TEKLIA opens Arkindex to the world

TEKLIA is pleased to announce that Arkindex, our platform for managing and processing large collections of digitized documents, is now open source under the AGPL-v3 license, starting with version 1.6.0.
This decision aims to foster a larger community of Arkindex users and accelerate the platform's development.


Why go Open Source?

The decision to transition Arkindex to an open-source model stems from our commitment to three core objectives:

  • Accessibility for all: Accessibility is at the heart of this initiative. We believe that everyone, from individual researchers to large institutions, should have access to world-class document AI based processing tools. Open-sourcing Arkindex breaks down barriers and makes it easily accessible to a wider audience.
  • Ensuring longevity and investment security: the decision to open source Arkindex is a strategic move aimed at ensuring long-term durability and ongoing support. This decision reassures users and organizations that their investment in Arkindex is secure. By opening up the code base, we are ensuring that Arkindex remains a sustainable and evolving solution that adapts to technological advances and user needs.
  • Expanding the user community: By making Arkindex open source, we aim to welcome a wider audience of users and contributors. This not only enriches the platform with diverse perspectives but also fosters a strong sense of community among users from diverse backgrounds.


Starting today we offer Arkindex under two editions:

  • Community Edition is the open-source version, you can use it freely for all your open-source projects.
  • Enterprise Edition is available to our customers, with extended support, help and training available. It can scale to hundreds of GPU-enabled servers, and even support super-computers through slurm.
