Blurt

Blurt at a glance
Blurt is a free, open-source Mac dictation app from AssemblyAI. It is designed for entering spoken words into the text field where you are working: hold a key, talk, and the words are placed wherever you are typing.
The app runs on AssemblyAI's Dictation API, which turns a spoken clip into finished, formatted text in one request. The source demonstrates a workflow for replacing some keyboard entry with short voice input, while leaving platform requirements, account setup, privacy behavior, and detailed Blurt controls unspecified.
Features
Text-field output
Blurt inserts the resulting words into the text field where you are already typing, rather than requiring a separate transcription window.
Finished dictation text
The app is powered by AssemblyAI's Dictation API, which returns finished text instead of only a raw, verbatim transcript.
Fast response through the Dictation API
The underlying API is built for short spoken clips and reports typical short-clip responses in under a second, with a p50 of 134 ms; the product pages do not state a separate Blurt latency.
Multilingual and configurable API foundation
The Dictation API supports 19 languages, automatic language detection, native code-switching, key-term prompting, and formatting instructions. The available materials do not establish which options are configurable in Blurt itself.
Open-source Mac app
Blurt is released as free, open-source software, with the download page linking to its GitHub repository and identifying an MIT license.
Use cases
Writing in text fields
Speak a sentence or paragraph while composing an email, document, or message, then continue working with the text in the active field.
Voice-entered prompts
Use short spoken prompts when typing into an AI assistant or other text-based tool is slower than saying the request aloud.
Quick note capture
Capture notes while moving between tasks by dictating directly into the application or document where the note belongs.
Alternative to keyboard entry
Use the API-backed workflow to enter text when keyboard input is inconvenient, such as during hands-busy work; the source does not specify particular supported applications.
