NotchPrompt: Turning the MacBook Notch into an Invisible Teleprompter, 570k Views on Twitter in 3 Days

2026-02-21 | ProductHunt | GitHub | Official Site

This screenshot shows NotchPrompt in action: a dark floating overlay sits tight against the MacBook notch, with white text auto-scrolling directly below the camera. Developers can read their script while coding, keeping their eyes fixed on the lens.

30-Second Quick Judgment

What is it?: A free, open-source macOS teleprompter that "sticks" your script right next to the MacBook notch. While you read, the person on the other side thinks you're looking them in the eye. It's completely invisible during screen sharing.

Is it worth it?: Absolutely. This is one of those "why didn't I think of that?" tools. It hit 578k views on a single tweet in under 3 days, proving the pain point is real. Plus, it's free and open-source, so there's zero cost to try it.

Three Questions: Is This for Me?

Does it apply to me?

• Target Audience: Anyone who frequently does video calls, online demos, video recordings, or remote interviews. Salespeople, trainers, content creators, and non-native speakers.
• Is that me?: If you have at least one Zoom/Teams meeting a week and often find yourself wanting to peek at notes without being caught—you are the target user.
• Use Cases:
  • Online interviews: Use this to keep your script near the camera when you're nervous.
  • Sales Demos: Glance at key pricing and feature points without losing eye contact.
  • Recording YouTube/Social videos: No need to memorize scripts; just read them.
  • English presentations: A teleprompter can be a lifesaver for non-native speakers.

Is it useful?

ROI Judgment: If you do even one online presentation a month, it's worth installing. It's free; if you don't like it, just delete it.

Why it feels great

The "Aha!" Moments:

• Eye Contact Mastery: You’re reading a script, but the audience thinks you’re staring deeply into their souls. The visual illusion is brilliant.
• Screen Sharing Stealth: When sharing your screen, the audience sees nothing. You look confident and professional.
• Zero-Cost Trial: Free and open-source. No psychological barrier to giving it a spin.

Real User Feedback:

"That's actually goated." — @bil0090, 80 likes

"The ultimate online interview tool is here! Someone made an open-source teleprompter for that spot at the top of the screen. Now you can look like you're staring at the camera while reading your script on Zoom." — @_FORAB, 181k views

"Seeing it pop up outside of Reddit has been surreal. Shipping more updates and actively going to iterate on user feedback." — @heysaif_ (Developer)

For Indie Developers

Tech Stack

• Language: Swift (Native macOS app)
• UI Framework: SwiftUI
• Window Management: NSWindow + NSWindow.SharingType (The core of the screen-sharing invisibility)
• Project Structure: Standard .xcodeproj
• Platform: macOS 13+, supports Apple Silicon and Intel

Core Implementation

The technical implementation of NotchPrompt is straightforward but clever:

First, it uses NSWindow to create a transparent window that floats on the top layer, precisely positioned around the MacBook notch. Text auto-scrolls within this window, and users can adjust speed, font size, and dimensions.

Second, the "killer feature"—it utilizes the NSWindow.SharingType API to ensure the window isn't captured during screen recording or sharing. This system-level "invisibility cloak" has been available since macOS 13. Note: The README marks this as "best-effort/app-dependent," meaning it works for most video conferencing apps but isn't 100% guaranteed for every scenario.

Open Source Status

• Fully Open Source: github.com/saif0200/notchprompt
• License: Public repository
• Similar Projects: Textream (MIT license, includes voice sync), NotchPrompter (MIT license, more basic)
• Difficulty to Replicate: Low. A developer familiar with Swift/SwiftUI could build an MVP in 1-2 weeks. The core is just NSWindow positioning + SharingType settings.

Business Model

• Monetization: None. 100% free and open-source personal project.
• 启示 (Insight): Developer Ali Arain clearly isn't using this to make money directly, but rather to build a personal brand (Viral Twitter reach → GitHub stars → Technical influence).

Platform Risk

Apple could easily build a native version of this into macOS. However, giants usually don't bother with such niche utilities. A bigger risk is macOS changing the behavior of NSWindow.SharingType in future versions, which could break the invisibility feature.

For Product Managers

Pain Point Analysis

• Problem Solved: Looking at notes during a video call = looking down = looking unprofessional. Especially during screen sharing, you usually can't even peek at a memo.
• Severity: Medium-high frequency, near-essential. With remote work, people average 5-10 video meetings a week. Every attempt to peek at notes is a moment of anxiety. 578k views on Twitter shows this resonates deeply.

