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.

RansomLeak Security Training logo

RansomLeak Security Training

freemium

RansomLeak is security awareness training that replaces passive video courses with interactive 3D cybersecurity simulations. Employees don't watch someone explain what a phishing email looks like. They receive one in a simulated inbox and decide what to do with it. They pick up a call from someone impersonating IT support. They find a USB drive near the office door. Every simulation branches based on their decisions and shows them what an attacker would have done next. Each scenario is built on documented attack patterns from real corporate breaches. The format works because active decision-making under pressure produces stronger recall than passive content. When someone gets fooled inside a simulation and watches the damage unfold, they remember it. Training covers phishing, spear-phishing, business email compromise, social engineering across phone, chat, and in-person channels, data handling, password security, physical security, and incident reporting. Multiple difficulty levels per topic. Gamification with points, badges, and leaderboards keeps completion rates high across large workforces. Security teams get analytics showing where knowledge gaps exist across the organization. Deploys as SCORM packages (1.2 and 2004) for Cornerstone, Workday, SAP SuccessFactors, Docebo, Moodle, Canvas, Blackboard, and other LMS platforms. Or as a standalone cloud LMS with user management, real-time analytics, campaign scheduling, SSO/MFA, and custom branding. Built by the Kontra Application Security Training team for mid-market and enterprise organizations in finance, healthcare, technology, and government.
