About Prompto

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.

How to Use

Prompto runs in your browser. Choose an LLM, adjust settings like temperature, and use the chat, notebook, templates, or arena features to interact with the LLM. Settings and data are stored locally in your browser.

Key Features

  • Multiple LLM support via LangChain.js
  • Temperature control for response adjustment
  • Chat interface for conversational context
  • Notebook for isolated prompts
  • Templates for saving and reusing prompts
  • Arena for comparing LLM responses
  • Discussion for creating conversations between AI personas

Use Cases

  • Interacting with different LLMs through a user-friendly interface
  • Fine-tuning the creativity and predictability of LLM responses
  • Creating and saving prompts for later use
  • Comparing the outputs of different LLMs side-by-side
  • Engaging in dynamic conversations with multiple AI personas
