Locked to your campus.
KELO isn't an open website. You sign in with your college email and only ever see your own college's professors and courses. No one outside your institution can see in, and your data is never sold or used for advertising.
Read the privacy policyCollege-gated access
Verified by your college email domain. Outsiders can't browse your professors or students.
Answers from the lecture only
Every result is a passage of what was actually taught, with the lecture and an approximate time attached. Nothing is generated, and nothing comes from the open internet.
Professors stay in control
Each professor owns their course memory and can pause student access or delete lectures and courses at any time.
Private by default
Transcription runs on-device. Audio is never uploaded and is deleted once the lecture is saved.

Our vision
Education that feels personal — where every student can learn directly from their own professors' teaching, and where that teaching, with consent, helps build AI that makes learning easier for everyone.
Our mission
Today, KELO turns real lectures into a private course memory students can ask — grounded in what was actually taught, gated to each campus, professor-controlled. Our mission is to grow this into education AI built on real teaching: trained only on lectures that professors and students explicitly opt in to contribute, always privacy-first, never without consent.
- Grounded in real teaching
- Consent-first
- Professor-controlled
- Free for students
Questions, answered
Does the professor have to do anything extra?
Very little. Tap record at the start of class, stop at the end, and pick the course. Transcription runs on their own device, so they keep the tab open for a few minutes while it processes. Everything after that is automatic.
Can KELO make things up?
No. KELO doesn't write answers. It finds the passages of your professor's own recorded words that best match your question and shows them with the lecture they came from. If the course never covered your question, the closest passages won't really fit, so always check the source it cites.
Who can see my college's courses?
Only verified members of your college. Access is gated by your college email domain, and a course is only visible once its professor has switched it on and been verified by your college's admin.
Who owns the recordings?
The professor. They can review every transcript, pause student access to a course, or delete lectures and courses at any time.
What happens to the audio?
It's transcribed on the professor's own device and never uploaded. It's kept in that browser only until the lecture is saved (so a closed tab doesn't lose a class), then deleted. Only the transcript memory is kept.
