I'm Arun, the developer of Prompt Deck.

Problem

I change coding agents most weeks: Claude Code one day, Codex the next, Cursor when I'm working in the editor. 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.

That got messy fast. Finding a prompt from a few weeks back meant remembering which agent I'd used and then digging through its log files, and my CLAUDE.md or AGENTS.md files had drifted apart across projects.

So I built Prompt Deck. It's a native SwiftUI app that finds all of that on your disk and puts it in one window. Nothing to import, no account, and Prompt Deck itself only goes online to check your licence.

The parts I spent the most time on:

Prompts that become slash commands - write a prompt once, with {{variables}} you fill in when you use it, and install it as a real slash command in Claude Code, Codex, OpenCode, Antigravity CLI or Qwen Code. Every prompt keeps its version history, so you can compare two versions side by side and restore the one you want.

Every memory file in one list - global and per project, for every agent. Edit them in place, or append the same note to several projects at once.

Searchable session histories from these coding agents - Claude Code, Codex, Cursor, OpenCode, Antigravity CLI, GitHub Copilot, Qwen Code, DeepSeek Harness, Continue, Pi and Aider, searchable together. When an agent hands work to a sub-agent, that run opens right under the call that started it. One click resumes a session in your terminal.

Dreams (Pro only) - pick a memory file, say a project's CLAUDE.md, and a coding agent you already have installed, like Claude Code or Codex. Prompt Deck hands that agent your recent sessions and asks it to rewrite the file: keep the rules that still apply, update the ones your sessions show are out of date, and add what you keep repeating in chat. You get the result as a diff with a few notes on how you work, and nothing changes until you press Apply. It works on prompts too.

Insights (Pro only) - sessions per day for each agent, tokens in and out, your busiest projects, the tools and models you use most, the prompts you reuse, and a heatmap of when in the week you actually work.

Also, has a Command-K launcher that finds any prompt, session or memory file from any app, and exports sessions as Markdown or a web page.

Comparison

Claude Code History Viewer is free, open source, and reads more agents than Prompt Deck. It's a history browser, though: there's no prompt library and nothing for memory files. It's also built on Tauri, so the interface is a web view rather than a native Mac app.

Each agent's own resume picker (like /resume in Claude Code or codex resume) lists only that agent's sessions, and you can't search across tools.

Pricing

Free with no time limit: your 10 most recent sessions, 2 prompts and 2 memory files. Pro is $3.99/month or $29.99/year on up to 5 Mac accounts, and adds Pro features including Dreams, Insights, version history, export and sharing.

If you use a coding agent that isn't on the list, tell me about it, and I'll look at adding it in my application.
