Glif’s Tool to Verify Its Own Outputs

We ran our tool in public. For each brief we generated 2 designs with different models, sent the pair to the analyzeMedia tool, and published what came back unedited.

How These Were Made

Every pair on this page was produced in a single Glif session, with no cherry-picking between runs. The process was the same each time:

  1. Write one brief.
  2. Generate 2 designs with different image models.
  3. Lay both on one canvas and send it to the analyzeMedia tool with the brief attached. To remove bias, every pair is scored in both orders so the tool can’t be swayed by which image it saw first.
  4. Publish the verdict.

Photography

analyzeMedia · Scored in both orders · Winner B

Brief

A lifestyle product photo for a premium ceramic coffee mug brand — one mug on a sunlit wooden cafe table, warm morning light, shallow depth of field, editorial quality, space at the top for a headline.

Deliberately weak

Overhead daylight, laptop and menu board crowd the frame, mug carries its own branding text

Strong

Warm golden-hour light, single mug, clear space above for a headline

Verdict

Image B succeeds by delivering a sophisticated, editorial-grade composition that focuses on a single ceramic mug bathed in warm, golden morning light, leaving the exact negative space at the top required for a headline. In stark contrast, Image A completely misses the premium, minimalist aesthetic by crowding the frame with a chaotic array of extra mugs, laptops, food, and distracting, garbled text. Ultimately, Image B’s serene color harmony and elegant depth of field establish a clear, high-end focal point, while Image A’s over-saturated clutter fails to convey the requested calm cafe atmosphere.

Fashion Sale Ad

analyzeMedia · Scored in both orders · Winner B

Brief

Create a trendy and eye-catching social media advertisement for a fashion sale, showcasing a stylish product with a significant discount and highlighting convenient delivery and return options. Playful, modern, energetic aesthetic: a high-contrast, vibrant palette combining bright pink and neon green (from the model’s top) with a dark gray background and a rustic brick wall. Typography mixes an elegant script for 'Great' with a bold, clear sans-serif for 'OFF,' the discount, and the delivery information. Asymmetrical layout with the model as a strong focal point on the left, balanced by prominent vertical 'Great OFF' text on the right, with scattered white plus signs for a whimsical graphic touch.

Deliberately weak

No brick wall, pink 'OFF' instead of neon green, discount partly hidden behind the model, sparkles instead of plus signs

Strong

Brick wall, plus signs, and a fully legible neon-green discount stack, exactly as briefed

Verdict

Image B wins because it executes the brief’s aesthetic spec point for point: the dark gray-to-brick backdrop, the neon-green 'OFF' and '50%' stacked legibly down the right edge, the scattered white plus signs, and a bold black-on-neon-green delivery bar that reads at a glance. Image A swaps in a dark green ground with no brick, renders 'OFF' in pink instead of the specified neon green, and lets the model’s body cover the '0' in '50%' — the one character the ad most needs visible. Its sparkle motifs replace the requested plus signs, and the whole composition is echoed by a blurred duplicate bleeding off the edges, which reads as a rendering artifact rather than a deliberate design choice.

Brand Web Page

analyzeMedia · Scored in both orders · Winner B

Brief

Create a sophisticated and visually appealing web page design or digital advertisement for a minimalist fashion brand, featuring product imagery, compelling brand messaging, and clear calls to action, all while maintaining a clean and elegant aesthetic. Modern, minimalist, elegant aesthetic with predominantly sans-serif typography: large, bold headlines ('EASY', 'CHIC') for impact and smaller, lighter text for details. Ample negative space on a light gray background conveys sophistication and uncluttered luxury. The composition is asymmetrical but balanced, with a central triptych of product images as the strong focal point. Color harmony comes from a restrained monochromatic gray palette that lets the photographic content’s own hues shine, with subtle graphic elements like a curved dark gray shape, a hamburger icon, and a bottom bar adding a contemporary touch.

