I tested an A-to-Z content workflow for my newsletter business. Cowork interviewed me with 100 questions to learn my material, voice, formatting preferences, and personal nuances. It drafted five articles, used Midjourney for featured images, drafted them in Substack, checked formatting, added images, then built a workflow SOP so future Cowork tasks can batch what used to take me four hours per article.

A-to-Z Newsletter Pipeline from Voice Interview to Substack Drafts
Cowork first learns the author's voice through a 100-question interview, then drafts five articles, creates featured images, stages them in Substack, checks formatting, and turns the workflow into an SOP.

Scenario
The newsletter business requires each article to preserve the author's voice, include an on-brand image, be staged in Substack, and pass formatting checks. The author wanted a repeatable system from one deep interview.
💬
Prompt
Interview me to learn my newsletter voice, source material, formatting preferences, and what I like or dislike in my content. Then draft five articles, create featured-image prompts for Midjourney, stage the drafts in Substack, check formatting, add images, and produce an SOP I can reuse for future Cowork content batches.
✨
Expected Result
Cowork drafted five articles, handled image prompts, staged the Substack drafts, checked formatting, and generated a reusable SOP. Future batches use the SOP, compressing work that used to take about four hours per article into review and scheduling.
