Feen AI

Feen AI is a browser-based study tool that solves math and science problems step by step, with three models verifying each answer. It also turns lectures, videos, audio and textbooks into notes, flashcards, quizzes and summaries.

Feen AI is a web-based study assistant that combines a step-by-step problem solver with tools for turning course material into revision aids. Students can type a question, paste text or upload a photo, including equations, diagrams and word problems, and receive a worked solution rather than a bare result. The product's central claim is that three AI models verify each answer, which positions it as a solver that checks its own work. Beyond problem solving, the homepage lists a set of study workflows. Lecture slides, textbook chapters and articles can be converted into structured notes. Audio recordings in common formats such as MP3, WAV and M4A can be transcribed, with uploads of up to 60 minutes. A YouTube link can be pasted to pull a transcript. Any of these outputs can then be reshaped into notes, summaries, flashcards or quizzes, the latter covering multiple-choice and short-answer questions. Output types are chosen from a row of options under the upload box: step-by-step solving, study notes, flashcards, quizzes, and detailed or short summaries with key points. Subject coverage is stated as math, calculus, chemistry, biology, business and social science, from elementary level through university. Feen runs in any browser on phones, tablets and computers, and a chat history sits in a sidebar once a user signs in. The site says problem data is processed to produce a result and then neither stored nor shared. In practice it suits high school and university students who want worked explanations for homework, plus anyone who needs fast notes and practice questions from lectures or videos. Compared with single-purpose math solvers, it covers more of the study cycle in one place. Compared with general chatbots, it offers purpose-built input formats and output types, though it is narrower in scope. The site stresses that it is meant for learning and checking work, and asks users to follow their school's academic honesty rules. A limited free daily allowance exists, with paid plans billed by card through Stripe.
