JEE, NEET, UPSC, CAT — honest picks for doubt-solving, strategy, and the part no one talks about: the mental grind.
You won't use just one. Here's what each of these does best.
Exam prep is not one problem — it's four. Match the AI to the problem.

No single AI replaces a full JEE prep stack. For doubt-solving: Doubtnut and PhysicsWallah AI lead on JEE Mains/Advanced-level physics, chemistry, and maths. For study strategy, motivation, and the mental side (it's a grueling 18 months), Soriz Topper is the strongest companion. Many students stack: coaching material + a doubt-solving AI + Topper for the head game.
For NEET-UG (Biology, Physics, Chemistry), Doubtnut and Byju's AI cover question banks and video solutions well. PhysicsWallah's AI (Alakh) is strong for concept videos. Soriz Topper helps with NEET study planning, revision cycles, and the emotional grind — it's not a replacement for content, but it's the missing companion piece.
UPSC CSE is long (12-18 months), lonely, and information-heavy. ChatGPT and Gemini handle Prelims/Mains answer evaluation and current affairs summaries well. Soriz Topper helps with study schedules, daily discipline, revision strategy, and the isolation of self-study — UPSC aspirants often say the loneliness breaks them before the syllabus does.
Soriz Topper isn't a content bank — it won't replace your Aakash modules or PhysicsWallah videos. What it does: builds your study plan around JEE Mains dates, holds you to revision cycles, explains where you're stuck without spoon-feeding, and keeps you going when motivation drops. Think of it as the senior/topper-friend you wish you had.
Yes — Topper is included in the free Soriz tier with daily conversation limits. SorizPro (₹399/month, UPI supported) removes the daily cap and adds long-term memory so Topper remembers your subject-wise weaknesses and revision history across months.
Khanmigo is Khan Academy's tutor AI — global, strong for concept tutoring, free via Khan Academy India. It's excellent but not India-exam-specific. Soriz Topper is tuned for the Indian grind: JEE/NEET/UPSC/CAT pressure, coaching vs self-study dilemmas, and the parental-expectation weight that comes with it.
For CAT (MBA entrance), ChatGPT and Gemini handle VARC and Quant reasoning well. Soriz Topper helps with CAT study planning (alongside a job for working professionals), mock-test strategy, and not burning out before Jan when results drop.
Topper is free on Soriz. SorizPro (₹399/month, UPI) unlocks long-term memory so it remembers your weak areas across prep cycles.
