The 15 AI Design Tells Are a Curated Slice of Paul Bakaus's Impeccable Slop Catalog, Which Lists 67 Entries Across Nine Categories

It was posted at 2026-10-06 15:13:47 UTC by uploader handle deonnahodges under the channel nickname Deonna | AI + ChatGPT + Tech, with the audio track listed as original sound credited to the same nickname, and an unusually long 2,356-character description that reproduces the full remediation prompt and credits "Impeccable's slop catalog (impeccable.style/slop) by Paul Bakaus" under the tags #ai #claudecode #claude #webdesign #softwareengineering. At the 2026-10-07 capture, one day after posting, it showed 37,100 views, 2,411 likes, 107 comments, 265 reposts, and 1,200 saves. I read all 21 frames in tokdoc_frames/ and all 131 words of transcript.txt. Every frame is a single handheld talking-head in a home office: a cream wall with a wooden door frame on the left, a window with daylight on the right, a sheet-music stand with over-ear headphones hung on it and a keyboard behind the speaker's left shoulder, a white desk with a small green ceramic cactus and a woven basket, the speaker in a maroon off-shoulder top with long locs and clear-framed glasses, holding a small black remote in her right hand. A fixed two-line black-on-white sticker reads "15 dead giveaways your website was built with AI" through frame 019, then swaps to "prompt in comments" for frames 020 and 021. A numbered list 1 through 15 runs down the left edge and reveals one item per beat with the active item highlighted yellow; by frame 020 it reads in full: 1. purple-blue gradients, 2. Inter on everything, 3. gradient text, 4. "introducing" badge, 5. glowing halo, 6. frosted glass, 7. icon tiles, 8. identical feature cards, 9. cards inside cards, 10. side stripe cards, 11. giant "10M+", 12. 01, 02 labels, 13. pulsing green dot, 14. "supercharge" + em dashes, 15. beige + italic serif. A picture-in-picture panel in the upper right swaps a mock website per item. Frame 001 shows a dark purple-to-violet hero reading "Build the Future With AI Magic" with a pill badge "✦ New: AI-Powered Everything", body copy "Transform your workflow with our revolutionary AI platform. Purple gradients included.", and two buttons "Start Free Trial" and "Watch Demo". Frame 004 shows a light card with a blue pill badge "INTRODUCING" above "The hero headline". Frame 012 shows a three-row list with tiny gold numerals "01 02 03" beside "Discover", "Design", "Deliver". Frame 020 shows a cream hero with an oversized italic serif headline "Build faster with intelligent workflows for modern teams", a tiny gold kicker "01 / AI-NATIVE WORKFLOWS", body copy "The all-in-one platform that helps product teams ship better software in record time. Powered by AI, designed for humans.", and buttons "Start free trial →" and "Watch demo". Burned-in auto-captions run across the lower third throughout.

The attribution is correct: Paul Bakaus, impeccable.style, and the slop catalog all check out

The description credits "list from Impeccable's slop catalog (impeccable.style/slop) by Paul Bakaus."

Every part of that holds. The repository at github.com/pbakaus/impeccable describes itself as "The design language that makes your AI harness better at design," is licensed Apache-2.0, and is authored by Paul Bakaus, spelled exactly as the description spells it. The GitHub API reports the repository created on 2025-11-16T01:52:04Z with 78,150 stars and 4,641 forks as of 2026-10-07 and a push the same day. The catalog page at impeccable.style/slop exists under the title "Slop | Impeccable" and credits Paul Bakaus.

This matters because the usual failure mode of a list video is an uncredited lift. This one names the source, links it, and names the author. The creator did the thing most creators skip.

The slop catalog has 67 entries, not 15, and the video's 15 are a reordered subset

The video and the sticker both say 15. The description says "Remove or replace these 15."

The catalog page lists 67 entries across nine categories: Your Design System (4), Visual Details (8), Typography (11), Color & Contrast (7), Layout & Space (12), Motion (6), Copy (5), Imagery (4), and General Quality (10). The repository README describes the tooling behind it as "59 deterministic detector rules" plus LLM-based critique checks, so the catalog page carries more entries than the deterministic detector covers.

