Direct Answer
ChatGPT cannot perform verbatim OCR. While ChatGPT (via GPT-4o) can analyze, translate, and describe images, it often summarizes, skips long paragraphs, or hallucinates words when tasked with exact document transcription. For accurate OCR, use FastOCR.
ChatGPT OCR vs Dedicated OCR Tools
Large Language Models (LLMs) like ChatGPT are designed for language completion, not transcription. This creates several key limitations when using them for document extraction:
1. **Hallucination Risk:** ChatGPT may guess illegible letters or reword phrases, rendering it unreliable for legal, medical, or financial documents. 2. **Truncated Output:** Uploading multiple pages to ChatGPT often triggers prompt length restrictions, resulting in incomplete transcripts. 3. **Format Layout Scrambling:** ChatGPT drops margin layouts, columns, and tabular lines. 4. **No Searchable PDF Export:** ChatGPT cannot generate a dual-layer PDF file with invisible searchable text. FastOCR creates searchable PDFs natively.

Does FastOCR use AI?
