# Customize your AI agent: name, persona and models

> Name your agent, set its tone and reply length, route AI models by task with a cost cap, edit photos and get PDFs, Excel, Word and PowerPoint files in your brand kit.

Your agent is named by you and speaks the way you want. Pick its tone, how long its replies are and whether it uses emoji. Choose which AI model handles chat, planning, writing and browsing, with a fallback and a cost cap.

## Name and persona

Give it a name, a tone, a reply length and an emoji habit. It keeps that voice on every channel.

## Models by task

Route each kind of work to the model you trust for it, with automatic fallback and a monthly cost cap.

## Documents and photos

Quotes, sheets, documents and decks come back as PDF, Excel, Word or PowerPoint files in your language and brand kit. Every edit keeps a new version, and photos you send can be cropped, resized or cut out.
