Dinamo Notebook

Product Introduction

1. Definition: Dinamo Notebook is an open-source, browser extension for football video analysis and tactical drawing. It operates as a local-first software tool, specifically a Chrome/Edge extension, designed to transform standard web browsers into professional-grade sports analysis platforms.
2. Core Value Proposition: It exists to provide a free, transparent, and privacy-centric alternative to expensive, cloud-dependent football analysis software. Its core promise is to deliver professional-grade tactical analysis, drawing, and note-taking tools that run entirely on the user's machine, ensuring complete data ownership and eliminating subscriptions or vendor lock-in.

Main Features

1. Integrated Video Analysis Platform: Dinamo Notebook functions as a browser extension that automatically activates on supported video platforms. It analyzes match footage directly from YouTube, Dailymotion, Twitch (live and VOD), or local files without requiring downloads or re-uploads. The core technology involves injecting a sidebar and overlay interface into the active browser tab to interact with the HTML5 video player, enabling frame-by-frame navigation, timestamped note-taking, and synchronized drawing.
2. Professional Tactical Drawing & Visualization: The extension provides a dedicated toolkit for creating professional tactical diagrams directly on paused video frames. It includes standard football pitch templates, a suite of drawing tools (arrows, shapes, highlights, tactical symbols), color-coding for teams and zones, and a multi-layer system. This allows users to build complex, multi-slide sequences for breaking down phases of play, player positioning, and team formations, suitable for coaching presentations and match reports.
3. Local-First Data Management & Export: All project data, notes, and drawings are stored locally in the browser using its storage API. The system is project-based, enabling organized analysis of matches, teams, and sessions. It features full database export/import (JSON), version history, and powerful search/filter capabilities. Export functions allow users to generate polished PDF reports, high-resolution images (PNG/JPEG), animated GIFs of tactical sequences, and portable project backups, turning local analysis into shareable content.
4. Optional AI-Assisted Tactical Analysis: Users can optionally integrate their own OpenAI API key to enable AI-powered analysis features. The AI acts as a targeted assistant, answering specific tactical questions about formations, defensive patterns, pressing structures, and coaching alternatives. The system is designed for user-directed inquiry, with API requests made directly from the user's browser to OpenAI, ensuring no intermediate data processing or storage by the developers.
5. Multi-Language Support & Open Architecture: Built for a global audience, the interface supports English, German, Spanish, French, Portuguese, and Serbian. As an open-source project (MIT licensed), its code is publicly auditable and modifiable, fostering community contributions in areas like code, features, testing, and translations. This transparency is a core technical and philosophical feature.

Problems Solved

1. Pain Point: High cost and platform lock-in of commercial football analysis software. Dinamo Notebook solves the "expensive subscription" and "cloud-locked data" problems by being 100% free, with no paid tiers, and storing all data locally on the user's device.
2. Target Audience: The primary users are football analysts, coaches, developers, and dedicated fans. It specifically serves tactical analysts who need professional drawing tools, coaches preparing training materials, developers interested in open-source sports tech, and fans who deeply analyze the game and want transparent, hackable tools.
3. Use Cases: Essential for post-match tactical breakdowns using YouTube or Twitch recordings, creating annotated coaching videos for player education, developing multi-slide analysis presentations for team meetings, building a personal library of analyzed match projects, and generating shareable tactical GIFs for social media or reporting.

Unique Advantages

1. Differentiation: Unlike cloud-based SaaS platforms (e.g., Hudl, Sportscode), Dinamo Notebook is free, local-first, and open-source. Unlike simple screen recorders or basic drawing tools, it offers an integrated, football-specific analysis environment with structured data management. Its browser extension model also allows analysis to happen "where the video lives," eliminating file management steps.
2. Key Innovation: The key innovation is the synthesis of a browser-native, local-first architecture with a professional, specialized feature set for football analysis. By running entirely as a client-side extension and utilizing the browser as its runtime, it achieves a unique combination of accessibility (no installation beyond the extension), privacy (zero telemetry), and powerful functionality traditionally only found in installed desktop applications.

Frequently Asked Questions (FAQ)

1. Is Dinamo Notebook free, and are there any hidden costs? Dinamo Notebook is 100% free with no subscriptions or paid tiers. The only potential cost is for the optional AI features, which require your own OpenAI API key and are subject to OpenAI's standard usage pricing. The extension itself has no cost.
2. How does Dinamo Notebook handle my privacy and data? It follows a strict local-first and zero-collection policy. No accounts, tracking, or analytics are used. All analysis data is stored solely in your browser's local storage. AI requests go directly from your browser to OpenAI; no data is intercepted or stored by the developers.
3. Can I use Dinamo Notebook on Firefox or other browsers? Currently, the stable release is available for Chrome and Microsoft Edge. The README notes that a Firefox version is planned but not yet released. It is a standard browser extension, so future compatibility may expand.
4. What kind of AI assistance is provided, and do I need it? The AI is entirely optional and requires your own OpenAI API key. It serves as an on-demand tactical assistant, answering specific questions you pose about formations, player movements, or defensive strategies. It is not a required component for the core drawing and analysis features.
5. What can I export from my projects, and how do I share analysis? You can export comprehensive PDF reports, high-resolution images of any frame with annotations, animated GIFs of tactical sequences, and raw data in JSON/CSV formats. A built-in presentation mode also allows for live sharing of analysis directly from the extension.
