Promptable.js - Building AI Applications in JavaScript

Promptable.js is a powerful library that allows developers to build AI applications using large language models in JavaScript and TypeScript. With Promptable.js, You can leverage open AI's language models or other providers' embeddings to Create full-stack AI applications.

What is Promptable.js?

A language model captures knowledge from text and uses it to generate responses or make predictions. When a language model has millions or billions of parameters, it is referred to as a large language model (LLM). Promptable.js enables developers to work with LLMs and embeddings, such as those provided by open AI and Hugging Face.

How Does Promptable.js Work?

Promptable.js provides an extensive API for building AI applications with LLMs. It offers features like data storage, data collection, web hooks, and APIs to simplify the development process. With Promptable.js, you can create conversational bots, question-and-answer systems, copywriting applications, email writing assistants, and more.

Use Cases of Promptable.js

• Conversational Bots: Build chatbots similar to GPT-Based conversational models.
• Question-Answering Bots: Create bots that can answer questions based on specific content or podcasts, using semantic search.
• Copywriting Applications: Develop applications that can generate content or assist in writing.
• Personal Assistants: Use LLMs to build personal assistant applications.
• Semantic Search: Implement a search algorithm that understands the meaning behind queries for better search results.