Nothing in the video is wrong here, but the framing invites a wrong inference. "The prompt to delete all 15 AI design tells" reads as though 15 is the complete set. It is a curated highlight reel of the most visually recognizable tells, which is the right editorial choice for a 41-second video and the wrong impression to leave about coverage. Someone who runs only the 15-item prompt and declares the site clean has skipped roughly three quarters of the published catalog, including most of the General Quality and Imagery categories that cover accessibility and broken assets.

The mapping between the two is also looser than one-to-one. The video's item 2, "Inter on everything," appears in the catalog as "Overused font" and overlaps with "Single font for everything." The video's item 1, "purple-blue gradients," maps to "AI color palette." The video's item 13, "pulsing green dot," maps to "Pulsing status dot." The video's item 14 bundles two separate catalog entries, "Generic marketing claims" and "Em-dash overuse."

The three terminal commands in the description are the real ones

The description instructs: "run npx impeccable install, then /impeccable init," then "scan the project with: npx impeccable detect ."

All three appear in the repository README as written: npx impeccable install, /impeccable init, and npx impeccable detect. The leading slash on /impeccable init is not a typo; it is a slash command issued inside the AI coding agent after the npm-side install, which is why the description separates it from the two npx calls. The description's framing, "if you can run terminal commands," correctly signals that the detector is optional and the prompt works without it.

The description's claim that Impeccable is "free and open source" is accurate. Apache-2.0, public repository, no paywall in the install path.

The mock sites in the picture-in-picture are built to demonstrate the tells, not found in the wild

Frames 001, 004, 012 and 020 show mock hero sections whose copy announces the defect it illustrates. Frame 001's body text literally reads "Transform your workflow with our revolutionary AI platform. Purple gradients included." Frame 020's cream-and-italic-serif hero reads "Powered by AI, designed for humans."

These are purpose-built demos, not screenshots of real products, and the video does not claim otherwise. Worth stating plainly because a viewer skimming could take them for examples of named sites. The one case where the demo does extra work is frame 020, which illustrates item 15: the beige-plus-italic-serif escape route. The transcript's closing line is the sharpest thing in the video, and it is a real observation about how trend cycles work: "if you switch to beige and a fancy italic serif to escape all this, that's just the 2025 version of slop." The catalog backs this up with two separate entries, "Italic serif display headline" and "Cream/beige palette," so the escape hatch is itself catalogued.

The one item worth arguing with is the em dash

Item 14 bundles "supercharge" with em dashes, and the catalog entry is "Em-dash overuse."

The catalog's own word is overuse, not use. An em dash is a standard English punctuation mark that predates every model by centuries, and a rule that bans it outright will flag correct prose written by a person. The catalog's phrasing is the defensible version. The video's compression to "plus em dashes, obviously" turns a frequency heuristic into a prohibition. For an audience that is going to paste the prompt into a coding agent and accept whatever it changes, that distinction is the difference between a copy edit and a copy rewrite.

Key Takeaways

Verified: The attribution is correct in every detail. Paul Bakaus is spelled correctly, impeccable.style/slop exists and credits him, and the repository at github.com/pbakaus/impeccable is Apache-2.0 licensed and open source.
Verified: All three commands in the description match the README: npx impeccable install, /impeccable init, and npx impeccable detect.
Clarification: The catalog lists 67 entries across nine categories, not 15. The video's 15 are a curated subset of the most visually obvious tells. Running only the 15-item prompt leaves most of the catalog's accessibility and imagery checks unchecked.
Clarification: The repository describes "59 deterministic detector rules" plus LLM-based critique checks, so the published catalog page carries more entries than the deterministic detector alone covers.
Clarification: The video's items do not map one-to-one onto catalog entries. Item 2 is the catalog's "Overused font," item 1 is "AI color palette," and item 14 bundles "Generic marketing claims" with "Em-dash overuse."
Partial correction: The catalog entry is "Em-dash overuse," a frequency heuristic. The video's "plus em dashes, obviously" reads as a ban on a standard punctuation mark.
Context: The picture-in-picture mocks are purpose-built demonstrations whose copy announces the defect they illustrate, not screenshots of shipping products.
Context: The beige-and-italic-serif escape route is itself catalogued, under "Italic serif display headline" and "Cream/beige palette." The closing observation in the video is supported by the source.
Context: Impeccable had 78,150 stars and 4,641 forks on 2026-10-07, having been created on 2025-11-16. This is a widely adopted skill, not an obscure one.
