Multi-Claude

Product Introduction

1. Definition: Multi-Claude is a native macOS application launcher and profile manager specifically designed for the official Claude Desktop client from Anthropic. It is a utility software that creates and manages isolated, application-level instances of the Claude app.
2. Core Value Proposition: Multi-Claude exists to eliminate the friction of managing multiple Claude AI accounts on a single Mac. It solves the core problem of constant logging in and out or using multiple browsers by enabling users to run separate, persistent Claude accounts as distinct, fully-fledged macOS applications.

Main Features

1. Independent Profile-Based Applications: Multi-Claude creates a unique, sandboxed data directory and application wrapper for each user profile (e.g., Work, Personal). Each profile is compiled into a genuine .app bundle located in the /Applications folder. This technical approach ensures each instance runs as a separate system process with isolated session cookies, local chat history, and settings.
2. Native macOS Integration: Every created profile is recognized by macOS as an independent application. This results in separate Dock icons, individual entries in Spotlight search, distinct Launchpad tiles, and independent window management. Users can switch between Claude accounts using standard macOS shortcuts like Cmd-Tab, just as they would between Safari and Mail.
3. Seamless Migration & Local-Only Operation: On first launch, Multi-Claude detects an existing Claude Desktop installation and offers a one-click migration to import its history and settings into a new named profile, keeping the original as a backup. All profile data is stored locally on the user's Mac. The app requires no external account creation and transmits no user data to external servers, ensuring privacy by default.

Problems Solved

1. Pain Point: It directly addresses the inefficient workflow of manually logging out of one Claude AI account and into another, or the clutter of maintaining multiple browser profiles or windows for different accounts. This process interrupts workflow, causes users to lose context, and can lead to accidental cross-account usage.
2. Target Audience: The primary user personas are professionals and power users who maintain separate Claude accounts for distinct purposes. This includes developers, researchers, writers, and consultants using a "Work" account (potentially Claude Team/Enterprise) and a "Personal" account, as well as freelancers or students managing multiple client or project-specific accounts.
3. Use Cases: Essential scenarios include needing to reference a conversation from a personal project while working in a work account, conducting research across different organizational contexts simultaneously, or maintaining completely separate chat histories and custom instructions for different roles without risk of contamination.

Unique Advantages

1. Differentiation: Unlike browser-based workarounds (profiles/containers) or manual data directory switching, Multi-Claude provides an official-app-level experience. It is not a hack but a structured launcher that leverages macOS's native application framework. Compared to simply duplicating the .app file, it provides managed profile creation, visual distinction, and a streamlined migration path.
2. Key Innovation: The core innovation is its "thin wrapper" architecture. Instead of modifying the Claude app itself, it instructs the macOS system to launch the genuine Claude application binary with a unique --user-data-dir argument for each profile. This makes it resilient to official Claude updates and ensures full compatibility with all Claude subscription tiers (Pro, Max, Team), as it's simply running the authentic, signed application.

Frequently Asked Questions (FAQ)

1. Is Multi-Claude allowed by Anthropic's terms of service? Yes, Multi-Claude operates within Anthropic's Consumer Terms, which permit users to run multiple legitimate accounts (such as for work and personal use) on a single machine. The tool is designed for users with separate, authentic accounts, not for circumventing usage limits on a single free account.
2. Will Multi-Claude break when the official Claude Desktop app updates? No. Because Multi-Claude functions as a launcher that runs the official Claude binary with specific parameters, Claude updates itself normally within each profile. The wrapper mechanism is independent of Claude's internal code. If a future Claude update fundamentally changes its launch compatibility, the Multi-Claude developers commit to shipping an update.
3. Can I use my Multi-Claude license on multiple Macs? Yes, a single purchase license for Multi-Claude is valid for use on all Mac computers that you personally own and use. It is not machine-locked.
4. Does Multi-Claude support syncing profiles or chat history across multiple Macs? The current version does not support cloud sync. Each profile and its complete chat history are stored locally on the individual Mac. The developers have indicated that cloud sync features may be considered for a future release based on user demand.
5. Is there a Windows version of Multi-Claude available? Not at this time. Multi-Claude is a native macOS application. Windows compatibility is listed as a feature on the product's development roadmap for potential future release.
