Features

Built for natural conversation.

Everything you need from a voice assistant. Nothing you don't.

Push-to-talk

Tap the orb, speak naturally. Ballsy listens, transcribes, and responds in your voice. Hands-free when you need it.

Streamed answers

Replies arrive token-by-token over WebSocket. You see the thought form in real time — no progress bars, no waiting.

NVIDIA NIM

Built on Llama 3.1 Nemotron via NVIDIA's inference platform — fast, capable, and tuned for conversation.

Type or speak

Voice not appropriate? The text input works just as well. Switch between modes mid-conversation.

Conversation memory

Ballsy remembers the thread. Ask a follow-up without repeating context — your last 20 exchanges stay in scope.

Privacy-first

Speech recognition happens in your browser. Conversations aren't stored on our servers. No accounts, no tracking.

How it works

From voice to answer in three beats.

01 ─ Allow mic

Grant microphone access

One-time browser prompt. Required for voice; text input works without it.

02 ─ Tap & speak

Press the orb, ask anything

Speak naturally. Ballsy transcribes locally and sends only the text.

03 ─ Hear the answer

Streamed reply, spoken back

The response appears as it's generated and is read aloud automatically.

FAQ

Questions, briefly answered.

Why is the first response slow?
On serverless platforms the backend cold-starts, which can take 15–30 seconds the first time. Every reply after that is fast. If it ever stalls again, it's just napping — give it a beat.
Which browsers are supported?
Voice input uses the Web Speech API: Chrome, Edge, and Safari work best. Firefox can type to Ballsy fine, but voice-input is limited.
Do you store my conversations?
No. The session lives in your browser's memory and disappears when you close the tab. Speech recognition happens locally; only the text is sent to the model.
Is there a keyboard shortcut?
Yes — press Space to start and stop listening. Press Esc to interrupt Ballsy mid-sentence.
Can I use Ballsy on mobile?
Yes. The app is responsive and microphone access works on iOS Safari and Android Chrome. Add it to your home screen for an app-like feel.
