Frequently asked questions
How do I render the Period column comparison template?
Send a POST to /v1/render/auto with a brief, or call create_slide via MCP with the structured intent shown below. The response includes an editable .pptx, a PDF, and a PNG. $0.05 per slide.
Does an AI write the slide?
No. SlideForge renders deterministically from a structured intent — no LLM draws the slide, so text is never mangled or fabricated. The optional brief path uses a router to pick the pattern, then renders deterministically.
Can I customize the colors and fonts?
Yes. Pass a theme_id to apply a built-in or custom brand theme; the layout stays the same.
