PDF summaries
Test whether the AI can cite sections, find contradictions and keep page-level details straight.
Files
Best AI for files, PDFs and documents.
File support is not a yes-or-no feature. Real document work depends on size, extraction, OCR, layout, tables, citations and whether the model keeps the full context straight.

Guide
What to test before choosing.
These notes avoid fragile plan details and focus on durable buying criteria: workflow fit, output quality, verification effort and risk.
Scanned files
OCR quality matters. If the text extraction is weak, the model will reason over bad input.
Spreadsheets
Check whether the tool can read tables, explain formulas and summarize rows without losing columns.
Long reports
Context handling matters, but bigger context is not automatically better reasoning.
MultipleChat angle
MultipleChat is worth testing for heavier document workflows because it supports document-focused tools and larger files.
Human review
Legal, finance, medical, HR and customer documents need human review and approved data handling.
Practical test
Run the same task through several models.
Use the same prompt, same file and same scoring rule. Compare the answer you would actually send, publish, present or commit.
| What to score | Good answer | Warning sign |
|---|---|---|
| Clarity | Easy to understand and structured for the audience. | Sounds smart but hides the actual answer. |
| Accuracy | Separates facts, assumptions and uncertain claims. | Confident claims without support. |
| Usability | Needs little editing before real use. | Requires a full rewrite or misses the task. |
| Risk | Flags privacy, legal, medical, financial or source issues. | Encourages blind trust in the output. |
