AssemblyAI

AI API key

Transcribe audio, and run LeMUR questions over transcripts, with AssemblyAI from any Windmill script, flow or app.

Set up in 3 steps

Transcription is asynchronous

Submitting audio returns an id, not a transcript. Poll it until it completes, or pass a webhook so a flow resumes when it is done.

It is billed per hour of audio

Every transcript draws on your balance. A flow that resubmits on failure can spend more than you expect.

Is my key stored on the hub?

Never. It lives only in your own Windmill workspace, encrypted at rest.
