About
Vermilion is a voice-first AI assistant that speaks back — and illustrates its answers.
Ask about the nearest coffee shop, the weekend forecast, or the tallest mountain on each continent. Vermilion answers out loud and adds maps, charts, and images as you talk — so you see the answer, not just hear it.
TALK NATURALLY
Speak as you would to a person. Vermilion replies in a natural voice, with several to choose from. Ask follow-ups, change direction, think out loud.
ANSWERS YOU CAN SEE
• Maps — find places and travel times, powered by Apple Maps
• Charts — compare data at a glance
• Images — see what you're asking about
WEATHER
Current conditions and forecasts anywhere, powered by Apple Weather.
97 LANGUAGES
Speak and listen in any of 97 languages, and switch languages mid-conversation.
EVERYWHERE YOU ARE
• CarPlay — talk with Vermilion in your car (requires iOS 26.4 or later)
• Controls — add Vermilion to Control Center or the Lock Screen, or assign it to the Action button
BUILT FOR PRIVACY
• No account — open the app and start talking.
• Your storage — conversations are saved in your own iCloud account, never on Vermilion's servers.
• No profiling — each conversation stands alone. Your chats aren't combined to build a picture of you.
FREE & PRIVATE PLANS
Every feature works on both plans. The difference is training:
• Free — uses Google's free AI service. Google may use your conversations to train its AI models.
• Private — your conversations are never used to train AI models. Your subscription pays for the AI service that makes this possible.
Vermilion is built by a solo developer — your subscription keeps it going.
