How to Use AI to Create an Explainer Video for Any Exam Question in 2026

If you have ever sat in front of a past exam paper at midnight, stuck on a problem you cannot crack, you know the gap that has existed forever in test prep: a static answer key tells you what the answer is, but not how someone gets there. Watching a tutor work through it on a whiteboard is the gold standard — and until recently, the only way to get one was to pay for one.

That changed in 2026. You can now take a screenshot of any exam question — JEE, SAT, AP, GRE, GMAT, AIME, a homework problem, a textbook exercise — drop it into an AI video tool, and get back a fully narrated whiteboard explainer with the worked solution and the final answer choice at the end. The whole thing takes about as long as making a cup of coffee.

This guide walks through the exact workflow using a real example: IIT JEE Advanced 2025 (Main paper), Math section, Question 5.

The Old Way vs. The New Way

Here is what solving a tough exam problem used to look like for most students:

• Option 1 — Answer key: Look up the final answer. Useless if you do not understand the steps.
• Option 2 — YouTube search: Hope someone has already made a video for that exact question. Often they have not, especially for newer papers or less common exams.
• Option 3 — Pay a tutor: The best outcome, also the most expensive and the slowest to schedule.
• Option 4 — Read a forum thread: A wall of text from anonymous strangers, sometimes contradicting each other.

Here is what it looks like in 2026 with an AI video tool like Golpo:

• Step 1: Screenshot the question (or photograph it from a book).
• Step 2: Upload it to Golpo and ask the AI to solve and explain it.
• Step 3: A few minutes later, watch a custom whiteboard explainer video built specifically for that one question, ending with the correct answer choice.

That is the entire workflow. No searching, no scheduling, no payment per question, no hoping someone on the internet has already covered it.

The Example: IIT JEE Advanced 2025 Math, Question 5

The IIT JEE Advanced is one of the toughest entrance exams in the world. Over a million students attempt the qualifying round each year in India, and only a fraction clear it. Question 5 of the 2025 Math section (Main paper) is a multi-part vector geometry problem involving a line of intersection of two planes, a parallel line through a given point, and the foot of a perpendicular — exactly the kind of problem where a static answer key is useless and a worked walkthrough is everything.

Here is the question, exactly as it appeared on the paper:

The problem asks you to verify which of four statements about lengths, areas, and angles in the resulting geometric figure are true. To solve it manually, you need to find the direction vector of the line of intersection (a cross product), parametrise the second line, intersect it with the plane, project a point onto the plane, and then compute lengths, an area, and an angle. That is a lot of steps, a lot of opportunities to make an arithmetic mistake, and a lot of dense vector algebra to keep track of.

The Output: A Fresh Explainer Video in Minutes

Here is the video Golpo generated from that single screenshot. Notice that the AI works through every step on the whiteboard — setting up the vectors, doing the cross product, parametrising the line, finding the intersection, projecting the perpendicular foot, computing the area of the triangle, and finally arriving at the correct answer choice at the end of the video.

A few things worth pointing out about this video:

• It actually solves the problem. The AI does not just describe the question — it works through the algebra, computes the values, and tells you which of the four answer choices are correct.
• It uses the whiteboard format. Equations get written out by a hand-drawn pen as the narrator explains each step, which is exactly how a tutor would teach this on a blackboard.
• It ends with the answer. The final segment explicitly states which options (A, B, C, D) are true, so you never have to guess what the AI concluded.
• It was generated from one screenshot. No re-typing the problem, no LaTeX, no manual setup. The image goes in, the video comes out.

Behind the Scenes: How the Video Was Made

If you want to see exactly what the user-facing workflow looks like — every click, every field, every option — this short screen recording walks through the entire process of producing the explainer video above. It is the best way to see how little effort the workflow actually requires.

Watching that recording end-to-end is the fastest way to understand why this is now genuinely realistic for everyday exam prep — there is no learning curve, no scripting, no editing.

