Nemotron ASR

What is Nemotron ASR?

Nemotron ASR is a free online speech-to-text tool for turning audio into clean, readable text in seconds. You can upload common audio files or record straight from your microphone, and it works in 40 languages without needing to pick one first. It adds punctuation and capitalization automatically, so the result is ready to copy or download as plain text. The tool is built around NVIDIA’s Nemotron 3.5 ASR model and is made for lectures, interviews, meetings, voice notes, and field recordings. Free users get three transcriptions per day, and Pro removes that daily limit with more monthly audio minutes. It is simple to use, browser-based, and does not require an account.
