heydecks is a Gamma alternative built around the complaint people leave Gamma over: PowerPoint exports that arrive as images or break on the way out. Where Gamma is a browser deck editor, heydecks is a REST API and an MCP server. Your agent sends a prompt and gets a live deck, a PDF, and a native, truly editable PowerPoint, each one locked to your brand by the Brand Kernel.

Why teams switch.
Exports you can actually edit
Every heydecks deck exports to a native PPTX with real text and shapes, plus a vector PDF. Gamma's most common complaint is exports that arrive as images or lose formatting once they are in PowerPoint.
Your agent builds it, not you
heydecks exposes a REST API and a hosted MCP server, so Claude or your own backend can generate a finished deck. Gamma is a manual, web-first editor with no deck-generation API to call.
Brand stays locked on every format
The Brand Kernel applies your colors, type, and logo to the live deck, the PDF, and the PPTX. There is no per-deck theme to re-pick and nothing drifts between formats.
