Get instant AI-powered homework help for any subject

Why it's here: Completely free to use with no hidden paywalls or premium tiers

Socratic is a free AI-powered learning app developed by Google that helps students understand difficult concepts by providing step-by-step explanations, visual aids, and curated educational resources. Designed primarily for middle school, high school, and college students, Socratic allows users to take a photo of a question or type it in, and the app's AI quickly analyzes it to surface the most relevant explanations, videos, and definitions from across the web. What makes Socratic particularly useful is its multi-subject coverage, spanning mathematics, science, history, English literature, and more, so students can use it as a single go-to resource rather than hunting across multiple websites. The tool emphasizes genuine understanding over simply providing answers, often breaking down complex problems into digestible steps and linking to trusted sources like Khan Academy and Wikipedia. Whether you're stuck on a calculus problem late at night or trying to wrap your head around a history essay prompt, Socratic offers accessible, judgment-free academic support right from your smartphone.

Personalized AI tutoring and instant feedback for every student.

Why it's here: Saves teachers significant grading time by automating rubric-based feedback and syncing grades directly to popular LMS platforms

Class Companion is a freemium AI teaching assistant designed to bring one-on-one tutoring and rubric-based feedback to every K-12 student in the classroom. The platform empowers teachers to assign writing and other tasks, then lets an AI tutor guide students through the work with real-time, personalized feedback tied directly to teacher-defined rubrics. Rather than waiting days for a graded paper to come back, students receive immediate, actionable guidance that helps them revise and improve before submitting a final draft. Teachers benefit equally, as the tool automatically syncs rosters and grade data with popular learning management systems including Canvas, Schoology, and Google Classroom, dramatically reducing the administrative burden of grading. Class Companion is especially well suited for English Language Arts, social studies, and any subject that involves written responses, making it a practical solution for teachers managing large class sizes who want to provide the kind of individualized attention that is otherwise impossible to scale. By sitting between the teacher and the student, the AI acts as a tireless first-responder to student questions and drafts, allowing educators to spend more classroom time on discussion, intervention, and enrichment rather than grading stacks of assignments.
