AI Mastery Hub

Prompt lessons for AI chats

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Learn to write prompts that get better answers from Claude, ChatGPT, Gemini and Grok. Short, friendly lessons with a live prompt checker. Not a language app. Works with the major AI platforms: Claude by Anthropic, ChatGPT by OpenAI, Gemini by Google and Grok by SpaceXAI. AI Mastery Hub teaches you to write prompts that get better answers, in short, friendly lessons. Every good prompt has five parts: context, persona, task, format and constraints. Type a prompt and watch each part light up in its own colour, so you can see what is missing before you send it anywhere. WHAT YOU LEARN • What AI chat really does, and why its answers need a check • The five parts of a strong prompt • Emails, messages, summaries and spreadsheet formulas • Keeping private details out of your prompts • Working from your own files and long documents • What happens to what you paste into an AI tool • When AI can act for you, and how to stay in control • Getting current answers with sources you can check • Choosing the right AI tool for the job • Spotting fake AI apps and voice scams PRACTISE FOR REAL Connect your own Anthropic, OpenAI, Google or SpaceXAI key and send your prompt to a real AI model. Your key stays in your phone's secure storage and goes only to the provider you choose. API use is billed by that provider. Each provider sets its own age rules for API keys. Google (Gemini) and SpaceXAI (Grok) require API users to be 18 or older. Check your provider's terms before you connect a key. FREE TO START Modules 1 to 3, the prompt highlighter, the prompt library and a plain English glossary of AI words are free.
