I change coding agents most weeks, and each one keeps its own memory file (CLAUDE.md, AGENTS.md, GEMINI.md) and stores its slash commands and chat history in a different folder and format. Prompt Deck is a native SwiftUI app that finds all of that on your disk and puts it in one window: prompts that become slash commands, every memory file in one list, and searchable sessions from 11 coding agents. Pro adds Dreams and Insights. Nothing to import, no account.
