🧠 Leon is your open-source personal assistant.
What it does
Leon is a free, open-source personal assistant that you can host yourself, allowing it to respond to voice and text commands, automate tasks, and answer questions — similar to Alexa or Siri but running entirely on your own computer or server. Because it runs locally rather than through a company's cloud, your conversations and data never leave your control.
Why it matters for PMs
As consumer and enterprise appetite for AI assistants explodes, Leon represents a growing market signal that users and businesses want privacy-first alternatives to Big Tech voice platforms — a white-space opportunity for products built around data ownership. With nearly 17,000 stars and an active contributor base, it also serves as a ready-made foundation that startups could build specialized assistant products on top of, without licensing fees or vendor lock-in.
