I built Cinnamon for my family because the majority of agents are focused on personal tasks and I wanted both personal and shared contexts, with easily managed memories/facts. It uses Gemini models, ADK, and runs entirely on Google Cloud. Happy to answer any questions!
Just added shareable artifacts yesterday (you can share the results of a task publicly), which can be anything from a marketing plan to a playable HTML game https://getcinnamon.ai/artifact/dj4tabdq
