AI Writing Tools

Write for Humans. Rank in AI.

Generative Engine Optimisation (GEO) is the practice of writing content that AI systems can extract, cite, and recommend. These tools help you measure and improve your content across both traditional SEO and AI visibility dimensions — entirely in your browser, no account required.

What is GEO — and how is it different from SEO?

SEO optimises for search engine crawlers and ranking algorithms. GEO (Generative Engine Optimisation) optimises for AI systems — ChatGPT, Perplexity, Google AI Overviews, Claude — that extract and summarise web content in their answers.

The key difference lies at the sentence level. Search engines rank pages by authority and relevance; AI systems go further — they identify candidate pages and then extract the most relevant sentences to include in a generated answer. A page can rank #1 in search and still never appear in an AI answer if its sentences are not self-contained, entity-rich, and clearly structured. Optimising for AI visibility means writing content that works at both the page level and the sentence level.
