What Does Self-Insert Mean?
Fic TypeA fic where the author writes a version of themselves into the story's world, interacting with canon characters. Sometimes thinly disguised as an OC; sometimes proudly undisguised.
Self-Insert in Practice
The self-insert is probably fanfiction's primal form — the daydream of stepping into the story, written down — and fandom's attitude toward it has completed a full arc: early internet fandom mocked it mercilessly as Mary Sue territory, and the modern era has substantially reclaimed it, treating self-insert work (and the adjacent self-ship culture) as honest, joyful wish fulfillment. Conventions distinguish degrees: a literal self-insert uses the author themselves, while many 'SI' protagonists are idealized or anonymized stand-ins. The genre also includes the isekai-flavored variant where a modern person wakes up inside the canon world. Reader-inserts differ by aiming the fantasy at the audience instead of the author.
Example usage
"It's an unapologetic self-insert isekai where the author wakes up in the game world, and it's genuinely delightful."
