One prompt.
Every AI.

Run the same question across ChatGPT, Claude, Gemini and more — all opened in parallel tabs with one click.

Try:

How it works

  1. Type your prompt above and choose which AIs you want to compare.
  2. Optionally flip on 📐 Side-by-side windows to open each AI as a positioned window in a grid (instead of separate browser tabs).
  3. Click Open in N AIs — each one launches simultaneously.
  4. AIs marked Auto-fill get your prompt pasted into their input automatically — just hit Enter.
  5. AIs marked Paste don't allow URL pre-filling, so we copy your prompt to your clipboard — press ⌘V (Mac) or Ctrl+V (Windows) once in their input.

💡 Tip: If only one window opens, your browser is blocking pop-ups. Click the small pop-up icon in your address bar and choose Always allow pop-ups from allaitoolhub.com. Side-by-side mode also needs a desktop browser (mobile browsers always open as tabs).
