**Attach an audio or video file to a chat and the agent receives a transcript of what was said — no manual transcription required.**

Audio files (MP3, WAV, M4A, and others) are automatically transcribed before being sent to the agent. The agent sees the text. Video files are also supported and can be previewed in the right-hand panel.

1. Click the paperclip icon in the composer or drag a file into the chat.
2. The file appears as a tile in the composer.
3. Send the message. The audio is transcribed automatically.

Where: Web and Mac › composer › paperclip attachment.

Good to know: transcription uses the gateway's speech model and is billed as a tool call. Large files may take a moment to process before the agent responds. You can also attach audio directly from a meeting recording tool using a connector.