Step-by-Step: Do This With Your Own Question

Want to try this on a problem you are stuck on? The process takes under a minute of your time (Golpo handles the rest):

• Step 1 — Capture the question. Take a screenshot of a digital question, or use your phone camera to photograph one from a textbook or printed paper. Make sure the image is clear and the full question (including any diagrams and answer choices) is visible.
• Step 2 — Open Golpo. Go to video.golpoai.com and start a new video.
• Step 3 — Upload the image and prompt. Attach the screenshot and write a short prompt like "Solve this IIT JEE Advanced question step by step and explain each step on the whiteboard. End with the correct answer choice." The more specific your instruction, the better the resulting video matches how you want it explained.
• Step 4 — Pick the style. For exam questions, the whiteboard sketch style is usually the right call — it mirrors how a tutor would actually teach the problem on a board. You can also choose narration voice, language, and approximate video length.
• Step 5 — Generate and wait. Click generate. The video is typically ready in 10 to 15 minutes. You will get a notification when it is done.
• Step 6 — Watch, replay, share. The output is a standard MP4 you can stream, download, embed, or share with a study group.

Why This Is a Big Deal for Test Prep

Generating an explainer video for a single exam question used to be either expensive (a tutor) or unscalable (recording your own). AI changes both sides of that equation at once.

• For students: Every question in every past paper now has a worked video walkthrough waiting to be generated. You are no longer dependent on whether some YouTuber happened to cover the problem you are stuck on.
• For tutors and coaching centers: Instead of writing the same solution to the same problem dozens of times, you can hand a student a custom-generated video and use your time on the conceptual gaps that actually need a human.
• For ed-tech platforms: Entire solution libraries for JEE, SAT, AP, AIME, MCAT, GRE, GMAT, NEET, UPSC and similar exams can be generated programmatically. This was previously a multi-million-dollar production cost.
• For self-learners and homeschoolers: Any textbook problem becomes its own short video lesson, on demand, in whatever language you prefer.

What Kinds of Questions Work Well

The IIT JEE example above is on the harder end of the difficulty curve and Golpo handled it cleanly. In practice, almost any question that can be expressed as a screenshot is fair game:

• Math: Algebra, geometry, calculus, vectors, probability, combinatorics, linear algebra.
• Physics: Mechanics, electromagnetism, thermodynamics, optics, modern physics, problems with free-body diagrams.
• Chemistry: Stoichiometry, equilibrium, organic mechanisms, periodic trends.
• Biology: Genetics problems, biochemistry pathways, ecology calculations.
• Computer science: Data structures, algorithm analysis, complexity, code-tracing problems.
• Standardized tests: SAT Math and Reading, ACT, AP exams, GRE Quant, GMAT, MCAT, LSAT logic games, AIME, AMC, Olympiads.
• Competitive entrance exams: JEE Main, JEE Advanced, NEET, UPSC, GATE, CAT, CUET, and equivalent exams from any country.

If you can take a clear picture of it, Golpo can usually turn it into an explainer.

Tips for Better Output

A few small things you can do to get sharper, more accurate explainer videos:

• Use a clean screenshot. If the question is from a digital paper, screenshot it directly rather than photographing your screen. Glare and angle make OCR harder.
• Include the answer choices. If the question is multiple-choice, leave the options visible in the image. The AI will explicitly identify which option is correct at the end of the video.
• Be specific in your prompt. "Solve and explain step by step on the whiteboard, identify which of the options A, B, C, D are true, and briefly explain why the wrong ones are wrong" produces a noticeably better video than "Solve this."
• Pick a language. Golpo supports narration in many languages — if you study in Hindi, Tamil, Spanish, French, or any other language, the video can be generated in it directly. The whiteboard visuals are language-agnostic.
• For long problems, allow more length. Multi-part questions like the JEE example above need a longer video to walk through each part — give the generator room.
