## What it is
Promptable is a TypeScript/JavaScript library for building LLM-powered applications, providing prompt templating, model providers (OpenAI, Hugging Face, Cohere, Anthropic), embeddings, chains, and tracing. It lets developers compose LLMs with data sources and tools to create chatbots, semantic search, and autonomous agents.

## Use cases
- build a chatbot in typescript
- create a question answering bot with llm
- build semantic search with embeddings
- compose llm chains for ai workflows
- build an autonomous ai agent
- create a writing assistant app
- debug llm app calls with tracing

## When to choose
- you're building LLM apps in TypeScript/JavaScript
- you want a LangChain-style library for the Node ecosystem
- you need to combine multiple LLM providers with embeddings and chains

## When to avoid
- you need a production-stable library — it's explicitly experimental with a changing API
- you work primarily in Python where mature alternatives exist
- the project appears no longer actively maintained

## Facets
- artifact type: library
- maturity: experimental
- function: llm-inference, rag, agent-framework, prompt-engineering, chatbot, sdk
- domain: large-language-models, artificial-intelligence, chatbots, developer-tools
- platform: cross-platform
- tags: llm-app-framework, typescript, embeddings, chains, openai, langchain-alternative, ai-agents, retrieval-augmented-generation, nodejs
