ThinkAssist

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.