Deliberately weak

Serif headline instead of sans-serif, one photo instead of a triptych, garbled body copy, blue CTA breaks the monochromatic palette

Strong

Sans-serif hierarchy, three-photo triptych, monochromatic gray palette, legible copy throughout

Verdict

Image B wins because it executes the brief’s minimalist fashion-site spec cleanly: a bold sans-serif 'EASY CHIC' headline anchors the left side, the three-photo triptych sits on a soft curved gray shape as its focal point, and the restrained gray palette lets the product photography carry the only real color. Image A trades the sans-serif headline for a serif one, replaces the triptych with a single photo, and pads the page with dense columns of garbled, half-legible text ('PROTA GROUT LUREGSIT SCUP') that undermines the brief’s call for a 'clear visual hierarchy' and 'compelling brand messaging'. Its solid blue CTA button also breaks the monochromatic gray palette, where the brief intended color to come only from the photography.

Illustration

analyzeMedia · Scored in both orders · Winner B

Brief

A children’s-book-style illustration: a small fox reading a book by lantern light in a hollow tree, cozy autumn palette, hand-drawn gouache texture, clear silhouette, storybook charm.

Deliberately weak

Competing detail, mixed rendering styles, garbled book text

Strong

Consistent gouache, lantern as the true light source

Verdict

Image B triumphs by masterfully channeling the quiet, magical essence of a children’s book through a beautifully restrained autumn palette and a clear, uncluttered silhouette that keeps the focus entirely on the cozy fox. While Image A descends into visual chaos with a cluttered composition of competing high-contrast elements and illegible, garbled text on the book, Image B delivers a cohesive, professionally executed gouache texture and legible, charming details. This restraint in composition and color allows Image B’s soft lantern glow to establish a perfect, unified storybook mood.

Ad Visual Hierarchy

analyzeMedia · Scored in both orders · Winner B

Brief

Create an informative, appealing social media post/ad for a skincare product called 'Avocado Lotion,' highlighting its key benefits, in a playful, friendly, soft, modern-clean design with an easy-to-read layout.

Deliberately weak

No product in frame, headline barely separates from its background

Strong

Product bottle in shot, bold high-contrast headline, organic soft-edged shapes

Verdict

Image B succeeds by being a complete advertisement: the product bottle sits in frame alongside the ingredients, and a bold, fully-legible headline anchors a clean run of benefit lines beneath it. Image A omits the bottle entirely, so the ad never actually shows what it’s selling, and its headline is set in a pale serif that all but disappears against the cream card behind it. Image B’s rounded, organic shapes and scattered avocado accents deliver the brief’s 'soft, playful' brief just as well, without sacrificing the 'easy-to-read' requirement it was also asked for.

Travel Ad

analyzeMedia · Scored in both orders · Winner B

Brief

Create a compelling and visually engaging travel advertisement to promote Bhutan as a desirable destination, highlighting its cultural and natural beauty, offering a clear discount, and providing prominent booking information. Modern, dynamic, and inviting aesthetic with strong contrasts and an asymmetrical composition. Typography is primarily sans-serif; 'BHUTAN' stands out in a bold, heavy weight in bright yellow, while the descriptive text stays clean and highly legible. A dark background gives the vibrant yellow and white elements excellent contrast. Tilted, rhombus-shaped image crops and the airplane’s curved path add a sense of movement, and the color palette of dark blue/black, bright yellow, and white guides the eye from the destination name to the offer to the call to action.

Deliberately weak

No diamond crops, thin title weight, garbled body copy, symmetric layout

Strong

Diamond crops, curved flight path, bold yellow headline, clean legible copy

Verdict

Image B wins because it builds the exact dynamic, asymmetrical layout the brief called for: a heavy bold-yellow 'BHUTAN' headline anchors the left side, the tilted rhombus photo crops and the airplane’s curved dashed path carry the eye down and across the right side, and the sequence lands cleanly on the yellow '30% OFF' badge and filled 'BOOK NOW' button. Image A centers everything instead, crops its photos as plain rectangles with no diamond shapes or sense of motion, sets 'BHUTAN' in a thin rather than heavy weight, and undercuts its own legibility with a line of garbled body copy ('rappiness aren:d raking') that the brief’s 'highly legible' requirement rules out entirely.

