Two Claude accounts, one laptop.

I have separate Claude Pro accounts for work and personal projects. Work code lives under ~/Developer/Work/Acme, and everything else is personal. I wanted the current directory to pick the account automatically.

Updated 7 October 2026 after Anthropic documented multiple-account support.

#The supported mechanism

Anthropic now documents multiple accounts through CLAUDE_CONFIG_DIR. Each directory gets its own claude.ai login, settings, session history, and plugins.

This also works on macOS. Claude Code keys each Keychain entry to its configuration directory, so the profiles do not overwrite each other's login.

#Route by directory

I built routeai to manage the profiles and directory routes. Install the latest release with mise:

mise use -g github:prettyirrelevant/routeai

You can also build the latest source with Cargo:

cargo install --git https://github.com/prettyirrelevant/routeai

Create the profiles, add the work route, and install the transparent claude command:

routeai init --default personal
routeai profile add work
routeai route add work ~/Developer/Work/Acme

routeai init installs the transparent command. If it prints a PATH step, add that line to your shell profile. Then restart your shell and sign each profile in:

routeai login claude --profile personal
routeai login claude --profile work
routeai doctor

After setup, use claude normally. routeai selects the longest matching directory route, sets CLAUDE_CONFIG_DIR, and forwards every argument to the real command.

Run routeai which to inspect the selected profile. A directory such as Acme-archive stays on the personal profile because route matching preserves directory boundaries.
