The clearest way to tell these apart is where each one assumes you're starting from. Teal assumes you may not have a strong resume yet and gives you a builder with templates and guided sections to construct one. Career Copilot assumes you already have a resume — even a rough one — and its job is to score it, tell you what to fix, and match it against real roles.
If you're starting from scratch
Building a resume with no existing draft is a genuinely different problem from optimizing one you already have. A dedicated builder with structured templates removes a lot of the blank-page problem for someone in that position.
If you have a resume and want to know if it works
If your resume already exists and the open question is "will this pass an ATS, and which jobs actually fit it," that's the exact problem Career Copilot is built to answer — upload it, get an ATS and quality score, and see it matched against live postings without switching to a separate interview-prep tool afterward.
Using both isn't unusual
Some job seekers reasonably use a builder for the initial draft and a scoring/matching tool for the ongoing optimization — the two aren't mutually exclusive. Career Copilot's free check works on any resume regardless of what built it.
