What is reCAPTCHA?
reCAPTCHA is a CAPTCHA system that enables web hosts to distinguish between human and automated access to websites. The latest version aims to have as little user interaction as possible, using machine learning to analyse a user's actions and determine if they are a bot, and if they fail that test they are asked to identify typically road-related items, which can help both to identify humans and train Google's self driving car project.
The original version asked users to decipher hard to read text or match images. Version 2 also asked users to decipher text or match images if the analysis of cookies and canvas rendering suggested the page was being downloaded automatically. Since version 3, reCAPTCHA will never interrupt users and is intended to run automatically when users load pages or click buttons. reCAPTCHA is owned by Google.
The original iteration of the service was a mass collaboration platform designed for the digitization of books, particularly those that were too illegible to be scanned by computers. The verification prompts utilized pairs of words from scanned pages, with one known word used as a control for verification, and the second used to crowdsource the reading of an uncertain word. reCAPTCHA was originally developed by Luis von Ahn, David Abraham, Manuel Blum, Michael Crawford, Ben Maurer, Colin McMillen, and Edison Tan at Carnegie Mellon University's main Pittsburgh campus. It was acquired by Google in September 2009. The system helped to digitize the archives of The New York Times, and was subsequently used by Google Books for similar purposes.
The system is free for 1 million calls monthly, and $1 per 1,000 after that (up to 10,000,000).

Maybe the most popular, but far from being the better tho.
there are also some darkweb services to bypass it which I now pay for on some sites I use more often.

Useless against bots. Disguised User Tracking.
Making humans 'prove' they aren't robots by forcing them to act like robots, so that the real robots could use the data to become more human-like. For your own protection, I might add!
Might have worked circa 2005 but is complete garbage today. Don't waste your time.
A horrible and privacy intrusive solution blocking common users and making users work for Google.
An example of technical monopoly where there are very few other viable and privacy friendly solutions.
