Promptable

Build fullstack AI apps in Typescript/Javascript.

What is this?

Promptable is library that enables you to build powerful AI applications with LLMs and Embeddings providers such as OpenAI, Hugging Face, Cohere and Anthropic. It provides a flexible and extensible API that makes it easy to compose LLMs with data and tools to build complex applications quickly and easily.

With Promptable, you can combine LLMs with other powerful tools and data sources, such as databases and APIs, to create a wide range of AI applications.

What is LLM?

An LLM is a Large Language Model. It is a model that can generate text given a prompt. It is a type of AI that can be used to generate text, answer questions, and more.

What is an Embedding?

An Embedding is a vector representation of a piece of text. It is a type of AI that can be used to find similar pieces of text, search for text, and more.

! Right now the library is in early development and is very much experimental. Don't use this in production yet! The API is subject to change as we get feedback.

What's inside?

This a Turborepo monorepo of tooling for Typescript developers building LLM apps.

It uses pnpm as a package manager and includes the following packages/apps:

packages/promptable: The Promptable Library for building LLM apps in Typescript / Javascript!
examples: Examples using the Promptable.js library!
apps/docs: The Promptable.js Docs
apps/web: A nextjs app for visualizing Promptable.js steps.
apps/nextjs-promptable: A nextjs app starter kit with prebuilt features (ChatBot with Streaming, QA Bot etc.)

Contributing

Install and Run

Then to install run (at the root)

pnpm i

To install package in a single workspace


pnpm i <package> --filter <workspace>

First copy the apps/web/.env.example file to apps/web/.env.

Then, To develop all apps and packages, run the following command:


cd my-turborepo
pnpm run dev

This will start watching the files for changes.
