Lemonsignal is an AI skills assessment for hiring. Candidates do a real work task in the AI tool they already use (Claude Code, Codex, Claude Cowork or ChatGPT), on their own computer or in the browser, in the time you set. Lemonsignal reads their whole conversation with the AI, and someone who has done the job scores six skills: Understand, Brief, Check, Correct, Sign off and Reuse. Every score links to the moment in the conversation it came from. It works for any role: engineering, product, design, marketing, data and finance, plus AI basics for everyone else. AI is the fastest, most confident junior colleague most people have ever had. Lemonsignal tests how well people manage it. Try it free on 3 candidates. Packages from $15 per candidate, or monthly plans from $399.
