YOUR OWN AI — NO CLOUD

AI that works on your side and does not send your data to the cloud.

We turn recordings into text and documents into tables. You get an assistant that knows your material. It runs on your computer or ours, in the EU. For confidential work: negotiations, clients, patients, contracts.

Who it is for
