Promptbook

Gaurav Singh built Promptbook because he saw something obvious: everyone is using AI, but almost nobody knows how to actually talk to it. The difference between a mediocre prompt and a great one can mean the difference between garbage output and something actually useful—and Promptbook is here to close that gap. It's a platform designed to help people master the art of AI interaction, whether you're prompting ChatGPT, Claude, or any other model.

The AI prompting space is getting crowded, but here's the thing—most people are still writing prompts like it's their first day on the internet. Promptbook aims to change that by teaching users how to structure their inputs for maximum output quality. It's the kind of tool that makes you realize you've been doing it wrong this whole time. Gaurav launched on Product Hunt and is building in public—exactly how you should do it in 2025.

Promptbook is based in India and they're looking for early users and feedback. If you're spending more than 10 hours a week prompting AI and getting mediocre results, this might be the tool that finally makes you dangerous.
