Parallel AI

Compare AI assistants side by side in one window. Send one prompt and review responses faster. Parallel AI opens several AI chatbots in one resizable tab and sends your prompt to all of them at once. You read the answers side-by-side instead of bouncing between tabs.

WHAT IT DOES

• A resizable grid of panels in one tab. Each panel is a different AI chat service you're signed into.
• A floating composer at the bottom. Type once, send to every active panel.
• Drag, drop, or paste files. They are forwarded to each provider's native uploader.
• Synchronize scrolling across panels so long answers stay roughly aligned.
• A usage meter that mirrors each provider's own published plan limits side by side, so you can see which limit you are close to.
• A personal prompt library with variables, categories, favorites, search, and import/export.
• Right-click any page and pick "Pre-fill this in Parallel AI" to send the selection or link into a new comparison.
• Temporary or incognito chat on providers that support it.
• 10 interface languages. Light, dark, or auto themes.

HOW IT WORKS Each panel is an iframe loading the real provider's website, using the session you're already signed into. Parallel AI never sees your credentials and never sees the content of the responses outside of those provider iframes. Everything you do stays on your device.

PRIVACY

• No analytics, no telemetry, no remote servers run by us.
• Settings live in chrome.storage. Your prompt library lives in your browser's IndexedDB.
