Unified extension menu and capture widget

Core actions are now grouped into a cleaner, more guided experience.

• Faster access to key capture modes: Start with Story Capture, Continuous Capture, or Capture Single Screen directly from the main widget.
• Expanded advanced capture options: Open More capture methods to access additional workflows, including Video Capture.

Why this matters

The updated extension reduces the number of steps between “I want to capture this” and “this is ready to build with,” while still preserving access to advanced capture workflows when you need them.

Quick Start Guide

Follow these steps to install, launch, and start capturing with the updated Walnut Chrome Extension.

Before You Start Capturing

Review our Capture Best Practices to help prevent sizing or layout issues and ensure cleaner capture results.

1. Install or update the extension from the Chrome Web Store.

2. Pin the extension to your browser toolbar for easier access.

3. Open the extension to launch the redesigned capture widget.

4. Keep the debugger banner active when your browser refreshes. This banner is expected and should remain visible during your capture session.

5. Choose your mode using the toggle at the top of the extension: Capture Screens for Admins and Editors, or Play Demos for Presenters.

6. Choose a template destination by selecting either New Template or Existing Template.

7. Set your screen size using the integrated screen resizer. You can keep the current browser size or choose a preset such as Desktop, Laptop, or Mobile.

8. Select your capture mode based on how you want to build.

• Record Demo Story via Story Capture or Continuous Capture
• Capture Single Screen
• More capture methods for advanced workflows including Video Capture

Quick Tip

Use the main extension widget for your most common capture workflows, then open More capture methods when you need more advanced options or specialized capture modes.

Preset Sizes & Best Practices

The integrated screen resizer in the Walnut Chrome Extension allows you to quickly standardize your capture environment using preset screen sizes. Choosing the right preset before capturing is one of the most important steps for ensuring a clean, consistent, and scalable demo build.

Available Preset Sizes

You can select from the following preset options directly within the extension:

• Desktop (1920 × 830): Best for full-width product experiences and larger UI layouts where maximum screen real estate matters.
• Laptop (1440 × 721): Recommended default for most demos. Balances quality, editability, and the most common viewer experience.
• Mobile (500 × 787): Ideal for capturing true mobile or responsive experiences designed for smaller screens.
• Desktop on Mobile (1440 × 720): Captures a full desktop viewport while optimizing for smaller or split-screen presentation. This is the best option when you want a desktop experience to scale cleanly on mobile devices, embeds, or side-by-side layouts without breaking responsiveness.
• Previous Captures: Matches the screen size of the last captured screen in your existing template to keep all new captures aligned and consistent.

Recommended Default

Laptop or desktop presets provide the best balance between quality, editability, and consistency across most demo use cases.

Best Practices for Capture Sizing

Use Laptop or Desktop presets for most workflows

It reflects the most common user environment and keeps demos easier to build and maintain. Ensure the entire building team is aligned on the same preset to maintain consistency across all captures.

• Start with one consistent size: Capture your entire flow using a single preset to avoid scaling issues and visual inconsistencies.
• Set zoom to 100%: Browser zoom and system zoom impact capture quality, consistency, and end resolution. Always reset both settings to 100% before capturing.
• Avoid mixing resolutions: Combining sizes (e.g., 1920×1080 and 1440×721) can make editing harder and break layout continuity.
• Use Mobile intentionally: Only use the mobile preset when the experience is truly mobile-first or responsive.

Why this matters

Consistent sizing directly impacts how polished your demo feels. Standardized captures make editing easier, improve visual flow, and reduce time spent fixing layout issues later.

Capture Modes

The updated extension gives you access to multiple capture workflows depending on how you want to build your demo.

Important: Story Capture requires AI terms to be approved in Company Settings. If AI is not enabled, this option defaults to Continuous Capture.

Capture Mode	Description
Story Capture	Capture a workflow while narrating and let GenAI generate guided demo steps automatically.
Continuous Capture	Capture multiple screens in sequence as you click through your workflow.
Capture Single Screen	Capture one screen at a time.
Video Capture	Record a workflow directly from the browser tab and automatically add it to your template as a video screen. Learn more.
More capture methods	Opens the advanced capture widget with additional methods such as Timed Capture, Update Screen, and other specialized capture workflows.

Note

The main extension widget surfaces the most commonly used capture actions first. Advanced or specialized options remain available through More capture methods.
