CTA
62FairCopy, size, verb, cost-feel — does the primary CTA earn the click?




Problems
- 'Open' assumes existing user
- no value promise in label
- no headline echo
- weak action verb
Trust
62FairProof that the product is real, competent, and safe to try.


| Trust read | |
|---|---|
| Perseus | "Backed by Y Combinator" badge above the hero headline |
| "OVER 22,000+ TEAMS USE GREPTILE" usage banner | |
| Video card labeled "Agentic Batch Changes — Available today" | |
| Customer logo wall showing AWS, Databricks, Groq, Gamma, and monday.com | |
| Code snippet visual ("async function handler...") suggesting a developer-focused product | |
| "#1 on Design Arena" claim in the Kimi K3 link |
Value props
72FairTitle, subtitle, hero — do they sell the product's true value?

Working
- Names the category instantly
- With/without demo shows real pain
- Concrete grep-vs-3-hits contrast
Could improve
- No subhead states the outcome
- Headline is a label, not a claim
- No numbers on speed or savings
Mobile web
78FairThe phone experience as a first-class citizen.
123- Side-by-side CTA pair — Two half-width buttons split the tap target; 'Open Perseus' should stack full-bleed for the thumb.
- Four-line hero headline — Oversized serif wraps into four lines and pushes the CTAs to the bottom third of the fold.
- Terminal demo text — Low-contrast monospace output is squinting-small at phone distance.
Information hierarchy
82StrongDoes the design help or inhibit what the page is trying to say?
123- Comparison terminals cut — The Without/With Perseus proof panels enter the fold mid-sentence, so the strongest argument reads as fragments.
- Faded 'With Perseus' text — The winning side's terminal copy is rendered in low-contrast muted type, making the payoff harder to read than the failure case.
- Duplicate Open Perseus CTA — The nav repeats the hero's primary button at similar weight, splitting attention between two identical actions.
