Frustratingly there is very little technical information to be found on the website.

They're essentially saying "hey, here are some words we made up, now trust us, it works!" without delving into any real detail with examples.

From the website:

The method is called biochronometrics and it maps behavior based on a series of complex algorithms. 5 million live tests show that bots can’t mimic human behavior when biochronometrics are applied.

That being said, yes, I would love to see some more technical details on the implementation...

The only technical details I could find on the site were:

The method is called biochronometrics and it maps behavior based on a series of complex algorithms. 5 million live tests show that bots can’t mimic human behavior when biochronometrics are applied.

and:

NoMoreCaptchas analyses behavior while a user name and password are being entered and determines if the user is human or a bot.

So presumably it monitors mouse and keyboard events during login; particularly the timing, judging from the name "biochronometrics"...

The research seems to be from here... http://oxford-biochron.com/

And it's linked to google, facebook, and "others" ...

Since I don't use google, facebook, or "others", I don't think it would work for me.

EDIT: I guess I was looking at the wrong product. However, my guess is the system measures mouse movement within the window or click rate or some variation of these. It said somewhere that an HTML5 browser is necessary, so I imagine the product would not work with a text browser. In any case, it seems dubious. If Bayesian email filters can be fooled, so too can an otherwise untested human noise detector in the "real" world of the cloud...

I wonder his this fares with auto-filled forms by the browser and things like lastpass / onepassword

The method described is rather vague, but I think monitoring mouse movement and page scrolling should be enough to determine human user.

As the kind of person with technical knowledge to make a relevant decision, they fail to convince me that it is legit. So what if the page thinks I am human? If it is supposedly so accurate, how do I get to witness a failed case?

I do not know if they are marketing to nontechnical managers who force a decision on "Yes, boss" developers.

Next, what if I want to have a mobile app? How do I secure a sign up process there? (without reverting to a web form)

This is less "no more captchas" and more "Buy our captchas, they work, trust us."

That should set off everyone's bullshit detectors.

Looks shady. Image from their site [0] that is supposed to tell me that I'm human or bot is just a gif.
