Aetherium Download

The browser with an AI agent built in

Aetherium is fast, private and made for the way you work now: ask it to read, click and fill pages for you, keep your passwords in a zero-knowledge vault, and pick up your tabs on any computer.

Coming soon

The first public build is on its way.

Everything you need, built right in

No extra installs. Turn on what you want in Settings.

AI agent

Ask in plain words. The agent reads the page, clicks, types and navigates — with Claude, your own Claude Code, or a local Ollama model.

VaultPass passwords

A zero-knowledge vault: everything is encrypted on your computer before it is saved. Unlock with a PIN, fill logins in one click.

Aetherium Sync

History, bookmarks, open tabs and settings follow you to every computer — end-to-end encrypted with a passphrase only you know.

Chrome extensions

Install from the Chrome Web Store, or load your own unpacked extension in developer mode with auto-reload on save.

Split view & sleeping tabs

Two pages side by side, pinned tabs, tab search, and tabs that sleep after 30 minutes so your computer stays quick.

Built for developers

Network log, page audit, responsive preview, screenshots, a dev-server dashboard and “Send to Claude Code” in one panel.

Always up to date

Aetherium checks for a new version once a day and tells you as soon as one is ready — with a Download button and the release notes right there. You can also check any time from Menu › Help › Check for updates.
