Which kind of AI content tool you need
AI content software splits three ways. General AI assistants (ChatGPT, Claude, Gemini, Rytr) draft, research and edit whatever you ask, one conversation at a time, for a flat monthly price with usage limits. Article generators (Koala AI, Byword, SEOWriting.ai, Machined) are built to produce SEO blog posts in bulk from a keyword, with search data, images, internal links and publishing to WordPress or another CMS, and are priced by words or articles. Editing tools (Grammarly, Wordtune) work on text you have already written: grammar, tone, clarity and rewrites.
For brand copy, ads and campaign writing with voice controls (Jasper, Copy.ai, WRITER, Anyword), see the AI marketing software directory; for briefs and scoring a draft against what ranks, the content optimisation directory.
Publishing AI content and Google
Google’s guidance on generative AI content says it can be particularly useful for researching a topic and adding structure to original content, but that using it to generate many pages without adding value for users may violate its policy on scaled content abuse. It also says AI output may contain inaccuracies and asks site owners to fact-check and review it before publishing. In practice: an article generator saves the typing, not the editing. The guide to programmatic pages without the penalty covers what makes pages at volume worth indexing.

How this directory is built
Every price, plan, free option and trial here was read from the vendor’s own website on the date shown, and each tool links to the exact page it came from. Prices are written as the vendor showed them, in the currency it showed, with how they are billed: monthly, yearly or one-off. Some vendors show prices in a different currency depending on where you are, so check the source before you buy.
There are no ratings, rankings or paid placements, and no affiliate links. Tools are listed A to Z. Where a vendor does not publish a price, the listing says so rather than quoting a third party. Prices are rechecked every quarter; the date on each listing is the last time it was confirmed. If a listing is wrong or out of date, tell me and it will be corrected.
