If you context-switch a lot—code reviews, emails, brainstorming, learning—you're retyping the same prompts all day. Works with Claude, ChatGPT, Gemini & Perplexity. PromptDeck fixes this. Save your prompts once, inject them with one click or Ctrl+Shift+P. Color-code them. Search. Pin favorites. Version history. 100% free. No login. Runs fully locally in your browser. Built this for myself after rewriting "Be a strict code reviewer" for the 50th time. Figured others might need it too.

Hi Folks👋

I'm Saksham, and PromptDeck is my first public launch.

The problem: I use ChatGPT and Claude for everything (debugging code, drafting emails, planning my week, learning new concepts), but these tools only support one static system instruction. Every time I switch contexts, I'm either retyping prompts or scrolling through old chats to find "that good one I used last week."

So I built PromptDeck. It's a Chrome extension that saves your system prompts and lets you inject them instantly across ChatGPT, Claude, Gemini, and Perplexity.

Features:
- Save unlimited custom prompts
- One-click injection (or Ctrl+Shift+P)
- Color-code and organize however you want
- Search and filter
- Pin your most-used ones
- Version history (roll back edits)

Everything runs locally in your browser. No account. No tracking. Free.

Also made a starter library with 70 prompts across different categories: https://promptdeck-library.verce...

This is v1. I'm sure there are bugs I haven't found yet. Open to all feedback.

Would love to hear how you're managing AI prompts currently, and what features would make this more useful for you.

Thanks for checking it out!
