  • Subjects grouped by status, color and schedule
  • Each class card links straight to its lecture notes
  • Assignments and grades tracked alongside your classes

See, step by step, how to create a subject in Katav with its color, schedule and professor.

What only Katav does

Three features that change your semester

It's not just storing notes. Katav listens to the lecture with you, organizes your readings and tests you before the exam does.

01

Record the lecture and take notes at the same time

You write what you can; Katav records the rest. Afterwards it fills your notes in with what slipped past and flags the passages where what you wrote doesn't match what was said in class.

Recording + transcriptAutomatic fill-inMisunderstanding alert

02

One hub for the whole reading list

Register the required readings for each subject and build reading notes for articles, chapters and books — reference, core argument, quotations and your own commentary, all in one place.

Required readingsReading notesQuotes and references

03

A mock exam built from your own classes

Katav uses the content of your classes and readings to build a practice exam — timed, graded, and with a report of what you need to review before the real thing.

Student stories

What students are saying

Real words from students already using Katav.

“I take a lot of notes. I always have. But until now, my notes were mostly a way to keep me engaged with what was being said — most of the time, I couldn’t even make sense of what I had written afterward. Not only does it keep everything organized, but I can also ask questions based on my own notes and course material. It helped me so much during an intensive course last summer.”

Frequently Asked Questions

Katav uses AI speech-to-text to transcribe audio in real time or after recording. It supports several languages and handles academic vocabulary well. You can also edit the transcription afterwards if anything came out wrong.

Yes. Import PDFs, Word docs, text files, and even photos of handwritten notes. Katav processes them and adds everything to your knowledge base, ready to search and summarize with AI.

Katav analyzes all your notes and finds themes, terms and ideas that come up across subjects. It then links related concepts. For example: it can show how statistical methods from your Math class show up in your Psychology research methods.

Yes. Your notes and recordings are encrypted. We never share your academic content with third parties. You stay in control of your data and can export or delete it whenever you want.

You can record and take notes offline. AI processing (transcription, summaries and concept connections) needs an internet connection, but your content syncs automatically once you're back online.

No. You keep access to all your files and notes even if you downgrade to a cheaper or free plan. The only exception: Katav can delete accounts that have been inactive for more than 4 years. Before that happens we always send an email. You can also export and back up your notes and files to your computer any time.

Yes. Katav imports your OneNote notebooks automatically — notes, audio, and images. Just go to a subject's classes area and click Import → Import from OneNote. And if you ever want to leave, we export everything back to OneNote. You're never locked in with us.

The semester has started. Start with it.
