> “Write blog posts with AI”. Ranked by expert consensus and what people use now; affiliate links never change the order.

For blog posts you want two things: a model that drafts and restructures, and a check on grammar and tone before you publish. Claude is strongest on long drafts and nuanced edits, with a free plan; ChatGPT adds web search for research; Gemini draws on your Gmail, Docs and Drive files. Grammarly checks every line wherever you type. Sudowrite is built for fiction, so it suits novelists more than company blogs.

## Questions

### Claude, ChatGPT or Gemini for writing a company blog?

All three draft a solid first version, so pick by where your material lives. Gemini works with Gmail, Docs and Drive, which helps if your notes and briefs sit there. ChatGPT searches the web, useful for posts that need current sources. Claude handles long documents well, so it suits turning a long interview or report into an article.

### Can I write blog posts with AI without a subscription?

Claude has a free plan, and Grammarly's basic corrections are free. That pair covers drafting and a final proofread for a few posts a month. Gemini has a free tier for everyday use too. Once you publish weekly, the higher limits of a paid plan start to matter.

### I already use Grammarly. Do I need an AI assistant as well?

Grammarly checks grammar, spelling, tone and clarity, and paid plans add full rewrites. It works on text you have already written. An assistant such as Claude or ChatGPT helps earlier: outlining, drafting and restructuring a post. Many writers draft with an assistant and finish in Grammarly.

### Will Google penalise blog posts written with AI?

Google's guidance targets low-value content made mainly to rank, whatever wrote it. A post that adds your own data, examples and opinions is fine, AI-assisted or not. A post that repeats what every other page says will struggle either way. Use AI for structure and drafts, and add the parts only you know.

### Is Sudowrite any good for business blogging?

Sudowrite is built for fiction authors, with tools for plots, scenes and a Story Bible that tracks characters. It starts at $10 a month. For a company blog, a general assistant fits better. Pick Sudowrite if you are also writing a novel.
