About This Tool

Overview

AI Productivity Tools

Say you have a customer email prompt that works half the time: GPT Prompt Tuner lets you run versions of it side by side and keep the one that behaves.

It is a prompt engineering tool for testing and refining GPT prompts in parallel, so you compare outputs instead of guessing which rewrite helped.

Pricing is freemium, with a 7 day free trial on each paid plan.

The Self Driving plan costs $4.99 a month and gives unlimited tunings and messages, but you must supply your own OpenAI API key and pay OpenAI directly for usage.

The Monthly plan is $9.99 and includes 4000 messages a month, unlimited tunings and unlimited prompts.

The Yearly plan works out to $5 a month.

An Enterprise tier is available on request.
