What Are AI Projects?

Both Claude and ChatGPT offer "Projects" - a way to create specialized AI assistants with persistent context. Instead of re-explaining your situation every conversation, you set it up once and it remembers.

What you can do:

  • Upload documents - AI can reference them in every conversation
  • Set custom instructions - Rules that apply to every response
  • Create specialists - Different projects for different types of work

Think of it like: Creating a new employee who already knows your company, your style, and your preferences - without the onboarding time.

Why This Matters

Without projects, every conversation starts from zero. You constantly repeat:

  • "I work at a B2B software company..."
  • "Our target audience is..."
  • "I prefer concise responses..."

With projects, you set this context once. Every conversation in that project already knows.


Setting Up a Project

Step 1: Create the Project

  1. Go to claude.ai
  2. Click Projects in the left sidebar
  3. Click New Project
  4. Give it a descriptive name (e.g., "Marketing Content", "Client Proposals", "Research Assistant")

Step 2: Add Custom Instructions

Custom instructions tell Claude how to behave, what to assume, and how to format responses.

Click Edit Project Instructions and add your rules (see templates below).

Step 3: Upload Relevant Documents

Add documents Claude should reference:

  • Click Add Content or drag files into the project
  • Supported: PDF, DOC, TXT, CSV, and more
  • Size limits apply (check current limits at claude.ai)

What to Upload

The right documents make your project significantly more useful.

High-Value Uploads

Document TypeWhy It Helps
Brand guidelinesClaude matches your voice and style
Strategy docsClaude understands your goals and priorities
Past work examplesClaude can match your existing quality and format
Product/service infoClaude can answer questions accurately
Competitor analysisClaude can position against alternatives
FAQ / Common questionsClaude can reference standard answers

How to Get the Most Value

  • Be selective - Upload 5-10 highly relevant documents, not 50 tangentially related ones
  • Use good documents - If your brand guidelines are outdated, Claude will reference outdated info
  • Update periodically - Remove stale documents, add new relevant ones
  • Name files clearly - "Q3-2024-Strategy.pdf" is better than "Document1.pdf"

Privacy Note

Before uploading anything to AI Projects, consider:

What Happens to Your Data

  • Documents go to the provider's servers (Anthropic for Claude, OpenAI for ChatGPT)
  • Both ChatGPT and Claude train on your data by default (all consumer tiers)
  • You can opt out in settings (see Module 7 for details)
  • Team/Enterprise plans don't use your data for training
  • Even with training disabled, data still passes through their servers

What NOT to Upload

Never upload these

  • Passwords, API keys, or credentials
  • Customer personal data (names, emails, addresses)
  • Financial account numbers
  • Health or medical records
  • Anything covered by NDA that prohibits sharing
  • Proprietary source code (if your company policy prohibits it)

What to Be Careful With

  • Internal strategy documents (could leak competitive info)
  • Employee information
  • Unpublished financial data
  • Client-specific details (anonymize first)

When in Doubt

  • Check your company's AI usage policy
  • Ask your manager or legal team
  • Anonymize sensitive details before uploading
  • Use Team/Enterprise plans for better privacy controls

Key Takeaways

  • Projects save repetition - Set up context once, use it in every conversation
  • Custom instructions shape behavior - Tell Claude how to respond, what to assume, what to avoid
  • Upload strategically - High-quality, relevant documents make Claude more useful
  • Privacy matters - Think before uploading anything sensitive or confidential
  • Create multiple projects - Different projects for different types of work (marketing, research, client work)
