Prompt Stacker — ChatGPT, Claude, Gemini & more

About

Prompt Stacker lets you line up a whole stack of prompts and walk away. Each
prompt sends itself the moment the AI finishes the previous reply — no more
sitting there waiting to paste the next one.

It only does what you'd do by hand: type into the box and click Send when the
reply is done. No API keys, no accounts, no background automation.

━━ WHAT IT DOES ━━
• Prompt queue — stack as many prompts as you like; the next sends automatically
  when the current reply finishes.
• Works on ChatGPT, Claude, Gemini, Google AI Mode and DeepSeek — one extension,
  and it auto-detects which AI you're on.
• Chain replies — use {{last_reply}} to feed the AI's previous answer straight
  into the next prompt.
• Fill-in blanks — write {{topic}} and fill it in once when you press Start.
• Delay, pause, resume, stop — full control mid-run.
• Reorder & edit queued prompts; save sequences you reuse as one-click chains.
• Repeat the whole queue N times to generate variations.
• Auto-continue truncated replies; optional auto-pause on usage limits.
• Follows each site's light / dark mode automatically.
• Collapses to a tidy pill with a live queue count.
• Keyboard shortcuts and one-file backup / restore.

━━ PRIVACY ━━
Everything stays in your browser. Prompt Stacker makes zero network requests and
sends none of your data anywhere. It requests a single permission — storage — to
remember your queue, chains and settings locally.
