Crossover Labs wants everyone to be able to use knock knock hello, including people who use a screen reader, a keyboard instead of a mouse, voice control, screen magnification or captions.
The standard we aim for
We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at Level AA, published by the W3C.
Where we are today
knock knock hello partially conforms to WCAG 2.2 Level AA. That means most of it meets the standard and some parts don't yet. The gaps we know about:
- The sample conversation on the front door plays on a loop and has no pause button yet. It does not play at all if your device is set to reduce motion.
- Chat answers, logos and links come from the website you knock on. We can't fix accessibility problems on that website itself.
- Payment for a featured listing happens on Stripe's checkout page, which Stripe builds and maintains.
What we do about it
- We run automated WCAG 2.2 AA checks on our pages and fix what they find.
- We check new features with a keyboard and a screen reader before we release them.
- We fix problems in the code itself. We don't use accessibility overlay widgets.
Tell us about a problem
If something on knock knock hello doesn't work for you, email adam@crossoverlabs.ai. Tell us the page and what went wrong. We reply within 5 business days. While we fix it, we'll help you get the information or finish the task another way.
Technical details
knock knock hello uses HTML, CSS and JavaScript and is built to work with current versions of the major browsers and screen readers (VoiceOver, NVDA, JAWS, TalkBack).
Information for customers in the European Union
This section gives the information the European Accessibility Act (Directive (EU) 2019/882, Annex V) asks service providers to publish.
The service
knock knock hello lets anyone type in a website address and chat with that website about what is on its pages. Website owners can pay to feature their site on a public board ranked by bid.
How it works
Enter a website address and ask your questions in the chat. To feature a site, enter its address and a bid in whole dollars, then pay on Stripe's checkout page. The listing appears on the board once the payment goes through.
How it meets the accessibility requirements
We design and test knock knock hello against WCAG 2.2 Level AA, the web content requirements used by the European standard EN 301 549. Our status is partially conformant, with the gaps listed above. We check that images have text alternatives, pages work with a keyboard, text stays readable when zoomed to 200 percent, colors have enough contrast, and forms have labels and clear error messages.
