However,\nthese products perform a specific text and analysis function. Depending on your\nuse case, these products might provide the specific capabilities you need.\n\nConvert images to text\n\nYou can convert content in images to text using either:\n\n- [Enterprise Document OCR](/document-ai/docs/processors-list#processor_doc-ocr).\n- [Cloud Vision API](/vision) (using the `TEXT_DETECTION` or `DOCUMENT_TEXT_DETECTION` enums). See:\n\n - [Cloud Vision API Quickstarts](/vision/docs/quickstarts)\n\n - [Detect text (OCR)](/vision/docs/ocr)\n\n - [Detect handwriting (OCR)](/vision/docs/handwriting)\n\n - [PDF/TIFF Document text detection](/vision/docs/pdf)\n\nDetect visual artifacts\n\nYou can use [AutoML Vision object detection](/vertex-ai/docs/training-overview#object_detection_for_images) to\nconvert sections of images into text documents. For details, see [Image data](/vertex-ai/docs/start/automl-model-types#image).\n\nClassify documents\n\nWith document plain text and running OCR beforehand, you can categorize and label\ndocuments using the following products:\n\n- The pretrained Natural Language API helps you classify content using a generalized list of categories.\n- Use AutoML Natural Language classification to create a custom machine learning model, and classify content with your own category labels.\n- While there may be exceptions, AutoML Vision classification is not\n generally recommended for document classification because its tends to be less\n accurate than text-based methods. However, you can use it for classifying image content.\n\n - This is not generally a recommended method for classification of documents, as its accuracy tends to be less than text based methods, but there may be exceptions\n\n|--------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------|\n| **Natural Language API** | - [Cloud Natural Language API Quickstarts](/natural-language/docs/quickstarts) - [Classifying content](/natural-language/docs/classifying-text) |\n| **AutoML Natural Language classification** | - [Text model type](/vertex-ai/docs/start/automl-model-types#text) |\n| **AutoML Vision classification** | - [Image model type](/vertex-ai/docs/start/automl-model-types#image) |\n\nAnalyze and extract entities\n\nYou can identify known entities in documents (proper nouns such as public\nfigures, company branding, and so on) and entities that follow common patterns\nsuch as phone numbers and addresses with using\n[Form Parser](/document-ai/docs/processors-list#processor_form-parser) or any of the\n[pretrained processors](/document-ai/docs/processor-overview) for your use case.\n\n- You can also use the Natural Language API to identify common, public entities.\n- AutoML Natural Language products are for entity extraction.

Provides a document translation API for directly translating documents in formats such as PDF and DOCX. See [Translate documents](/translate/docs/advanced/translate-documents).\n- [Workflows](/workflows): Combines Google Cloud services and APIs to build reliable applications, process automation, and data and machine learning pipelines.\n- [AppSheet Automation](/appsheet/automation): Creates custom automations and applications with an open cloud.\n- [Drive scanner by Google Drive](https://support.google.com/drive/answer/3145835?&co=GENIE.Platform%3DAndroid): The Google Drive Android app lets you scan and upload documents to Google Drive and offers intelligent title suggestions powered by Document AI.\n- [Google Translate](https://translate.google.com/): This service instantly translates words, phrases, and web pages between English and over 100 other languages.\n\nFind a partner\n\nTake advantage of our growing partner ecosystem to help you create and manage\nyour document analysis solution.
