Upload homework questions, lecture recordings, PDFs, or videos to StudyX and get step-by-step answers, study notes, flashcards, and practice quizzes in one education-focused dashboard. The homework helper routes problems through GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro, and other models, then pulls related solutions from a 75-million-question community bank. Writing tools cover paraphrasing, grammar checks, AI detection, humanizing, and plagiarism scanning.

Where most homework apps solve one problem type, StudyX stacks the full study loop in a single dashboard. Its homework helper draws on a 75-million-question community bank and 85 million verified answers, then layers web search, academic paper lookup across 200 million sources, and related video lessons on top of the AI response. Paid tiers add monthly credit pools (3,000 to unlimited) plus 30 daily refresh credits, while the free tier grants 20 credits per day with core homework and writing features.

High school and college students use StudyX for nightly assignments and exam cramming. Working professionals refreshing math or certification topics (NCLEX, CPA, PMP prep pages are listed on the site) also show up in StudyX's own audience copy. Apps run on web, iOS, and Android with optional sign-up for the free homework helper.
