Qarta: Your go-to AI instructions, in any AI, in a keystroke

Hi Product Hunt 👋

I run a one-person business, and almost all of my writing — terms of service, product copy, replies to customers — now happens with an AI next to me. I often ask the same question to two or three different AIs and compare.

Two things kept slowing me down: retyping the same instructions in every chat, and never finding the answer I knew I'd already got. Which AI was it? Which chat?

So I built Qarta, an all-in-one toolkit for AI chats:

• Save an instruction once, then type "/" and a keyword in any AI's chat box to drop it in

• Works on the six major AI chat sites: ChatGPT, Gemini, Claude, Copilot, Perplexity and Grok

• Every chat is saved in your own browser and searchable — even when you've forgotten which AI you asked

• Export a whole chat, or just the answers, to PDF, Word, HTML or Markdown, with tables, code and math intact

• Your prompts and chats stay in your browser. I can't see them.

Free: all six AIs, 10 prompts, every chat saved (the last 30 days shown and searchable), whole-chat Markdown and text export.

Pro ($10/month or $96/year): your whole history, PDF / Word / HTML export, choosing what goes in, unlimited prompts and folders, {{blanks}} you fill in right before sending, and one question sent to several AIs with the answers side by side.

There's also a free library of 149 work prompts (English and Japanese) if you just want to copy some: repech.com/qarta/prompts/en

I'd love to hear what you'd want it to do next — or what breaks. I'm reading every comment today.
