Why friends actually use it
Soft UI so long reading sessions stay comfortable — with a real VALSEA realtime pipeline underneath.
Friendly wording, minimal jargon; mentors get the story in one walkthrough.
One button to record — no timeline drag when judges are on a clock.

VI, EN, ID, TH, MS stay aligned — international teammates tap the right control instantly.
From the classroom
“The UI feels cute but the mic-to-text pipeline is real. Our pitch had the whole hall watching quietly.”
“Prof asked about API safety — I toggled dark mode, pointed at middleware, and we moved on. Less nitpicks.”
“I study late so dark mode saves me. Notes next morning are still gentle on my eyes.”
Open live capture and speak a few lines like you’re in lecture — watch the transcript appear instantly.
No credit card — just a mic and decent Wi-Fi.Dev: run npm run dev:rtt when testing RTT.
