Questions
Which AI does this work with?
Any chat AI that takes text: ChatGPT, Claude, Gemini, Mistral, or a local model. The page builds the prompt; you paste it where you already work. Nothing is sent from this page to any AI service.
What exactly does the check change?
US dates (11/05/2026, November 5, 2026), 12-hour times (3:30 PM), money in US style ($1,249.50, €89.00), miles, pounds (lbs), inches, feet and °F. It adds the output-language line and the form of address the market expects (Sie, usted, você, です・ます) if the prompt sets neither, and warns about word limits in Japanese and fields still left to fill.
Does it convert currencies?
No. It keeps your currency and writes it the local way: $1,249.50 becomes 1.249,50 $ in German and US$ 1.249,50 in Brazilian Portuguese. Exchange rates change daily, so the amount itself is yours to decide.
