txtai project

txtai is an open-source platform for semantic search and workflows powered by language models. txtai supports indexing text, documents, audio, images and video. Pipelines and workflows enable transforming data with language models. NeuML uses txtai and/or the concepts behind it to power all of our Natural Language Processing (NLP) applications.

List of applications powered by txtai:

  • txtchat - Conversational search and workflows for all
  • paperai - Semantic search and workflows for medical/scientific papers
  • codequestion - Semantic search for developers
  • tldrstory - Semantic search for headlines and story text


paperai project

paperai is a semantic search and workflow application for medical/scientific papers. Applications range from semantic search indexes that find matches for medical/scientific queries to full-fledged reporting applications powered by machine learning.

paperai and/or NeuML has been recognized in the following articles:


Getting started with semantic search

Semantic search is a new category of search built on recent advances in Natural Language Processing (NLP). Large-scale general language models have rapidly pushed the field forward in ways unimaginable only a few years ago. This article gives a brief overview of semantic search and how it contrasts with keyword search.

Getting started with semantic workflows

Semantic workflows transform and find data driven by user intent. Workflows combine machine learning models together to create powerful transformation and processing functions. This article shows how to build workflows with txtai.

Next-generation conversational search

txtchat is a framework for building conversational search and workflows. A set of intelligent agents are available to integrate with messaging platforms. This article gives an introduction to how txtchat works.

What's new in txtai 5.0

txtai 5.0 brings a number of major feature enhancements. The two main components added were semantic graphs and external integrations. This article covers all the changes.
