Questions & Answers

As answered by people managing GhostPrompter and LangSmith.

What makes your product unique?

GhostPrompter's answer

GhostPrompter uniquely combines an entirely transparent, "invisible" desktop text overlay with responsive voice-activated scrolling. Unlike traditional teleprompters that require separate hardware or dedicated windows, GhostPrompter sits directly over your active workspace (like Zoom, Teams, OBS, or slide decks), allowing full mouse click-through functionality. It stays completely hidden from your audience during screen shares, video calls, and final recordings.

What's the story behind your product?

GhostPrompter's answer

GhostPrompter was born out of a real-world frustration shared by digital creators and remote professionals: the struggle to deliver natural online presentations without constantly looking away to read a script. Existing software options often blocked essential background desktop controls, required secondary monitors, or were overly complex. GhostPrompter was built to be a simple, distraction-free desktop companion that feels invisible to the audience but gives total confidence to the speaker.

Who are some of the biggest customers of your product?

GhostPrompter's answer

Independent Content Creators & YouTubers Remote Corporate Executives & Managers Online Educators & Course Instructors Digital Marketing & Product Teams Sales Professionals & Virtual Speakers

Which are the primary technologies used for building your product?

GhostPrompter's answer

GhostPrompter is built using a modern desktop application framework utilizing JavaScript and Electron, combined with optimized local speech recognition engines and real-time audio processing APIs to deliver highly accurate, low-latency voice-activated scrolling.

Why should a person choose your product over its competitors?

GhostPrompter's answer

While most competitors rely on restrictive web-app interfaces and expensive, recurring monthly subscription models, GhostPrompter offers a native, lightweight desktop utility for a simple, flat lifetime fee. Additionally, its advanced click-through navigation ensures that you can seamlessly click, scroll, and interact with your presentation slides or background apps right through the semi-transparent script without breaking your workflow or mouse control.

How would you describe the primary audience of your product?

GhostPrompter's answer

The primary audience includes content creators, YouTubers, online educators, remote corporate executives, and public speakers who frequently deliver virtual presentations or record video content. It is built for any professional who needs to present detailed notes or complex scripts flawlessly while maintaining direct, natural eye contact with their camera.
