how it works
No copying, no new tabs, no retyping the question into a chatbot.
The app installs in under a minute on Windows or Mac. Sign in with your email; your first 5 answers are free.
With the question on screen, press the shortcut (Option+Shift+S on a Mac). Hidio reads the question, the options, graphs and diagrams, in any website or app.
The answer comes first, then the working step by step. Alt+Shift+H hides the window; Alt+Shift+↑/↓ scrolls long answers.
one small window
Hidio runs as its own app on your computer: nothing is added to the web page, and nothing is installed in your browser.
Algebra and calculus, chemistry, physics, biology, economics, accounting, statistics, history, English and coding — including questions with charts, graphs and diagrams.
“Stats homework went from two hours to twenty minutes. The steps actually make sense so I can redo them myself.”
Maya R. · Sophomore, Psychology
“I keep Hidio open next to Connect. One shortcut and the answer is there. It reads the graphs too, which nothing else did.”
Jordan T. · Freshman, Nursing
“Way faster than typing questions into a chatbot. Weekly plan during finals is a no-brainer.”
Aisha K. · Junior, Business

On Windows, no. Windows keeps the Hidio window out of every screenshot, recording and screen share, including sharing your entire screen in Zoom, Teams, Meet or Discord. Only your own monitor shows it. On a Mac, screenshots and window sharing leave Hidio out; full-screen sharing on macOS 15 and later can include it, so share a single window or tab there.
No. Hidio is a desktop app for Windows and Mac. It adds nothing to the web page, never opens a tab and installs nothing in your browser.
Anything on your screen: Canvas, Blackboard, Brightspace, Moodle, Google Forms, McGraw Hill Connect, Pearson MyLab, Cengage, WebAssign, Quizlet, Khan Academy, PDFs, Word documents, slides and desktop apps.
Hidio reads the full question, every option and any chart or diagram on screen, then works the problem through before answering. Every answer shows its steps, so you can check the reasoning.
No. Press Alt+Shift+S (Option+Shift+S on a Mac) and Hidio reads the screen under your cursor.
Windows 10 and 11, and macOS 11 or later on Apple Silicon and Intel Macs. On a phone, tablet or Chromebook, paste a screenshot at hidio.app/app.
