ego is a personal AI agent that lives across your browser, desktop, and phone. It remembers your projects, preferences, and work patterns, and runs multiple tasks in parallel 24/7. You can interact with ego via voice (just hold fn and speak), iMessage, Dynamic Island, a desktop agent, or its AI browser. Hand it tasks like summarizing tabs, replying to emails, conducting deep research, building apps from descriptions, generating content in your tone, filling forms, or monitoring web changes. ego works while you're away, delivering finished files and pinging you for approvals. Unlike chatbots, ego doesn't just chat—it acts inside your real accounts and files, learning from your actual work activities. It builds persistent memory so it gets better at knowing you over time. Unlike AI browsers, ego runs tasks in the background 24/7, across devices, and handles entire workflows beyond the browser. Your data is encrypted, synced across devices, and never used for training AI models. ego is made for everyone, not just developers, and requires zero configuration.

Applyre AI logo

Applyre AI

paid

Applyre AI automates the most time-consuming parts of job hunting. Instead of searching and applying manually, the platform scans thousands of company career pages every day, finds roles posted within the last 24 hours, and filters them by your exact preferences—like location, remote, salary, and skills. It even skips companies you’ve blocked, so only relevant opportunities reach you. Once jobs are identified, Applyre’s AI fills out the application form with your profile, customises your resume to the job description, and generates a tailored cover letter that reads like you wrote it yourself. Every application is then reviewed by a real person who checks accuracy, tone, formatting, and overall fit before submission. The application is submitted directly through the company’s career page—just as you would do manually—and you receive the confirmation email in your own inbox. With plans starting at 40 applications per month, Applyre helps you reclaim over 25 hours each week and get significantly more interviews by getting your application in front of hiring managers early, beating both applicant tracking systems and the competition.
