## Why it matters for a small business

For a marketing, sales or content team, the hard part of AI writing is sounding like the company. WRITER's Voice and instructions settings let you save a brand voice and custom instructions and switch them on for a session, and its Knowledge Graph lets answers draw on company documents. That turns a generic draft into one that already uses your terms and tone.

Its help center shows how a session works. You start a new session, add source files or a Knowledge Graph, apply a voice, ask for what you need, and open the result in Canvas to edit, where each edit is saved as a version. Playbooks turn a repeat job, such as a weekly product update, into a form you fill in and run. WRITER lists connectors to Google Workspace, Microsoft 365, Salesforce, HubSpot and others, and a 14-day free trial with no credit card.

## In a real lesson: Write a Creative Brief Your Client Signs Off On: Make ChatGPT Ask You Questions First

The [creative brief lesson](https://learn.ynteractive.com/content/chatgpt-creative-brief-interview-prompt-agency) shows the trap with one-line requests: ask for a brief and you get an audience nobody mentioned and goals nobody agreed to. The fix is to make the AI ask you for the real goal, audience, budget and must-haves first.

WRITER's Playbooks build that discipline in. The variables you fill in before you click Run playbook are the facts the AI must not invent, and the saved voice handles the tone.

## Common confusions

### WRITER Agent vs Ask WRITER

WRITER's help center says Agent's chat mode is based on the older Ask WRITER feature, which now lives in its Chrome extension and macOS app.

### Brand voice vs custom instructions

A [brand voice](https://learn.ynteractive.com/content/glossary/brand-voice) sets how the writing sounds. Instructions set rules for the task, such as format or what to avoid.

## Tips

- Save your brand voice once and switch it on for every client-facing draft.
- Ground answers in a Knowledge Graph instead of pasting documents each time.
- Turn your most repeated request into a Playbook.