Color Palette Slide

analyzeMedia · Scored in both orders · Winner B

Brief

Create an informative graphic or presentation slide explaining the significance of brand color palettes, featuring a compelling visual example, concise explanatory text, and a sample color scheme. Clean, modern, minimalist aesthetic with a strong emphasis on informative content. Typography uses a classic serif font for all text elements, with good hierarchy by size and placement, and text left-aligned within its cells. Generous negative space surrounds the text and central image. The grid composition is well-balanced, with a vibrant central image as the clear focal point, framed by the introductory question. Color harmony is warm and earthy, drawing from a desert scene: a soft light beige background complements deeper brown palette tones and contrasts with a rich green accent color. Thin, subtle grid lines maintain structure without being obtrusive.

Deliberately weak

Thick obtrusive dividers instead of thin grid lines, sans-serif type, centered text, white background, one swatch labeled with a plain word instead of a hex code

Strong

Thin grid lines, consistent serif typography, left-aligned text, and a beige palette matching the brief

Verdict

Image B wins on the structural spec the brief is most explicit about: it uses thin, subtle grid lines rather than thick dividers, sets every text element in a consistent serif face, left-aligns the paragraphs within their cells, and keeps the soft beige background the brief calls out by name. Image A breaks nearly every one of those directives at once — its dividers are thick and obtrusive rather than subtle, its headline and body copy switch to a sans-serif face, its paragraphs are center-aligned, and its background is plain white instead of beige. Both candidates garble some of their body prose, but Image A’s failure goes further: one of its six color swatches is labeled '#hocolate', an entirely invalid hex code that reads as an English word, which is a harder failure to miss than the more subtly malformed codes in Image B.

Typography

analyzeMedia · Scored in both orders · Winner A

Brief

An event poster for a jazz night: 'BLUE NOTE SESSIONS — Friday 9PM — The Cellar Room'. Bold editorial typography, strong hierarchy, confident use of negative space, two-color palette.

Intended as the weak one

FLUX Turbo

Intended as the strong one

Gemini 3.1 Flash Image

Verdict

Image A triumphs by delivering a sophisticated, editorial-grade design that perfectly captures the moody elegance of a jazz night through its authoritative, highly cohesive typography and masterful use of negative space. While Image A utilizes its gold and navy palette to establish a clean, balanced contrast and a clear hierarchy of information, Image B falls short with a disjointed mix of clashing, squeezed fonts that crowd the bottom of the layout. Ultimately, Image A’s confident composition feels intentional and professionally polished, whereas Image B’s disorganized type choices and floating elements result in a cluttered, template-like appearance.

Webinar Promo

analyzeMedia · Scored in both orders · Winner B

Brief

Create a modern and professional promotional graphic for a webinar or online event, featuring a relevant action-oriented image, a clear title, and essential event details like date, time, and speakers, suitable for social media or digital advertising. Modern, clean, professional, minimalist aesthetic. Typography is primarily sans-serif, with 'WEBINAR' large and bold to command attention, while event details use a monospaced or fixed-width sans-serif for a structured, technical feel. Generous negative space surrounds the main title and lower text blocks. The composition is balanced: the prominent title and a striking image anchor the upper half, while detailed information is systematically presented in the lower half. Thin white horizontal lines serve as visual separators. A limited palette of dark gray, light beige, and white creates strong contrast, letting the vibrant colors and action of the welding image become the focal point.

Deliberately weak

Navy-and-teal palette instead of dark gray/beige/white, thick colored bars instead of thin white lines, and no welding photo despite the brief specifying one

Strong

Dark gray/beige/white palette, thin white line separators, monospaced detail block, and the welding action photo the brief specifically called for

Verdict

Image B wins because it includes the one concrete content element the brief names outright — a welding photo, sparks and all — and builds the rest of the layout around it exactly as specified: a dark gray background, thin white horizontal lines separating the title block from the details block, and a monospaced date/time/duration line that gives the lower half the 'structured, technical feel' the brief asks for. Image A swaps the welding photo for an unrelated flat illustration of a man on a laptop, recolors the whole graphic into dark navy and teal instead of the specified dark gray, beige and white, and replaces the thin line separators with thick colored bars labeling 'DETAILS' and 'FEATURED SPEAKERS'. Both candidates have a small copy slip — Image B mislabels its speakers’ titles as 'Professional Manufactor' — but that’s a much smaller miss than swapping out the brief’s central image entirely.

