Fern Browser running on Apple Watch

Inside the app

Built for the watch — not shrunk down from the phone.

Every screen designed around the wrist: glance-able, one-handed, and lit up with an animated aurora behind the glass.

Search screen

Search

Type or dictate, hit go.

AI assistant chat screen

AI Assistant

Pick a model, ask anything.

Bookmarks screen

Bookmarks

Saved sites, one tap away.

Features

Everything you need. Nothing you don't.

Search anything

Type or dictate a query and Fern opens the results in Apple's secure web view. Your search history stays on the watch.

Chat with AI

Pick from DeepSeek, Llama, Gemini, Claude, GPT-4o, and more — through OpenRouter. Switch models with one tap. Free models included.

Your keys, your watch

API keys live in Apple Keychain, locked to this device. AutoFill from the Passwords app means you never type your key by hand.

Bookmarks & history

Save what you visit. Swipe to bookmark from history. Grouped by day, always one tap from opening again.

Setup

Connect your AI key in 10 seconds.

Paste your OpenRouter key below on iPhone or Mac Safari. iOS will offer to save it to your Passwords app, tagged to this site — and once it's there, Fern Browser on your watch can AutoFill it without you ever typing again.

This form runs entirely in your browser. Nothing is uploaded — the key you paste only triggers iOS Safari's "Save Password" prompt for this domain. We never see it.

Privacy

Your data doesn't go anywhere it shouldn't.

Built so that you can use AI on your wrist without trading away your information. Nothing on a server we don't control — because there is no server we control.

  • Your keys never leave the watch. Stored in Apple Keychain, locked to your device.
  • No analytics. No tracking. No advertising SDKs. None.
  • Chats go straight to OpenRouter. Fern has no server in the middle.
  • History stays local. Bookmarks and search history are saved only on your wrist.
