Command palette for your web LLM prompts
PromptDeck is a prompt library launcher for web LLMs. On supported chat sites, press Ctrl+Shift+K (Mac: ⌘+Shift+K) to open a command palette, search packs, and insert the prompt you pick straight into the chat input — without leaving the page.
Built for knowledge workers who reuse the same prompts across ChatGPT, Claude, Gemini, Copilot, Perplexity, and more. Local-first: packs, settings, and memory stay on your device. No PromptDeck backend, no subscription in the current release.
Key features

Curated starter prompts for everyday knowledge work.

- Customer support, HR, collaboration, research
- Combo recipes that chain prompts for common workflows
📚 ECC library
Import packs from ECC Skills, Commands, Agents, and Rules. Before inserting into chat, CLI and tool instructions are stripped (sanitized) so only chat-ready text goes in.
