2xEverywhere - Universal 2x Playback for Any Video

The Problem

Online courses, tutorials, webinars… we watch countless videos every day. Most people know that watching at 1.5-2x speed is more efficient.

But there’s a problem:

• YouTube only supports up to 2x natively
• Udemy uses its own player
• Corporate LMS often lacks speed control options
• Each platform has different UI, different shortcuts

Do we need a separate extension for each platform?

Solution: 2xEverywhere

One shortcut to 2x any video.

YouTube, Vimeo, Udemy, Coursera, company LMS, even plain <video> tags. Detects all video elements on any webpage and applies 2x speed.

Core Value Proposition

While existing Video Speed Controller extensions support up to 16x, 2xEverywhere supports only 2x.

Why is less more?

1. 100% reliability: No wondering “will this work on this page?”
2. Single shortcut: Alt+2 toggles on/off
3. Zero configuration: Install and done, no settings page
4. Ultra-lightweight: Under 1MB, zero impact on page load

Market

Research shows average adult reading speed is 250-300 WPM, while average speaking rate is ~150 WPM. Many viewers report that accelerated viewing keeps their attention longer.

Existing Video Speed Controller has millions of downloads on Chrome Web Store. But most offer complex settings and UI.

Competitive Analysis

Tech Stack

• Browser Extension (Chrome/Firefox)
• Vanilla JavaScript
• MutationObserver for dynamic video detection

Estimated MVP: 2 weeks

Revenue Model

• Free basic version
• Pro ($3.99 one-time): Custom shortcuts, per-site defaults

Risks

• Monetization difficulty: Browser extension market expects free
• Alternative: Open source + sponsorship model may work better

Next Steps

1. Chrome extension prototype (1 week)
2. Beta testers from Reddit r/productivity
3. Product Hunt launch
4. Firefox port

This idea was inspired by YouTube Custom Playback (Product Hunt 2026.01) and transformed using extreme constraint methodology.
