GAN (Generative Adversarial Network)

Two competing neural networks that generate realistic outputs.

Generative AI

AI that creates original text, images, audio, or video. Used in Wordflow for marketing content.

Generative Pre-Trained Transformer (GPT)

A family of LLMs used in Wordflow.

Gradient Descent

An optimisation method used to train models by minimising error.

Graph Neural Network (GNN)

Neural networks designed to work on graph data.

Ground Truth

Verified data used to validate AI models.

Generative Engine Optimisation (GEO)

The practice of optimising a brand's content and online presence to be accurately surfaced and cited in AI-generated answers. GEO is the AI-era equivalent of SEO — shifting focus from search engine rankings to visibility in AI-powered answer engines like ChatGPT, Perplexity, and Google AI Overviews.

GEO Writer (Wordflow)

Wordflow's flagship content generation tool, built on AI search frameworks. GEO Writer produces brand-consistent, citation-ready content directly from campaign data and Action Hub recommendations. Available on Starter, Pro, and Agency plans.

Gemini (Google)

Google's family of multimodal AI models, used to power Google AI Overviews and other Google products. As the model underlying Google AI Overviews, Gemini's citation behaviour directly affects how brands appear in AI-enhanced Google search results. One of the seven AI platforms tracked in Wordflow AI Search Campaigns.

Google AI Overviews

AI-generated summaries shown at the top of Google search results, powered by Gemini. Google AI Overviews appear for a growing share of queries — synthesising answers from multiple sources and citing the websites they draw from. One of the seven AI platforms tracked in Wordflow AI Search Campaigns, and one of three platforms covered in the Wordflow Free Scan.

Grok

An AI assistant developed by xAI, integrated with the X (formerly Twitter) platform. Grok has real-time access to posts and conversations on X, giving it a distinctive data source for current events and brand mentions. One of the seven AI platforms tracked in Wordflow AI Search Campaigns.
