Source discovery
Perplexity is the obvious first test for web-backed answers, citations and research starting points.
Research
Best AI for research and source checking.
Research work needs more than fluent text. The model should help you find sources, separate facts from assumptions and show what still needs verification.

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.
Synthesis
Claude and ChatGPT can be useful when you provide documents and need a careful summary or argument map.
Google context
Gemini can be useful when the workflow is already tied to Google search, Workspace or long-context material.
Cross-checking
MultipleChat is useful when you want several models to disagree, critique and expose weak claims.
Do not skip
Open sources yourself. A cited sentence can still misread the document or overstate the conclusion.
Best test
Ask each model for sources, uncertainties, missing evidence and the strongest counterargument.
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. |
