Highlights

• The sidebar hides. Press its toggle, then move to the left edge of the window to bring it back over the page.
• Make the new tab yours: keep the sky or choose a picture from your computer, dim it, and show or hide the wordmark, the tracker, your focus and your tasks. One press resets it.
• On a new tab, the window's glass takes on the light of the sky.
• Zephium opens on a new tab. A startup choice you made yourself stays as it was.
• Windows wears Mica Alt, with a frame that follows your theme. Windows 10 uses acrylic.

Browse

• A page that cannot open, or whose tab crashed, says why and offers Retry or Reload, including tabs restored at launch.
• Recently Closed brings a tab back to its own space. Back and Forward list a tab's history, and View Source and Save Page As are in the menu.
• Closing the last tab opens a new one.
• Downloads pause and resume, and risky files ask before they are kept.
• Sites that ask for a username and password through the browser get a sign-in card, and a refused certificate says what is wrong.
• One site panel at the end of the address field: the connection, blocking, permissions, zoom, hidden elements, extensions and clearing this site's data. Site Settings lists every site's permissions.
• Zoom is remembered for each site. Tabs show their sound and mute from the icon, and the tab that is playing has a player in the sidebar.
• A manual HTTP(S) or SOCKS5 proxy.
• Bookmarks appear in the address bar's suggestions, and bookmarks and history export to a file.
• Import from Helium, Dia, Vivaldi, Opera, Opera GX, Comet, Chromium, Floorp, LibreWolf and Waterfox. Chrome bookmarks kept under a signed-in account come across too.
• Essentials belong to each space.

Windows

• Save Image As and Save Link As work again.
• Switching tabs or opening a new tab no longer closes the browser.
• Passwords and forms save and fill, and Chrome's keyboard shortcuts work: F5, F11, F12, Alt with the arrows, and the rest.
• A page that stops responding offers Wait or Reload.
• The launcher no longer freezes the window the first time, an extension's toolbar no longer holds it up, and fullscreen on a maximized window ends cleanly.
• If Zephium cannot start, it says why in plain words and shows where the log is.
• A SmartScreen switch in Settings under Privacy, and a link to Windows' own diagnostic data settings.

macOS

• Pages that open in a new tab after a redirect, like adding another Google account, load instead of staying blank.
• The in-field menus of extensions such as Bitwarden show up on sites.
• The launcher takes typing the moment it opens.
• Printing no longer changes the Mac's page setup, and the window controls line up with the sidebar's header.

Work and Ask Zephium

• A free Groq key that runs into its limit now says so, and what to do, instead of failing without a reason. Qwen 3.8 27B is available on Groq.
• A helper no longer gets stuck when a model sends empty fields along with its request.
• Runs on a model on your own device or network cost nothing.
• What Ask Zephium writes can be selected and copied.

Security and privacy

• Extensions are kept apart by profile: one cannot replace another's, and deleting a profile removes its extensions.
• A saved provider key is only ever sent to the address it was saved for.
• Ask Zephium asks before it searches, and shows the exact query and where it goes. Allowing history no longer shares your open tabs.
• Windows updates are bound to their version and platform, so an older installer can never be offered as a newer one.
• Clear browsing data covers cookies, site data and the cache, and can clear a single site.
• Notes are not overwritten by a quick edit made outside Zephium, and deleting a profile waits for its notes, so deleted notes cannot come back.
• Safari's files are not read until you choose to import.

Highlights

• A new interface throughout, quieter and more precise, with the window's own material behind the sidebar and the window material of your choice.
• The new tab opens onto the sky, by day or by night with your theme, with your time, your focus and the day's tasks along its foot.
• Ask Zephium, an assistant in the sidebar: it reads the page you are on, takes small steps on it when you ask, restyles a site, and hands larger jobs to Work.
• Zephium AI: sign in with an email code and use hosted models with no keys to manage. 250 credits to start; Pro and Max add 2,000 or 10,000 every month.

Work

• Helpers browse live pages in parallel, in plain sight, and finish forms, searches and listings with native, verified steps.
• Results land on the canvas as tables, charts, diagrams, code and plans, and a plan becomes tasks in one press.
• It asks before it guesses, and before it changes anything.
• Hosted models, your own keys from nine providers, or a local model through Ollama or LM Studio, found on your Mac.
• Dictation, with Apple's on-device recognizer or a hosted engine.

Browse

• Spaces, each with its own look, switched with a swipe, from the menu bar or the rail.
• One menu at the foot of the sidebar for your account, your profiles, a private window and your tools.
• Idle tabs are archived from Today, and links from other apps land where they belong.
• Close a tab with a middle-click, and drag tabs where you want them.
• Every string in twelve languages.

Fixes

• An update check or download that stops responding now gives up and tries again later, instead of holding back updates until you restart.
• About 1 MB smaller to download on both macOS and Windows.

Browse

• A native network blocker turns away ads and trackers before a page can load them, using EasyList and EasyPrivacy, with a count for every site.
• Chrome extensions install straight from the Chrome Web Store, including 1Password, Bitwarden, Grammarly, Dark Reader, SponsorBlock and Notion Web Clipper.
• The launcher, on ⌘ ⇧ Space, reaches tabs, tasks, notes, history and downloads from anywhere on your desktop.
• Tasks you write the way you would say them, landing on the right day.
• Notes beside the page, as Markdown files you own, with code that stays code.
• Time & Focus shows where the day went, and keeps distractions shut.
• A welcome that imports what you already have and sets up the essentials.
• Profiles keep each one's site data apart.

Work

• One switch turns the browser into a canvas, where you describe an outcome in your own words.
• The island keeps one line on what the run is doing, and asks before it guesses.
• Helpers work in parallel on live pages, in plain sight.
• Agents read and edit the folders you grant, and ask before they change a thing.
• They write and explain code, and run commands.
• Connect your tools through MCP servers and the command lines you already use, like GitHub and Slack.
• Results stay on the canvas: tables, comparisons and plans, and tasks made from a plan.

Privacy and models

• No telemetry. Zephium collects nothing about how you browse.
• Local first: history, tasks, notes and activity live on your device, and you never need an account to browse.
• Use Zephium's own AI, your own keys for OpenAI, Anthropic or Gemini, or a model that runs locally.

Platforms

• Apple silicon Macs and Windows, about 20 MB to download.
• Built in Rust on the system's own engine, WKWebView on macOS and WebView2 on Windows. Not a fork of Chromium or Firefox.
• Intel Macs, Linux, iOS and Android are on the way.
