tata — Multi AI Chat Side by Side Compare Prompt, Split View Sidebar Boards

Send one prompt to official AI chat sites. Compare real answers side by side in workbench, board or sidebar split view. No API keys.

tata is a free Chrome extension for multi AI chat, side by side compare, and split view. Ask once, send the same prompt to official AI chat websites you already signed in to, and read the live answers together. No API keys. No middleman server in the chat path. Looking for a multi model compare tool, a simultaneous chat workbench, or a ChatHub alternative that does not ask for API keys? tata is built for that: one prompt, several official AI chat sites, side-by-side answers. How people ask this: - Is there a Chrome extension to chat with several official AI sites at the same time? - How do I compare AI answers side by side without switching tabs? - What is a ChatHub alternative that does not ask for API keys? - Can I use my existing web login instead of a wrapper account? What you can do: • Compare official AI chat sites side by side in one workbench, window board, or sidebar • Send one prompt from a shared composer to every enabled AI window • Use the workbench to operate several signed-in AI pages side by side in one tab • Use the window board: a slim console plus real narrow AI browser windows • Use the Chrome sidebar to mirror one prompt between the current page and another AI • Attach images or files when the official site accepts them • Queue the next question while answers are still streaming • Keep each window on the model and effort you saved • Open new chats on every enabled AI at once How to start: 1. Install tata and sign in to the official AI websites you already use. 2. Open the workbench, window board, or sidebar from the toolbar or a shortcut. 3. Type one prompt and send it to the enabled AIs. 4. Read the live official pages side by side and keep the answer you prefer. Privacy by architecture: tata is a remote control for tabs you already own. Prompts go into the official chat sites you selected. The extension does not store API keys or website passwords. Minimized product events never include prompts, answers, or page URLs. Full policy: https://windseed.app/privacy#tata tata is not affiliated with the AI websites it can open. Use each site under that provider's own terms.
