Next step
Want the skill, not just the tool?
Every tool here does one task. Coursiv teaches the underlying skill in short, practical lessons: prompting, AI for Excel, AI for your role, and a CPD-accredited AI certificate program.
A short quiz first. No payment details.
How these tools work
In your browser
All five tools compute on this page. Your text never leaves your device, so you can paste real work into them.
Rule-based, not a chatbot
Each tool encodes a method: a scoring rubric, a recipe library, a task rating scale, a tokenizer, a pattern set. Same input, same answer, every time.
A path to the skill
Each result ends with what to learn next, because a tool solves one instance and a skill solves the category.
