Claude Code Masterclass: Build Your AI Co-Writing System
A 37-minute tutorial showing non-developers how to replace one-off prompts with a persistent, file-based AI co-writing system built inside Claude Code.
December 10th 2025A 15-minute walkthrough of how Claude Code gets eyes: setup, tab groups, permissions, and three real browser automation use cases with an honest speed warning.
Three words on a dark slide — Your Co-Writer Gets Eyes — and the entire value prop is delivered before Alex says a word. The spoken hook lands the payload: Claude Code now has direct browser access, no MCP workarounds, no manual screenshotting. A capability unlock framed as a persona upgrade.

Title card reveal, Claude Code series branding, promise stated.

Direct browser control, no extra MCPs. Before = manual screenshots; After = side-by-side live access.

claude.com/chrome, Add to Chrome, extension in toolbar, Claude panel opens.

Orange highlight = Claude-accessible. Drag tabs in/out. Claude is sandboxed to the group.

VS Code setup, run claude update, launch claude in fresh terminal.

Run /chrome inside Claude Code — Status: Enabled, Extension: Installed, reconnect if needed.

Notifications, microphone (workflow recording dictation), approved sites list with per-site revoke.

Substack analytics (no API), form-filling on Tally, visual page analysis. Limitations: slow, background only.

Prompt structure: tell it to use Chrome extension + drop the link. Claude navigates autonomously. Do not touch the screen.

Opens second terminal, launches second Claude while first runs in background. Parallel multi-agent workflow.

Voice dictation prompt for second session. Analyze landing page, cross-reference writing system context.

Substack notes: what works (numbered lists, social proof) vs what does not. Landing page: missing testimonials, price, urgency.

Background task tool not a speed tool. Good fit: no-API scraping, visual analysis. Plug for Co-Writer Masterclass.
Claude Chrome only accesses tabs in the orange-highlighted group. Drag in to grant, drag out to revoke. Sandboxed per session.
Browser automation is a background delegation tool for no-API tasks. Not suited for real-time or complex multi-step flows.
Four-part prompt pattern that makes Chrome-based Claude tasks reliable.
Three categories where browser-based Claude automation wins because the APIs do not exist.
“Your co-writer now gets eyes and now has direct access to your browser with this Chrome integration.”
“Substack does not have an API. So it is very difficult to track all of your stats. You kinda have to do it manually.”
“Do not touch the screen that it is working on. Claude is basically taking screenshots and navigating that way. So if you move the page, it is gonna get lost.”
“It is a background task tool, not a speed tool.”
“If you have not checked out my Claude Code masterclass for building your AI co writer, check that out as well because every new thing that comes out just builds on top of your co writing system and supercharges it.”
Soft, organic — positioned as additive context not a hard sell. Framed as the system this feature plugs into.
Alex McFarland is building the same audience Joe is — calling it a co-writer system instead of a dictation app — and this video shows exactly how he packages new capability drops into his product narrative.
If you use Claude Code and spend time manually copying data from sites that do not have APIs, this extension turns that into a background task you can hand off.
