Scan any question and Nuclei walks through it step by step. The reasoning comes first, the final answer last, so you actually learn it for the exam.
No matter the subject, Nuclei follows the same order, so the process stays predictable while you revise.
Photograph it, paste it, or type it in. Nuclei reads it and identifies what is actually being asked.
Each step is explained in plain language before moving to the next, so you can check your own logic against it.
The answer arrives last, once the working makes sense. Built for revision, not for submitting someone else's work.
Nuclei runs on tokens. Each time you solve a question, a small number of tokens is spent based on how detailed you want the walkthrough to be. That is it. No subscription, no monthly fee, no surprise charges.
Tokens sit in your account until you use them. Nothing expires, nothing auto-renews. If you don't solve anything, you don't spend anything.
