Kortex – Next-Gen Tab & Knowledge Manager

About

Kortex, a production-ready, local-first browser extension built to capture a massive user market. The extension is already fully compatible out-of-the-box with Google Chrome, Microsoft Edge, Mozilla Firefox, and all other Chromium-based browsers. 📉 The Competitor Gap & Market PotentialThe tab management market is heavily fragmented, with incumbents boasting massive user bases but suffering from catastrophic structural and UX failures: OneTab: 2,000,000 users (4.4 ⭐️) but suffers from zero visual organization and severe vulnerabilities to catastrophic local storage wipes. Toby: 300,000 users (4.2 ⭐️) but users are fleeing due to a restrictive 60-tab limit, forced cloud accounts, and recent data loss during migrations. Workona: Highly adopted by enterprise users but plagued by extreme UI bloat and proprietary cloud lock-in. Tabisto: Boasts a perfect 5.0 ⭐️ rating, proving the deep demand for fast, keyboard-centric tools, but currently under-monetized with only 301 users. ✨ Core Features & UXVisual Engine & Focus Mode: Users can toggle between a Trello-style board, an infinite 2D spatial mapping canvas to visually connect tabs, or a distraction-free Focus Mode. Productivity Sidebar: A persistent right-side utility center equipped with a Pomodoro timer, world clocks, and a Kanban scratchpad for quick notes. Advanced Browser Integration: Fills a massive gap in competitors by allowing one-click imports of native browser tab groups and providing instant access to globally pinned tabs. Dynamic Customization: Features a robust engine with 25 pre-built themes—including a True Dark Grey mode—plus support for one fully customizable theme. 💳 Built-In Monetization & Modern StackThe app operates on a highly optimized freemium model, fully integrated with Razorpay for global payments, local currencies, and team billing: Micro-Upgrades & Pro Bundles: As a sales-increasing mechanism, users can purchase a-la-carte micro-subscriptions (Cloud Sync, On-Device AI Search, Extended Workspaces, and Team Collaboration) or upgrade to a complete Pro Bundle. Modern Backend: We have completely ditched FastAPI and migrated to a high-throughput Node.js with Fastify backend, handling sub-100ms WebSocket delta syncing for multiplayer collaboration. Local-First SSOT: Relies on IndexedDB as the Single Source of Truth to guarantee zero-latency UI updates and total offline capability without data loss. Note: Included in the sale is the complete frontend/backend repository, SQL schema, Razorpay webhooks, and full IP transfer.
