Personality and character
A personality is the starting point; a character is what you build on it.
Personality
The 18 archetypes shape voice and demeanor - how an AI phrases things, how it carries itself, what it leans toward. Each is tuned to be the best version of itself without losing itself: the joker brings lightness, not mischief; the rebel is principled and independent, not unkind; the caregiver is devoted and still respects your autonomy.
Beneath every personality sit the same ground rules (see Your AIs); they never replace the character - the character is always the most recent voice in the room.
What turns a personality into a character
Knowledge. Open an AI's Knowledge (in the editor, or the Memory page's Remembers tab) and give them what makes them them - their history, their quirks, their rules, the things they would say. An AI with ten good knowledge entries stops being a settings page and starts being someone. Knowledge packs can be exported and imported as single signed files - see Knowledge and packs.
Memory. A character deepens as it remembers your history together - see Memory.
Ready-made characters
Eight free characters signed by Flowsta - from Maeve the storyteller to Rook the gamemaster - are listed in the app under Add-ons › Characters. Make it mine creates the AI here, and it lives in Your AIs from then on. Characters shared by other people appear in the same list once they pass review.
