aicx

aicx

Switch between Codex and Claude Code accounts without losing local conversation history.

aicx keeps credentials and settings separate for every account. Saved conversations are shared by default, so you can start with one account and continue with another.

Install

You need Linux or macOS, Python 3.9 or newer, and the official Codex or Claude Code CLI.

pip install aicx
aicx doctor

Set up two accounts

Codex example

aicx login codex personal
aicx login codex work

Each command launches the official Codex login inside that profile's private CODEX_HOME, so every profile receives an independently issued OAuth session. Standard browser OAuth is the default. Device-code login is optional and is mainly useful on headless or remote machines:

aicx login codex personal --device-auth

If you already have Codex settings and conversations under ~/.codex, import the safe local state with:

aicx adopt codex personal

For Codex, adopt intentionally excludes CLI and MCP OAuth credential files, fixes profile-local configuration and session paths, then starts a fresh browser login for the new profile. It does not change the source directory. Codex OAuth credentials are never copied between profiles.

Claude Code example

# First account
claude auth login
aicx adopt claude personal
claude auth logout

# Second account
claude auth login
aicx adopt claude work

Profile names are yours to choose. personal, work, and client are only examples.

Use an account

Launch the provider with @account-name:

aicx codex @personal
aicx codex @work
aicx claude @personal

The last selection is remembered:

aicx codex
aicx claude

Provider arguments pass through normally:

aicx codex @work resume --last
aicx claude @personal --resume SESSION_ID

Rename or delete a profile

aicx rename claude test1 personal   # move one tool's profile to a new name
aicx forget claude personal         # delete one tool's profile (asks first; --yes skips)

Both act on a single tool. forget keeps the shared conversation history and leaves the other tool in that profile untouched. Neither works while a tracked process for that profile is still running.

Accounts and usage

aicx accounts
aicx balance
aicx balance codex --profile work

Keep the balance view open and refresh it every 60 seconds:

aicx balance --watch

Choose another interval when needed:

aicx balance --watch --interval 15

The balance table shows usage, remaining percentage, reset time, and the time left until reset.

Pick the columns you care about; the choice is saved and reused on the next run:

aicx balance --columns tool,profile,window,usage,reset-in
aicx balance                       # same columns as last time
aicx balance --reset-columns       # forget the choice, show every column

Column names: tool, profile, active, account, window, usage, left, reset-in, reset, source.

Conversation history

aicx synchronizes saved history before a provider starts and after it exits. This lets you exit a conversation and resume it with another account.

Do not open the same conversation from two accounts at the same time. History sharing supports sequential handoff, not concurrent editing.

# Manual synchronization
aicx sync codex
aicx sync claude

# Optional: disable sharing
export AICX_CODEX_HISTORY=isolated
export AICX_CLAUDE_HISTORY=isolated

Credentials remain private to each account profile. They are never shared with the conversation store.

Codex OAuth troubleshooting

If Codex or codex_apps fails with HTTP 401, token_revoked, or Encountered invalidated oauth token, older aicx versions may have copied one rotating OAuth refresh token into more than one profile.

aicx doctor
aicx accounts codex
aicx login codex personal --force
aicx login codex work --force

Run the forced login once for each affected profile. The safe forced-login flow removes only that profile's local Codex CLI credential before starting a fresh login. It preserves settings, sessions, history, MCP credentials, and the profile name, and it does not run codex logout or revoke a token that an older cloned profile may still hold.

Do not use codex logout to migrate profiles that may contain cloned OAuth credentials. aicx doctor compares one-way refresh-token fingerprints and never prints credential values.

TODO

• Test the complete workflow with multiple real Claude Code accounts. Multiple Codex accounts are tested.
• Add and test VS Code account integration.
• On macOS, confirm profile-local Claude credentials when the login Keychain holds a Claude Code-credentials item (Codex is pinned to file storage).
