Prompto is an open-source web application designed to make interacting with Large Language Models (LLMs) simple and efficient. It allows users to fine-tune results, chat or query, and save prompts. Prompto runs entirely in your browser as a Progressive Web Application (PWA) and communicates directly with your chosen LLM provider through LangChain.js integrations.
