I remember a few projects like this, the first I saw was called Savant Recall in 2014. But it failed to be selected for YC, so was set free as open-source. Napster co-founder Ritter picked it up, renamed it Atlas Recall (2016), gave it a new UI, secured $20M in funding. A year later it was suddenly shutdown. On LinkedIn says "acquired by Xinova". Another one I'd heard of was called Apse (2019).
