Citedto the exact second of the source
Answers with receipts.
Ask in plain language, and the assistant answers from the source — never from memory. Every claim points to the exact second it was made, so you verify it in one tap.
- Ask naturally: “What was the professor's main argument?”
- Every answer carries citations with the exact start time.
- Tap a citation and jump straight to that moment in the transcript.
- When the evidence isn't there, the assistant says so instead of guessing.
“The lecture's core claim is that memory is reconstructive — each recollection rewrites the one before it.”
at 12:41 — “What was the main thesis of the lecture?”

Briefs that version like code.
Generate a brief from a class, then regenerate it as the material evolves. Every version is kept — compare, revert, and never lose the chain of thought.
4stages: Source → Transcript → Knowledge → Brief
Class to knowledge in four stages.
One pipeline turns a raw class into something you can ask. Each stage builds on the one before it, and every stage keeps its evidence.
- Source — the recording is stored immutably.
- Transcript — every second is timestamped.
- Knowledge — the material becomes citable units.
- Brief — a versioned summary you can regenerate.
Ask yesterday's class at 2 AM.
The room is dark, the answer is at minute 47, and nobody is awake to ask. Open RuuRuu OS, ask in plain language, and jump straight to the second that settles it.
Questions, answered.
How do I know the answers are true?
Every answer cites the exact second of the source it came from. Open the citation and you land on the moment in the transcript — you verify the claim yourself, in one tap. When the evidence isn't there, the assistant says so instead of guessing.
Who can see my classes?
Only your workspace. Every class, transcript, knowledge unit, and brief is scoped to the workspace with row-level security — nothing leaks across workspaces, and the source is kept immutable once it's uploaded.
Does it work in my language?
Classes are transcribed and analyzed in their source language, and you can ask questions and generate briefs in your preferred output language.
How do I get started?
Upload a class, get the timestamped transcript, ask a cited question, generate a brief. The dashboard lists every class with its processing status, so you always know where each one stands.
What's said stays said.
Your source is fixed the moment it's uploaded — immutable and audited. Everything built on it — transcript, knowledge, briefs, answers — carries the evidence back to that original second.
