Studdy

Studdy operates a consumer AI tutoring application marketed as "Studdy Buddy," available on iOS and Android and through its website. Students enter a topic or upload assignments, textbooks, practice exams or photographs of problems; the product recognizes diagrams, word problems and handwritten work, then produces a step-by-step explanation and a personalized lesson taught on an interactive whiteboard with visual and audio elements. Learners can interrupt with follow-up questions at any step, and the system adapts to their pace and stated goals.

Subject coverage spans mathematics (algebra, geometry, trigonometry, precalculus, calculus I-III, multivariable calculus, differential equations, linear algebra, probability and statistics), sciences (physics, chemistry, biology), economics, and literature and humanities subjects including history, English, reading, writing and languages, at levels from K-12 through college. Additional features include custom video tutorials, graphing of problems, generation of extra practice problems, and unlimited chat-based tutoring.

The company positions Studdy as purpose-built for students rather than a general-purpose chatbot, emphasizing multilingual explanation at the user's grade level and comprehension checks intended to prevent students from simply copying homework answers.

Founding story

Co-founders Michael Lam and Alex Lanzoni built Studdy based on their own experiences as students who struggled with lecture-based instruction and lacked after-hours help with homework. Lanzoni left college at 19 and is described as a self-taught software engineer with 13 years of experience; Lam spent four years working in ed-tech and AI at Photomath and then at Speak, where he helped build an AI language tutor on GPT-3 and GPT-4. The two had previously worked together at Starcity before starting Studdy.

Business model

Studdy sells a freemium consumer subscription. The free tier allows a limited number of problem scans per day (five on iOS), coverage of every subject and grade, and unlimited chat-based tutoring. The paid tier, Studdy Plus, adds unlimited scans and chat, video tutorials, 1:1 lessons with the AI tutor, generated practice problems and increased accuracy. In-app purchases are also offered on the Android version.

Recurring subscription revenue via in-app purchase; Studdy Plus pricing starts at US $6.99 per week, charged through the Apple ID account and renewing automatically unless cancelled.

Traction

The iOS listing cites more than 500,000 students using Studdy Buddy and a 4.8 average rating across roughly 13,000 ratings; the Android app reports over 50,000 downloads. Third-party research cites over 250,000 downloads and millions of problems solved. The company's site names universities, including Harvard, MIT, Stanford, Princeton, Oxford, Cambridge and the University of Toronto, as institutions its student users attend.

Latest developments

The Android app listing was updated on 2026-01-14. The current website positions the product around unlimited 1:1 lessons across all subjects delivered on an interactive whiteboard, expanding beyond the original math-tutor framing.
