A real notebook for your real semester — with AI that supports what you wrote.
StudyFetch is designed around documents you upload — it generates summaries, flashcards, and a tutor on top of them. Katav takes a different angle: you take your own notes in class, and the AI uses the lecture recording to complete what you missed and quietly point out passages that may not match what the professor actually said.
Katav
Your own notes, completed and reviewed by AI
StudyFetch
AI tutor on top of uploaded documents
Four things students switch to Katav for
Both products are useful — they are built for different workflows. Here is where Katav tends to fit students better.
A notebook where you actually write
StudyFetch is designed around files you upload — most of its content is generated from those uploads. Katav puts a real rich-text editor at the center of each class, with formatting, images, and structure. Your notes stay yours; the AI works around them.
AI that completes and reviews your notes
When you record a class, Katav reads what you wrote and listens to the lecture. It can fill the small gaps you left while you were busy listening, add details you missed, and gently flag passages where your notes may not match what the professor actually said — so you can review and decide.
Organized around your courses
Katav assumes your semester is structured into courses, subjects, and individual classes, and organizes everything that way by default. StudyFetch leans on folders and standalone study sets, which you arrange yourself.
A free plan with real lecture hours
Katav's free plan includes 3 hours of lecture transcription per month — and unlimited transcription if you are on iOS 26. StudyFetch's free tier (10 Spark.E chats, 1 study set, 2 uploads) is built around uploaded materials. Which fits better depends on whether your week is mostly live classes or studying from documents.

Bring your study material in three steps
Nothing you have already done is wasted.
1
Bring your PDFs, slides, and materials
Upload everything you were already feeding into Spark.E. Katav indexes each file under the right subject and class so it is ready when you start writing notes about it.
2
Set up your semester
Add your courses, subjects, and class schedule once. Katav builds the calendar, to-do list, and AI study plan around it — so every note you write lands in the right place.
3
Write your notes — let the AI close the gaps
Open a new class, write notes in your own words. Hit record when you want the AI to listen along, complete the gaps you missed, and flag anything you may want to double-check.
Coming from StudyFetch? Bring your saved flashcards and study sets in as PDFs or images and Katav will rebuild them as native flashcards — sitting next to the notes you actually wrote.
Honest answers to common questions
When you record a class, the AI reads what you wrote and compares it to the transcript. It can complete sections you left thin, add details you missed while you were busy writing, and gently flag passages where your notes may not match what the professor said — so you can review and decide.
Yes. Katav handles uploaded PDFs and slides the same way StudyFetch does — you can chat with them, generate flashcards, summaries, and quizzes. The difference is that those uploads sit inside a course → subject → class structure and live next to notes you wrote in your own words.
Yes. Katav has an AI tutor that answers questions grounded in your own notes, recordings, and uploaded materials. Spark.E is excellent at what it does over uploads; Katav's tutor adds your own notes and your full semester to that picture.
Yes. The free plan includes 3 hours of lecture transcription per month, and unlimited transcription if you are on iOS 26. You can upgrade later if you want more transcription hours, more storage, or higher AI usage, but you do not have to.
Katav is priced in your local currency where possible (USD, BRL, CAD, EUR). StudyFetch publishes prices in USD only, which for students outside the US often means worse exchange rates and taxes added at checkout.
