About Develop21

AI working for you. Develop21 provides tools for your AI assistant to inform and guide them as they help you manage your career. Our tools help Claude, ChatGPT and other assistants to produce honest job-fit reviews, resumes and cover letters in the employer's language. This extension is the capture button. On any job listing, click once: 1. **Send to Develop21** — the listing is saved to your Develop21 account. 2. Your assistant opens with the review already queued — pick Claude or ChatGPT — and your Develop21 career profile scores the fit honestly, both directions. No copy-paste, no losing tabs. Works on most job boards and company career pages. Requires a free Develop21 account (sign in at https://www.develop21.ai/start) and the Develop21 connector on claude.ai.
