Analysis

This Reddit post highlights a significant limitation of ChatGPT: its unreliability in document analysis. The author claims ChatGPT tends to "hallucinate" information after only superficially reading the file. They suggest that Claude (specifically Opus 4.5) and NotebookLM offer superior accuracy and performance in this area. The post also differentiates ChatGPT's strengths, pointing to its user memory capabilities as particularly useful for non-coding users. This suggests that while ChatGPT may be versatile, it's not the best tool for tasks requiring precise information extraction from documents. The comparison to other AI models provides valuable context for users seeking reliable document analysis solutions.

It reads your file just a little, then hallucinates a lot.
