StudyX
FreemiumAI homework helper with step-by-step solutions, smart notes, and flashcards used by 16M+ students
What is StudyX?
StudyX is a popular AI homework helper trusted by over 16 million students worldwide. The platform lets students upload homework, lecture materials, PDFs, or videos to get instant step-by-step solutions, smart AI-generated notes, flashcards, quizzes, and writing help. Unlike study tools that focus on one format, StudyX handles nearly everything students encounter — handwritten problems via photo, multiple-choice PDFs, lecture recordings, and long-form textbook chapters. The free tier is reasonably generous with 5 daily questions, AI notes, and math solutions, making it genuinely useful for casual users. Paid plans are Plus at $12.99/month ($59.88/year) for expanded question limits and additional features, and Ultra+ at $19.99/month ($95.88/year) for the most capable AI and highest limits. StudyX is available on web, iOS, Android, and as a Chrome extension, so students can get help wherever they study. For students who only need occasional homework help, the free plan is sufficient. For heavy users processing multiple assignments per day, Plus or Ultra+ are necessary. Compared to Knowt (free) or Khanmigo ($4/month), StudyX is more expensive but handles a broader range of input formats including videos.

FAQ
Is StudyX really free?
Yes, StudyX has a genuinely free tier that includes 5 daily questions, AI-generated notes, step-by-step math solutions, and basic flashcards. For occasional homework help, the free plan works well. Active students who need more than 5 questions per day need to upgrade to Plus ($12.99/mo) or Ultra+ ($19.99/mo).
How many students use StudyX?
StudyX reports over 16 million students using the platform. This scale makes it one of the largest AI homework helpers globally. The large user base means the platform is well-tested and reliable, with consistent uptime and regular feature updates. Community discussion on Reddit and TikTok shows broad adoption among high school and college students.
What can StudyX help with?
StudyX handles a wide range of student tasks: math problem solving with step-by-step solutions, essay help and writing assistance, reading comprehension from PDFs, video lecture summarization, flashcard generation, quiz creation, and general homework questions across subjects. Upload a photo, PDF, or paste a question, and StudyX generates help.
StudyX vs Knowt — which is better?
Knowt is free for all core features and focused on flashcards, study modes, and notes. StudyX has a more generous homework Q&A free tier but caps it at 5 daily questions before requiring payment. For pure flashcard study, Knowt is better value. For homework Q&A across formats (photos, videos, PDFs), StudyX is more capable.
Is StudyX cheating?
Like any AI homework helper, StudyX raises academic integrity concerns depending on how students use it. Using it to understand a concept, check your work, or get unstuck on a problem is generally fine. Submitting StudyX-generated solutions as your own work typically violates school honor codes. Students should review their institution's AI policy before relying on StudyX for graded assignments.
Does StudyX work on mobile?
Yes — StudyX has iOS and Android apps plus a web interface and Chrome extension. Mobile apps are heavily used for photo-based homework help (snap a picture of a problem, get a solution). This is one of the most common StudyX workflows and makes it competitive with dedicated mobile study tools.
How does StudyX compare to ChatGPT?
ChatGPT is more flexible and cheaper at $20/month (Plus) but requires students to write prompts for every task. StudyX has purpose-built student workflows — upload a PDF, get notes; snap a photo, get a solution — that save time versus writing ChatGPT prompts. For general AI help, ChatGPT wins. For homework-specific flows, StudyX is often more efficient.
