Others
Gamma, SlidesAI, and Beautiful.ai do not support direct file conversion — they only generate slides from text input. If you need to convert existing documents, they require you to copy-paste content manually.
Best Practices for Document Conversion
- Use text-based PDFs — scanned documents need OCR first
- Add conversion prompts — "focus on key findings" gets better results than no prompt
- Choose the right theme — data-heavy docs → McKinsey theme; narrative docs → Apple theme
- Review and iterate — AI gets 90% right; spend 5 minutes on final touches
- Automate recurring conversions — use the API for weekly/monthly report slides
