Prompter

Getting AI models to do exactly what you want is as much about the prompt as the model itself — but most people have no structured way to test, compare, and optimize their prompts. Prompter is a tool designed to change that, helping users craft and manage prompts for AI models with a proper workflow for iteration and improvement.

Send prompts to APIs, tweak parameters on the fly, save your prompt history, and run batch tests to compare results side by side — all in one place. Whether you're a developer building AI features or a power user who wants to get more out of every AI interaction, Prompter makes the debugging and optimization process finally feel manageable.
