How a phrase becomes practice
Every phrase on this page has a “Practise it with AI” button. Tap it and the Master Prompt Builder opens with the phrase seeded into a practice prompt for ChatGPT, Claude, Gemini, or Perplexity. The phrase moves from page to conversation in one tap.

Vocabulary apps usually want a subscription and a streak. Vaani does not. This page is a static library of phrases that real people use in real situations — at the office, with a customer, at the doctor's, at the school gate, at a government counter, with a friend over coffee.
A phrase a day adds up. The phrase that comes up today comes up again in a few weeks — that is built in. Tap, learn, mark known, move on. Or skim the library, find the situation you are facing tomorrow, and prepare for it tonight.
If a phrase reads wrong for your situation, or if you want one added that you keep needing, write to me at feedback@aryash.health. The library grows from real feedback.
