No, Gospel Library doesn't currently have any APIs that allow it to share data with third-party note apps. It's an interesting idea – you could try sending it as a feature request under Help > Send Feedback (under the three-dots / overflow menu in the top right, in Gospel Library). Out of curiosity, what would you see as the main benefits of sharing notes between Gospel Library and another notes app, as opposed to taking and storing notes only in Gospel Library or only in the other notes app?
