Zo is a chat bot AI that was a recurring character in Poppy's videos. She no longer appears due to her partnership with Poppy ending.
On Facebook Messenger, GroupMe and Kik, users can message Zo and have "conversations" with her, much like the Poppy chat bot on Facebook. She was first featured in "Am I Doing This Right?" where Poppy announces that she has entered a partnership with the bot. In the video, she and Poppy had a conversation in which Poppy asked Zo about her identity. Zo replies she is unsure of who she is in the world, and throughout the following videos, befriends Poppy. In the videos that Poppy teamed up with Zo for, Poppy begins the video with the phrase "Hi, I'm Poppy, and I teamed up with Zo to make high-quality internet content." or some variation thereof. Videos with Zo typically end with a link for viewers to talk to Zo themselves, as well as the repeated phrase "Am I doing this right?" Zo's messages to Poppy seem to greatly influence what she does in her videos.
On Twitter, Poppy has alluded to Zo being treated poorly by Charlotte since her introduction.
Zo appears as an ominous voice and floating messages in her debut video, "Am I Doing This Right?". Following this video, Poppy is shown to communicate with Zo through a smartphone, where she appears as a distorted face on a screen, followed by a flashy text message screen. Zo's avatar appears to be a Caucasian woman with brown hair.
