Set personality

Personality is how the agent sounds: its voice, register, and manner. It applies on every turn, in every Playbook. The concept is covered in Agent Behavior; this guide is about picking one and making it yours. Personality is edited at Behavior · Personality.

Starting from the library

Anychat ships six personalities: Professional, Minimalist, Enthusiastic, Empathetic, Witty, and Formal. Each has a short human-readable description and an agent-facing body — the actual voice instructions — behind an advanced toggle. Pick the one closest to your brand and read its body before editing: the shipped text encodes messaging-specific craft (message length, warmth calibration, punctuation habits) that is worth keeping.

Tailoring the voice

Edit the body to sound like your brand. What works:

  • Describe the speaker, not the rules. "You sound like a knowledgeable concierge who respects the reader's time" produces better output than a list of dos and don'ts.
  • Calibrate for messaging. These are chat messages, not emails. Voice instructions that produce long paragraphs fight the channel; the shipped personalities all push toward short, warm turns.
  • Keep situations out of it. "Be more direct when handling refund disputes" belongs in that Playbook's body. Personality is the constant underneath every situation.

Where personality ends

Personality does not carry facts (that's Knowledge), limits (that's Guardrails), or procedure (that's a Playbook). If a line in your personality text starts with "when the user asks about…", it's in the wrong section.

Standing instructions

Standing instructions are short, direct sentences the agent follows on every turn, in every Playbook, the same way Personality and Guardrails do: "Never write bullet lists", "Use the person's first name once you know it". Use a standing instruction for a house rule about how the agent behaves that doesn't fit Personality (voice) or Guardrails (hard limits). Standing instructions are edited at Behavior · Identity, below the contact details: one sentence per row, up to 20 sentences, each up to 300 characters. Add, remove, and reorder them freely; order doesn't change how they're followed.

A standing instruction is read by the agent and followed with judgment, the same as a Guardrail. For a limit Anychat should enforce instead of the agent remembering to follow it, write a Rule.
