-# Create Rubric App
+# Lilac
 
-This project is bootstrapped with [`create-rubric-app`](https://github.com/RubricLab/create-rubric-app).
+Live speech translation with one setting and no conversational machinery.
 
-## Getting Started
+Lilac streams microphone audio over WebRTC to OpenAI's dedicated
+`gpt-realtime-translate` endpoint. The translated transcript is the primary UI; the
+source-language transcript sits quietly underneath it.
 
-### 1. Install dependencies
+Ukrainian text uses a specialized path because it is not a native output of the realtime
+translation model. Lilac requests Russian from the realtime session, then converts a small
+rolling draft into Ukrainian with `gpt-5.6-luna`. Draft text may refine while it streams and
+commits at punctuation or after a short pause.
 
-```sh
-npm i
-```
-
-```sh
-bun i
-```
-
-### 2. Set up the DB
+## Run locally
 
-```sh
-npm run db:push
-```
-
-```sh
-bun db:push
-```
-
-### 3. Run the development server
-
-```sh
+```bash
+cp .env.example .env.local
+npm install
 npm run dev
 ```
 
-```sh
-bun dev
-```
-
-Open [localhost:3000](http://localhost:3000) in your browser to see the result.
-
-You can start modifying the UI by editing [src/app/page.tsx](./src/app/(app)/page.tsx). The page auto-updates as you edit the file.
+Add an OpenAI API key to `.env.local`, then open [localhost:3000](http://localhost:3000).
+Microphone access and WebRTC require a secure context outside localhost.
 
-### Deployment
+## Commands
 
-To serve your app to users, simply deploy the Next.js app eg. on [Railway](https://railway.app/new) or [Vercel](https://deploy.new/).
+```bash
+npm run check
+npm run build
+```
 
-To persist data, you'll need a database. Both [Railway](https://docs.railway.app/databases/postgresql) and [Vercel](https://vercel.com/docs/storage/vercel-postgres) provide Postgres DBs.
