how it works

From question to answer with one shortcut

No copying, no new tabs, no retyping the question into a chatbot.

  1. Download Hidio

    The app installs in under a minute on Windows or Mac. Sign in with your email; your first 5 answers are free.

  2. Press Alt+Shift+S

    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.

  3. Read the answer in your Hidio window

    The answer comes first, then the working step by step. Alt+Shift+H hides the window; Alt+Shift+↑/↓ scrolls long answers.

Built to stay out of sight

Hidio runs as its own app on your computer: nothing is added to the web page, and nothing is installed in your browser.

Every subject, shown step by step

Algebra and calculus, chemistry, physics, biology, economics, accounting, statistics, history, English and coding — including questions with charts, graphs and diagrams.

  • Calculus
  • Statistics
  • Chemistry

“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.”

Frequently asked questions

For anything else, contact support@hidio.app.

Can anyone see Hidio during screen sharing?

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.

Does Hidio change the web page or my browser?

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.

Which sites and apps does it work on?

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.

How accurate is it?

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.

Do I need to type or copy the question?

No. Press Alt+Shift+S (Option+Shift+S on a Mac) and Hidio reads the screen under your cursor.

Which computers does it run on?

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.

How do I cancel my plan?

Open your account on hidio.app and click Cancel plan. You keep access until the end of the period you paid for.
