Your prompt is encoded with base64 and embedded directly in the URL fragment (the part after the #). When someone opens your link, the prompt is decoded entirely in their browser. No server ever sees, stores, or processes your prompt. The short URL is just a redirect to that encoded link — the prompt data never touches our database, only the redirect mapping does.

We literally cannot read your prompts. The prompt text lives in the URL hash, which browsers don't send to servers. We don't use cookies, analytics, tracking pixels, or any third-party scripts. There are no accounts, no emails, nothing to sign up for. The short link redirect is stored in Cloudflare KV with a 1-year expiry — after that, it's gone. That's the entire privacy policy.

Prompts are capped at 3,000 characters. Base64 encoding expands text by ~33%, and browsers start truncating URLs around 2,000–8,000 characters depending on the platform. We warn you at 1,500 characters and hard-cap at 3,000 to keep things reliable across all browsers and AI platforms.

Built by a human who got tired of re-pasting prompts across different AIs. RunPrompt is a free utility — no venture funding, no growth hacks, no plans to monetize your data (we don't have any). If you find a bug or have a feature idea, reach out on X @captnteebs.
