Mongeau's most famous videos are her "storytime" videos. On February 10, 2017, Mongeau posted on her
Snapchat that she was being investigated by the
FBI after someone hacked into her emails and "sent a bombing and shooting threat to
McCarran International Airport." In November 2017, Mongeau was featured on a sketch posted to the
Maury YouTube channel. Her
MTV reality series titled
MTV No Filter: Tana Turns 21 premiered Summer 2019. Mongeau launched the
Cancelled podcast on July 26, 2021. Originally led by Mongeau, Hunter Moreno, and
Brooke Schofield, Moreno soon left the podcast, and currently Mongeau and Schofield host it together. The podcast covers pop culture as well as Mongeau's and Schofield's personal lives, often bringing in guests to provide their own thoughts and experiences. The podcast ended in 2025 after 130 episodes. On January 26, 2022, Mongeau launched her own wine brand Dizzy Wine.

Bella Thorne. Mongeau collaborated with
Lil Phag and Dr. Woke on a song titled "Deadahh" that was released on December 15, 2017. She released her second solo single, "W", on March 1, 2018. Her third solo single, "Fuck Up", was released on August 31, 2018. Mongeau's fourth solo single, "FaceTime", was released on May 18, 2019, alongside its music video.

Controversies "The N Word" On January 24, 2017, Mongeau posted a video titled "The
N Word" which has received over 7 million views. In the video, she describes an encounter where a person on her tour (later revealed to be YouTuber
iDubbbz) told her "
say nigger", in response to a tweet posted by Mongeau to iDubbbz, telling him to kill himself for his comedic use of the word in his YouTube videos. In May 2023, iDubbbz released a video apologizing for his past actions, which included a direct apology to Mongeau for his actions towards her.
TanaCon On May 26, 2018, Mongeau announced that she would be hosting her own convention, named TanaCon, from June 22 to 23, 2018, in
Anaheim, California. This was a reaction to
Vidcon 2017 organizers declining to give Mongeau the rights of a "featured creator" at their event. Mongeau scheduled TanaCon at the same time and in the same city as VidCon 2018, and intended her convention to be an alternative to it. TanaCon was organized in collaboration with actor and producer
Michael Weist. The convention began at the Anaheim Marriott Suites on June 22, but was canceled the same day. Over 80 creators were set to hold panels at the event, including
Bella Thorne,
Shane Dawson,
Casey Neistat,
Miranda Sings,
Ricky Dillon,
Elijah Daniel,
Jenn McAllister,
Gabbie Hanna,
Trevi Moran,
Lisa Schwartz, and
Jack Baran. Despite Mongeau's claims that 20,000 people tried to come to the convention – a number greater than the Marriott's capacity – only 4,000 to 5,000 attended. Those who attended or lined up to do so complained of a lack of food and water and of standing for hours in the sun. It was reported that many people were sunburned and that some passed out because of the heat. Mongeau later apologized and said that refunds would be issued. Shortly after TanaCon, Dawson released on YouTube a three-part documentary series examining the failure of the event. In May 2019, VidCon said that Mongeau would be a featured creator at the convention due to VidCon cofounder
Hank Green in 2018 having expressed regrets and stating that he had "100% screwed up" in not inviting Mongeau to VidCon 2017 as a featured creator.
Brooke Schofield Tweets In August 2024,
Cancelled co-host
Brooke Schofield came under fire for numerous screenshots of resurfaced tweets. A post depicting her thoughts on the killing of
Trayvon Martin in 2020 was at the center of controversy, reading, "Guarantee if Zimmerman shot a white guy this wouldn't even be a story. NEWS FLASH THIS WASN'T A CRIME OF RACISM IT WAS SELF DEFENSE". Mongeau called Schofield's posts "fucked-up" and "horrific", but she did not remove her as co-host. She also announced she would donate proceeds from the podcast and her TikTok content to the Trayvon Martin Foundation. ==Personal life==
