What does Arnold do?
Arnold is a Chrome extension that acts as your AI co-pilot for LinkedIn. It integrates directly into the platform to help you with virtually every task, from proofreading a message to a hiring manager to generating a thoughtful comment on a post in your feed. It's designed to understand the context of the page you're on and provide relevant, intelligent assistance without you having to copy and paste information back and forth.
What makes Arnold stand out is its deep integration and context-awareness. It automatically extracts information from the LinkedIn page you're viewing—be it a profile, a job posting, your messages, or your feed—and uses that context to generate tailored suggestions. For example, it can summarize a person's profile for you or help you craft a follow-up message based on your previous conversation history. It offers different feature tiers, with a free plan for basic profile and job page assistance and a professional plan for unlimited, full-platform access.
This tool is a major time-saver for anyone who uses LinkedIn seriously. Job seekers benefit from instant cover letter generation and profile optimization tips. Sales professionals and recruiters can craft more personalized outreach at scale. Even casual networkers can use it to maintain an active, engaging presence with smart comment suggestions. If you want to be more effective on LinkedIn without spending hours crafting every single interaction, Arnold is built for you.
