usethisprompt.io

As prompt-sharing sites go, usethisprompt.io is free and open-source, and that is what sets it apart. usethisprompt.io is a community platform where people post productivity-focused AI prompts, upvote the ones that work, and discuss them.

Upvotes let the useful prompts rise, so you spend less time sorting through untested ones.

Prompts cover office work, writing and editing, and general productivity, so you will not find a catalogue for every possible use of AI.

If your days involve drafting, organizing or getting routine work done faster, that narrower scope is a plus.

Because the code is open, anyone can look at how the site is built.

Using usethisprompt.io costs nothing.

That fits professionals who want ready-made prompts for ChatGPT-style tools without a subscription.

Think of it as a place to borrow and adapt ideas from other people, with discussion alongside each prompt to help you judge what is worth reusing.
