About
A free library of prompts that work, and a glossary that explains the words around them.
Promptlexity has 96 prompts in 8 categories and 64 glossary terms. Every prompt is written for a task a real person does: rewriting an email, reading an error message, comparing sources, planning a week.
How the prompts are written
Each prompt states a role, the task, the context it needs, and the shape of the answer. The parts you change are written in capitals between double braces, like {{AUDIENCE}}. Every prompt page also shows an example of what comes back and a short note on why the prompt works, so you can adapt it instead of guessing.
How the glossary is written
Every term starts with one plain sentence, then a fuller definition, one concrete example and one mistake people make with it. Terms link to the prompts that use them, and prompts link back.
What it does not do
There are no accounts and no newsletter popups, and analytics only run if you accept them. The site is static files on a global edge network. Search runs in your browser.
For agents and tools
The whole library is available as llms.txt, llms-full.txt andprompts.json. There is also a browser extension that puts the library one click away.
