About Ax

Who It's For

Ax helps TypeScript developers build AI applications. It's for those creating reliable AI features fast, without complex prompt engineering. If you need to integrate large language models simply and efficiently, Ax makes AI development much easier.

What You Get

Build AI apps quicker and switch between 15+ AI providers easily. Ax automatically optimizes your AI programs, allowing them to improve with training examples. It includes production-ready features like streaming, error handling, and monitoring, making your applications robust from day one.

How It Works

Ax lets you describe your AI program's task by defining inputs and outputs in simple code. For example, tell it to classify a review's sentiment. Ax then automatically creates the best instructions for the AI model. This gives you accurate, type-safe results fast, without manual prompt writing, and works with any major LLM.

Use Cases

Automating Structured Data Extraction from Unstructured Text

Businesses struggle to efficiently process large volumes of unstructured data like customer emails, reviews, or legal documents to extract key information. Ax empowers developers to define precise output schemas, allowing LLMs to automatically extract, type-validate, and structure data, dramatically accelerating data processing and analysis.

Customer ServiceFor: Software Developers

Developing Context-Aware AI Agents with External Tool Integration

Creating advanced AI agents that can perform complex tasks often requires them to interact with external systems, like APIs or databases, to retrieve real-time information or execute actions. Ax provides a robust agent framework that enables developers to easily define and integrate tools, allowing LLMs to intelligently decide when and how to call external functions for more dynamic and capable applications.

Enterprise SoftwareFor: AI Engineers

Streamlined Content Generation and Transformation

Developers often spend significant time on prompt engineering and output parsing when building features like sentiment analysis, translation, or content summarization with LLMs. Ax simplifies this by allowing developers to define clear, type-safe input-output signatures, enabling them to ship reliable content generation and transformation features across any LLM provider 10x faster.

Content MarketingFor: Frontend Developers

Analyzing and Extracting Insights from Multi-Modal Data

Businesses need to understand information presented across different modalities, such as images combined with text, for tasks like product categorization or content moderation. Ax enables developers to build applications that seamlessly process both image and text inputs within a single signature, allowing for the automatic extraction of structured descriptions, categories, and other relevant insights from complex multi-modal content.
