# MILO

> MILO is an iOS app that gives Siri the brains of frontier AI. On iOS, only
> Siri can be triggered hands-free and system-wide — but Siri itself is limited.
> MILO routes your spoken request to the AI model you choose (GPT, Claude,
> Gemini, and more), so you can ask brilliant models anything hands-free —
> while driving, walking, or with your hands full. Works on iPhone and CarPlay,
> iOS 17.6+. Available now on the App Store.

## What MILO is

For iPhone & CarPlay · iOS 17.6+

**Ask real AI through Siri. Hands-free.**

Say “Hey Siri, ask MILO” from the lock screen, your headphones, or the car — and get a short spoken answer from GPT, Claude, Gemini, or 200+ other models. No app to open. No typing.

## How it works

1. **“Hey Siri”** — Works from the lock screen, AirPods, or CarPlay.
2. **“Ask MILO”** — Siri hands off to MILO. Say your question.
3. **A spoken answer** — Short, read aloud, from GPT, Claude, Gemini or 200+ models.

## Features

- **Ask by voice through Siri** — The only system-wide, hands-free trigger on iOS, routed to the model you choose.
- **Short spoken answers in the car** — CarPlay mode keeps replies brief and reads them aloud, so your eyes stay on the road.
- **Any model, switched by voice** — 7 providers and 200+ models, including on-device Apple Intelligence.
- **Private by design** — Keys live in the iOS Keychain, history stays on-device, no accounts, no prompt analytics.

## Providers (7)

You bring your own API keys (cloud providers) and switch by voice:

- OpenAI — GPT-5.5, GPT-5.4 and mini.
- Anthropic Claude — Claude Opus 4.8, Sonnet 4.6, Haiku.
- Google Gemini — Gemini 3.5 Flash and 3.1 Pro; generous free tier.
- Mistral AI — Large, Medium, Small; European, cost-tiered.
- Groq — Llama, GPT-OSS, Qwen, Kimi; extremely fast inference.

**Free models and API tokens:** Compare free LLM models and providers at [free-llm-models.custats.info](https://free-llm-models.custats.info/), and find free API tokens, trial credits, and provider offers at [freetokens.custats.info](https://freetokens.custats.info/). Choose an offer with API access for a provider MILO supports, sign up on the provider's site, create an API key in its dashboard, then add it in MILO under Settings → API Keys and choose the model. Check the provider's current limits and eligibility before claiming an offer — listings change, not every offer works with MILO, and free tiers may not stay free.

## FAQ

### Why can’t I just use the ChatGPT, Claude, or Gemini apps with my voice?

On iOS, only Siri can be triggered hands-free, system-wide. ChatGPT, Claude, and Gemini apps need you to open them first. MILO connects Siri’s exclusive voice access to any model you choose — ask while driving or hands full.

### Which AI models can I use?

Seven providers you can use today: OpenAI (GPT-5.5), Anthropic (Claude Opus 4.8), Google (Gemini 3.5 Flash), Mistral, Groq, OpenRouter (200+ models), and Apple’s on-device Intelligence. Local Ollama is coming soon and is not available in this release. Switch between the shipped providers by voice.

### How private is it?

Your API keys live in the iOS Keychain and your conversation history stays on your device with SwiftData. There are no accounts and no analytics on your prompts — only the provider you enable ever sees them. On-device Apple Intelligence does not send prompts to a third-party AI service.

### Do I need my own API keys?

For the cloud providers, yes — that keeps costs transparent and under your control, and many offer generous free tiers. Apple Intelligence (on-device) needs no key.

### Is it free?

MILO is a one-time purchase ($8.99 USD in the US; Apple sets the local price in your country — no subscriptions). Download the app and use Apple Intelligence where it is available — no API key needed. For cloud providers (OpenAI, Anthropic, Google, etc.), you bring your own keys and pay the providers directly — many offer generous free tiers.

### How do I install MILO?

MILO is on the App Store — open the listing on your iPhone and tap Buy to download it like any other paid app. No invite or beta sign-up needed.

### Where does it run?

iPhone and CarPlay on iOS 17.6+. It’s available now on the App Store.

## About the maker

On iOS, Siri has true hands-free, system-wide voice. No other assistant has that. The catch: Siri isn’t very smart. The models I rely on — GPT, Claude, Gemini — are locked behind taps you can’t make while driving.

So I wired Siri to those models. I used it every day in the car and on the move. I wasn’t planning to release it.

The wait for a smarter built-in Siri kept slipping. I’d rather give you the bridge today: Siri voice to real AI. That’s MILO.
