Its headline capability is a math solver that cross-checks each result with several AI models before presenting the solution, then walks through the steps so the reasoning is visible. You can type a problem, paste text, or upload a photo of equations, diagrams, and word problems, and the tool returns a solution in seconds with an explanation of why each step matters. The site says it covers math, calculus, chemistry, biology, business, and social science, from elementary level through college. The platform is broader than problem solving. It accepts lecture slides, textbook chapters, articles, audio recordings (MP3, WAV, M4A and similar, up to 60 minutes), and YouTube links, then turns that material into structured study notes, question-and-answer flashcards, short and detailed summaries, key-point lists, and multiple-choice or short-answer quizzes. That makes it useful for exam prep: a recording or a lecture link becomes a set of revision assets in a few steps. Feen runs in any web browser and works on phone, tablet, or computer, so there is nothing to install. It offers a free tier with a limited number of daily queries, and paid subscriptions are billed through Stripe with the option to change or cancel plans from account settings; the site notes a 7-day refund window. The FAQ is candid that it is a learning aid rather than a way to bypass coursework, and that users should still review each step. **Pricing & Plans:** Free plan with a daily query limit; paid subscriptions are available and billed via Stripe, with cancellations allowed anytime. - **Self-checking math solver:** Multiple AI models verify each answer before it is shown, then the solution is broken into clear steps with explanations. - **Notes and summaries from any source:** Turn lecture slides, textbook chapters, articles, or transcripts into structured notes, key points, and short or detailed summaries. - **Audio and YouTube transcription:** Upload recordings up to 60 minutes or paste a YouTube link to get a transcript you can convert into study material. - **Flashcards and quiz generation:** Convert notes or source material into question-answer flashcard sets and multiple-choice or short-answer quizzes. - **Multi-subject coverage:** Handles math, calculus, chemistry, biology, business, and social science from elementary through college level. **Strengths:** Solutions are step-by-step rather than answer-only, which supports actual learning; Cross-checks answers with several models for extra confidence; Turns one source into notes, flashcards, and quizzes in a single workflow; Runs entirely in the browser with no installation **Limitations:** Free tier limits the number of queries per day; Audio uploads are capped at 60 minutes, so longer lectures need splitting; AI output still needs review; the site itself warns against using it to skip the learning [Profile (Markdown)](https://openaitools.app/tool/feen-ai.md) ## Studyable Studyable bundles several study workflows into one free web app. Its AI chat tutors cover school subjects from algebra and chemistry to history and literature, and they accept photos of handwritten problems, diagrams, or textbook pages so students can ask about a question exactly as it appears on the page rather than retyping it. The Essay Grader is the other core piece: paste or upload a draft and Studyable returns structured feedback on thesis, organization, evidence, grammar, and style, so students can revise before submitting. Alongside that, Studyable generates flash cards and practice questions from notes or pasted text, giving it a role in both homework completion and exam prep. Because JAVASCRIPT-heavy interfaces load dynamically, light crawlers and some browser setups may see a near-empty page. In normal use, opening studyable.app in a current browser loads the chat, grader, and flash card tools directly, with a free tier that requires no payment details. **Pricing & Plans:** Advertised as a free study app — the core homework help, tutoring, essay grading, and flash card tools are accessible without payment. Verify current plan limits on studyable.app. - **Step-by-step homework help:** Ask a question in chat and the tutor explains each step of the solution instead of dropping a bare answer. - **Tutors that can see images:** Upload or photograph a problem, diagram, or page and ask about it, useful for handwritten math and science work. - **Essay Grader feedback:** Submit a draft essay and receive structured critique covering argument, structure, evidence, and language. - **Flash cards and practice questions:** Turn notes or reading material into study cards and self-test questions for revision sessions. - **Multi-subject coverage:** Works across maths, sciences, humanities, and languages rather than a single narrow subject. **Strengths:** Genuinely free entry point with no payment details needed for core tools; Tutors accept images, so problem sets do not have to be retyped; Combines homework help, essay grading, and flash cards in one place; Explanations are written in student-friendly plain language **Limitations:** AI-generated feedback can miss nuance or reflect a wrong premise — treat it as a second opinion; Heavy client-side rendering means some browsers and older devices may load slowly; No substitute for teacher guidance on graded work or subject-specific conventions [Profile (Markdown)](https://openaitools.app/tool/studyable-app.md) ## Frequently Asked Questions ### How do Feen AI and Studyable compare in monthly traffic?
