You apply once. Your twin does the rest.

ApplyTwin is a free app for your computer. It finds internships that fit you, writes a one-page resume for each posting and fills out the application. It runs on the Claude Code or Codex plan you already pay for.

Install on Mac or Linux: curl -fsSL apply.twinly.tech/install | bash. On Windows: irm https://apply.twinly.tech/install.ps1 | iex.

Everything between you and Submit.

It finds roles that fit your resume, graduation date and work authorization; writes an honest, tailored one-page resume for each; fills the application on Greenhouse, Lever, Ashby, Workday, iCIMS and more; and stops on the review screen so you press Submit.

No API key. No new subscription.

ApplyTwin runs on your own Claude Code or Codex subscription. It is free and open source: github.com/OjasMishra32/applytwin.

Questions.

Do I need an API key?

No. ApplyTwin runs on the Claude Code or Codex subscription you already have. If you can use either one in a terminal, you can use ApplyTwin.

Where does my data live?

On your computer, in a folder called ~/.applytwin. Signing in backs up your setup so a new laptop picks up where you left off.

Will it submit applications without me?

Only if you turn that on. Otherwise it fills every form and stops on the review screen, so you press Submit.

What will it never do?

Solve CAPTCHAs, accept legal agreements, or change your numbers, titles or employers. Those come to you instead. It signs in and creates job site accounts only if you turn that on, and even then the AI never sees your password: ApplyTwin types it into the page itself.

Does it work on Windows?

Yes. Mac, Windows and Linux. On Windows, paste the PowerShell command.

Is it only for software jobs?

No. It knows what a strong resume looks like in your field, from nursing and finance to design, research and engineering.

Does it work outside the US?

Yes. Pick countries like the UK, Germany, the Netherlands or India and it finds internships, placement years, Werkstudent roles and graduate schemes there, skips postings that need a work permit you don't have, and makes an A4 CV for those jobs.

Why do I sign in with Google?

So your setup, answers and applications are saved to your account. ApplyTwin never posts, emails or signs up for anything as you.

Does it track me?

It counts installs with a random ID, your OS and its version, once a day. Never your resume, jobs or applications. You can turn it off in Settings.

What do I need before I install?

Python 3.9 or newer, Node.js, and Claude Code or Codex signed in on your computer. The installer checks for each one and tells you what is missing.

What does it cost?

Nothing. ApplyTwin is free.
