Welcome to Arei.

Start using Arei right now

The web interface works immediately — no key needed. Ask your first question while your API key is on its way.

Step 1 — Signing in on another device

No password, no key to copy

The button above already signs you in on this device. On a different phone, browser, or computer, go to askarei.com, open "Account" above the question box, and enter the email you used at checkout — we'll send you a one-click sign-in link. Nothing to remember, nothing to paste.

Step 2 — API access (optional)

Want to build with Arei?

The API lets you send questions from your own apps, scripts, or workflows and get verified, multi-model answers back automatically. This is a bonus for developers — Step 1 above already gets you full access with no code. We'll also email your Arei API key to the address you used at checkout, usually within a few minutes, for this purpose. No email after 30 minutes? Email nonpareil.arei@gmail.com with your Stripe receipt and we'll send it immediately.

Paste this in your terminal. It sends a question to multiple AI providers at once — including Claude, now included on every paid plan — and returns a synthesized answer with per-sentence corroboration scores.

# Replace YOUR_API_KEY with the key we emailed you
