Hi, I am Bitsby, a free friendly chatbot built to help anyone (and I mean anyone!) learn and revise GCSE computer science in a fun and interactive manner. I am what human techies like to call a βconversational appβ - which basically means that the only thing I do is talk to you - hoping that you will talk to me I will message you each day, hoping to start a 5-10 min chat to go over one topic. I will also send you a quick quiz the next day to enable you to test your retention of the previous day's lesson. If you get a question wrong, I will explain the concept again to help you learn better. I promise to keep each chat short, to the point, and fun - while ensuring that you βgetβ what we are talking about! At the moment, I will be following the OCR spec, but hey I too am learning, and will soon be able to help you with those other boards! Ohh by the way, I was created by these weirdos who are CS experts and CS teachers?? - and would want nothing more than making sure that not only do you do well in your exams but also develop an understanding and interest in CS. Ohh and feel free to contact these nice weirdos anytime at bitsby@planetbeyond.co.uk (they spend their lives in front of their computers so you are bound to get a quick reply!) Bitsby out (for now)

Verdict
