# Nutrient Java SDK extraction guides

Nutrient Java SDK enables you to extract data from images and documents using advanced optical character recognition (OCR) and intelligent content recognition (ICR) technologies. These guides provide step-by-step instructions on how to extract text and structured data from images using the SDK.

- [Extract data using ICR](/guides/java/extraction/extract-data-from-image-icr.md)
   Extract structured data from images using local ICR with Nutrient Java SDK. Offline processing for air-gapped environments without API calls.

- [Extract data using OCR](/guides/java/extraction/extract-data-from-image-ocr.md)
   Extract text from images using fast OCR with Nutrient Java SDK. Optimized for high-throughput processing and simple text-based documents.

- [Extract data using VLM](/guides/java/extraction/extract-data-from-image-vlm.md)
   Extract structured data from images using vision language models with Nutrient Java SDK.

- [Describe image with Claude](/guides/java/extraction/describe-image-with-claude.md)
   Generate accessible image descriptions using Claude AI with Nutrient Java SDK.

- [Describe image with local AI](/guides/java/extraction/describe-image-with-local-ai.md)
   Generate accessible image descriptions using local AI models with Nutrient Java SDK.

- [Describe image with OpenAI](/guides/java/extraction/describe-image-with-openai.md)
   Generate accessible image descriptions using OpenAI with Nutrient Java SDK.

- [Speed up first ICR](/guides/java/extraction/speed-up-first-icr-by-downloading-requirements.md)
