Copilot forgets your codebase every single session.

Yesterday you explained your architecture, your naming conventions, why the payment module is split the way it is. Today you open a new chat and it knows none of it. You explain it again. Tomorrow, again.

Why it happens

Copilot's chat runs on a context window — a fixed-size working memory that exists only for the current conversation. Close the chat, hit the window's limit, or come back tomorrow, and that context is gone. Nothing is broken; the tool was built this way. It has a context, not a memory.

What it costs you

Twice, actually. Your time: the same explanations, re-typed for weeks. And your bill: every re-explanation and every replayed conversation history is tokens, paid again each session. The longer the chat runs, the more history gets re-sent with every single message.

The fix

Give it a memory that survives the session. Juvina Light runs a local memory engine on your machine: what you and your assistant discuss is remembered — decisions, reasoning, history — and recalled when it's relevant, as a compact constructed answer instead of a replayed transcript. Your code and conversations never leave your machine.
