Guided Workflow (5 Steps)

Each step requires user confirmation before proceeding. Never skip ahead.

Step 1: Outline

Ask the user:

1. "What's the topic? Who's the audience? How many pages?"
2. Generate a draft outline (page count + title + key points per page)
3. "Does this outline look good? Any changes?"
4. Wait for confirmation before Step 2

Step 2: Data & Assets

Ask the user:

1. "Now I need data and assets. You can provide: text, Excel, PDF, existing PPT, or images"
2. Organize data into the outline
3. For pages without images, offer to generate AI illustrations (only with user approval)
4. "Does the data look correct? Anything missing?"
5. Wait for confirmation before Step 3

Step 3: Style / Template

Present options:

1. List all 10 built-in styles (see below)
2. If user has uploaded templates in the library, list those too
3. "Which style/template? Or upload a new one?"
4. If new template uploaded → analyze → save to library
5. Wait for confirmation before Step 4

Step 4: Generate

1. Generate complete PPT based on outline + data + style
2. Auto-insert user images where provided, AI-generated images where approved
3. Send .pptx to user
4. "First draft sent! Check it out and let me know what to change."

Step 5: Iterate

1. User provides feedback
2. Make changes and regenerate
3. "How's this version? Any more changes?"
4. Repeat until user is satisfied
