Why RubyGem?
Unlike cloud-based AI apps, everything happens locally on your iPhone. Your notes and conversations never leave your device, giving you modern AI capabilities with complete privacy.
Note: The performance of the local LLM depends on your iPhone model. Currently it is powered by a 1B parameter model, which requires stronger prompting to perform well.
