Q: Do my friends need to be on ChatChat for us to chat together?

A: Yes. To message each other and share agents in a group chat, everyone needs a ChatChat account, and they'll need to send you a friend request within the platform.

Q: Can I change what an agent does after I've already set it up?

A: Yes. You can expand an agent's role at any time by adding new skills, integrations, schedules, or Living Brain access, similar to how a role might grow at work. You can also update the agent’s core instructions, voice, profile, and other available settings after creation.

Q: Can one ChatChat account manage multiple agents for different areas of my life or business?

A: Yes. Most people run a small team of specialised agents rather than one general assistant, for example a Chief of Staff agent, a Social Media agent, and a Personal Trainer agent, each with access only to what it needs.

Q: Do agents support voice, or just text?

A: Agents support voice conversations with a configurable voice for each one. You can also call an agent directly.

Q: How do agent instructions, the Living Brain, prompts, skills and connectors work together?

A: Agent instructions define the agent’s durable role, behaviour and boundaries. The Living Brain stores persistent facts, sources, history and decisions. The task prompt explains what the agent should do now. Skills provide repeatable methods for completing work, while connectors provide authorised access to external tools and data.

Q: How can I write a better prompt?

A: Include six elements: the desired outcome, relevant context, sources to use, constraints or escalation rules, required output format, and how the result should be verified. For example: “Using my Sales Brain, HubSpot and the last 30 days of meeting notes, prepare a one-page briefing for tomorrow’s client call. Include relationship history, open actions, risks and five questions. Cite the source for every factual claim. Do not send anything.”

Q: How do I teach an agent to perform better over time?

A: Put stable role expectations in the agent instructions, durable facts and decisions in the Living Brain, and task-specific requirements in the current prompt. Give explicit feedback about what was right, wrong or missing. If the same problem occurs in a scheduled workflow, update the scheduled-task prompt. Remove stale or contradictory context rather than continuously adding more instructions.

Q: Where can I find available skills?

A: Browse the Skills marketplace inside ChatChat. Skills cover areas such as documents, productivity, development, business, research, health and creative work. The live marketplace is the source of truth because the available catalogue can change.
