About

ThinkAssist is an iPhone and iPad AI homework helper for students who want any homework question, in any subject, explained and solved step by step from a single photo.

Take a photo of a question, a worksheet or a textbook page, or type the question in. Handwriting works too. Students don't pick a subject first. ThinkAssist recognizes the subject and topic by itself, whether it's algebra, chemistry, history or an English essay, from elementary school up to college.

Math solutions are broken into short steps, with equations, fractions and formulas shown the way they look in a textbook, so even long solutions are easy to follow on a phone.

Every answer is explained step by step, so students can see how it was reached. Think Deep mode spends longer on hard problems, students can ask about any step in a follow-up chat, and answers stay saved for exam revision.

Free to download: $29.99/year after a 7-day free trial, or $6.99/week after a 3-day free trial. No ads.

It's an alternative to Photomath, which only does math, to Socratic, which Google discontinued, and to Gauth, Brainly and Chegg. ThinkAssist has been on the App Store since 2023 and is rated 4.6 from more than 200 ratings, 110 of them in the US.

Competitors: Photomath, Socratic, Gauth, Brainly, Chegg

From the founder

Who it's for

“Students from elementary school up to college, and their parents. They're stuck on a homework question in any subject, from algebra and chemistry to history or an English essay, and want to see how it's solved, step by step, not just the final answer.”

About me

“I'm Zoli Dross, an indie iOS developer: 9 apps under Dross Creative, bootstrapped. I built ThinkAssist in 2023 because the homework apps I saw either only did math or just handed over an answer. I wanted one app that takes a photo of any question, works out the subject by itself and explains every step, with math shown the way it looks in a textbook.”

— Zoli Dross, founder of ThinkAssist

Who it is for

Students from 3rd grade through college seniors
High school students getting help with math, science, and history assignments

FAQ

How accurate is the AI solution?

ThinkAssist uses state-of-the-art Large Language Models specifically fine-tuned for academic accuracy. While no AI is perfect, we provide step-by-step reasoning so you can verify the logic yourself.

Is ThinkAssist good for solving math problems?

Yes! Our AI is designed to handle complex math problems, from basic arithmetic to advanced calculus. It provides detailed step-by-step solutions, showing all the work so you can understand the process.

Can it read my messy handwriting?

Yes! Our advanced OCR (Optical Character Recognition) and AI analysis is designed to interpret handwritten notes, whiteboard scribbles, and printed textbook problems with high precision.

Why should I choose ThinkAssist over other homework helper apps?

ThinkAssist provides detailed, easy-to-digest explanations and step-by-step solutions to help you understand the material, rather than just giving you the final answer. On top of that, we've put an enormous amount of effort into making the app fast and user-friendly with as little manual input from you as possible. Nothing proves it better than the 4.6 App Store rating and the fact that most of our users come back to the app on a daily basis.

Does the app support text inputs as well? Can I chat with it like a tutor?

Yes. You can type your questions in the app or snap a picture. It's your call.

Is ThinkAssist considered cheating?

It depends on how you use it. We position ourselves as a study companion. Our goal is to explain the 'how' and 'why' behind a problem, helping you understand the material better for your exams, rather than just giving a final answer.

Does it work for college-level courses?

Absolutely. ThinkAssist supports everything from elementary school basics to advanced University-level Calculus, Organic Chemistry or Physics.

How much does it cost?

There are two plans, each starting with a free trial with unlimited access to all features. The yearly plan is $29.99 a year (about $0.58 a week) after a 7-day free trial. The weekly plan is $6.99 a week after a 3-day free trial.
