Most companies with a blog now use an AI assistant somewhere in the content process. It drafts outlines, rewrites intros, summarizes research and turns one post into ten social updates. The two names that come up most often are ChatGPT from OpenAI and Claude from Anthropic.
Both cost about the same, both have free plans, and both can write a decent blog post in seconds. So the real question is not “which one can write?” but “which one fits the way your team plans, writes, checks and publishes content?”
This guide compares ChatGPT vs Claude for blog work: writing, research, SEO, images, long documents, integrations and pricing. Every price below was checked on the official OpenAI and Anthropic pricing pages in November 2026.
Quick answer: ChatGPT vs Claude for your blog
- Choose ChatGPT if you want one tool for drafts, research, featured images and repurposing, with custom GPTs your team can share.
- Choose Claude if most of your work is long-form writing, editing in a consistent brand voice, and working with long documents like style guides and content audits.
- Price: the main paid plans cost the same, $20 per month (ChatGPT Plus and Claude Pro). Claude Pro drops to $17 per month on a yearly plan, and ChatGPT also has a cheaper Go plan at $8 per month.
- Best setup for many teams: use one as your main writer and keep the free plan of the other for a second opinion on important posts.
