Description

Jarvis AI Assistant is a voice-first AI you actually talk to - not type at.

Tap once and just talk. Ask it about your day, think a decision out loud, or just chat. It listens, replies out loud, and remembers what matters to you - your name, your projects, the people in your life - so you never have to re-explain yourself.

WHY JARVIS IS DIFFERENT

Bring your own key, own your data. Jarvis uses your own Google Gemini API key. Your voice goes directly from your phone to Google - never through our servers, never stored by us. No account, no login, nothing to sign up for.
It actually remembers. Tell Jarvis something once - a preference, a project, someone important to you - and it carries that into every future conversation. All stored only on your phone.
Talks like a person, not a script. Natural, low-latency voice conversation powered by Gemini Live - interrupt it, change the subject, it keeps up.
Genuinely useful, not a toy. Ask about your calendar, look someone up in your contacts and call or text them, check the weather wherever you are - Jarvis asks for each of those permissions only the moment it actually needs them, never upfront.

WHAT YOU NEED

A free Google Gemini API key (get one in about a minute at ai.google.dev) - that's it. No subscription to Jarvis, no account.

Built by one person, not a company. If it's useful to you, a rating helps
more than you'd think.
