The Browser pane
The Browser pane puts the web on your canvas — docs, dashboards, the app you’re building — including sites that normally refuse to embed (it fetches through a local engine rather than a bare iframe). Open it with open browser, Ctrl+Shift+B, or go straight somewhere: open browser and go to github.
Navigating
Section titled “Navigating”- Address bar: URL or search terms.
- go to <thing> (command bar) resolves in order: your favorite by that name → a known site → a web search. go to my dashboard opens whatever you starred as “my dashboard”.
- The pane opens prominently on the left half by default; move/resize freely afterward.
- Pages run their own scripts, so sites that build their content in the browser render normally, and links inside a page navigate the pane. (Before v0.1.166 a page like that could appear as a bare header on an empty background in installed builds, and in-page links did nothing.)
Favorites
Section titled “Favorites”Star the current site and give it a name — from then on go to <name> opens it from anywhere, including by voice.
Clip to notes
Section titled “Clip to notes”Select any text on the page and the notebook button in the toolbar lights up. Click it to append the quote — with the page’s link and today’s date — to your workspace’s research/sources.md. It’s the fastest way to gather sources while you read; pair it with research <topic>, which opens a Research Desk (a browser, a seeded brief in the Writer, and a Scout agent) to turn clippings into a brief.
Streaming note
Section titled “Streaming note”Web content can’t be text-redacted — while live, rely on the privacy scene when opening anything sensitive.
Frequently asked questions
Why can this browser show sites that refuse to embed elsewhere?
Mastery HQ fetches pages through its own local engine rather than a plain iframe, so sites that send anti-embedding headers (news sites, GitHub, etc.) still render inside the pane.
Can I open a project or game an agent built?
It opens on its own — when an agent finishes building a web project, Mastery HQ auto-opens it in this pane. You can also open it any time from the Open chip under the reply, from the Files window, or by pasting the file's path (or a file:// link) straight into the address bar. Either way it's served over a local address and loads like a real site, so multi-file projects, games, and pages that load images or sound as they run all work, not just single self-contained files.
