Our Short Answer
We use AI writing and research tools as assistants, the same way many writers use spell checkers or search engines. A person decides what each test measures, edits every question and result, checks the facts and takes responsibility for what is published.
Where AI Helps
- Research support: summarising background reading and pointing to original sources, which we then read and check ourselves.
- Drafting support: suggesting first drafts of explanations, alternative wordings for questions and structures for pages.
- Checking: spotting unclear wording, repeated phrases or questions that may be confusing.
Where AI Is Not Used
- Scoring your answers. Tests are scored by fixed rules written into the test, which are explained on each page. No AI model reads or judges your answers.
- Storing or analysing your data. Your answers stay in your browser.
- Inventing facts, people or statistics. We do not publish figures we cannot trace to a source, invented reviewers or AI-generated photos presented as real people.
Human Review
Every page is edited by our editor before it goes live. Facts such as dates, names and research findings are checked against original sources. If AI helped draft a page, a person has still read, changed and approved every line.
Photo Analysis Tools
Our AI photo tools use open-source machine learning models to analyse a photo you choose: Google’s MediaPipe Face Landmarker and Hair Segmenter (Apache 2.0) and an open-source age estimation model from the face-api library (MIT). The models run inside your browser, so your photo is never uploaded. Each tool page explains what it measures, how the result is worked out, how accurate it is likely to be and what it cannot do.
AI-Generated Illustrations
The illustrations on our AI tool pages were generated with Google’s image generation tools (Google Flow), then selected and edited by us. They are stylised drawings, not photos of real people. Images made with Google’s tools can carry an invisible SynthID watermark that identifies them as AI-generated.
