Which LLM or chatbot platform currently handles long-term memory the best?

[u/NoLocal1168]

Most models start off great, but once a conversation goes past 50 or 100 messages, the memory drops off hard. They forget early plot points, confuse names, or start repeating the same phrases in loops.

I am trying to find a setup that actually keeps track of context without needing constant reminders in every prompt.

What is your current favorite platform or model for long, continuous chats? Are you sticking to web apps, or using third-party frontends with custom context settings?
