What is leon?
Leon is an open-source personal assistant that you install on your own server; you talk to it by voice or text and it handles the tasks you ask for. Its skill (package/module) structure lets you build the features you need or bring in existing ones. Text-to-speech (TTS) and speech-to-text (STT) can be used in cloud or offline mode, so it can be configured to work without any external service. The current 2.0 developer preview is being rebuilt around tools, context, memory, and agent execution.
