Description

A voice-powered text editor that lets you select text and speak changes just like naturally talking to a human, reducing time spent waiting for AI responses. Small edits — like changing a specific number — stay quick and simple.

## The idea

Most AI editors make you select text, write a prompt, and wait. Dash explores a more fluid interaction: talk and point while staying in the document.

> “Make this paragraph shorter. Turn these details into a list. Keep the delivery date I just changed.”

**GPT-6 Astra is the editing intelligence.** It interprets the spoken request together with timestamped selections, generates scoped proposals, and reconciles those proposals against the latest document. You can continue typing while the model works.

Built for the **GPT-6 Astra Hackathon SF**: a native, inspectable prototype of human–AI collaboration inside an editor.

### Astra built it. Astra runs it.

**In development:** the entire project was developed with GPT-6 Astra. We use
