You’ve Solved Every Previous Year Paper.
So Why Does GATE Still Feel Uncertain?

Because solving is not the same as understanding. Retrieval is.

Recallivo turns any GATE textbook — CLRS, Galvin, Tanenbaum, Korth, Morris Mano — into a personalized question bank in 60 seconds. MCQs, flashcards, fill-in-the-blank. Built-in spaced repetition. Your book. Your gaps. Your schedule.

THE PROBLEM

The GATE Trap Nobody Talks About

You’ve worked through the standard books. You’ve solved the PYQs. You can follow every solution in the Made Easy booklet.

Then a novel question appears — a slight twist on a familiar concept — and you blank.

It’s not that you didn’t study hard enough. It’s that GATE tests conceptual depth, not surface familiarity. Solving the same PYQs repeatedly builds pattern recognition, not retrieval. You need to be able to pull the concept from memory and apply it fresh.

The candidates who score 800+ aren’t solving more PYQs. They understand their textbooks deeply and can retrieve concepts under pressure. That’s active recall + spaced repetition.

HOW IT WORKS

From PDF to Practice Questions in 60 Seconds

01

Upload Your Textbook

Drag and drop any PDF into Recallivo. A CLRS chapter on dynamic programming. A Galvin unit on memory management. Your annotated Tanenbaum. If it's a PDF, it works.

No reformatting. No copying. Just upload.

02

AI Generates Your Question Set

Recallivo reads your content and generates GATE-style MCQs, flashcards, fill-in-the-blank, and true/false questions — all built from your chapter, not a generic bank.

Questions reflect your exact edition, your annotations.

03

Review on a Spaced Repetition Schedule

Recallivo calculates when you're about to forget each concept and schedules it for review just before that point. You don't manage the schedule — you just show up and answer questions.

This is how you walk into GATE and actually retrieve under pressure.

TEXTBOOK EXAMPLES

Built for the Books You’re Already Using

Algorithms / DS

Introduction to Algorithms (CLRS)

CLRS is the definitive algorithms reference — but reading proofs and understanding algorithms is different from retrieving them under exam conditions. Upload any CLRS chapter and Recallivo generates questions that test algorithmic reasoning, complexity analysis, and problem identification.

MCQ

What is the time complexity of building a max-heap from an unsorted array of n elements using the heapify approach?

→ O(n) — linear time using bottom-up heapify, not O(n log n)

Flashcard

Master theorem: T(n) = aT(n/b) + f(n) — Case 1

→ If f(n) = O(n^(log_b a - ε)) for some ε > 0, then T(n) = Θ(n^(log_b a))

Fill-in

Dijkstra's algorithm fails when edge weights are _____ because _____.

→ Negative; it cannot correct already-finalized shortest path estimates

Operating Systems

Operating System Concepts (Galvin)

Galvin covers OS concepts with the depth GATE requires — but 900 pages of theory needs active recall to stick. Upload any Galvin chapter and Recallivo generates questions that test scheduling algorithms, deadlock conditions, memory management, and the conceptual nuances GATE loves to ask about.

MCQ

In Banker's algorithm, a system is in a safe state if there exists a sequence such that the resource needs of each process can be satisfied using currently available resources plus resources held by processes earlier in the sequence. How many such sequences may exist?

→ Multiple safe sequences may exist — safety is not unique to a single ordering

Flashcard

Conditions for deadlock

→ Mutual exclusion + Hold and wait + No preemption + Circular wait (all four must hold simultaneously)

True/False

In Round Robin scheduling, increasing the time quantum indefinitely approaches FCFS behaviour.

→ True — with infinite quantum, Round Robin degenerates to FCFS

Networks

Computer Networks (Tanenbaum)

Tanenbaum's Computer Networks is the authoritative GATE CN reference — but networking concepts require precise retrieval under pressure. Upload any chapter and Recallivo generates questions that test protocol behaviour, addressing, congestion control, and the layer-by-layer reasoning GATE examiners test.

MCQ

A network uses subnetting with a /26 mask. How many usable host addresses are available per subnet?

→ 62 — (2^6 - 2) = 62 usable hosts per subnet

Flashcard

TCP slow start vs congestion avoidance

→ Slow start: cwnd doubles each RTT until ssthresh; Congestion avoidance: cwnd increases by 1 MSS per RTT

Fill-in

The _____ protocol uses a three-way handshake: SYN, _____, and ACK.

→ TCP; SYN-ACK

COMPARISON

Why Not Just Use GATE Academy?

GATE Academy is excellent — we’re not here to replace it. But GATE Academy tests you on its questions, not the gaps in your understanding of your textbook. Recallivo fills the gap between learning and drilling.

STUDENT REVIEWS

What GATE Aspirants Are Saying

“

I uploaded the dynamic programming chapter from CLRS and had 35 questions in under a minute. Not just definition recall — actual algorithmic reasoning questions, which is what GATE tests.

— B.Tech CSE, GATE 2025 preparation, Bangalore
“

I was spending 3 hours a day building Anki cards for OS and CN. Switched to Recallivo and now I generate questions from exactly the Galvin chapter I just read. Night and day difference.

— Final year ECE, GATE CSE aspirant, Hyderabad

The Tanenbaum networking questions Recallivo generates are excellent. They force you to actually understand subnetting and protocol behaviour, not just recognise the terms.

FAQ

Frequently Asked Questions

Is Recallivo free for GATE preparation?

Yes. The free plan gives you 50 questions per month with no credit card required. Pro India is ₹399/month and includes unlimited question generation, all question types, and the full spaced repetition scheduler.

Can I upload CLRS, Galvin, or Tanenbaum directly?

Yes. Any PDF works — upload the full book or a single chapter. Recallivo generates GATE-style questions from exactly the content you upload.

How is Recallivo different from GATE Academy or Made Easy?

GATE Academy and Made Easy provide structured coaching and fixed question sets. Recallivo generates questions from your specific textbook — so the questions reflect exactly what you've been studying. They're complementary: Recallivo for mastering your textbooks, GATE Academy for exam-pattern practice.

What question types does Recallivo generate for GATE?

Recallivo generates GATE-style MCQs with explanations, flashcards, fill-in-the-blank, and true/false questions. All four formats are generated from a single upload.

How does the spaced repetition work?

Recallivo tracks which questions you answered correctly and which you struggled with. It schedules each concept for review at the optimal interval before you'd naturally forget it — based on the Ebbinghaus forgetting curve.

Does Recallivo work for GATE ECE and ME as well?

Yes. Upload any engineering textbook — Sedra/Smith for electronics, Cengel for thermodynamics — and Recallivo generates conceptual questions that test the deep understanding GATE requires.

How is Recallivo different from Anki?

Anki is powerful but requires you to manually create every flashcard — which takes 4-5 hours per chapter. Recallivo generates all question types automatically from your PDF in under 60 seconds.

Is my uploaded PDF kept private?

Yes. Your uploaded documents are private to your account and are not shared with other users or used for training without your consent.

Stop Reading. Start Retrieving.

You have the books. You have the dedication. The one thing between you and a top GATE rank is retrieval — and retrieval is a skill you build by practising it, repeatedly, on your own material, at the right intervals.
