Double is an AI-powered career assistant designed to automate and optimize the job search and career development process. It operates as an agent that can provide personalized career advice, write and tailor resumes and cover letters, manage online professional profiles, identify potential referrers, and submit job applications on behalf of the user. The tool aggregates job listings from multiple sources including job boards, applicant tracking systems (ATS), government databases, social platforms, and company career pages, continuously updating its database with labor market signals. Key features include career guidance based on real pay and hiring data, role matching that ranks positions by how well they fit a user’s skills and experience, and an application system that rebuilds each submission specifically for the target role and company. Double also manages a user’s presence on LinkedIn, GitHub, and X (formerly Twitter) by scheduling posts at optimal times, tightening profiles, and providing recruiter-focused viewing analytics. It can search for people within a user’s network who can provide introductions and automatically craft personalized outreach messages. All applications are prepared and must be explicitly approved by the user before submission. Typical use cases involve a user describing their career preferences and goals to Double, which then cross-references that information against market data to produce a realistic assessment and actionable plan. The agent then finds suitable roles, customizes the application materials, and handles repetitive tasks such as filling out forms. Users retain control over final submissions. Double also helps users build their online brand to attract recruiter attention. The platform offers a free tier with core features, while paid plans unlock unlimited applications, advanced resume optimization, and priority access. Data is encrypted in transit and at rest; user information is not shared with employers without consent and can be fully deleted at any time.
