It costs nothing to start — a real free tier, not a trial that dies in a week. Sign-in is by X account or email, so an X login is the fastest way in.
The free tier works on a usage pool: you get an allowance, spend it, and it refills on its own schedule. The exact numbers change often, so treat the mechanism as the durable fact — you will hit a wall, and the wall lifts by itself.
A few questions and some writing a day costs nothing. You'll feel the limits if you run long research sessions, lean on it daily for work, or make a lot of images — image generation burns an allowance far faster than chatting. Grok is a standalone app (web/iOS/Android). Since 12 October 2026, new customers sign up through The X Subscription — not only as an X Premium+ perk — and existing SuperGrok plans continue for current subscribers unless they switch. Beyond the free plan, The X Subscription runs from Plus at $8/month up through Premium, Super and Ultra, each with more usage. Grok Bot is a separate product and a separate catalog page.
