Wispr Flow

Wispr Flow Notetaker is an advanced AI-powered voice dictation and note-taking tool developed by Wispr Flow, a US-based company. Launched commercially in 2023, it targets professionals and teams needing high-accuracy speech-to-text conversion across any application. The tool leverages OpenAI's Whisper model for speech recognition, augmented by proprietary language models to remove filler words, correct grammar, and adjust tone contextually. It works seamlessly across email clients, text editors, and chat apps, making it a versatile productivity tool.

Architecture

Wispr Flow operates via desktop and mobile apps, capturing audio from the microphone and sending it to cloud servers for processing with Whisper. Subsequently, specialized language models enhance the output: removing repetitions, adding punctuation, and adjusting style. The polished text is then returned to the active application instantly. The tool supports over 100 languages, with a strong focus on English. It also offers a "Notetaker" feature that captures and organizes voice notes, syncable with apps like Claude and ChatGPT.

Performance Features

Wispr Flow boasts low latency (under a second under ideal conditions) and learns user-specific terms and proper nouns via a custom dictionary. It provides voice shortcuts for text editing and navigation. Regarding privacy, the company adheres to a strict no-retention policy for audio data after processing, with advanced security options for teams such as SSO and HIPAA compliance.

Integration and Compatibility

The tool is available as a standalone app for macOS, Windows, iOS, and Android, plus a browser extension. No public API is offered, limiting automated integration with other systems. However, it can be used with any application that supports text input.
