Accounts that don’t mix
Each instance of Claude, ChatGPT or another AI app keeps its own login, history and settings.
For AI users
One AI account per project, all within reach.
Personal Claude, work Claude, a client’s ChatGPT. Mezi opens each account in a separate instance, with its own login and history, without signing out of one to enter another.
Work apart from personal
Keep your company account away from your personal chats, and each client in their own space.
Sign-in that comes back to the right place
AI apps often finish signing in through the browser. Mezi sends the link back to the instance you are using.
Preferences for each one
Theme, shortcuts and settings live in each instance. Changing one doesn’t change the others.
Mezi doesn’t give access to extra features: each account keeps the limits and rules of its own service.

Frequently asked questions
Can I use two Claude accounts at the same time?
Yes. Create one instance per account and sign in normally to each one. The free plan opens 1 instance at a time, alongside your normal Claude. With Pro, you can open as many as you want.
What about ChatGPT and other apps?
Mezi works with Windows programs and Microsoft Store apps, like ChatGPT, VS Code and browsers. To check yours, download it for free and create an instance.
Can Mezi see my conversations?
No. Everything stays in the folder you choose, on your own PC, and Mezi doesn’t send your apps’ data to the internet.
Does this get around usage limits?
No. Each account keeps its own limits and rules. Mezi only separates the logins on your PC. Check each service’s terms about using multiple accounts.
