If you're looking for a full-featured website for genealogy research, MyHeritage is a good option. It lets you create and manage family trees, explore your ancestry and take DNA tests for genetic information. With more than 20.3 billion historical records, you'll have a lot of data to draw from. MyHeritage also offers smart matches, deep nostalgia technology and collaboration tools, so it's good for both beginners and more advanced genealogists. It also offers a 14-day free trial, so you can try it out.
Another possibility is AnyQuestions.ai, though it's geared more toward information retrieval and AI-boosted document analysis. It can handle a variety of file formats and can quote answers from documents, which could be useful if you need more detailed information from historical records. But its purpose is for learning and studying, not necessarily for a specific genealogy research project.
