He voiced two of the main characters in the popular Disney show, Grunkle Stan and Soos. He also voiced supporting and recurring characters such as: Old Man McGucket, Bill Cipher, the gnomes and many others. He has four siblings: his twin sister, Ariel Hirsch, his half-sisters, Lauren Hirsch, Katrina Hirsch, and Jessica Hirsch.
He placed many of his real-life experiences in the show, such as living in Piedmont, California and trick-or-treating with his sister Ariel as cats. He also based the series off the summers he and Ariel spent with their great aunt (or graunty) Lois, at her cabin in the woods, between the ages of 9 and 13. Both he and his sister wished they would go on the adventures that Mabel and Dipper go on in the show. He based Mabel on his twin sister, Ariel Hirsch, and Grunkle Stan off of his Grandpa Stan, and based the entire series loosely on his childhood summers. He gave Mabel a pet pig named Waddles because his sister had always wanted one when she was young.

Alex Hirsch was born and raised in Piedmont, California, and he graduated from the California Institute of the Arts (CalArts) in Los Angeles County, California, in 2007. He also enjoyed going to Oregon, and went there often. He was very fond of The Simpsons as a child, and cited this as one of his main influences. After watching the episode Bart's Comet he attended child therapy. Shortly after graduating, he worked at the digital entertainment studio JibJab and was a writer/storyboard artist on The Marvelous Misadventures of Flapjack. He also served as a creative consultant and helped develop the hit Disney Channel animated series, Fish Hooks, and voices the character Clamantha in the series. Hirsch chose Oregon as the setting for Gravity Falls after spending a summer there during college working for the animation studio Laika.
- In Spring 2007, he created a short film called Off the Wall, which was one of his student films at CalArts. Mike Moon, an animation executive at Disney eventually saw it. Impressed, he asked Alex to pitch the network a television series, which eventually led to Gravity Falls.
- He based Dipper off of himself.
- Hirsch has appeared a few times in the show as himself.

- Inside one of the sky trams in "Roadside Attraction," alonside Rob Renzetti.
- As one of the bodies in Bill's "throne of frozen agony," near the middle in Weirdmageddon 2: Escape From Reality.
- The reason for Alex Hirsch's many appearances is because the crew enjoys making fun of Hirsch by putting him in the show. This was revealed in "Between the Pines."
- Alex's college roommate was the show's art director, Ian Worrel.
- Alex guest voiced Officer Concord for the Phineas and Ferb Halloween episode called Terrifying Tri-State Trilogy of Terror.
- He has joked about the rumors that he is hiding occult symbols in the show on multiple occasions, because they are hidden in plain sight.
- Alex has a habit of tweeting misleading "Facts" to trick some fans for fun.
- Alex prefers Nintendo over Sega and his favorite Nintendo game is Kirby's Pinball Land.
- Alex named one of the Manotaurs after his full size adult taxidermy buffalo "Beardy" which he keeps in his office at Disney and insists people sit on when they take tours.
- The number 618 that appears throughout Gravity Falls is a reference to his birthday, June 18th (otherwise 6/18).
- He created the "McGucket Hoax" by leaking a fake photo of Old Man McGucket writing the Journals, which fooled a lot of people into thinking that Old Man McGucket was the Author of the Journals.
- Hirsch is skilled at bird calling and even went on the Late Show with David Letterman at the age of fifteen to share his talent.
- Hirsch has a set of rules regarding Dipper and Mabel's relationship which were created at the start of the series due to the writers frequently and incorrectly assuming that the two didn't get along. So far only two rules were revealed which were:
- The first rule is that "the kids like each other. no matter how much they get on each others nerves, this never changes."
- His Grandfather's ashes were illegally spread in a Vegas casino women's room so he could "see the ladies undress forever."
- He said in 2013 Comic Con panel that his favorite creatures from the series (season 1) are the Dipper clones.
- When Alex Hirsch was asked about what its like working for Disney, he answered that working for a gigantic company is like having 20 siblings sitting at one table and fighting for food. He explained that the main problem of working with Disney is that they have a lot of projects that are much bigger than Gravity Falls and they're often too busy making merchandise for those projects to pay attention to a small part of it like Gravity Falls.
- Alex Hirsch really loves to sleep. He didn’t sleep much for 4 years while he was making GF, but now he can enjoy sleep at its fullest.
- Alex has three to four flannel shirts. He started wearing them because he had a crush on a girl, but she didn't notice him until he went to a party dressed as the lumberjack mascot of "Brawny" paper towels. The costume was really ugly, but the girl of his dreams noticed him, and they started dating. Alex concluded that it must have been thanks to be the flannel jacket and started wearing it for luck. His family really hated the jacket and wanted him to burn it, so he promised to burn it if he ever made a TV show. After Gravity Falls came out, he, as promised, went to a desert and burned the jacket. But then he was cold, so he bought another one.
