| Description | Symbolab is an online AI-powered math solver and calculator that breaks problems down step-by-step rather than just returning a final answer, covering algebra, calculus, trigonometry, geometry, matrices, word problems, and graphing. It's built primarily for students and self-learners who want to understand the reasoning behind each step, and it adds practice exercises, worksheets, cheat sheets, and a progress dashboard to reinforce learning. Its main differentiator is the emphasis on explained, worked solutions and personalized practice over a plain calculator's raw computation. | SayHi is an AI-powered Chrome extension that generates personalized, persuasive LinkedIn messages by drawing on a recipient's public profile, letting users set a one-line template and pick a tone of voice. Built by the startup BitBird, it's aimed at recruiters, salespeople, founders raising funds, and professionals growing their networks who want to send tailored outreach at scale rather than generic templates. Its differentiator is that it works directly inside LinkedIn as a browser extension and can connect to CRMs and ATSs to fit existing outreach workflows. |
