Async

Async is a tool built for people who find typing a poor substitute for real communication. In Gmail, it lets you reply to emails with voice notes that are automatically transcribed, include timestamp reactions, and even come with AI-generated summaries—so your recipients can read, listen, or skim, whatever works best for them.

In Chrome, Async lets you add voiceovers directly to your work and share it effortlessly. Whether you're recording a walkthrough, explaining a design, or narrating a document, Async makes sharing your thinking feel natural and human—exactly the way communication should be.
