ChatGPT Reviewed My PR and Wrote Better Comments Than I Did - Here’s How AI Is Reshaping Code Reviews in 2025
The age of solo coding is over. In 2025, artificial intelligence is not just a tool for writing code.
Tools like ChatGPT, Claude 4 Opus, and Gemini Code Assist are changing how developers think, build, and ship. I didn’t realize how much until I watched Claude annotate my pull request - and leave feedback better than I would’ve written myself.
The age of solo coding is over. In 2025, artificial intelligence is not just a tool for writing code – it’s a second set of eyes, a rubber duck, a code reviewer, and sometimes… a better teammate than your team.
From comment quality to line-by-line reasoning, here’s what happened when I asked Claude, ChatGPT, and Gemini to review my code – and what it means for the future of software engineering.
My Usual Code Review Process (Before AI)
As a mid-level backend engineer, I typically spend 4–6 hours a week reviewing PRs: scanning for logic bugs, style issues, missed edge cases, or unclear variable naming. It’s cognitively exhausting. When it’s my own PR, I often skip nitpicks or miss subtle flaws.
So one day, as an experiment, I fed the PR into Claude 4.
The results blew me away.
Claude’s Review Comments Were Scary Good
Claude didn’t just say, “rename this var.” It structured comments like a thoughtful senior dev:
- Flagged an async function that lacked a timeout guard
- Suggested more descriptive error messages for external API failures
- Asked why I used Promise.allSettled() instead of Promise.all() - with a subtle catch around error masking
Even better: the comments were polite, educational, and explained trade-offs. One team member replied, “Is this Claude or our staff engineer?”

How Claude Compares to ChatGPT and Gemini in PR Reviews
I ran the same prompt through ChatGPT-4o and Gemini Code Assist. Here’s what I found:
Each tool brought a unique layer of insight. But Claude stood out for thoughtful, code-aware commentary - the kind you’d expect from an experienced human reviewer.
Chatronix Let Me Compare All AI Comments Side-by-Side
Instead of switching tabs and rerunning prompts, I now do all this inside Chatronix. It’s a multi-agent workspace where Claude, ChatGPT, and Gemini live together in harmony.
With Chatronix, I:
- Run the same PR review prompt across all models
- Compare output in one view
- Save and reuse my prompt templates for consistent feedback
- Export suggestions into GitHub comments with one click
If you're managing multiple AI tools and want a clean way to test, compare, and integrate feedback - this is the productivity boost you didn’t know you needed.
Try Chatronix's AI review suite and run Claude, ChatGPT, and Gemini like a full-stack code review team.
What Prompt I Used to Get Claude’s Feedback
Here’s the actual prompt I used:
You're a senior backend engineer reviewing a pull request. Please:
- Point out bugs, performance issues, or architectural flaws
- Suggest code clarity or naming improvements
- Explain trade-offs if relevant
- Keep a respectful tone, like you're mentoring a peer
Here's the code diff: [paste here]
Claude didn’t just reply with suggestions. It structured comments using Markdown with inline quotes from my code. One of them even ended with: “Nice touch on the retry logic - clean and thoughtful.”
What Changed in My Team After That
After I posted Claude’s comments to the PR thread (with attribution, of course), something weird happened:
- My junior teammate asked: “Can Claude review mine too?”
- My manager added a prompt library to our internal wiki
- Our product lead started using Gemini to translate tech debt tickets into sprint-ready items
Now, AI is part of our workflow. Not as a crutch, but as a co-reviewer, idea partner, and teacher.
Are AI Reviewers Better Than Humans?
Not yet. But they are fast, consistent, and immune to burnout. And if you train them right (with good prompts), they make your human reviewers better, too.
Here’s how I now structure reviews:
- Run PR through Claude + ChatGPT + Gemini
- Combine best suggestions
- Review human comments with new insights
- Final approval still done by people
It’s a hybrid system - and it works.
Final Thoughts: The Future of PR Reviews Is Already Here
What started as a fun test turned into a habit. Claude doesn’t just review my code - it pushes me to write better code in the first place. ChatGPT catches what I miss, Gemini adds the web-scale context.
If you’re still reviewing code without AI - you’re falling behind.
