Sound familiar?
You craft the perfect prompt. It works beautifully. Then you close the terminal.
You scroll through terminal history, but it's already gone.
You rewrite it from memory. It's never quite as good.
How it works
Install the CLI hook
One command connects Prompt Cellar to Claude Code, Codex, or Gemini.
Use AI like you always do
Every prompt is captured and encrypted before it leaves your machine. You change nothing about your workflow.
Find any prompt, instantly
Browse by session, search by keyword, filter by project. One click to copy.
Built for how you actually work
Session Timeline
Your prompts organized by coding session, project, and directory. Not a flat list—a timeline that mirrors how you actually work.
Encrypted Search
Search across every prompt you've ever written. The search index is encrypted client-side—we can't read your queries or your prompts.
One-Click Copy
Found the prompt you need? One click. It's on your clipboard. No modals, no friction.
Zero-Knowledge Encryption
Your prompts are encrypted with AES-256-GCM before they leave your browser. We literally cannot read them. Your key never touches our servers.
Built for paranoia
Your prompts contain your ideas, your code, your thinking. We designed Prompt Cellar so that even we can't see them.
Zero-knowledge architecture
AES-256-GCM encryption. Your master key is derived in your browser and never transmitted.
No analytics on your content
We see metadata: timestamps, prompt counts, session IDs. Never your actual prompts.
Free tier, no credit card
Try it with 100 prompts. No payment info, no commitment, no tricks.
