A Copywriter fellow is not a prompt template with your company name pasted in. It is custom-built around your brand. We start by scoping the role with you — your style guide, your past content archive, your voice, your audience, your channels, and what you never want to sound like.
By the time River joins your Slack, it has read your blog archive, your best-performing emails, your social posts, and your ad copy. It knows the difference between your LinkedIn voice and your email voice. It knows which phrases your brand uses and which ones it avoids.
The generic AI writer guesses at your voice from a one-line prompt. River has read your archive and writes like your best day, every day.

Yes. We train River on your archive — past blog posts, ads, social, emails. Voice consistency improves over the first month as you give feedback in Slack.
Voice is our wedge. The fellow is trained on your specific archive and tone, not on a generic 'marketing voice'. Output quality depends on the source material we train on; teams with strong, distinctive past content get better results faster.
We connect the fellow to the tools the role uses. Statamic, WordPress, Webflow, HubSpot, Notion — whatever you publish to.
