Example brief

The proposed plan for FY26 shifts spend from events to partner-led demand, with events decreasing from 24% to 14% and partner co-marketing increasing from 10% to 24%. Paid search decreases from 28% to 24% and paid social decreases from 22% to 18%. Content syndication increases from 9% to 12% and webinars increase from 7% to 8%. The reallocation is based on the conversion quality of partner-sourced opportunities, which converted 1.7x better in H1. The goal is to maintain total reach while optimizing the media mix.

Frequently asked questions

How do I render the Stacked composition bars 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.
