The Simsimi app offers many fun conversations to have on your iPhone and Android device, such as the one about the rapper Kanye West seen here. Twitter

Simsimi, the hottest iPhone, Android and iPad conversation app on the market, keeps on talking.

Despite being on the market for years, the Simsimi app's popularity remains high, as the artificial intelligence conversation program never seems to get boring.

Created in 2002 by the Korean tech company ISMaker, it uses artificial intelligence (or AI) to converse with human users.

The Simsimi app draws on a base of about 10 million question-and-answer conversations to provide an experience that many users describe as the best simulated conversations they have ever had.

When a user types a message to the Simsimi app on their iPhone, iPad or Android device, the app responds by scanning for related conversations in its massive database and spitting out a relevant--and often hilarious--response.

Simsimi users say it provides a experience much like one they might have with a quick-witted and lightning-fast human texting buddy, which should not come as a surprise because it is based in the knowledge of its 2.7 million users.

The experience of using Simsimi on an iPhone is explained in detail in a posting on

SimSimi is a super advanced chatting robot that makes amusing conversation to engage with users, the blog reports. Using this app is really simple. Just start a talk session at your touch screen then Simsimi will instantly greet you with a cheerful chat. Like those typical messaging apps, just send your message through a chatting box. Don't be surprised by Simsimi's fast response. It's a super-duper robot, you know!

The blog goes on to describe how the artificial intelligence built into Simsimi also allows it to learn new information from users, which allows the app, which the app calls the cutest chatting robot ever, to evolve over time:

Simsimi's vocabulary grows by your input. You can teach Simsimi your own words as other users teach their own ones too, the blog describes. If Simsimi has no data to answer your former message, it will say 'I HAVE NO RESPONSE'. Then you might select the 'TEACH' tab and instruct it your own words in a paired form of 'request & response'. Once you teach Simsimi a pair of words, it will make a response with those words immediately (approx. 3 minutes).

The Simsimi app for iPhone is often described as analogous to the conversation features that the Siri software on the iPhone 4s comes with, only unable to interact via a voice-recognition interface.

Though Simsimi can not do many of the things Siri is able to do--from fetching directions to setting an alarm--Jung-hoe Choi, the president of ISMaker, believes his Simsimi app is a superior conversationalist:

Contrary to Simsimi, Siri of iPhone seems to show the answer made by programmers, he told the blog.
