i-Digit is a captcha web service:

  1. Digitizing a physical-written document
    In other words, generating a digital text file (like .txt or .doc files) of a image of a paper containing text. Any book or journal containing appropriate content can be digitized.
  2. Protecting the web sites from bots and spams
    Any web site owner can register his/her domain to our i-Digit.Net system and embed our CAPTCHA to the web page wherever needed without any payment. By doing that you can both protect your web system from bots or spams and help digitizing old books or journals.
