# QuickSnap (Mobile)

**Instant Quiz Solving**

Snap photos of any quiz or problem, and the app's AI will instantly process and provide answers.

**Text and Math Recognition**

The app excels at recognizing both printed and handwritten text, including complex math symbols and geometry figures. QuickSnap runs on **GPT-5 vision**, so it reads handwriting, equations, charts, and diagrams natively — no separate OCR step.

## Snap → Crop → Solve

Every QuickSnap goes through a three-step flow, designed to maximize accuracy on the part of the image that actually matters:

1. **Snap** — capture the page, problem, or document using your camera or photo gallery.
2. **Auto-crop** — the app intelligently detects the question region and **suggests a crop** for you. The detected area is highlighted with a green border on the preview screen.
3. **Solve** — tap **Validate** to send the cropped image to the AI. Within seconds you get the answer plus a step-by-step explanation.

## Smart Crop

The **Smart Crop** feature analyzes the photo as soon as you take it and proposes the tightest bounding box around the actual question — cutting out distractions like page margins, headers, your finger holding the book, and unrelated content on the same page.

You can:

* **Accept the suggestion** — just tap **Validate**.
* **Adjust the crop** — tap the crop icon (top-right of the preview) to redraw the region manually if Smart Crop missed something.
* **Skip cropping** — tap **Validate** without adjusting to send the full image.

Smart Crop dramatically improves accuracy on photos taken from textbooks or printed worksheets, where you often have multiple questions on the same page. By isolating the target question, the AI doesn't get distracted by surrounding content.
{% endhint %}

## Tips for best results

* **Good lighting** matters — avoid heavy shadows over the question.
* **Hold the camera parallel** to the page when possible — Smart Crop handles minor skew but extreme angles still hurt OCR.
* For **multi-step math problems**, snap the *whole problem* including any provided data tables or figures — the AI uses the full context.
* If a single image contains both the question AND the multiple-choice options, capture all of them — QuickSnap will pick the best answer from the choices.

## Capture preferences

Everything that controls the capture flow lives under **Settings → Camera & Capture**. As of v2.1.1 you can tune:

* **Default camera** — **Rear** (default) or Front. Rear is best for textbooks and worksheets; Front is handy for stitching quick notes to yourself.
* **Capture quality** — sharper photos produce better OCR but larger files. Default: **Standard**. Bump it up if you routinely capture small text.
* **Upload quality** — the pixel cap on images sent to the AI. Default: **Standard · 1200px**. Higher values improve OCR accuracy on dense text but consume more data. Lower values are gentler on mobile data plans.
* **Auto-open crop after capture** *(toggle, off by default)* — when on, the app skips the preview step and jumps straight into the crop editor. Useful once you're comfortable with the workflow and want to save a tap per capture.

If any of these settings drift and you're not sure what changed, **Settings → Data & Storage → Reset settings to defaults** puts everything back to factory values.
