Your computer already listens. Now it understands.
Understand any audio your computer can play. Read it, search it, translate it, hand it to an AI. It all happens on your machine — nothing leaves it.
The demonstration
Pick a source. Watch it become text.
Kupas captures whatever is playing and resolves it in real time. Switch the source below — the panel updates as it would while the audio runs.

The gap
Text became something you can work with. Sound never caught up.
A document, an email, a page — you can search them, summarize them, translate them, ask questions about them. Audio still mostly just plays. You hear it once and it's gone.
Written
Search a word. Jump to a line. Translate a paragraph. Quote it. Ask an AI about it.
Spoken
Play it again. Scrub back. Hope you catch it this time. Then lose it.
heard once — not kept
Kupas closes the gap. Any audio becomes a resource you can work with the same way you work with a document — whatever app it came from, whatever language it's in.
The transformation
Where audio becomes text becomes anything.
Transcription is the doorway, not the destination. Every sound moves through the same path — and ends as something you can actually use.
Audio
Whatever is playing
System sound from any app — a stream, a call, a file, a video.
Text
Resolved on your machine
Sound becomes clean, searchable text as it plays.
AI
Your templates
Run it through custom prompts — translate, summarize, extract, rewrite.
Result
Something you can use
Summary · EN
Runs locally. Nothing sent to the cloud. Readable, searchable, yours.
A translation, a summary, a quote, a saved recording you can return to.
Local by design
And all of this stays with you.
The audio, the text, the processing — everything runs on your machine. Your material never has to leave it to become useful.
The usual path
Your audio takes a trip to someone else's servers before it comes back as text.
With Kupas
One path. It starts and ends on your computer. No account required to understand your own audio.
Where it fits
One capability. Many reasons to want it.
Kupas doesn't care what you do. It works on any audio your computer plays — so the reason to reach for it is yours.
Creators
Capture a co-stream, an interview, a reference clip. Turn it into text you can clip, quote, and repurpose without scrubbing back through hours of audio.
Everyday listening
That idea you heard in a podcast last week? Find it by searching a word instead of replaying the whole thing.
Learning
Follow a lecture or a talk in another language. Read along, translate a passage, keep a version you can review later.
Accessibility
Read what the audio is saying — from any app, whether or not it ships captions of its own.
Inside Kupas
Built to sit with you over time.
Not a one-shot tool. A quiet layer that captures, processes, and keeps — however you want to work with what you hear.
