Where can I find a free library of ready-to-use ChatGPT prompts?
This page is one: 51 copy-and-paste templates grouped into marketing, coding, writing, business, education and research, free, with no sign-up and nothing to install. Each names its deliverable, audience and constraints, with [placeholders] for your details. To keep a library inside ChatGPT itself, the AI Toolbox prompt catalog is free on every plan and inserts with two slashes; the free plan also saves 10 of your own prompts, unlimited on Premium.
How do I use these prompt templates?
Copy a template, paste it into ChatGPT, Claude, Gemini or Grok, and replace every [bracketed placeholder] with your own detail: the topic, the audience, the language, the constraint. The rest of the wording is already specific about the deliverable, so the more precisely you fill the placeholders, the better the answer.
Do these prompts work on Claude, Gemini and Grok as well as ChatGPT?
Yes. They are plain text with no vendor-specific syntax, so they paste into any of the four unchanged. Longer templates that ask for many sections benefit from a model with a large output limit; the model comparison tool lists those.
Can I edit or combine the templates?
They are starting points. Add context under the task, tighten the constraints, or combine two: an outline template followed by a draft template is the usual pairing. The prompt formatter on this site wraps any edited version in a Role, Task, Format scaffold.
How do I save a template so I do not have to copy it every time?
Paste it into the AI Toolbox prompt library. Saved prompts are inserted by typing two slashes in the compose box on ChatGPT, Gemini, Claude or Grok, and each [placeholder] can become a {{field}} that a small form collects at insert time. The free plan holds 10 saved prompts and opens the whole catalog; Premium ($9.99/month or $99 once per module) makes saved prompts unlimited.
What is the difference between this page and the extension's prompt catalog?
This page is a free, no-install list you copy from. The extension's catalog lives inside the chat and inserts with two slashes, keeps your own saved prompts alongside it, supports dynamic fields and chains several prompts into one run (2 chains free, unlimited on Premium). The full catalog is free on every plan.
Why do the templates use [square brackets] rather than {{curly braces}}?
Square brackets are the convention for a value you replace by hand before sending. Double curly braces are what the AI Toolbox prompt library uses for a dynamic field it asks you to fill at insert time; when you save a template there, swap the brackets for braces and the form appears automatically.
Are these templates free, and is anything tracked when I copy one?
Free, with no account or sign-up. Copying puts the text on your clipboard in your browser; nothing you paste elsewhere is seen by this site. The AI Toolbox extension is also free to install, with the prompt library, folders and search on the free plan.
Do these prompts work with the latest models?
Yes. They are compatible with every current ChatGPT model (GPT-6 Astra, GPT-6 Sol, GPT-6 Luna, GPT-6.1 Sol, GPT-6.1 Terra, GPT-5.6 Sol, GPT-5.6 Terra, GPT-5.6 Luna) and with the current Claude, Gemini and Grok lineups. Newer models follow explicit structure at least as well as older ones, so a template that names its deliverable and constraints keeps working across releases.
