Overview
Probedex is an AI-powered competitor analysis platform designed for SaaS founders, marketers, and growth teams. It aggregates data from seven sources—SimilarWeb, SEMrush, Ahrefs, Google, YouTube, Reddit, and Product Hunt—to provide a comprehensive view of competitor traffic, SEO, ads, and revenue. The platform offers a large database of 121k+ SaaS domains, allowing users to discover high-growth rivals and generate detailed 'Growth Teardown' reports. These reports include traffic trends, keyword analysis, backlink profiles, ad spend estimates, and AI-generated action plans, all analyst-reviewed for accuracy.
TI 84 Calculator Online is a browser-based emulator of the classic TI-84 graphing calculator. It replicates the physical keypad and display, providing students, teachers, and parents with a free, no-install tool for math practice. The emulator supports a wide range of functions, including graphing, tables, matrices, statistics, and calculus, making it a reliable resource for homework checks, classroom demos, and exam prep.
