Your AI assistant, explained.
One assistant that can see, search and act across WhatsApp, Telegram, Instagram and Messenger — connecting to all four from your phone, not from our servers.
Its day job isn’t writing your messages. It’s making sure nothing said in them gets away from you. Here is what it actually does, what it can reach, and what runs where.
Four things it does. One page each.
Read them in order for the whole argument, or jump straight to the one you came for — each is a focused, self-contained explanation.
The unit that makes any of it repeatable — the two kinds, the four ways to fill your library, the Knowledge Base — and the tools a Skill reaches before it answers.
Summary triages every unread chat across all four networks, Analyze files what a thread contained into Calendar and Reminders, Smart Reply writes three drafts you pick from, and Skill runs an entry from your own library.
For work bigger than one reply — a standing conversation on Apple Intelligence or Claude that sees only the chats you scope, with every control set per conversation.
Apple Intelligence on your iPhone by default, Claude when a task needs more — when to reach for which, how you switch, and what each one costs.
“Why would I want AI writing to my friends?”
Mostly, you wouldn't — and that isn't what this is for. Five of the six things the assistant produces aren't messages at all. Its job is the work around the conversation: finding the thing you were sent, remembering what you promised, turning ninety messages into a calendar entry, answering the question you'd otherwise leave the app to look up. Smart Reply is where most people first meet it, not the reason it exists — and nothing it writes reaches anyone until you have read it and tapped send.
Where everything runs.
All four parts, audited in one view — each surface, what runs where, and what it can see. Only one path here touches a Flowbie server: an AI Credit request, forwarded to Anthropic and metered, never stored.
| Surface | Where it runs | What it can see |
|---|---|---|
| Skills & Knowledge Base | On device | Your instructions, sliders, and attached documents |
| Analyze & Summary | On device · Claude if you enable it | The conversations you run it on |
| Skill button in a chat | On device · Claude if you enable it | Only the conversation you’re in |
| Agent chat | Claude — AI Credit or your own key | Only the chats you scope — locked chats never |
| Tools | On device, Apple frameworks | Only what each tool needs, behind iOS permissions |
| Apple Intelligence | On device | The scoped context; nothing leaves your iPhone |
| Claude | Anthropic cloud — AI Credit or your own key | Only what you send; your own key goes direct, AI Credit relays without storing |
| Action cards | On device | Nothing is sent or created until you confirm |
| Skills Marketplace | Browsing only | Skill definitions — never a message |
