heydecks vs SlideSpeak
The SlideSpeak alternative for developers
SlideSpeak turns a prompt into a PowerPoint. heydecks adds a structured deck store, a hosted MCP server, and a Brand Kernel, so agents build and edit real decks, not one-shot files.
heydecks is a SlideSpeak alternative for developers who want more than prompt-to-PPTX. It stores each deck as structured, typed slides an agent can build and edit over a REST API or a hosted MCP server, then exports a live link, a PDF, and a native PowerPoint, every one locked to your brand by the Brand Kernel.
heydecks vs SlideSpeak.
| heydecks | SlideSpeak | |
|---|---|---|
| Deck model | Structured, typed slides you can edit | Prompt to a generated PowerPoint |
| Agent access | Hosted MCP server plus REST API | API focused on generating files |
| Brand control | Brand Kernel locked on every export | Templates applied at generation time |
| Editing after generation | Update individual slides over the API or MCP | Regenerate or edit the exported file |
| Output | Live link, PDF, native PPTX | PowerPoint and PDF export |
Why teams switch.
Decks are data, not one-shot files
heydecks keeps each deck as structured, typed slides, so an agent can add, reorder, or rewrite a single slide later. SlideSpeak is centered on generating a finished file you then edit outside the tool.
A hosted MCP server, not just an API
Connect heydecks to Claude, Claude Code, or Cursor over MCP and the agent drives the whole flow. You get an agent-native surface, not only a file-generation endpoint.
Brand lock is built in
Extract your brand once and the Brand Kernel applies it to every deck and every export. Branding is part of the platform, not a template you re-select per generation.
