Theo Personality
Theo Personality is your per-account configuration — tone, persona, language, formatting preferences — that gets injected into every system prompt so Theo always sounds like the assistant you want.
In depth
Personality blends with Theo Memory but lives in user prefs and is bounded — name, pronouns, default language, default tone (concise / friendly / formal / playful), preferred output formats, and any always-on instructions.
It’s rendered into the system prompt for every entry point — web chat, Telegram, Theo Desk — so behavior stays consistent across surfaces.
Examples
- “Always answer in Spanish unless asked otherwise”
- “Default to concise outlines, then expand on request”