User Persona

• Core Users: Remote workers, sales reps, content creators.
• Surprise Users: Non-native speakers (the 180k views on Chinese Twitter shows massive resonance) and online interviewees.
• Scenarios: Zoom/Teams meetings, online interviews, YouTube/Bilibili recording, online training.

Feature Breakdown

Competitor Comparison

Key Takeaways

1. "Waste to Wealth" Product Thinking: Turning a hardware defect (the notch) into a product advantage is a brilliant move.
2. Viral Strategy: Explode on Reddit first, then cross-platform to Twitter. A visually impactful short demo video is all it takes.
3. Open Source = Trust: Free + Open Source removes all psychological barriers for users. Compared to Notchie’s $29.99, NotchPrompt spreads much faster.

For Tech Bloggers

Founder Story

• Founder: Ali Arain (Twitter: @heysaif_, GitHub: aliarain / saif0200)
• Background: Full-stack developer (Flutter + Laravel), founder of raptr42. Self-described "Polymath dev," "AI-first, solo, and savage." Previously built the HelioStream real-time streaming library.
• Origin: Based on developer replies, he built it quickly after seeing a demand on Reddit. He noted on Twitter that "seeing it pop up outside of Reddit has been surreal," suggesting it was reposted and went viral unexpectedly.

Discussion Angles

• The Interview "Cheating" Debate: Is this "enhanced communication" or "interview unfairness"? This is a great angle for a deep-dive article. Online interviews are essentially open-book exams; NotchPrompt just makes it more elegant.
• Open Source vs. Commercial Survival: NotchPrompt is free/open-source, while Notchie is $29.99. Two different strategies in the same niche. Who wins in the long run?
• The "Second Life" of the MacBook Notch: From a mocked design flaw to a feature utilized by developers (NotchNook, Notchie, NotchPrompt...), the evolution of the notch is a story in itself.

Hype Data

• PH Ranking: 108 votes (Moderate, but PH isn't the main battlefield).
• Twitter Explosion: 578k views, 6,321 likes, 5,686 bookmarks on a single tweet. A classic case of a product with built-in virality—the demo video is inherently high-impact.
• Global Reach: Simultaneous explosions in English, Chinese (180k views), Arabic (30k views), and Japanese show this is a global pain point.

For Early Adopters

Pricing Analysis

Want voice-synced scrolling? Consider Notchie ($29.99) or the free Textream.

Getting Started

• Setup Time: 5 minutes
• Learning Curve: Extremely low
• Steps:
  1. Go to GitHub Releases and download the latest .dmg.
  2. Open the DMG and drag notchprompt.app to Applications.
  3. First-time open will be blocked by macOS (unsigned) → Go to "System Settings → Privacy & Security" and click "Open Anyway."
  4. Once launched, find the icon in the menu bar → Input or import your script → Adjust speed and font → Start.

Gotchas and Gripes

1. macOS Security Blocks: Since it lacks an Apple Developer certificate, you might have to re-allow it in security settings after every update. This can be a hurdle for non-tech users.
2. "Best-effort" Invisibility: The dev notes that NSWindow.SharingType is app-dependent. It works for most, but test it with your specific meeting software before a big presentation.
3. No Voice Sync: You have to control the scroll manually or via hotkeys. If your speaking pace varies, it might get out of sync. Competitors like Notchie and Textream offer this.
4. Notch-only: It doesn't work well on older Macs without a notch or on external monitors.

Security & Privacy

• Data Storage: Completely local; no internet connection.
• Privacy Policy: Open-source code; you can audit every line yourself.

For Investors

Market Analysis

• Teleprompter Software Niche: ~$128.5M in 2024, expected to grow at 19.3% CAGR to $734.1M by 2030.
• Drivers: Normalization of remote work, explosion of video content, and maturity of AI voice recognition.

Competition

• Top Tier: PromptSmart, VODIUM, Speakflow (Professional grade, enterprise focus).
• Mid Tier: Notchie, Moody (macOS notch-specific, individual focus).
• New Entrants: NotchPrompt, Textream (Free, open-source, community-driven).

Timing Analysis

• Why Now: macOS 13 introduced the APIs that make "screen-sharing invisibility" technically feasible. Combined with the peak frequency of video meetings, the timing is perfect.
• Market Readiness: 578k views prove the demand is real and massive. However, the niche might be too small to support a standalone venture-backed company.

Conclusion

In a nutshell: NotchPrompt is the kind of product that makes you say, "Why didn't I think of that?" It turns the most criticized part of the MacBook (the notch) into its most useful feature (an invisible teleprompter). It's free and open-source, and its viral success proves the pain point is real. The only downsides are the lack of voice sync and the minor friction of installing unsigned apps.
