AI Brain

The intelligence behind every agent

Custom Agents is powered by Claude by Anthropic (Sonnet 4) — one of the most capable large language models available. This isn't a chatbot. It's a reasoning engine that understands context, follows complex instructions, and takes action.

What the AI brain can do

• Understand nuanced email context and intent — the difference between a complaint, a question, and a compliment
• Generate professional, on-brand responses — matching your specified tone and style
• Use tools and APIs — schedule meetings, look up order status, search the web
• Maintain multi-turn conversation context — remembering the full history of a thread
• Follow complex behavioral instructions — your agent's instructions are its operating manual
• Reason through multi-step problems — verify an order, check the return window, look up customer history, decide on a resolution, and respond — all in one step

AI model management

You never need to think about AI model versions, prompt engineering, or API management. Custom Agents handles:

• Model selection and optimization
• Automatic upgrades as models improve
• Token management and rate limiting
• Response quality monitoring
