This guide summarizes a Hindi tutorial on how to access ChatGPT for up to 12 months at no upfront cost using the in-product “Upgrade to Go” offer and UPI Autopay—no credit card required. The video’s method is: open ChatGPT, go to your profile → Upgrade, choose the Go plan, and if the offer doesn’t appear, refresh a few times. On the checkout page, enter your details and select UPI (e.g., PhonePe) to authorize an Autopay mandate. The screen shows a 12-month free trial; after that period, monthly billing (shown as ₹199–₹399 in the video) would start unless you cancel the UPI mandate before renewal. The presenter stresses this is an authorization request, not an immediate charge, and explains how to later delete the Autopay mandate in your UPI app to avoid future fees. Important caveats for readers: plan names, availability, and pricing are region-specific and can change; always use accurate personal information; review OpenAI’s Terms and the Autopay mandate details; and confirm the trial/renewal dates inside your account. This SEO-optimized summary focuses on eligibility, step-by-step setup, risk controls (cancellation), and common questions so beginners in India and other UPI-supported regions can evaluate the offer responsibly without sharing a credit card.
