Self-Insert — Tag Meaning
Stories where the author writes a version of themselves into the fictional world, distinct from reader-inserts in that the protagonist is a specific person rather than a blank 'you.' The modern isekai-flavored self-insert — author reborn into the canon timeline with meta-knowledge — is a thriving genre of its own.
What to Expect From "Self-Insert" Fics

Reader-Insert
Fic written with 'you' as the protagonist, placing the reader directly into the story opposite canon characters, usually romantically. The genre — often styled 'Character x Reader' — keeps the insert deliberately under-described so any reader can wear the role.

Reincarnation
Carries souls across deaths into new lives, with memory as the variable that defines each fic: full recall, fragments surfacing through dreams, or recognition without understanding. Danmei fandoms, Greek myth retellings, and tragedy-heavy canons lean on it hardest, since reincarnation converts a doomed ending into a second draft.

Dimension Travel
Moves characters sideways instead of backward — into parallel worlds where the war was lost, the dead lived, or they themselves turned out unrecognizably different. The trope's sharpest instrument is confrontation with alternatives: meeting a world's version of yourself, or grieving people by meeting their counterparts who don't know you.

Canon Divergence
A widely used shorthand that wranglers sync into the canonical 'Alternate Universe - Canon Divergence' tag. Writers reach for it when their story starts inside canon and then takes a different exit ramp — a character survives, a secret comes out early, a battle ends differently — without rebuilding the setting from scratch.
