Each file is saved in a dedicated folder for the new team member.
Analyze customer feedback and identify trends
This Cowork prompt mass-analyzes your customer feedback (reviews, tickets, NPS, emails) to extract actionable insights.

Run automatic competitive intelligence
This Cowork prompt leverages your intelligence files (screenshots, notes, articles) to produce a structured competitive report. Claude cross-references sources to build a comparison matrix, identify each competitor's recent moves, and propose prioritized strategic recommendations. The report is saved and can serve as a basis for strategic meetings.
Write a newsletter from my raw notes
This prompt transforms your raw research notes into a professional, structured newsletter. Cowork analyzes your raw files (notes, bookmarks, captures) to identify strong topics and organize them into engaging sections. The result includes A/B testable email subjects, commented curation, and closing CTAs to maximize engagement.
Generate a 30-day editorial calendar
This prompt analyzes your existing strategy documents to generate a coherent, actionable 30-day editorial calendar.

Results are saved in Markdown and CSV for easy tool integration.
Clean up and structure my Google Drive
This prompt uses Cowork to audit and restructure your cloud storage from a file export. Claude analyzes the existing folder tree, identifies issues (duplicates, orphan files, deep folders) and proposes a new structure tailored to your work. It also generates naming conventions and a detailed migration plan.
Prepare a complete meeting briefing
This prompt turns Claude Cowork into a meeting prep assistant. By analyzing your project folders, previous meeting notes, and documents, it generates a complete briefing: context, agenda, participant profiles, and strategic questions. Everything is based on your actual documents, not generalities. The briefing is saved as a file, ready for review.
