Phi Browser for Windows 0.4.0

Phi Browser for Windows 0.4.0 — protected video with Widevine

Phi for Windows now plays Widevine-protected video, and picks up more of the Mac's tab, split and onboarding work. It stays on Chromium 156.0.8078.52.

Install

1. Download the installer for your PC below:
   • PhiBrowserSetup-0.4.0.14.exe — Windows 10/11, 64-bit Intel/AMD (x86_64)
   • PhiBrowserSetup-0.4.0.14-arm64.exe — Windows 11 on ARM
2. Run it. The installer and app are signed by Phinomenon Inc.

What's new since 0.3.0

• Widevine: Phi downloads the Widevine module by itself, which can take a few minutes after the first launch, and releases now carry Widevine host signatures. A page that asks for it during that time now waits, for up to three minutes, instead of needing a reload; if Play does nothing while it waits, press it again. Playback passes on Google's Widevine test server and on Spotify on x86_64. We haven't tested other services such as Netflix or Disney+ or played on ARM64 yet, so please tell us what you find.
• Split with New Tab: from the app menu or Ctrl+Shift+\; hold Ctrl to pair a tab that is already open.
• Clear All Tabs, with Undo on a toast, and closing tabs by position or by double-click.
• Bookmarks: a Space's bookmarks sit under a collapsible root row, and an open bookmark's tab can be closed from its sidebar row.
• Always Show URL Path now applies to the address field.
• Onboarding: the Mac's refreshed flow, which also works by keyboard and screen reader.
• Sync recovery code: a first device types its recovery code back before pairing, with a clear warning about losing it and a link to Help.
• Sidebar: a wider resize band that keeps its grab point while you drag.

Fixes

• Text no longer breaks in the middle of a word on double-byte Windows systems, in wrapped text and multi-line boxes.
• Onboarding titles use the right typeface and fit in French and Japanese; the consent sentence stays inside its card, and the focused control scrolls into view.
• The sync setup window responds to Tab, Space and Enter.
• Toasts have transparent rounded corners instead of black squares.
• The address field uses the full pill in a narrow window instead of cutting off the URL.
• The feedback sign-in banner fits its message.
• A window closed with the floating omnibox open no longer crashes Phi.
• A Kiosk gets the keyboard when it opens, and keeps its page when moved to a Space with no window open.
• The signed-out sidebar avatar matches the size of its neighbouring icons.

Upgrading

• From 0.2.0 or 0.3.0: Phi updates itself on the stable channel, or run the installer above.
• From 0.1.0: the early-access build follows a separate channel; run the installer above to move to the signed stable channel.

Phi Browser for Windows 0.3.0

Phi Browser for Windows 0.3.0 — now on Chromium 156

Phi for Windows moves to Chromium 156 (156.0.8078.52, up from 154.0.8037.54 in 0.2.0), with the Mac's omnibox, Space color palettes and a pile of fixes.

Install

1. Download the installer for your PC below:
   • PhiBrowserSetup-0.3.0.10.exe — Windows 10/11, 64-bit Intel/AMD (x86_64)
   • PhiBrowserSetup-0.3.0.10-arm64.exe — Windows 11 on ARM
2. Run it. The installer and app are signed by Phinomenon Inc.

What's new since 0.2.0

• Chromium 156: the browser engine moves from Chromium 154 to 156.0.8078.52, with its security and web-platform updates.
• The Mac's omnibox: inline autocompletion, the top suggestion ready on Enter, Ctrl to switch to a tab that is already open, deletable suggestions and history favicons. With Omnibox as the new-tab behavior, new tabs, empty windows and empty Spaces open the floating omnibox.
• Space color palettes: each Space gets the Mac's palette editor (Settings ▸ Spaces ▸ Color), and two- and three-color palettes paint the sidebar as a gradient.
• Sidebar transparency: a 0–100% slider in Settings ▸ Appearance (default 50%). Appearance's Space color opens the palette editor when you have one Space, or links to Spaces settings when you have several.
• Import from another browser: Chrome, Edge, Brave, Arc for Windows or a file, with profile and Arc Space pickers.
• Sidebar profile button and Library (Spaces and Downloads), and the membership card.
• Shortcuts settings: reset, unassign and rebind page commands and menu chords.
• Peek: a Shift-click on a link no longer lets a single-page app navigate the page behind the Peek, and that page's videos pause while the Peek is open.

