Same prompt, side by side

Write a short, warm thank-you note, under 80 words, to my neighbour Margaret, who watered my tomato plants and fed the cat while I was away for a week.
Claude 5 Opus30s

Dear Margaret,

Thank you so much for looking after everything while I was away — the tomatoes are thriving and the cat seems perfectly content, so you clearly worked your magic. It's such a comfort knowing a kind neighbour is keeping an eye on things. I really appreciate it.

With warm thanks, [Your name]

That's about 65 words — happy to tweak the tone or sign it off with your name if you'd like.

GPT 5.6 Sol15s

Here's a warm note for Margaret:

Dear Margaret,

Thank you so much for looking after everything while I was away. The tomato plants are thriving thanks to your careful watering, and the cat clearly enjoyed your company — she seems almost disappointed I'm back! It's such a comfort knowing a kind neighbour is just next door. I really appreciate it, and I hope you'll let me return the favour sometime.

With warm thanks, Pat

That's 76 words — want me to tweak the tone, or save it as a Gmail draft?

Our take: Both notes are ready to send. Claude's is tighter; ChatGPT's adds a warm detail about the cat and signs it with the name it remembered from earlier chats.

Or use both, in one place

Claude Pro and ChatGPT Plus cost $40 a month together. In Chatly both sit in one model picker, with Gemini, Grok and more. Every answer on this page came from it.

Common questions

Is Claude better than ChatGPT?

Neither wins everywhere. Claude is often preferred for writing and long documents; ChatGPT makes images and has a cheaper paid step. On our four everyday prompts they were close, which is why Chatly gives you both in one model picker.

Which is better for coding?

Both are strong. Claude has Claude Code and ChatGPT has Codex, and on our short coding test they wrote the same correct function.

Can Claude make images?

No. ChatGPT can make and edit images in the chat; Claude cannot generate images.

Which is cheaper?

ChatGPT Go costs $8 a month, the cheapest paid step. The main plans, Claude Pro and ChatGPT Plus, both cost $20 a month.

Can I use Claude and ChatGPT without paying for both?

Yes. Chatly puts Claude and GPT models in one model picker, along with Gemini, Grok and others, so you can switch between them in the same place.

How did you test them?

We sent the same four prompts to Claude 5 Opus and GPT 5.6 Sol inside Chatly on 29 September 2026 and show the answers exactly as they came back.
