Use CamScanner to extract formulas from images. Powered by OCR recognition engine that detects formula regions in images, crops them, and stitches into a single clean PNG image. Use when the user wants to extract mathematical formulas, equations, or expressions from images (photos, screenshots, scanned documents). Triggers on "extract formula", "get formulas from image", "crop formulas", "formula extraction", or when the user has an image containing math formulas and needs them extracted as a clean image.
Use CamScanner to detect whether an image was generated by an AI model (e.g. Stable Diffusion, Midjourney, DALL·E). Powered by an AIGC-detection engine that classifies an image as genuine, suspected AI-generated, or AI-generated, with a confidence score. Returns a JSON result containing `ai_check_result` (1/2/3), `confidence`, and `result_text`. Use when the user asks whether a photo is AI-generated, wants to verify an image's authenticity against AI generation, or asks "is this AI art / Stable Diffusion / Midjourney?". Triggers on "检测AI生成", "是不是AI画的", "AIGC检测", "AI图片识别", "detect AI-generated image", "is this AI art", "is this diffusion / midjourney", or when the user shares an image and asks whether it was produced by AI.
Use CamScanner to detect whether an image has been PS-edited, manipulated, or tampered with. Powered by a manipulation-detection engine that identifies photo-editing traces, splicing, retouching, and other signs of tampering. Returns a JSON result with `is_tampered` (boolean) and `result_text` (human-readable). Use when the user asks whether a photo is genuine, wants to verify an image's authenticity, or asks "is this PS-ed / photoshopped / edited". Triggers on "检测图片是否PS", "是否被篡改", "图片验真", "PS检测", "detect image tampering", "is this photoshopped", "check if image was edited", or when the user shares an image and asks whether it has been modified.
Use CamScanner to erase handwriting from images while preserving the printed content and original layout. Powered by a high-precision image enhancement engine that intelligently detects and removes handwritten strokes, annotations, and signatures, leaving the underlying document clean and legible. Use when the user wants to remove handwriting from a photo or scan, clean up annotated documents, or restore a blank form filled by hand. Triggers on "erase handwriting", "remove handwriting from image", "clean handwritten notes", "remove annotations from scan", or when the user has an image with handwritten content that needs to be removed.
Use CamScanner to enhance image clarity and quality. Applies auto-crop then HD super filter to produce a cleaner, sharper image. Optionally removes moire patterns when explicitly requested. Use when the user wants to make an image clearer, sharper, higher quality, or HD. Triggers on "HD image", "enhance image clarity", "make image clearer", "sharpen image", "high definition", "improve image quality", "super filter", or when the user wants to improve the visual quality of a photo or scanned document. Only use demoire mode when the user explicitly mentions removing moire patterns.
Use CamScanner to remove watermarks from images while preserving the underlying content and original layout. Powered by a high-precision image enhancement engine that intelligently detects and erases overlaid watermarks, stamps, and translucent logos, leaving the underlying document clean and legible. Use when the user wants to remove watermarks from a photo or scan, clean up stamped documents, or recover a clean copy of a watermarked image. Triggers on "remove watermark", "erase watermark from image", "delete watermark", "clean watermarked scan", "unwatermark", or when the user has an image with a watermark that needs to be removed.
Use CamScanner to remove watermarks from PDF documents while preserving the underlying text, images, and original layout. Powered by a high-precision document enhancement engine that intelligently detects and erases overlaid watermarks, stamps, and translucent logos across every page, leaving the document clean and legible. Use when the user wants to remove watermarks from a PDF, clean up stamped PDFs, or recover a clean copy of a watermarked PDF. Triggers on "remove watermark from PDF", "erase PDF watermark", "delete watermark from pdf", "unwatermark pdf", "clean watermarked PDF", or when the user has a PDF with a watermark that needs to be removed.
Use CamScanner to translate text in images to another language while preserving the original layout. Detects text in the image, translates it to the target language, and renders the translated text back onto the image. Use when the user wants to translate text in an image, photo, screenshot, or scanned document to another language. Triggers on "translate image", "translate text in image", "image translation", "translate this to English/Japanese/Korean/etc.", or when the user has an image with foreign text and wants it translated.
