seeing a logo.
Claude Design
In all three bread festival runs:
- The photo across the top half, the text on a cream lower half
- Small letter-spaced capitals in both top corners
- A heavy sans headline under the photo
- A WHEN, WHERE, ENTRY row in three columns
- Rusty orange as the only accent colour
In all three bike market runs:
- A heavy grotesque title top left, split over two lines
- A wheel graphic top right
- The date on a full-width colour band
- The programme on the left, prices on the right
- Times set in a monospace font
Claude Design's flyers are tidy and well spaced, with the clearest type hierarchy of the three repeating tools. The trouble is that seeing one tells you what the other two look like. Kyle Chayka described the same look in The New Yorker: cream backgrounds, rusty orange accents and letter-spaced subheadings. Coverage of his piece quotes Anthropic's own guidance calling Claude's default house style persistent. We ran Claude Opus 5.5 on high effort, and the bread flyers still land on it.
Canva AI
In all three bread festival runs:
- "Bread Festival" stacked top left in a heavy sans
- Line-drawn wheat stalks as decoration
- The photo placed in the lower half
- A cream background
- No date, venue or website
In all three bike market runs:
- An AI-drawn green city bike on the right half
- A cream, paper-textured background
- A line drawing of Leuven landmarks
- A condensed title stacked top left
Canva is the only one of the three that drew custom illustrations, and the bike flyers have a warmth the typographic layouts lack. They also read as one illustration placed three times. The bread flyers stop at a poster: title, photo and wheat, with no space planned for the details a flyer has to carry.
Moda
In all three bread festival runs:
- The photo across the top half, cream below
- Letter-spaced labels in both top corners, such as "GENT · BELGIË" and "EDITIE 2027"
- A blue rectangle or circle on the photo's lower edge
- A WHERE, WHEN, ENTRY row in three columns
In all three bike market runs:
- A heavy title top left, split over two lines
- A ring or wheel shape top right
- The date in a coloured block
- The programme on the left, prices on the right
- A solid footer band carrying the website
Moda's headlines change more than its layouts: "Ghent Bread Festival", "Rise & Break Bread." and "Broodfeest Gent" sit in near-identical frames. Put its bread flyers next to Claude Design's and the structure matches element for element: photo on top, corner labels, three columns of details. The accent colour is the main thing that tells them apart.
Why AI design tools default to a house style #
The repetition comes from how generative models work. A model builds its output one piece at a time, each time picking what is most likely given the patterns in its training data.
Anthropic calls the design version of this distributional convergence. Safe choices that work everywhere dominate the web pages models learn from, so without direction the model samples from that high-probability centre. Anthropic's own example: ask for a landing page without guidance and you almost always get the Inter font, a purple gradient on white and minimal animation.
Training on human feedback narrows the range further. Researchers studying this effect, known as mode collapse, found that people rating model outputs systematically prefer familiar answers, and models tuned on those ratings drift toward the typical one.
The same pattern shows up across users. In a study published in Science Advances, short stories written with ideas from GPT-4 were rated as more creative one by one, but they were more similar to each other than stories written without AI. Design tools built on the same kind of model make the same trade: each flyer looks competent, and side by side they look alike. That is what the fingerprint test above shows.
Getting off the default takes design skills
You can steer these models, but only by telling them what to do instead. Anthropic says the more specialised the task, the more context the model needs, and that for design the guidance has to cover typography, colour theory and backgrounds, naming the defaults to avoid and the alternatives to prefer. Even with that guidance, its team found the model sliding to the next common choice, such as the font Space Grotesk, after being told to avoid.
Claude Design's help centre gives similar advice: import a complete design system, and describe the goal, layout, content and audience in each prompt. In practice, asking for "a modern flyer" gets you the average modern flyer. Getting anything else means naming a type pairing, a palette, a grid and an art direction, which is a designer's vocabulary.
Without both skills, prompt writing and design knowledge, you get the default. Most people who open an AI design tool have neither, which is usually why they opened it.
How Grafista approaches it
Grafista removes the prompt and uses Blueprints, which are visual references, apapting users’ content to that direction. Blueprints can also be combined with Brand Kits for a more personalised result.
The decisions a prompt would have to spell out in words, type, palette, layout and art direction, come from the Blueprint. The model is not left to fill them with its most likely guess, so the output does not converge on one house style. Since most people know the look they want when they see it, picking that look is enough: no prompt and no design vocabulary required. And when no blueprint is chosen, the model still has a vast library of different styles and art directions it can refer to.
Grafista: six runs, six styles #
Nothing appeared in all three Grafista runs of either prompt: not a background colour, a layout, a typeface or a place for the date. Each run picked its own design direction and built the page around it.
