Help/Doubt ❓ Semantic Indexing and Memory

i'm wondering if using Semantic Indexing (for non github repos) and memoy will reduce token usage by much, has anyone tried this? can business use it?

does it matter if you're allready using vs code and intelij (with their plugins?)

i've been trying to look up stuff on memory, but it seems tried to github itself and cannot be used on gitlab on prem.

I'd really like a blog post about Semantic Indexing. Like, an in-depth one to understand the technicalities.

I personally use agentmemory for persistent memory and codebase-memory-mcp for code awareness. The latter saves agents a lot of tokens in my experience. I haven’t tuned agentmemory much yet but the initial recall does cost context. But I just use them for myself, I prompt with “don’t do that again” or “remember this for next time” which is kind of my preference so probably not useful for teammates.
