Install Plenior

Requirements

• A Mac with macOS 12 Monterey or later, with Apple silicon or an Intel processor.
• Claude Code, installed and signed in with your own account. Plenior works with it as it is: your sign-in stays with Claude Code, and Plenior never sees your credentials.

Download and install

1. Open the download page and choose Apple silicon or Intel. To check which Mac you have, open the Apple menu, choose About This Mac and look at Chip or Processor.
2. Open the downloaded .dmg file and drag Plenior to the Applications folder.
3. Open Plenior from Applications, Launchpad or Spotlight.

The first launch

When Plenior opens, it checks that Claude Code is ready:

• Install Claude Code means Plenior could not find it. Follow How to install, then choose Check again.
• Sign in to Claude Code means it is installed but signed out. Run claude in Terminal, sign in, then choose Check again.

Plenior finds Claude Code the same way your Terminal does, so if claude runs in Terminal, Plenior can run it too. If it still cannot, see Troubleshooting.

When everything is ready, Plenior shows What should we build? and asks you to open a project folder. Continue with your first conversation.

Language

Plenior follows the language of your Mac. On a system in Portuguese it opens in Brazilian Portuguese, and in English otherwise. To change it, change the language in System Settings → General → Language & Region and reopen Plenior.
