40 Banned Phrases That Mark Your Copy as AI-Generated (with Replacements)

If your homepage says "Effortlessly streamline your workflow" near the top, your visitors already know an AI wrote it. Not because the sentence is wrong — it parses fine — but because tens of thousands of generated landing pages say the same thing, in the same words, with the same rhythm. Readers have learned to skip it on sight, the same way they skip a Tailwind blue-to-purple gradient or three identical pricing cards.

Sailop's copy dimension catches 40+ specific phrases that betray AI authorship. Each one shows up disproportionately in machine output and almost never in copy written by a human with skin in the game. Below is the full list: why each one is a tell, and what to write instead.

Why these phrases are tells

Three things make a phrase "AI slop":

1. Frequency. "Effortlessly" appears in roughly 60% of AI-generated hero subheads. In human-written copy from comparable sources, it appears in under 4%. The gap is the signal.

2. Vagueness. "AI-powered" or "next-generation" describe nothing. They could sit on a landing page for a CRM, a mattress, or a tax tool without changing a word. Human copy tends to be specific because the writer actually knows what the product does.

3. Drift. Phrases that started as legitimate marketing get drained of meaning by overuse. "Built for the modern web" meant something in 2018. By 2026 it just signals "the model ran out of specific things to say."

The copy scanner weights each phrase by frequency × distinctiveness. A phrase used once scores low. The same phrase across your hero, your features, and your CTA scores high — the way the visual scanner treats one backdrop-blur-md as noise and four as a glassmorphism habit.

The list

Action verbs that mean nothing

1. Effortlessly — In 60% of AI hero subheads. *Replacement:* describe what is hard about the alternative. "No more reading 200-line PR diffs" beats "effortlessly review code."

2. Seamlessly — The most overused adverb in generated copy. *Replacement:* name the integration point. "Plugs into your CI as a single GitHub Action" beats "seamlessly integrates with your CI."

3. Streamline — Empty productivity verb. *Replacement:* show the time saved. "Cut code-review time from 40 minutes to 8" beats "streamline your code review."

4. Unlock — Marketing genre tic. *Replacement:* describe what becomes available. "Get 50 design templates" beats "unlock 50 design templates."

5. Empower — Corporate yoga. *Replacement:* state the capability. "Ship a landing page without a designer" beats "empowers your team to ship."

6. Transform — A hedge for "we are not sure what this does." *Replacement:* state the before-and-after. "Convert an 800-line homepage into 12 reusable sections" beats "transform your homepage."

7. Revolutionize — Banned outright. Nothing on the modern web revolutionizes anything. *Replacement:* be specific about the improvement. "Catches 23 patterns ESLint and Prettier miss."

8. Supercharge — Buick-era marketing. *Replacement:* state the factor. "20x faster scanning than running pre-commit hooks by hand."

Adjectives that describe nothing

9. Powerful — Modifier with zero information content. *Replacement:* name the capability. "Catches 298 distinct AI fingerprints" beats "powerful AI detection."

10. Robust — Always means "we can't be specific about what it does." *Replacement:* state the test conditions. "Tested on 30 production codebases, 5K to 800K LOC."

11. Cutting-edge — Banned. By the time you call it cutting-edge, it is not. *Replacement:* state the actual difference. "Built on the 2026 MCP spec; works with every major AI agent."

12. Next-generation — Same disease as cutting-edge. Banned. *Replacement:* describe the generational difference. "First scanner built for AI agents, not legacy linting."

13. Innovative — A claim, not a description. Tells the reader nothing. *Replacement:* say what you do differently. "Generates procedural palettes — no other anti-slop tool ships this."

14. Comprehensive — A defensive adjective. Means "we listed a lot of things." *Replacement:* count them. "298 patterns across 7 dimensions."

15. Game-changing — Banned. Sportswriter cliché. *Replacement:* state what changes. "Drops slop scores 50–60 points in one transform pass."

16. World-class — Whose world? *Replacement:* name the benchmark. "Lower slop than Anthropic's official frontend skill on 8/10 test cases."

17. State-of-the-art — Says nothing about the actual state of any art. *Replacement:* name the benchmark, or cut the modifier.

18. Blazingly fast — Rust-forum slang as marketing copy. *Replacement:* numbers. "Scans 50,000 lines in 312ms."

Compound qualifiers

19. AI-powered — Banned when your product isn't about AI. Even when it is, "powered by" reads as filler. *Replacement:* name the model or technique. "Uses Claude Opus 4.6 to generate alternative palettes."

20. AI-native — Buzzword. *Replacement:* state the integration. "First-class MCP support for Claude Code, Cursor, Continue, Aider."

21. Cloud-native — Genre tic. *Replacement:* describe the deploy story. "Runs as a Vercel serverless function in two clicks."

22. Enterprise-grade — Classist framing. *Replacement:* name the actual capability. "SOC 2 Type 2, single-tenant on request."

23. Production-ready — Always a claim, never a guarantee. *Replacement:* show the production usage. "Gates the design-system PR at 12 teams in production."

24. Built for the modern web — Filler. *Replacement:* name the frameworks. "Works with Next.js 15+, Remix, Astro, SvelteKit."

25. End-to-end — Implies completeness without describing it. *Replacement:* list the steps. "scan → transform → CI gate → deploy."

Hero phrases

26. Welcome to our platform — The AI-default hero h1. Banned. *Replacement:* state the verb the user wants. "Stop shipping AI-generated slop."

27. The future of [thing] — Genre cliché. *Replacement:* describe a present capability. "What every AI agent should generate but doesn't."

CTAs

40. The choice is yours — Filler. *Replacement:* cut the line. The reader knows the choice is theirs.

The tells travel in packs

One banned phrase is a slip. The reason these read as machine output is that AI emits them in clusters — the same way generated design pairs bg-zinc-950 with a fade-in-up hero and a blue gradient. Here is a real generated subhead, scored:

"Seamlessly unlock the power of AI to effortlessly
 transform your workflow and take it to the next level."

  seamlessly      → #2  (hero, ×2 weight)
  unlock          → #4
  effortlessly    → #1  (hero, ×2 weight)
  transform       → #6
  take it to...   → #30
  → 5 banned phrases in 16 words. copy slop: 91/100.

No human writing for a product they understand produces that sentence. It only happens when the generator is filling space. The rewrite a person would actually defend:

"Catch the 40 phrases that mark your copy as AI-written,
 with a one-line replacement for each."

  → 0 banned phrases. copy slop: 6/100.

Shorter, says more, and survives a pitch meeting. That is the whole test.

How Sailop scores copy

The copy dimension runs every chunk of text in your codebase against this corpus. Each match contributes to the score, weighted by:

• Frequency in the file. One "seamlessly" is a yellow flag. Three is red.
• Position in the document. Hero copy ×2. CTA copy ×1.5. Footer copy ×0.5.
• Cluster proximity. Two banned phrases in the same sentence get a multiplier — that's why the example above hit 91.

Run the scanner and you get a per-file breakdown with line numbers and a suggested replacement for each hit:

npx sailop install
sailop scan ./src --dimension=copy

What to do instead

The shortcut: be specific. Replace every adjective with a number, every adverb with a comparison, every vague verb with a concrete one. The rewrite is usually shorter and always clearer.

The longer answer: write copy you would defend in a pitch meeting. AI copy is what survives committee review because nobody disagrees with it. Real copy is what one person believes and signs their name to. The 40 phrases above are exactly the ones that survive when nobody believes anything in particular — the verbal equivalent of the shadcn-default look every generated site converges on.