Bread festival
1. Night programme: The photo fills the page in near-black, and a programme of four events over three days runs down it: event names in a cream serif, times and venues in a small sans. Each event sits at a real Ghent location, from the Stadshal to the Groot Vleeshuis. It reads like a festival's printed programme, not a poster template.
2. Editorial timetable: A mint page with "Brood" set large and four sessions in rows: oversized day numbers, session titles, labels and ticket details. Our photo and three more bread photos alternate with the session details in a checkerboard.
3. Swiss split: Beige, with a heavy three-line title across the top and a small red kicker above it. An intro and a black date box hold the left column, and the photo is cropped into the lower right half.
Bike market
1. Spotlight: Deep purple, with a warm beam falling from the top right onto a drawn bike standing in a pool of light. The text runs down the left in cream and amber.
2. Sticker sheet: Pink, with a hand-lettered title, white cards with blue offset shadows, monospace times and small star marks. It is the loosest, most playful design in the test.
3. Calendar: Orange, with the key facts in rounded pills and a handwritten "17 Apr" circled at the top. A Thursday, Friday, Saturday calendar strip fills the bottom of the page, with 16 struck through and 17 circled.
The six use six palettes: cream on black, mint and teal, beige and red, purple and amber, pink and blue, orange and yellow. The type ranges from a classic serif pairing to a heavy grotesque to hand lettering. Two of them turn the content into the layout: a schedule becomes a timetable grid, and a date becomes a calendar.
Design quality #
We reviewed every design the way an art director reviews a proof: where the eye lands first, whether the type suits the subject, how the page is built, and whether there is an idea behind it.
Emphasis
Claude Design and Moda handle emphasis competently, and identically: a heavy headline, then the date on a colour band or block, then everything else. The order is clear, but it is the order of a web page, hero first and details below.
Canva's bike flyers give the illustration the most weight, and in one of them decorative arrows and chevrons compete with the text for attention. Its bread flyers have a strong title and nothing beneath it for the eye to move on to.
Grafista sets one focal point per design and builds the hierarchy around it: the lit bike in the spotlight, the circled 17 on the calendar, the oversized day numbers in the timetable, the three-line title in the Swiss split.
Type
Claude Design paired a heavy grotesque with monospace labels and times in all six designs. Monospace type comes from code editors; on a bread festival flyer it reads as software, not bakery. Moda uses the same pairing of a wide grotesque and letter-spaced mono labels, with a single serif italic subtitle in one bike flyer.
Canva sets the bike flyers almost entirely in condensed bold sans, so the body copy reads as dense blocks. Its most considered choice is a green serif "Ghent" under a geometric sans title in one bread flyer.
Grafista changed type with each concept: a serif for event names on the night programme, a friendly geometric sans on the timetable, a heavy grotesque with a red kicker on the Swiss split, hand lettering on the sticker sheet, and a handwritten "17 Apr" note on the calendar.
Composition
Claude Design and Moda compose like websites printed on A4: a hero image across the top half, a row of labelled columns, a footer band. In Moda's bread flyers, this leaves wide empty gaps between the headline and the details.
Canva's bike flyers put the illustration in the centre and squeeze the programme, prices and bring sections into small boxes in the bottom third, so the information looks cramped next to a generous drawing. Its bread flyers are posters rather than flyers: a title, a photo and decoration, with no area composed for information.
Grafista's compositions follow the content. The timetable alternates text and photos in a checkerboard, so four sessions read as a sequence. The spotlight's diagonal beam leads the eye from the corner to the bike. The Swiss split runs an asymmetric grid, and the calendar places its date idea at the base of the page, where it anchors everything above it.
Art direction
This is where the gap is widest. Claude Design and Moda show no visual idea beyond the subject's most obvious symbol: the bread photo goes on top, and the bike becomes a wheel or a ring. Canva has the most imagery, with AI-drawn bikes, Leuven landmarks and wheat stalks, but it is literal decoration in a recognisable AI illustration style.
Each Grafista design has a concept you can name in two words: night programme, editorial timetable, Swiss split, spotlight, sticker sheet, calendar. The same bread photo appears as a darkened full-page backdrop, as one tile in a grid, and as a cropped panel.
Production errors
One Claude Design bread flyer runs off the page, cutting off its website and the line "BRING A BAG." Two Canva bike flyers have distorted lettering, in the PROGRAMME heading and in the words "refurbished city bike". Grafista's six designs had no overlaps, clipped text or garbled lettering. We did not count the moda.app badge in the corner of Moda's designs as a design choice.
