Capture from Images

Photograph a textbook page, slide, whiteboard, or screenshot and Neurako will extract flashcard drafts using OCR and AI.

Point your camera at a textbook page, slide, whiteboard, or screenshot and Neurako uses OCR and AI to extract the content and generate flashcard drafts. Results are always shown for review before saving.

Key Takeaways

Works with printed text, typed notes, presentation slides, and clear whiteboards — not well-suited to heavy cursive or very small text - Camera capture is primarily a mobile feature; web supports image file upload instead - The AI decides which content becomes which cards — always review and edit the drafts before saving - Good lighting and a flat, unobstructed view significantly improve extraction quality

How image capture works

Open the Create tab on mobile and tap the camera icon, or choose "Upload image" in the web create flow.
Take a photo of your study material, or select an existing image from your library.
Neurako performs optical character recognition (OCR) to read the text, then the AI identifies key concepts and structures them into card front-and-back pairs.
A preview screen shows every generated draft. Edit, delete, or add cards as needed.
Save the reviewed cards to your deck.

The OCR and extraction steps happen on Neurako's servers. Results typically appear within a few seconds for a single page.

What works well

Image capture produces the best results with:

Printed textbook pages — clean typography, high contrast, and defined structure give the AI clear material to work from
Presentation slides — title-and-bullet layouts translate naturally to card fronts and backs
Typed or printed notes — structured notes with clear headings, numbered lists, or defined terms
Whiteboards with block lettering — large, clearly written text in high contrast

What works less well

Some inputs produce noisier results:

Heavy cursive or stylized handwriting — OCR accuracy drops significantly with non-standard letterforms
Very small text — font sizes that are hard to read in person are harder to extract digitally
Low-contrast images — pencil on white paper, light ink, or washed-out photos reduce OCR reliability
Cluttered or dense pages — pages with multiple columns, overlapping annotations, or dense footnotes may produce unexpected card groupings

Tips for better results

Lighting: Natural or bright even lighting works best. Avoid shadows across the page — they obscure characters and confuse OCR. If you're indoors, position the page near a window or under a ceiling light directly overhead.

Orientation: Hold the camera directly above the page rather than at an angle. Keystone distortion (trapezoidal skewing) reduces character recognition accuracy. Most phone cameras handle portrait and landscape equally well; use whichever fills the frame with your target content.

One page per capture: Avoid photographing two pages of an open book at once. The spine creates a shadow and the curved inner edges of the pages reduce text clarity. Capture each page separately.

Avoid shadows from your hand or phone: Hold the phone far enough above the page that your device doesn't cast a shadow over the content.

Reviewing and editing the results

Image capture is approximate — the AI makes decisions about which text segments belong together as a card, and those decisions aren't always right. After the extraction, expect to:

Delete cards that contain irrelevant text (headers, footers, page numbers, captions)
Fix fronts and backs where the AI split a concept incorrectly or reversed the question and answer
Add cards manually for content the AI skipped or combined awkwardly

The review step is always required — captured cards are drafts, not finished output.

Mobile

Use the camera icon in the Create tab to photograph study material directly. You can also select an existing image from your photo library if you've already taken a photo.

Web

On web, choose "Upload image" in the create flow and select a screenshot or saved image file from your computer. Direct camera access is not available on web.
