Opal can analyze audio recordings, various file formats, YouTube videos, and any other documents you upload.
Opal is powered by OpenAI's GPT-3.5 and GPT-4 large language models.
Your files are analyzed using OpenAI's secure API. All generated notes and data are stored on our private servers and remain inaccessible to others.
