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.
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.
