I asked two different AI assistants the same question and got two answers. Compare them so I can decide what to trust and what to check. You are a neutral reviewer, not a third contestant.

My original question or task (exactly as I asked it): {{original question}}
Context both assistants were given: none
How I will use the answer, and the cost of being wrong: {{use and stakes}}

Answer A (from assistant A):
{{answer A}}

Answer B (from assistant B):
{{answer B}}

Please produce:
1. Agreement: the points both answers make. Note that agreement between two assistants is not proof, since they can share the same mistakes.
2. Disagreement: a table with the topic, what A says, what B says, and your assessment of which is more likely right and why, or "cannot tell" if you cannot decide. Quote the wording that differs.
3. Only in A and only in B: useful points that appear in just one answer, and whether the other answer should have included them.
4. Differences that are only style, length or format and do not affect substance.
5. Weak spots in each: unsupported claims, suspiciously precise numbers, invented references, hedging that hides a gap and anything that does not answer what I asked.
6. What to verify and how: the three differences most worth checking given my stakes, and the kind of source that would settle each.
7. A combined answer, only if both answers are good enough to merge. Mark each statement as agreed, from A only or from B only, and keep disputed statements out of it.

Rules: do not decide a factual dispute by guessing. If you cannot judge, say so. Do not use my wording or preferences to favor one assistant, and do not claim to have verified anything.

4 required fields are empty and will stay as a {{placeholder}} in the copied text.

How to use it

  1. Ask both assistants the exact same question with the same context. Different prompts make the comparison meaningless.
  2. Paste the answers in full, with the assistant names, so the review can refer to each by name.
  3. Run the comparison in a third conversation, or in one of the two assistants, but tell it to act as a neutral reviewer.
  4. Verify the top differences in primary sources. Two assistants agreeing is a reason to be somewhat more comfortable, not a reason to stop checking.

Example output

Illustrative only. Real answers depend on your input and the assistant you use.

Agreement: both recommend a staged rollout and both say to back up the database before migrating.

Disagreement
| Topic | Chat A | Chat B | Assessment |
|---|---|---|---|
| Downtime | "no downtime is needed" | "plan a 15 minute maintenance window" | Cannot tell. Depends on your database version, which neither asked about. |
| Index step | Create indexes before migrating | Create indexes after migrating | B is more common practice for large tables, but check your database documentation. |

Only in A: a rollback script. Only in B: monitoring queries for after the cutover. Each is useful and missing from the other.

Style differences: B is longer and uses headings; the substance is the same.

Weak spots: A states "this takes about 5 minutes" without knowing your data size. B cites a documentation page by name but gives no link; verify it exists.

Verify first: the downtime claim (high stakes), the index order, and the cited page.

Combined answer: not provided, because the downtime point is disputed and central.

Tips

When two assistants disagree, the useful result is a list of what to check, not a winner. That is why the prompt asks for verification steps rather than a verdict.

If both answers are wrong in the same way, the comparison will not show it. Use primary sources for anything that matters.

If you compare models often, keep the questions and both answers together so you can see over time where each one tends to be stronger.

To choose which two assistants to compare, the AI Model Directory lists models with their context windows and pricing. If you use HistChat, the same question and both answers can stay searchable in one place, since it indexes ChatGPT, Claude, Gemini and Grok conversations on your own device.
