Career OS is the candidate side of ResReader — an AI suite that tailors your CV to specific jobs, runs realistic mock interviews, and tracks every application from one place.

Is it really free to try?

Yes. Every month you get 1 free mock interview and 1 free CV optimization, no card required. Upgrade to Premium for 50 interviews + unlimited CV optimizations per month.

How does the CV optimization work?

Paste the job description, pick the CV you want to tailor, and the AI returns a keyword-coverage report plus concrete bullet rewrites. Accept the ones you like and export a clean PDF.

Are mock interviews live or async?

They're on-demand — start whenever you want, talk to the AI for as long as you need, and get a scored breakdown the moment you finish.

Will my CV stay private?

Yes. CVs and interview recordings are encrypted and never used to train external AI models. You can delete everything anytime from your account.

What languages are supported?

50+ languages across CVs, interviews, cover letters, and the UI itself — including English, Turkish, German, French, Spanish, Arabic, Japanese, and more.
