Draft from what you've already approved.
Your brand voice, past campaigns and approved messaging shouldn't live only in a style guide nobody opens. Keep them within reach of every draft.
Start free →The work you know
Every new draft starts by hunting for the last good one.
A launch announcement needs to sound like the last three. The approved claims are in one document, the voice guidelines in another and the best-performing campaign in a folder someone left.
ContextStream keeps your guidelines, campaigns and messaging together. Save your brand voice once and ask for a draft in Claude, ChatGPT or the web app, with the source of every claim it leans on.
A typical workflow
Draft a launch announcement in your brand voice.
Start from what you've already approved, not from a blank page.
Bring in your guidelines and campaigns
Connect the place your brand documents live, or import notes from past campaigns.
Save your brand voice
Describe how you write: tone, words you use and words you avoid. Every draft follows it.
Ask for a draft
Ask for an announcement and check it against the messaging it drew on. Share the voice with an agency as a briefing.
