About Juvina
Juvina provides persistent, local AI memory for GitHub Copilot and Claude Code within Visual Studio Code. It operates entirely on the user’s machine, storing memories locally without sending data to external servers. The tool uses a token-efficient engine that reduces costs over time by maintaining context without repeated prompts. It supports both rolling 7-day memory and permanent memory options, with pricing tiers based on usage. Juvina is built on .NET and runs within the user’s tenant, ensuring data remains under local control. The system introduces Merlin, an AI character whose responses are generated entirely from stored memories, demonstrating the engine’s ability to construct contextually accurate answers.
