Example brief
Helios Grid, a regional energy utility operator, achieved significant improvements in outage communication. Customer callbacks decreased by 31%, status-update lag reduced from 46 minutes to 8 minutes, and first-contact resolution increased by 14 percentage points. These results were observed in the first 10 weeks after launching their operational dashboard, demonstrating the effectiveness of shared operational truth. The improvements had a positive impact on dispatch, field crews, and customer service, allowing them to work from the same live incident view for the first time.

Frequently asked questions
How do I render the Testimonial proof 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.
