The Sega AI Computer (AIセガコンピュータ) is an extremely rare computer released in Japan by Sega in 1986. The unit was seen to be ahead of its time upon release, though did not sell in large numbers. Plans were put in place to bring this system to North America in 1987 under the new name of SEGA DI 8300, but this never materialised.

The Sega AI Computer features a number of different modules including a keyboard for programming, a graphics tablet, a speech recognition device and a music composer. It runs software stored on Sega Cards, physically identical to those used in the SG-1000 II, Sega Mark III and the original model of the Sega Master System, though is not compatible with any of those systems.

The computer's software released from 1986 to 1988, and includes educational games.[2]

In July 1986, Sega announced the world's first home computer equipped with AI (artificial intelligence), intended for the household and consumer markets.[3][4][5]

A first auction sighting of a Sega AI Computer in 2004 valued the item at £19000. In 2014 one was sold on Yahoo Auctions for 124200 JPY (about $1100) and 15 software were auctioned separately.

The only other computer manufactured by Sega was the SC-3000, released in 1983. Sega also previously previously released a tablet controller, the Sega Graphic Board, in 1985.
