All good things come to an end, some sooner than expected. Ambiverse is no more, but the Ambinauts are proud of their journey through the Ambi-Verse, and also excited about future adventures!

We have a parting gift for you: Our Ambiverse Natural Language Understanding suite (AmbiverseNLU) is now open sourced.

Thank you for exploring the Ambi-Verse together with us.

P.S. The developer portal will continue to operate for some time without any support, and will be discountinued in the future.

Ambiverse Natural Language Understanding API extracts entities from unstructured text, enabling a more precise transformation of texts into actionable, measurable, and easily accessible knowledge. Entities are identified by types such as person, location, organization, or product, and linked to the Wikipedia-derived YAGO knowledge graph.
