Amazon Kendra is a highly accurate and easy to use enterprise search service that’s powered by machine learning. Kendra delivers powerful natural language search capabilities to your websites and applications so your end users can more easily find the information they need within the vast amount of content spread across your company.

Key Benefits of Kendra

Ask natural language questions, get immediate answers

Use natural language questions instead of just simple keywords to get the answers you’re looking for, whether that is a precise answer, an FAQ, or an entire document. Say goodbye to sifting through long lists of links and hoping one has the information you need.


Bring all of your data together in a few clicks

Get rid of information silos. Kendra lets you easily add content from file systems, SharePoint, intranet sites, file sharing services, and more, into a centralized location so you can quickly search all of your information to find the best answer.


Constantly improving search results

Your results get better over time search, because Kendra’s machine learning algorithms learn which results your users find most valuable. You also have the option to fine-tune results by manually adjusting the importance of certain data sources or document freshness.

Get better answers upfront…

Use natural language questions instead of just simple keywords to get the answers you’re looking for. Kendra will connect the dots within your files to return answers, whether that is a text snippet, FAQ, or document. Instead of sifting through long lists of documents to find specific answers, Kendra can provide a suggested answer upfront. See the difference between the search experience before and after Kendra.

…using natural language

Natural language enables you to get more specific answers from anywhere in your data. Ask questions like, “Is the IT help desk open at noon?” or “How do I connect to my VPN?” so you can get more precise answers.

Incremental learning (coming soon)

Kendra actively retrains deep learning models built for your data set and employee usage patterns to improve search accuracy. As end-users interact with search results, Kendra fine tunes its results. This means that if you click on a result or give it a ‘thumbs up’ or ‘thumbs down’, Kendra will learn which results are more relevant and surface those first.

Relevance tuning

Kendra gives you the option to manually tune relevance; you can boost certain fields in your index like document freshness, view counts, or specific data sources. For example, you could boost documents that are not only viewed more often but that are also more recent, like trending news or updates.

Natural language understanding for multiple domains

Kendra uses deep learning models to understand natural language queries and document content and structures for a wide range of internal use cases like HR, operations, support, and R&D. Kendra is also optimized to understand complex language from domains like IT, financial services, insurance, pharmaceuticals, industrial manufacturing, energy, legal, media and entertainment, travel and hospitality, healthcare, HR, news, telecommunications, and automotive. This means that you can ask a question like “Can I add children as dependents on HMO?” and Kendra will provide answers related to your healthcare options.

Amazon Kendra Developer Edition

Kendra Developer Edition provides developers with a lower- cost option to build proof of concepts (POCs) and experiment more with Amazon Kendra. Kendra Developer Edition has the same features as Kendra Enterprise Edition, but limited to 4,000 queries per day, up to 10k searchable documents across 5 data sources, and runs on a single availability zone. Kendra Developer Edition does not offer the scaling options available in the Enterprise Edition. Therefore this edition is ideal for development purposes, not recommended for production.
