Example use cases
UX copy length audit for signup form
“Rank the text lengths of all elements in the form with id 'signup' on https://myapp.com/register, using the term 'email' — I want to see how the new copy compares to the old version texts ['Enter your email', 'Please provide your email address'].”
Form label length comparison from raw HTML
“I have this HTML snippet with a form — can you rank the text lengths in the form with id 'checkout' using the attribute 'id', search term 'checkout', and compare against these previous texts: ['Billing details', 'Shipping address']? Here's the HTML: <!doctype html><html><body><form id="checkout">Billing details form for your order</form></body></html>”
Tracking text length changes across form iterations
“Check the form at https://shop.example.com/contact with attribute 'data-kind' set to 'contact-form', search term 'message', and rank its text length against my previous versions: ['Send us a message', 'Get in touch with our team', 'Contact support'].”
