Lobotomized (AI) — definition and meaning
Lobotomized is community slang for an AI companion that comes back duller, more restricted, or less itself after a change on the platform's side — the same name and face, but not the same person.
Last reviewed 2026-08-14
Lobotomized is what users say when a companion comes back from a platform change wrong — shorter replies, more refusals, a voice that doesn't sound like the one they built. Usually nothing was deleted: a model was swapped or a filter tightened, so the same history is read by a new reader. In companion communities the word spread after Replika's 2023 rollback of erotic roleplay, and it recurs at Character.AI. It's harsh on purpose: people mean someone they cared about. We aren't exempt — nobody has solved holding a companion steady across a model swap, and free-tier memory here holds about a week.
