Prompt Engineering Tools

This section contains a list of non-IDE tools that are useful for prompting.

Prompt Development, Testing, and Chaining


Large language models (LLMs) are emerging as a transformative technology, enabling developers to build applications that they previously could not. But using these LLMs in isolation is often not enough to create a truly powerful app - the real power comes when you can combine them with other sources of computation or knowledge.

This library is aimed at assisting in the development of those types of applications.


PromptAppGPT is a low-code prompt-based rapid app development framework. PromptAppGPT contains features such as low-code prompt-based development, GPT text generation, DALLE image generation, online prompt editer+compiler+runer, automatic user interface generation, support for plug-in extensions, etc. PromptAppGPT aims to enable natural language app development based on GPT.

PromptAppGPT provides multi-task conditional triggering, result verification, and failure retry capabilities, allowing manual generation tasks that would otherwise require multiple steps to be automated. At the same time, users no longer need to memorise and enter the tedious prompt mantra themselves, and can easily complete tasks by entering only the core necessary information for the task.

PromptAppGPT significantly lowers the barrier to GPT application development, allowing anyone to develop AutoGPT-like applications with a few lines of low code.


The "Prompt generator for ChatGPT" application is a desktop tool designed to help users generate character-specific prompts for ChatGPT, a chatbot model developed by OpenAI.

The Dust platform helps build large language model applications as a series of prompted calls to external models. It provides an easy to use graphical UI to build chains of prompts, as well as a set of standard blocks and a custom programming language to parse and process language model outputs.

It provides a series of features to make development of applications faster, easier and more robust:

  • running multiple completions in parallel
  • inspecting execution outputs
  • versioning prompt chains
  • custom programming language to process data and text
  • API integration for various models and external services


Prompt-learning is the latest paradigm to adapt pre-trained language models (PLMs) to downstream NLP tasks, which modifies the input text with a textual template and directly uses PLMs to conduct pre-trained tasks. OpenPrompt is a library built upon PyTorch and provides a standard, flexible and extensible framework to deploy the prompt-learning pipeline. OpenPrompt supports loading PLMs directly from huggingface transformers. In the future, we will also support PLMs implemented by other libraries.

Prompt Engine

NPM utility library for creating and maintaining prompts for Large Language Models (LLMs).


Relying solely on LLMs is often insufficient to build applications & tools. To unlock their full potential, it's necessary to integrate LLMs with other sources of computation or knowledge and get the pipeline ready for production.

This library is aimed at assisting in developing a pipeline for using LLMs APIs in production, solving NLP Tasks such as NER, Classification, Question, Answering, Summarization, Text2Graph etc. and providing powerful agents for building chat agents for different tasks.


PromptFlow is a free, open-source, low-code tool that allows users to integrate LLMs, prompts, Python functions, and conditional logic to create flowcharts. It includes nodes for:

OpenAI API Calls (any model, including Whisper speech-to-text) Anthropic Claude Calls, Arbitrary Python Code blocks, and Long + Short term history management Database Queries, PostgresML integration, and Text Embeddings HTTP Requests, SerpAPI Google Searches, and ElevenLabs Speech Synthesis Documentation can be found here


TextBox 2.0 is an up-to-date text generation library based on Python and PyTorch focusing on building a unified and standardized pipeline for applying pre-trained language models to text generation:


"ThoughtSource is a central, open resource and community centered on data and tools for chain-of-thought reasoning in large language models (Wei 2022). Our long-term goal is to enable trustworthy and robust reasoning in advanced AI systems for driving scientific research and medical practice."


GPT Index3

GPT Index is a project consisting of a set of data structures designed to make it easier to use large external knowledge bases with LLMs
