RiverScript
Transcribe everything you can hear on your computer
Hi,
I'm Lex, an AI developer from Finland.
The idea for RiverScript came from my wife. She is a student. One day she asked me if it would be possible to build an app that lets you record, for example, a three-hour webinar and get a full AI-generated transcript without any extra steps. All in one application – no separate screen recorders, no downloading video or audio files, no switching between browser tabs. The entire workflow in one place.
That's how RiverScript was born.
Record any audio from your screen. Get the text.
Born from real needs. Built by software engineers. No marketers were involved or harmed during the process.
And yes, it works on both Windows and macOS. It doesn't matter whether you're recording audio from a browser, a meeting app, or any other application – RiverScript works everywhere because it captures the system audio directly.
Your audio. Your rules.
RiverScript was built for real people – students, content creators, and professionals like journalists, lawyers, and healthcare workers. That's why it goes far beyond simple transcription to fit your needs.
● works with audio and video files up to 50 GB, including batch uploads
● has a built-in editor and an interactive media player
● translates transcripts into other languages with AI
● generates subtitles with clickable timestamps
● performs speaker diarization
● creates AI-powered summaries
● lets you ask AI anything about your transcript
And yes, it's built with Rust, a fast programming language, and has a modern, intuitive interface.

Capturing system audio directly instead of making people juggle screen recorders and uploads is the detail that stuck with me. It solves the annoying part people usually just accept.
I can imagine someone asking ChatGPT "what's the easiest way to transcribe a webinar I can only play on my computer" and finding RiverScript without knowing the name first. If they land on a page that already feels like students and professionals are genuinely using it they'll trust it a lot faster with long recordings.
I'm curious which group has been pulling you in first so far. Students like your wife or professionals with bigger transcription workloads?
What stood out to me is that you removed the workflow, not just improved the transcription.
People rarely think, "I need a transcript." They think, "I don't want to spend 15 minutes getting this into a tool." Eliminating that friction feels like the bigger product advantage.
Thank you!
I'm curious—since you've been watching people use it, what part of the workflow have users been most relieved to stop doing?
I have a feeling the answer is more valuable than the transcription itself.
