Prepare your LLM API Key 23 | 4. During the first launch, grant overlay, screenshot, and notification permissions as requested. 24 | 25 | ### Quick Start 26 | 1. Launch the app, tap “Enter answering mode,” and confirm that all permissions are granted. 27 | > Screenshot placeholder: Permission dialogs 28 | 2. Open the screen with your question and tap the floating button to capture it. 29 | > Screenshot placeholder: Floating button guide 30 | 3. Review the recognized text in the confirmation view; adjust it if anything looks off. 31 | 4. Tap “Confirm & solve” to receive the AI-generated answer, which is also copied to your clipboard. 32 | 5. To exit, return to the main screen and tap “Stop service.” 33 | 34 | ### Supported Question Types 35 | - Multiple choice: Extracts question and options, highlights a recommended answer with reasoning 36 | - Fill in the blank: Produces concise entries for each blank slot 37 | - Short/long answer: Supplies structured explanations or outline-style responses 38 | 39 | ### Tips & Tricks 40 | - Keep screenshots sharp and centered, and avoid busy backgrounds to improve OCR accuracy. 41 | - Pause AI requests by toggling the setting in-app or briefly disconnecting from the network. 42 | - Capture again at any time via the floating button to continue practicing new questions. 43 | 44 | ### FAQ 45 | - **Missing permissions?** Open system settings, search for “overlay” or “screen capture,” and enable the required entries manually. 46 | - **Incorrect recognition?** Edit the text on the confirmation screen or retake the screenshot. 47 | - **No AI response?** Verify connectivity, confirm your API Key, and make sure your DeepSeek balance covers the request. 48 | 49 | ### Privacy & Disclaimer 50 | - Recognized text is sent to your chosen AI provider; avoid sensitive or restricted content. 51 | - DeepSeek usage may incur costs—monitor your API consumption responsibly. 52 | - AIAnswerer is for learning and research purposes only. Respect exam rules and local regulations; you are accountable for any misuse. 53 | 54 | ### Update instructions 55 | #### v0.3 56 | Added the pre-COR cropping function to improve the ability to
