OCR stays in this browser. Only the extracted text may be sent to a public translate API if your browser has no built-in translator.
Many university courses teach in English while you take notes in your own language. Paste a screenshot of a slide, whiteboard, Moodle page or Zoom share — OCR runs in your browser with Tesseract, so the image is not sent to SmartBio servers.
Best for short captures you cannot copy (locked slides, photos of the board, a single PDF page). For whole books or long PDFs, use a dedicated document translator; this tool is built for one-shot classroom use.
After OCR, text is translated with your browser’s built-in translator when available, otherwise a public text-only API. Clear, high-contrast slides work better than blurry phone photos.
Yes. Screenshot the slide (or photograph the board), paste it here, then copy the translation into your notes. Works with PowerPoint, PDF viewers, Moodle and many campus tools that block selection.
No. OCR runs entirely in your browser. SmartBio never receives the image. Only the extracted text may leave the device if translation uses a public API (when the browser has no on-device translator).
No — use it for one slide or a short capture. Long documents are slower and less accurate here; DeepL or similar tools are better for whole files.
Lens is strong on phone camera. This page is handy on a laptop: paste a desktop screenshot, translate to your language, copy into notes — no extra app and no signup.
