Save this OpenAI key?

OpenAI production

Dismiss Save

Zero-friction saving

When you generate a new key, a prompt appears to save it with an auto-detected name and provider.

Works with your providers

Tested against Stripe, OpenAI, Anthropic, SendGrid, Twilio, Supabase, and the AWS console.

Minimal permissions

No access to your passwords or browsing history. It only scans the DOM for API key patterns.

Encrypted sync (Pro)

Carry your keys across devices with end-to-end encrypted sync — the server never sees the key in plaintext.

FAQ

Everything you want to know

It's a tool that stores your API keys encrypted and autofills them when you need them, so you don't have to copy-paste manually every time or lose them if you never wrote them down.

Yes, the Free plan lets you save up to 10 API keys at no cost and no credit card. Pro adds unlimited keys and encrypted sync across devices for $5/month.
