At first it will only work with the FamilySearch Family Tree. We hope to expand it to other trees in the future. At first, the entry point will be via the website as shown in the video, but we will probably update the Chrome Extension to just have one link to the Research Assistant as opposed to the three BMD links.
We would like to get your feedback on this. Would you use it? What could make it better? What do you hope it will do?
