[3] Primary development was handled by Headlock, and Dwango provided the world's infrastructure and Internet service.

[1] Before gameplay can begin, a player must download a client program unique to Ai Space which will enable its users to interact on the game's servers.

[6] Facial expressions, figures, and hairstyle among other things are customizable, and the player can even customize personal information like birthdays and blood type.

[9] The player can freely converse with their chara-doll in a manner similar to visual novels where the text appears in the lower portion of the computer screen.

According to Dwango's executive vice-president Toyoki Ōta, planning for the project began in 2006.

In 2006, Dwango was still primarily involved with the mobile phone industry, but were able to gain Internet service experience due to launching their subsidiary video sharing website Nico Nico Douga, which made it possible for Ai Space to move forward in development.

[2] Primary development was handled by Headlock which worked in collaboration with Key under Visual Art's, Navel with Omegavision, and Circus for the design of the bishōjo game heroines featured in Ai Space from Clannad, Shuffle!, and Da Capo II.

[5] Ai Space was initially going to be a text-based game similar to that of visual novels, but this was changed in favor of a 3D environment.

Despite an initial announcement of a Q3 2008 release of Ai Space's full version,[1] beta testing for the game was conducted in three separate phases between mid-September to mid-October 2008.
