Sessions Pro for Codex runs several ChatGPT and Codex accounts side by side on your Mac. Each account becomes its own app, like "Codex Work" and "Codex Personal", with its own Dock icon, login, Codex threads, projects, pins and Codex CLI. Start from your current ChatGPT so nothing is lost, switch accounts from the menu bar, and every profile stays up to date when ChatGPT updates. Free 1-hour preview, then $24.99 one-time.
