Why Prompt Structure Matters for DeckEdit
DeckEdit creates a separate text box for each block of text it detects on a slide. If your AI-generated slides are cluttered or poorly organized, the OCR engine may merge overlapping regions or produce phantom text boxes in the final PowerPoint file.
The fix is simple: prompt NotebookLM to produce slides with clean, modular layouts before you convert them. A few small changes in your prompt can dramatically improve the quality of the editable output.
3 Prompting Tips for Better Slides
Use words like "bullet points," "distinct sections," or "labeled diagrams." This helps the OCR engine separate headers from body text and recognize each element individually.
AI slides often get cluttered. Add a constraint like: "Create a 10-slide presentation with no more than 50 words per slide." This prevents DeckEdit from producing overlapping text boxes.
Tell the AI to use "bold headers and distinct sub-points." DeckEdit's engine picks up on size differences to format your PowerPoint export more accurately, assigning correct heading levels and font sizes.
The "Clean Slide" Prompt Template

The "Investor-Ready" Business Pitch
Investors prioritize clarity over decoration, looking for slides that can be scanned in under 3 minutes. This prompt follows the structure used by major accelerators.
Why it works for DeckEdit:
- One Idea Per Slide: Prevents the OCR from cramming multiple text boxes into a single region in your PowerPoint export.
- White Space Placeholders: Ensures you have a clean area in the final PPT to drop in your own data-led visuals.
The "Mastery-Focused" Study Guide
Educational slides benefit from minimalism and strong hierarchies to aid retention. This prompt synthesizes complex research into a teachable format.
Why it works for DeckEdit:
- Standardized Bullet Counts: Following a consistent structure (1 idea, 6 bullets, 6 words per bullet) ensures text remains readable even on mobile devices.
- Clear Title Hierarchy: Each slide has a distinct bold title that DeckEdit recognizes as a heading-level element, resulting in properly formatted PowerPoint text boxes.
Optimization Tips for DeckEdit Success
| Guideline | Core Logic | Benefit for DeckEdit |
|---|---|---|
| 1-6-6 Rule | 1 idea, 6 bullets, 6 words per bullet | Prevents text-heavy boxes that reduce OCR accuracy. |
| 10/20/30 Rule | 10 slides, 20 minutes, 30pt font | Ensures headers are large enough to be identified as title elements. |
| Modular Layout | Distinct sections and headers | Creates separate, draggable text boxes in the final PPTX. |
Even though NotebookLM added a native PPTX export in February 2026, using these prompts still produces more professional layouts that require less manual adjustment in PowerPoint.
Why This Helps DeckEdit
Well-structured prompts prevent "phantom" text boxes from appearing in your PowerPoint. Each text element maps cleanly to one editable box.
The OCR engine aligns text more naturally when the original PDF has breathing room between elements. Crowded slides produce misaligned boxes.
You will spend less time dragging boxes around in PowerPoint once the conversion is done. Clean input produces clean output.
