Why should I use this app over apps like ChatGPT or Gemini?

PromptHQ is not a replacement for ChatGPT or Gemini, or even an AI chat app. It is a tool to help you use LLMs better — by evaluating and iterating on different LLMs and prompts and settings like temperature, thinking budgets, etc.

Why is AI fluency important?

The AI revolution is like the computer revolution — if you stuck with pen and paper and faxes, you got left behind. Read more about how the leading companies are already asking their employees to get AI-fluent.

Is prompting LLMs really that hard?

It is different from Google Search where you can write a terse query but do most of the work afterwards trying to make sense of the search results. With LLMs, a little upfront work in writing a good prompt can make it do all the work for you.

Who is the team behind PromptHQ.run?

PromptHQ.run was created by the team at GnoDesk, a company founded by Umang Jaipuria, former tech and product executive at companies like Twitter, Amazon, and Plaid. This was one of our most useful internal tools and we decided to make it publicly available.
