AI SEO content creator and humanizer for OpenAI and Anthropic models. SEO articles with GPT-5, Sonnet 4.5 & 4o images. Works with Yoast & Rank Math.

Introducing AI Scribe, an SEO AI Writer, Content Generator & Humanizer using OpenAI models (GPT-5) & Anthropic (Sonnet 4.5).
This open-source AI tool is designed to automate your content creation process with SEO and keyword research set from the outset. AI Scribe is not just an AI writer, but also an SEO content optimiser and humanizer that enhances and optimises your content based on tried-and-tested prompts.
With AI Scribe, you can generate SEO optimised content for your website with ease using OpenAI and Anthropic models. This free tool offers customisable options that allow you to tailor your content to your specific needs. All prompts are fully visible and editable at each stage, and these can be changed or saved globally allowing you to fine-tune the entire content creation process. We’ve even built in a range of prompt shortcodes to give you greater control over your content.
[Language]
[Style]
[Tone]
[Title]
[Selected Keywords]
[The Tagline] – using [above/below] for the position
[No. Headings]
[Heading Tag]
[Keywords to Avoid]
Please note: From GPT-4.5, some of these have now been incorporated into the custom instructions, in particular language, style, and tone. This means they are no visible within the prompt itself but will be saved for use within the instructions used.
AI-Scribe is both desktop and mobile-friendly, allowing usability on all devices. Whether you’re looking to create blog posts, articles, or other forms of content, look no further than AI Scribe.
AI Scribe v2.6 brings the addition of GPT-4.5, so it’s now possible to create long-form articles with lighting speed, cost, and efficiency. You can choose between GPT-4.5, OpenAI o3, Claude Sonnet 4 or Opus 4 and also include an SEO-optimised GPT-4o image.

More than just a content generator, AI Scribe is a comprehensive AI content and blog writing solution that integrates seamlessly with your WordPress environment and provides full compatibility and integration with both the classic editor and Gutenberg block editor.
The plugin is also compatible with popular SEO plugins such as Yoast SEO, Rank Math, AIOSEO and SEOPress, providing AI generated meta data which gets auto saved to these plugins along with focus keywords. For page builders like Divi or Elementor, or pages built using widgets or dynamic custom fields like ACF, you can take advantage of the ‘save as shortcode’ option.
AI Scribe offers features such as keyword research, keyword optimisation, structured content generation, and uses a simple wizard-like article builder interface to guide you through the entire process.
The plugin is designed to create natural-sounding, high-quality content optimised for search engines. With v2.0 of AI Scribe, we have now even introduced two Humanizer modes – “Humanizer” and “Humanizer with Personality” – you need to see the result to believe it! Just watch the videos here and here.

This can of course be used in conjunction with WordPress and copied to a post once saved. The U/X isn’t as nice as the plugin and it’s slower to use but it does provide the above benefits.
This plugin requires using the external services of the company OpenAI to work, please make sure to read the Terms of Use and the
Privacy Policy. To use AI Scribe, you will need OpenAI credits and an API Key. Currently, you can get $5 in free credits that can be used during your first 3 months by visiting the Pricing page.
AI Scribe helps users generate SEO-optimised content for their blog posts. Designed to integrate with AI GPT-5 from OpenAI or Claude Sonnet 4.5 from Anthropic, AI Scribe aims to streamline the content creation process by offering editable prompts and suggestions throughout the content writing process.
Please note that AI Scribe is not a commercial plugin, and support is limited to critical issues and suggestions. To get the most out of AI Scribe, users should follow SEO guidelines, personalise their content, and always add value to ensure the best chances of ranking in search engines.

Humanizer Modes
These are modes that accompany style and tone but go far beyond simply asking for “creative” writing or a “formal” style. They add levels upon levels of instructions to help insert nuance that only human writers have been able to provide:
Each mode builds on the previous one, starting from professional and polished (Standard) to human-like (Humanize) and finally to full-on personality-driven content (Personality), depending on the tone you want to strike with your audience.
