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

1. Use text-based PDFs — scanned documents need OCR first
2. Add conversion prompts — "focus on key findings" gets better results than no prompt
3. Choose the right theme — data-heavy docs → McKinsey theme; narrative docs → Apple theme
4. Review and iterate — AI gets 90% right; spend 5 minutes on final touches
5. Automate recurring conversions — use the API for weekly/monthly report slides

For financial documents specifically — 10-Ks, earnings releases, portfolio exports — a document-to-deck converter formats what's already on the page, but it can't refresh the numbers. PickSkill is a finance-specialist agent that pulls live market data and SEC filings, runs the analysis, and exports a sourced investment-research .pptx where every chart reflects the latest close.
