"I, Robot...You, Jane" is the eighth episode of season 1 of the television series Buffy the Vampire Slayer. The episode was written by staff writers Ashley Gable and Thomas A. Swyden, and directed by Stephen Posey. The episode originally aired on The WB on April 28, 1997.

In this episode, Buffy and Giles face a demon spirit who has been trapped since the Dark Ages and is unleashed into cyberspace. Meanwhile, Willow has fallen for a cyber-beau whom she met online and Xander and Buffy are wary of who this anonymous wooer may turn out to be.

In Cortona, Italy, in 1418, a circle of priests trap a horned demon (Moloch "the Corruptor") in a book using a magic ritual. The book is sealed in a box, with the head priest expressing the hope that the book will never be read, lest the demon be released upon the world. In the present, the book is delivered to Giles and added to a pile that Willow is scanning into a computer.

Willow tells Buffy that she has formed an online relationship with a boy named Malcolm. As Buffy tries to warn Willow about the dangers of rushing into a relationship with someone she has not seen, Fritz, a geeky student, is instructed by Moloch, via the computer he is working on, to keep watch on Buffy. Later, when Xander asks Willow if she will accompany him to the Bronze, she passes, preferring to talk to Malcolm. When Willow arrives late the next day, Buffy finds that she missed classes to talk to "Malcolm". Suspecting that Malcolm might be catfishing Willow, Buffy asks Dave for help in finding out Malcolm's real identity, but his angry response causes her to suspect that he is Malcolm. When Buffy asks Giles for help, he confesses he cannot help her much as he finds technology to be intimidating.

Willow becomes suspicious of Malcolm after she learns that he knows Buffy was kicked out of her old school, and logs off the conversation. Back at the library, Giles discovers that Moloch's book is blank. He realizes that when Willow had scanned the book, the Corruptor had been loosed into the internet.

Outside of school, Dave tells Buffy that Willow wants to talk to her in the girls' locker room. At the last minute, Dave has a change of heart and warns Buffy that she is about to be electrocuted. In the library, Giles tells Buffy and Xander that demons can be imprisoned in books; if the books are read aloud, the demons are set free. Giles also explains that Moloch is an extremely powerful and seductive demon, winning his victims over with false promises of love, glory and power. Buffy and Giles realize that there is no limit to the destruction that a demon could do through the Internet.

After they find Dave's body, an apparent suicide, Xander and Buffy go to Willow's house; but she is not there. Buffy tells Giles to ask the computer teacher Jenny Calendar for help, hoping that between his knowledge of demons and her knowledge of computers, they can re-imprison Moloch. Willow has been kidnapped by Fritz and taken to a defunct computer company where a team of technicians and programmers has built Moloch a robot body that looks like the one on the cover of the book in which he had been imprisoned.

Giles seeks help from Jenny, and is surprised that she is already aware of the demon in the Internet. They cast a binding spell via computer, but it does not go as planned. Moloch is yanked out of the internet but into his robotic body, not back into the Moloch book as Giles had expected.
