Scribble Party

Product Introduction

1. Definition: Scribble Party is a browser-based, local-first whiteboard and video recording studio. Technically, it is a Progressive Web App (PWA) that functions as a client-side application for creating educational and presentation content.
2. Core Value Proposition: It exists to provide a private, instant, and reliable tool for educators, trainers, and content creators to record lessons without the friction of accounts, cloud uploads, or complex software. Its core value is privacy-first lesson recording and offline-first browser-based whiteboard functionality.

Main Features

1. In-Browser Local Processing & Recording: All processing—drawing, camera feed compositing, background removal, and audio/video encoding—occurs locally on the user's device using Web APIs (like Canvas API, WebRTC, and MediaRecorder API). Recordings are saved directly to the device's storage in real-time, preventing data loss from browser crashes.
2. Infinite Canvas with Live Camera Bubble: The tool provides a digital whiteboard with an infinite, zoomable canvas. Users can activate their webcam, which uses a computer vision algorithm (likely leveraging a pre-trained model like BodyPix or MediaPipe Selfie Segmentation) to perform real-time background removal. This creates a "bubble" or portrait of the presenter that can be moved and resized freely on the whiteboard.
3. Offline-First Progressive Web App (PWA): Scribble Party can be installed as a standalone application on desktop and mobile operating systems. Once installed, it caches its assets and core engine, enabling full functionality without an active internet connection, making it a reliable offline teaching tool.

Problems Solved

1. Pain Point: It eliminates concerns over data privacy, account management, and unreliable internet connections associated with cloud-based SaaS lesson recorders and video conferencing whiteboards.
2. Target Audience: Primary personas include Online Tutors, Corporate Trainers, EdTech Content Creators, University Professors creating flipped classroom content, and Product Managers explaining workflows. Secondary users are anyone needing quick, private explainer videos.
3. Use Cases: A math tutor recording a personalized lesson for a student; a software engineer creating a private architecture walkthrough; a teacher preparing a lesson for a classroom with poor internet; a coach providing video feedback directly on a student's submitted work.

Unique Advantages

1. Differentiation: Unlike platforms like Loom, Miro, or Explain Everything, Scribble Party requires no sign-up, stores nothing in a third-party cloud, and has no subscription model. It prioritizes user sovereignty over data. Compared to desktop software like Camtasia, it requires no installation (as a web app) and is instantly accessible.
2. Key Innovation: The integration of client-side background removal with a local-only MediaRecorder pipeline within a standard web browser is its technical innovation. This combination delivers a cloud-like user experience (green-screen effect) while maintaining complete local data control, a rare feat in web applications.
