Writing

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.

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.

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.

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.

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.
