Prompt Stacker — ChatGPT, Claude, Gemini & more

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. • Confirms each send, retries once when safe, and pauses with Retry / Skip controls instead of silently advancing after a failure. • Works on ChatGPT, Claude, Gemini 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 and edit queued prompts, with Undo for removals and clearing; 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. ━━ OPEN SOURCE ━━ The full source is public: https://github.com/thegreatLUCY/prompt-stacker
