Free Online Question Scanner
Not everyone wants to download another app to their phone. Our online scanner works entirely in your web browser. It uses your device's camera through the browser's built-in camera API, so there is nothing to install and nothing that takes up storage on your phone.
The online version uses the same AI engine as our app. You get identical accuracy, the same step-by-step explanations, and the same multi-subject coverage. The only difference is that it runs in your browser instead of a dedicated app.
How to Use the Online Scanner
- Click the "Allow Camera" button when your browser asks for permission
- Point your phone or laptop camera at the question you want to solve
- Tap the capture button to take a photo
- Wait 3-5 seconds while the AI processes your question
- Read the complete answer with step-by-step explanation
Alternatively, you can upload a photo you already have. Click the upload button, select an image from your device, and the scanner processes it the same way as a live camera capture.
Why Students Prefer the Online Version
No Storage Space Required
Many students run low on phone storage. Between photos, music, social media apps, and school files, there is often no room for another app. The online scanner uses zero storage space on your device because it runs entirely in the cloud.
Works on Any Device
The online scanner works on iPhones, Android phones, iPads, laptops, and desktop computers. Any device with a camera and a web browser can use it. This makes it perfect for students who need to scan from their school Chromebook or a shared computer.
No Account Required
You do not need to create an account, verify an email address, or provide any personal information. Just open the page and start scanning. Privacy-conscious students appreciate that we do not track or store their questions.
Always Up to Date
Because the scanner runs in the cloud, you always get the latest version of the AI model without waiting for app updates. Every improvement we make is instantly available to all online users.
Online Scanner Limitations
The free online version includes 5 scans per day (compared to 10 in the app). It requires an internet connection at all times. For unlimited scans and offline capability, consider downloading the full app from the App Store or Google Play.
Browser Compatibility
The online scanner works in all modern web browsers including Chrome, Safari, Firefox, Edge, and Opera. It uses standard web camera APIs that are supported by every major browser on both desktop and mobile platforms. On iOS devices, the scanner works in Safari and Chrome. On Android, it works in Chrome, Firefox, Samsung Internet, and other Chromium-based browsers. For laptop and desktop users, any browser released after 2020 provides full compatibility.
The web-based scanner does not require any browser extensions, plugins, or special permissions beyond camera access. When you first visit the page, your browser will ask for permission to use the camera. Once you grant this permission, the scanner is immediately available. You can revoke camera access at any time through your browser settings, and the scanner will switch to upload-only mode where you can submit photos from your device storage instead of using the live camera feed.
Online Scanner vs. Downloadable App
The online scanner and the downloadable app use the same AI engine and produce identical results. The choice between them comes down to personal preference and usage patterns. The online scanner is better for occasional users who do not want to install another app, students using shared or school-owned devices where app installation may be restricted, and users who want to scan from a laptop or desktop computer with a built-in webcam. The downloadable app is better for daily users who want the fastest possible experience, students who need offline capability for studying without internet access, and users who prefer the polished interface and notification features of a native app.
Power users often keep both options available. They use the app on their personal phone for daily homework and use the online scanner on their school Chromebook or library computer when their phone is not available. Since both options use the same account, your scan history and preferences sync across all devices automatically if you choose to create an account.
Online Scanner FAQ
Do I need to create an account to use the online scanner?
No. The online scanner works without any account creation. Simply visit the page, allow camera access, and start scanning. Creating an optional account gives you benefits like scan history, syncing between devices, and the ability to save frequently referenced answers, but it is never required for basic functionality.
Is the online version as accurate as the app?
Yes. Both versions send your scanned image to the same AI processing servers and return identical results. The only factor that affects accuracy is the quality of the image you submit. Phones typically have better cameras than laptops, so phone camera scans may produce slightly higher accuracy than laptop webcam scans, but this is a hardware difference rather than a software one. Uploading a high-quality photo from any device produces the best results regardless of whether you use the app or the online version.
Can I use the online scanner on a school Chromebook?
Yes, the online scanner works perfectly on Chromebooks through the Chrome browser. Since Chromebooks cannot install mobile apps, the web-based scanner is the ideal solution for students who primarily use school-issued Chromebooks for their homework. The scanner runs entirely in the browser and does not require any administrator-level permissions or software installation that school IT policies might restrict.
Using a Browser During an Exam?
Whether you use an app or a browser, scanning during an exam means using a device. Proctors detect devices, not specific apps. The medium does not matter -- if you are caught with a phone, you fail.
