Wispr

Wispr was founded in 2021 with the goal of building a non-invasive wearable device that would allow users to control smartphones without touch input.^[1] The device was intended to translate neurological signals into actions and to enable silent text entry by mouthing words, drawing on techniques similar to brain–computer interfaces.^[1][2] Early funding was directed toward this hardware-focused effort.^[3]

After around three years of development, Wispr concluded that contemporary AI systems were not sufficient for the requirements of the wearable device.^[1] The company shifted its focus to Flow voice dictation software, the software layer originally built for the wearable, and in 2024 released a macOS application based on this platform.^[2]

Wispr Flow (often referred to as Flow) is a speech-to-text application for macOS, Windows and iOS.^[1][2] It provides real-time dictation and transcription in more than 100 languages and can operate across applications, including email clients, messaging platforms and chatbots.^[1][2][4] In June 2025 Wispr released an iOS version that functions as a third-party keyboard, allowing voice input in any app.^[2]

Wispr Flow is based on automatic speech recognition (ASR) and other AI models.^[5] The system adapts to individual users over time, learning their vocabulary and preferred style with the aim of reducing manual editing.^[1][6][5]

Flow operates through configurable “Flow Sessions”, defined as time windows during which the app has access to the microphone; users can set session timeouts or disable automatic time limits.^[7]

Wispr initially targeted users such as venture capitalists, entrepreneurs and executives who process large volumes of text and often work in private or flexible environments.^[5] The user base later expanded via platforms such as Product Hunt to students, software developers, writers, lawyers and consultants.^[5] Flow has also been adopted by users with conditions such as ADHD, dyslexia, paralysis and carpal tunnel syndrome.^[1][5]

About 40% of users are in the United States, 30% in Europe and the remaining 30% in other regions. More than 30% of users come from non-technical backgrounds.^[3] Flow supports 104 languages, with approximately 40% of dictations in English and 60% in other languages, including Spanish, French, German, Dutch, Hindi and Mandarin.^[3]

Wispr has reported monthly user growth above 50%, a six-month active-user retention rate of about 80%, a payment rate around 19%, and revenue of approximately US$3.8 million between July 2024 and July 2025.^[5][8]

Wispr has announced plans for an Android application and maintains waiting lists for Android, Linux and web versions of Flow.^[2][7] The company is developing shared-context features for teams so that the software can recognize common terminology within organizations and has stated that it aims to evolve Flow into a broader AI assistant for tasks such as messaging, note-taking and reminders.^[2][3] Wispr has also reported working with unnamed AI hardware partners on interaction layers for future devices.^[3]

In 2025 Wispr raised US$30 million in a Series A funding round led by Menlo Ventures, with participation from NEA, 8VC and several individual investors, including Evan Sharp and Henry Ward.^[1] Earlier investors include Neo, MVP Ventures and AIX Ventures.^[1]

In November of that same year, the company raised a US$25 million Series A extension led by Notable Capital, with participation from Flight Fund, bringing its total funding to US$81 million.^[9][10]

Wispr competes with other AI-based dictation and voice-input tools, including Aqua, Talktastic, Superwhisper and Betterdication.^[2]