Fixes

• Popups (window.open), app windows and undocked DevTools open as regular windows again.
• Tabs in the floating sidebar can be dragged and clicked; the keyboard stays on the page after a file picker; Peek and Reader keep their headers when maximized.
• A bare word typed in the address field is searched instead of opened as a site.
• Switching to a new-tab tab no longer flashes the desktop through the page.
• A reload with no window open no longer replaces your last session.
• Crisper, untinted sidebar account picture; page corners follow the sidebar gradient.
• Space wording and sync strings translated in Spanish, French, Japanese, Korean and Chinese.
• Logs are kept by default, so Report an issue includes them.

Upgrading

• From 0.2.0: Phi updates itself on the stable channel, or run the installer above.
• From 0.1.0: the early-access build follows a separate channel; run the installer above to move to the signed stable channel.

Phi Browser for Windows 0.2.0

Phi Browser for Windows 0.2.0 — now code-signed ✅

This is the first code-signed release of Phi Browser for Windows, on the new stable update channel.

Install

1. Download the installer for your PC below:
   • PhiBrowserSetup-0.2.0.5.exe — Windows 10/11, 64-bit Intel/AMD (x86_64)
   • PhiBrowserSetup-0.2.0.5-arm64.exe — Windows 11 on ARM
2. Run it. The installer is signed by Phinomenon Inc., so Windows shows a verified publisher. As a new publisher, SmartScreen may still ask you to confirm for a while — click More info → Run anyway if it does.

Always-latest download links: x86_64 · ARM64

What's new since 0.1.0

• Code-signed installers and app (Azure Artifact Signing) — no more "unknown publisher".
• Plain .exe downloads for x86_64 and ARM64 — no ZIP to unpack.
• Stable update channel: 0.2.0 and later update themselves from signed stable releases.
• The window title follows the active tab, or the Space while a new tab is open.
• Choosing a Search-X row (Enter or click) opens that engine's site instead of starting a keyword search.
• Sync fixes: a device's Default profile pairs only with your account's default profile, and pinned-tab sync no longer publishes a partial change when the sync scope switches mid-round.

Upgrading from 0.1.0

0.1.0 was an early-access build that follows a separate pre-release update channel, so it won't move to 0.2.0 by itself. Download and run the 0.2.0 installer above to switch to the signed stable channel; from then on, updates arrive automatically.

Phi Browser for Windows 0.1.0 — Early Access

Phi comes to Windows 👋

This is the first public build of Phi Browser for Windows — an early-access release. Phi is a Chromium-based browser built as a native Windows app, with an AI agent that works in the page beside you. It's the Windows counterpart to Phi for macOS.

It's solid at the core but still young, so expect some rough edges — and please tell us what you run into.

Install

1. Download PhiBrowserSetup-0.1.0.14-x86_64.zip below (Windows 10/11, 64-bit).
2. Unzip it and run PhiBrowserSetup-0.1.0.14.exe.
3. These early builds aren't code-signed yet, so Windows SmartScreen will warn that the publisher is unverified. Click More info → Run anyway to continue.

What's inside

• Spaces, profiles, split view, and tab groups
• A native Windows sidebar, with Peek, Reader, and Save for Later (Folio)
• Picture-in-picture, URL rules, and keyboard shortcuts
• Incognito spaces
• Sign in to sync across devices — or just use it as a plain, fast browser

Known limitations

• Early access: some features are still landing and may be rough.
• Not code-signed yet: SmartScreen will warn on first launch (see step 3).
• This release is the 64-bit (x86_64) build.
