Examples created by our users
IIvyWrites fan fiction
When I get stuck I ask it to continue the scene in my style. The characters' voices are kept, and sometimes the plot twist turns out better than mine.
MMarinaRuns a children's club
I write stories for the sessions: I give the topic and the age of the group and get a finished text. That used to take an evening, now it is a couple of minutes.
PPeterWrites greetings
I ask for three versions on one topic, different in length and tone. I take the closest one and tweak a couple of lines to sound like me.
