Tanay Kothari is an Indian-origin entrepreneur and the co-founder and CEO of Wispr AI, a San Francisco-based company building voice-first software. His work today is centered around a simple idea: people should be able to use computers by speaking instead of typing. That vision is now taking shape through Wispr Flow, an AI-powered speech-to-text tool used across macOS, Windows, iOS, and Android.
But his journey did not start in Silicon Valley. It began in New Delhi, where he grew up and studied at Delhi Public School, R.K. Puram. During his school years, Kothari was known for strong academic performance and active participation in technical and leadership activities. He graduated as salutatorian with a 98% score in science and also served as Head Boy. Alongside academics, he showed early interest in computers, aerospace, and building software products.
Even before entering university, he was already experimenting with technology. Between 2011 and 2015, while still in school, he built several mobile and desktop applications. These early projects included voice assistants, safety tools, and education apps. Some of these products gained real traction, reaching tens of thousands of downloads across multiple countries. This early exposure helped him understand how users interact with software and what makes products scale.
After school, Kothari joined Stanford University to study computer science. At Stanford, he focused heavily on artificial intelligence, machine learning, and venture systems. He also worked as a teaching assistant for Stanford’s deep learning course (CS230), alongside well-known AI researcher Andrew Ng. During this time, he became more deeply involved in AI research and real-world applications of machine learning.
Along with academics, he contributed to research at Stanford’s AIMI (Artificial Intelligence in Medicine and Imaging) lab. One of his notable contributions was co-authoring a research paper on detecting pulmonary embolism in CT scans, published in npj Digital Medicine. This showed his early interest in using AI for real-world problem solving, not just software development.
Tanay Kothari’s Journey

Before founding Wispr, Kothari also explored multiple startup ideas. One of his early ventures, Convert.cc, focused on music intelligence and reportedly reached millions of users without marketing. He also worked on Proximity, a social travel app. Later, he co-founded FeatherX, a personalization platform for e-commerce websites. That company was eventually acquired by Cerebra Technologies. After the acquisition, he worked there as Head of Product and later Head of Engineering, where he led teams and scaled systems.
He also interned at Microsoft as a program manager, where he worked on personalization systems for Microsoft News. His work reportedly helped improve user engagement and revenue across a large global user base. These experiences gave him exposure to both large-scale systems and startup environments.
In 2021, Kothari co-founded Wispr AI with his Stanford batchmate Sahaj Garg. The original idea was not software. The company initially tried to build a non-invasive wearable device that could let users control smartphones without touch. The vision was to translate neurological signals and subtle physical movements into digital actions. It was inspired by brain-computer interface research and aimed at creating a future where devices could be controlled silently.
However, after years of experimentation, the team realized that the technology required for such a device was not ready. AI systems and hardware limitations made it difficult to achieve the level of accuracy and reliability needed for everyday use. Instead of continuing in hardware, they made a major shift toward software.
This decision led to the creation of Wispr Flow, the company’s main product today. Flow is an AI-powered speech-to-text application designed to turn spoken language into clear, structured writing. It works across apps and devices, allowing users to dictate emails, documents, messages, and notes using voice.
The software is not just a basic dictation tool. It uses advanced AI models that understand context, correct grammar, and adapt to a user’s writing style over time. This means the more a person uses it, the more it feels personalized. It learns vocabulary, tone, and common phrases, reducing the need for editing.
Wispr Flow became widely used because it solves a simple but real problem: typing slows people down. Many professionals spend hours every day writing emails, reports, or messages. Speaking is faster and more natural, and Wispr turns that advantage into a productivity tool.
One of the key reasons Wispr Flow is trending is the rise of AI productivity tools and voice-first computing. As people adopt more AI in daily workflows, tools that reduce manual effort are gaining attention. Wispr stands out because it does not try to replace entire systems but improves one core action—writing.
Another reason for its popularity is its cross-platform availability. It works on macOS, Windows, iOS, and Android, and integrates into existing workflows instead of forcing users to change behavior. On mobile, it even works as a keyboard replacement or floating voice input tool, making it flexible for different users.
The company has also reported strong early growth, including high user retention and increasing adoption across both technical and non-technical users. It is used by professionals like founders, lawyers, consultants, writers, students, and developers, as well as people with accessibility needs such as dyslexia, ADHD, and mobility challenges.
Wispr Flow currently supports more than 100 languages, which has helped it expand globally. While English remains the dominant language, a large share of usage comes from non-English languages like Hindi, Spanish, French, German, and Mandarin.
Behind this growth is also strong investor support. Wispr has raised significant funding from major venture capital firms, reaching over $80 million in total funding. Investors see voice-based interfaces as a long-term shift in how humans will interact with technology.
Tanay Kothari often describes his vision in simple terms. He believes future generations should not spend most of their time stuck typing on screens. Instead, communication with devices should feel natural, like speaking. His goal is to make voice the default way humans interact with computers.
Looking forward, Wispr is working on expanding beyond dictation. The company is exploring shared context for teams, AI-assisted messaging, note-taking, reminders, and eventually a full voice-based AI assistant. It is also preparing for Android expansion, Linux support, and deeper integration into daily workflows.
