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

1

Install the CLI hook

One command connects Prompt Cellar to Claude Code, Codex, or Gemini.

2

Use AI like you always do

Every prompt is captured and encrypted before it leaves your machine. You change nothing about your workflow.

3

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.
