Lumo by Proton

Edit: Lumo has improved a lot, but there are still mistakes, and a high price for what you get. I'm on a duo plan as of now, and hope that there will be adjustments to lumo for paying users. First review: Lots of mistakes, fails to answer, requires additional subscription to protons unlimited plan for unlimited access, very high price compared to what you get.

Fast and knowledgeable, I've been using Lumo as a way to learn about the background, social and political to The Battle of Hastings. I've been able to get excellent, detailed and clear English responses to all my questions and musings around this historical period. Really easy to use in its text-based form. I've not had a chance to try anything else yet. So far, so good. 4-stars and it could be 5-stars but I need to use it for a while. Impressive, frankly.

EDIT: upon reinstalling the app, it loaded correctly after it attempted reloading a couple of times by itself (which is what it did last time, but failed/crashed). now to review the actual product, i've generally enjoyed it, but i'm disappointed with the limit on how long inactive chats last. i didn't expect to lose any, but i did, which is sad. i personally think they should last for at least 30 days (a month) for free members, rather than just 7 days (a week) as another review suggests
