Upload your handwritten answer sheet (PDF, JPEG, PNG, or HEIC) 2. Select your subject (GS1-GS4, Essay, or Optional) 3. AI evaluates using Vision Transformers — reads the image directly including diagrams, maps, and flowcharts 4. Receive detailed feedback: structure score, content depth, keyword coverage, missing dimensions, and model answer comparison 5. Iterate and resubmit to track improvement **Why Vision Transformers beat OCR+LLM**: Traditional OCR strips away layout, margins, diagrams, and visual elements before sending plain text to an LLM. This means diagrams, maps, mind maps, and flowcharts in your answer — all of which UPSC examiners value — are completely ignored. Acme AI's Vision Transformer model reads the raw image directly, evaluating visual structure and diagrams as a human examiner would. **FAQ**: - Q: Is there a free AI for UPSC answer evaluation?
