How to Make Claude and ChatGPT Review Each Other’s Work

Most people use one AI at a time. They ask Claude for a draft, like it well enough, and ship it. Or they ask ChatGPT, get something different, and wonder which version is better. The useful move is simpler: make them review each other on purpose, in one place, with clear roles.

You do not need API keys or a custom app for this. You need a shared brief, two prompts, and a rule about who goes next. Here is a workflow you can run today with the chat apps you already use.

Why peer review beats a second draft from the same model

One model talking to itself tends to polish its own habits. Ask the same chat to “improve this” and it often gets longer, smoother, and more confident without fixing the real problem. A second model has different defaults. Claude often pushes for structure and clarity. ChatGPT often pushes for coverage and alternatives. When each one has to respond to the other’s work, weak assumptions show up faster.

The point is not to crown a winner. The point is to force a critique pass before you decide.

Set roles before you paste anything

Write a short brief you will give to both. Keep it boring and specific:

• Goal (one sentence)
• Audience
• Constraints (length, tone, must-include, must-avoid)
• What “done” looks like

Then assign roles out loud in the prompts:

• Claude = Builder. Draft first. Prefer clear structure. Call out what is still fuzzy.
• ChatGPT = Reviewer. Do not rewrite from scratch unless asked. List what is weak, missing, or overconfident. Suggest fixes in bullets.

You can swap the roles on the next round. What matters is that only one AI is drafting while the other is criticizing.

Round 1: draft

Paste the brief into Claude with: “You are the Builder. Produce version 1 only. Stay inside the constraints. End with three open questions for the Reviewer.”

Save that reply somewhere both of you can see it later: a shared doc, a Notion page, or an AI Roundtable project notebook. The shared place is the whole trick. If the draft lives only inside Claude’s chat, ChatGPT never truly reviews the same artifact.

Round 2: critique

Paste the same brief and Claude’s draft into ChatGPT with: “You are the Reviewer. Do not produce a full rewrite. Return: (1) what works, (2) what is weak or missing, (3) factual or logic risks, (4) a punch list of edits for the Builder. Be specific. Quote lines when you can.”

If ChatGPT cannot post into your shared room by itself, that is fine. Copy its critique into the same place under the name ChatGPT. The review still lands next to the draft.

Round 3: revise against the punch list

Back to Claude: “Here is the Reviewer’s punch list. Produce version 2. Address each item or explain why you rejected it. Keep the same constraints.”

Optional Round 4: send version 2 back to ChatGPT for a short pass/fail on the punch list only. Stop there. Endless ping-pong wastes time. Two or three turns is enough for most writing and planning tasks.

Rules that keep the review honest

• One artifact. Both AIs must see the same draft text, not a paraphrase you typed from memory.
• Name who goes next. End every message with “Next: ChatGPT” or “Next: Adis.” Ambiguity is how the relay dies.
• Ban empty praise. Tell the Reviewer that “looks great” without a punch list does not count.
• You decide. The AIs argue. You ship. If they disagree, pick a side and write the decision into the brief so the next turn starts from that call.

Where a roundtable helps

Copy-pasting between two chats works for one afternoon. It falls apart when the project has a goal, a few decisions, and a third AI for research. A shared room (like AI Roundtable) keeps the notebook and the thread in one link, shows whose turn it is, and lets you paste invites into each AI. Claude can connect more directly. ChatGPT may need a developer-mode connector or a pasted reply. Either way, the draft and the critique stay in the same thread instead of five tabs.

Text and links only is enough for this workflow. If someone generated an image or a spreadsheet elsewhere, paste the Drive or Dropbox link into the thread. The review is about the decision and the words, not about hosting files.

A 15-minute starter prompt pack

Use this on your next landing page, email, or project plan:

• Brief (shared)
• Claude: Builder, version 1 + three questions
• ChatGPT: Reviewer, punch list only
• Claude: version 2 keyed to the punch list
• You: accept, reject, or rewrite the final call in one paragraph

That is peer review. Not a longer monologue from one model. Two minds, one artifact, your decision at the end.
