TurboLearn AI (Turbo AI): from lecture recordings to flashcards and quizzes for 10 million learners

Updated on November 14, 2026

TurboLearn AI, rebranded as Turbo AI in late 2025, is an AI-powered note-taker that converts PDFs, slides, YouTube videos and lecture recordings into structured notes, flashcards, quizzes and podcasts. Cofounded by Sarthak Dhawan and Rudy Arora, two childhood friends who dropped out of Duke and Northwestern to build it full-time, the app claimed over 10 million learners as of July 2026. A free tier covers notes, flashcards and quizzes; the Turbolearn Unlimited subscription runs roughly $15–20/month or $70–120/year depending on the in-app price shown (iOS, Android, web). The platform is English-only.

How TurboLearn AI turns raw material into study sessions

Turbo AI starts from a single source and fans it out into several study formats. Drop a PDF syllabus, a DOCX file, a YouTube link or hit the mic button during a lecture. The AI produces editable notes inside a Google-Docs-style editor, then generates flashcards sorted into New / Learning / Mastered buckets, multiple-choice or fill-in-the-blank quizzes, and even a short podcast summarising the content.

The built-in chat answers questions drawn directly from your files, so there is no need to search through the original document. Equations, physics diagrams and code snippets are supported, though student feedback on Reddit and Google Play flags occasional inaccuracies with complex formulas. A quick sanity check of the generated notes before diving into practice goes a long way.

Learn Mode, shipped in 2026, creates a structured mini-course from just a few keywords.

• Structured notes with tables, emojis and diagrams
• Flashcards with progress tracking (New, Learning, Mastered)
• MCQ and fill-in-the-blank quizzes with AI explanations
• Audio podcasts generated from uploaded content
• Pre-made AP study guides library

From dorm project to 10 million sign-ups

Dhawan started coding the prototype as a freshman at Duke in 2023, and the public launch came in early 2024. By October 2025 the app had reached 5 million registered learners in roughly 18 months; it hit 10 million in July 2026, alongside, according to the company, 50 million notes generated and over one billion flashcards, quizzes and podcasts produced. The rebrand from TurboLearn AI to Turbo AI (turbo.ai domain) was purely cosmetic: accounts, stored data and pricing stayed the same.

Based in Los Angeles with a lean team, the company raised only $750,000 and reports being profitable, with a cumulative revenue of $13 million according to Business Insider (June 2026). Direct competitors cited in press coverage include Otter, Fireflies and YouLearn, while dedicated flashcard platforms like Quizlet serve a partly overlapping audience. Among AI-powered education tools, Turbo AI stands apart by bundling note-taking and active-recall exercises into a single workflow.
