BraveHeart
Practice the conversation. Then go have it.
What it does
BraveHeart is built for people who freeze in real life. Practice interviews, returning food, or asking someone out with the same kind character every time.

Voice-first mode makes it feel closer to a real talk, and the Courage Tree grows with your practice without ever shaming you for missing a day.Stuck on something that already happened? The “I just froze at...” flow turns real-life awkward moments into custom practice scenarios instantly.

We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