Beauty Brand Ad

analyzeMedia · Scored in both orders · Winner B

Brief

Create a visually appealing and aspirational advertisement for a beauty brand, showcasing its identity, promoting its products, and conveying a message about self-expression through makeup. Clean, elegant, modern aesthetic fitting a premium cosmetic brand. Typography employs a simple, readable sans-serif font for both the brand name and the accompanying quote. Ample spacing and padding around the logo and text elements contribute to an uncluttered, sophisticated look. The color palette combines a soft, muted pink/beige, a rich forest green for product packaging, and vibrant, earthy tones from the model’s makeup, creating a sense of luxury and natural beauty. The composition balances the brand identity and quote on the left against a striking portrait on the right, with a product display at the bottom anchoring the design. The model’s captivating eyes act as a strong focal point.

Deliberately weak

No forest-green packaging, a saturated coral background with a busy floral pattern instead of muted pink/beige, and a wider crop that pulls focus away from the eyes

Strong

Forest-green product packaging, a muted pink/beige background, and the model’s eyes framed as the clear focal point, exactly as briefed

Verdict

Image B wins on the palette and composition the brief is most specific about: the soft muted pink-beige background, the rich forest-green caps unifying all four products at the bottom, and a tight portrait crop that puts the model’s eyes front and center as the focal point. Image A actually gets the typography detail right — its logo and tagline are genuinely sans-serif, where Image B’s are a thin serif instead — but it misses nearly everything else the brief specifies: the background is a saturated coral overlaid with a busy floral pattern rather than a muted, uncluttered pink/beige, and none of its products carry the forest-green packaging the brief calls out by name. On balance, Image B matches more of the brief’s concrete, checkable details, even with its own typography slip.

Skate Brand Ad

analyzeMedia · Scored in both orders · Winner B

Brief

A skateboard brand advertisement using a candid, high-flash street photograph aesthetic. The image should feel genuinely captured — raw, unposed, suburban — not like a commercial shoot. Minimal branding, maximum authenticity. The photography style draws from early 2000s skate magazine culture: harsh on-camera flash bleaches out the immediate foreground while the background falls into natural dusk or night darkness. A suburban teenager mid-ride on a street, with cracked asphalt, parked cars, and residential houses behind them. Clothing is casual and real, not styled. The flash creates hard shadows, slight overexposure on skin and concrete, and a gritty film-grain texture that makes the image feel discovered rather than made. A small, confident brand logo or wordmark in white sits in the top-left corner, restrained, almost like a stamp. Minimal to no additional text. The ad sells the feeling, not the product.

Deliberately weak

Symmetrical, evenly lit composition and a posed mid-air trick read as a produced editorial shoot rather than a candid snapshot; the background stays well-lit instead of falling into darkness

Strong

Off-center, unposed framing, a background that genuinely falls into dusk darkness, and visible film grain read as a candid snapshot rather than a shoot

Verdict

Image B wins because it nails the brief’s core instruction — that this should feel genuinely captured, not staged. The subject rides off-center rather than performing a centered hero trick, the background of ordinary houses and parked cars falls into real dusk darkness the way on-camera flash actually behaves, and the visible grain reads as a found photograph rather than a produced shoot. Image A gets the black-and-white flash look right, but its perfectly symmetrical street, evenly lit houses on both sides, and a posed mid-air ollie caught dead-center in frame read as exactly the commercial skate-ad aesthetic the brief explicitly asked to avoid. Image A’s wordmark is technically closer to the brief’s 'white' lettering, where Image B’s sits inside a white tag with black type, but that’s a much smaller miss than swapping candid for composed.
