Dropstone is a self-hosted AI assistant with long-term memory that operates across the CLI, chat, SDK, and real-world actions. It can write and ship code, monitor inboxes, control smart home devices, and place phone calls on your behalf. Dropstone runs on open-weight models and can be fully hosted on your own infrastructure, ensuring your code and data never leave your network. Its memory persists across sessions and surfaces, so context taught once is retained indefinitely across all interaction modes.
