Why it's different
From spoken thoughts to finished text.
On Mac, Fluid Speech Mini handles transcription. Fluid Intelligence then cleans up your words with a Fluid-1 model — all locally, by default.
01
You speak
Hold one hotkey and talk normally — ums, stumbles, and mid-sentence changes of mind included.
02
Transcribed on-device
Fluid Speech Mini converts your audio to text on your device.
03 · Fluid-1
Fluid-1 rewrites it
Our custom-trained post-processing model strips filler, fixes casing, formats structure, and matches the tone of the app you're in.
