adamale15/TherapyAI ? reverse-engineered prompt

Build me a therapy skills practice app called Vesh AI where users can sign in, pick from a set of patient personas, and practice conversations with them in a chat style experience. The app should save chat sessions and session history so people can come back to previous practice runs later.

I want the patient responses to feel realistic and be powered by AI, and I also want a way to generate practice cases from uploaded content. Include a clean, simple interface that feels calm and professional, with good use of Tailwind styling. If it makes sense, add speech features so users can practice out loud too.

Please wire up authentication, data storage, and the AI parts so the app works end to end. If anything needs current setup details from the docs, look them up online and use the recommended approach.
