Create a weekly summary of my activities
This prompt leverages Cowork's ability to read and analyze your local files to compile an automatic weekly review. By scanning your notes, projects, and task files, Claude produces a structured summary with productivity metrics, project progress, and pending tasks. The result is saved directly as Markdown, ready to share with your team or archive.
Organize and rank job applications
This Cowork prompt analyzes every CV and cover letter in your applications folder. Claude evaluates each candidate on 5 weighted criteria, generates an overall score, summary, and ranking. The shortlist is argued with points to explore in interviews. Email templates (acceptance and rejection) are included for a complete recruitment process.
Sort and organize my Downloads folder
This Cowork prompt turns your messy Downloads folder into a clean, date-organized file structure. Claude directly accesses your files, identifies types, spots duplicates, and proposes a smart sorting plan. Each file is renamed with its modification date for chronological ordering. The process is safe: no deletion without your explicit approval. Perfect for a one-time cleanup or monthly routine.
Automate invoice generation
This Cowork prompt automates invoice generation from your service data (CSV, spreadsheet). Claude applies legal mentions, calculates VAT and totals, numbers sequentially, and saves each invoice in your file structure. The global summary and payment tracking update complete the billing process.
Analyze a CSV file and generate a dashboard
This Cowork prompt transforms any CSV file into a structured analysis. Claude explores the data, cleans it, applies relevant analyses based on detected data type (sales, customers, marketing) and generates actionable insights. The report includes statistics, trends, and recommendations. Multiple exports (Markdown, cleaned CSV, JSON) facilitate follow-up work.
Analyze my website's SEO performance
This Cowork prompt transforms your raw Google Search Console exports into a structured, actionable SEO audit. Claude identifies quick-wins (pages in position 5-20 to optimize), problems (cannibalization, declining pages) and generates recommendations prioritized by impact and effort. The CSV tracking table enables continuous monitoring.
Create a pitch deck from my business plan
This Cowork prompt analyzes your business plan and condenses it into a 12-slide pitch deck ready for design. Claude extracts key data (market, traction, financials) and structures it in standard investor format. Each slide includes text content, talking points, and visual suggestions.
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.
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.
Build a tech watch system
This Cowork prompt structures your tech watch by analyzing your scattered sources (saved articles, notes, newsletters, bookmarks). Claude identifies strong trends and weak signals, evaluates emerging tools, and checks updates for your tech stack. The personalized training plan helps prioritize your skill development.
Prepare a monthly financial report
This Cowork prompt generates a professional financial report from your accounting files (bank exports, invoices, tracking spreadsheets). Claude analyzes data, calculates KPIs, compares with previous month, and flags alerts. M+1 projections help with planning. Ideal for freelancers, small businesses, and startups without a CFO.
