The Twilight star is one of 12 female creatives making films for women-focused media company Refinery29.
Fellow actresses Gabourey Sidibe and Chloe Sevigny will join Stewart under the umbrella of Refinery29's ShatterBox Anthology.
Oscar nominee Sidibe will direct her own short film titled A Tale of Four Women, according to Variety.
Meanwhile, Sevigny's Kitty, the first film of the anthology, will premiere at Cannes Film Festival later this month.
Speaking during Refinery29's presentation at the Digital Content NewFronts event in New York, Sidibe said it was important to tell a story through her own voice.
She said: "[In my acting career] everything I do, my image and who I am and what I feel represents me is in the hands of a man, usually a white man... I realised very recently that I want to be the one that decides what image I show the public."
It was also announced that Ugly Betty star America Ferrera will produce a multimedia project titled Behind the Headlines, and a documentary series titled Only Girl.

It will be the 20-year-old's second spell at the club, having joined on loan from Rochdale in 2016.

Peter Atilla, 46, from Northampton, said he had a sleep condition called sexsomnia.
Mr Atilla was accused of having sex with a woman while she slept after she invited him in bed "for a cuddle".
Methyr Tydfil Crown Court heard he had returned from a tour of Afghanistan the day before, and may have been in "action mode" when he went to sleep.
Two psychiatrists told the court it was "possible" the defendant suffered from parasomnia - defined as unwanted behaviour during sleep.
Dr Chris Idzikowski said a subset of parasomnia was sexsomnia - a type of "confusional arousal" - which can lead to sexual behaviour from a person in deep sleep.
Dr Idzikowski said: "If he arrived back in action mode it's potentially something that would come through in his sleep.
He said Mr Atilla, a former Royal Logistics Corps officer who served "with distinction" in the first Gulf War, Kosovo, Iraq and Afghanistan, may have been triggered by something as simple as a sound.
He admitted the evidence the disorder led to Mr Atilla having sex with the woman while asleep was "weak" but said he could not exclude it from being possible.
Another psychiatrist, Dr Chandan Seghal, said he too "could not exclude" the attack relating to a sleep disorder, but agreed the evidence was "weak."
Mr Atilla told the court he had "no memory" of the alleged incident.
