| Description | 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. | CastReader is a text-to-speech reader available as browser extensions and mobile and desktop apps. It reads webpages, PDFs, Kindle books and AI chatbot answers aloud with synced highlighting. |
