Best for quick access

The browser version is convenient for trying TinyChatAI, but the desktop client is recommended for regular use.

Browser local data can be cleared by private browsing, site-data cleanup, or browser storage policies.
Chats and settings are tied to the current browser and device unless you export or recreate them.
Desktop clients provide a more stable long-term workspace for frequent AI conversations.
