Copy Agent

Drafts subject + body in your brand voice. Used by the template editor's AI assist button and the Studio chat.

How it works

Given a prompt ("rewrite warmer, shorter CTA"), the current subject/body, and your workspace's saved brand voice (persona, tone, do-not-use list, examples), it returns a new subject + HTML body that respects the voice.

Trigger

• Template editor: "AI assist" button in /dashboard/templates/[slug]/edit.
• Studio chat:"Draft a new welcome email shorter and more casual" — the chat tool calls the Copy Agent under the hood.

Model

Claude Sonnet via Vercel AI Gateway. Cost is tracked per run in ai_runs.

Tips

• Fill out your brand voice in /studio/brand first — the agent is much more useful with a defined persona than a blank slate.
• For email-first drafts, ask explicitly for "inline-styled HTML, no <style> tags" — works around Gmail's CSS stripping.
