How it works
1
Upload your notes
Slides, PDFs, Word docs or text. Any subject.
2
Take a quick check
Add your test date and answer a few questions. Your answers show Navri what you still need to learn.
3
Follow tonight's plan
A short plan every night until the test, built around your weak spots.
Everything you need before a test
One app, built around your own notes.
Know exactly how long you've got
Add your test date and Navri counts down, then builds a short plan for each night from your weakest topics. The night before, it switches to a final practice test.

Why does the Krebs cycle need oxygen?
From your courseIt doesn't use oxygen directly, but the electron transport chain does. Without oxygen, NADH builds up and the cycle stops…
Flashcards that make themselves
Every key term in your notes becomes a card. Cards you find hard come back sooner, so you remember more in less time.

Why not just re-read your notes?
Re-reading feels productive but it's one of the weakest ways to study. Here's how Navri compares.

Everything Navri does, explained
Navri is built around one idea: before a test, you should know exactly what to study. Here's every part of it.
The core
Exam countdown and tonight's plan
Add your test date and your home screen becomes a countdown. Every night, Navri builds a short plan from your weakest topics and past mistakes, usually 20 to 30 minutes.
One clear plan per night, so you never wonder what to do
The plan changes as you improve
The night before, it switches to a final practice test and a short review list

Course Brain: a map of your course
Upload what your teacher gives you, like slides, PDFs, Word documents or typed notes. Navri reads all of it and pulls out every unit, topic and key term, with definitions taken from your own material.
Works with PDF, Word, PowerPoint, text and more
Reads long documents, around 150 pages per file
Your notes stay private to your account
Scanned pages and photos of handwriting can't be read yet. Use files with real text.
Unit 4 · Cellular respiration7 terms
Unit 5 · Genetics9 terms
Unit 6 · DNA and proteins6 terms
AI tutor
Navi, a tutor that has read your notes
Ask Navi anything, any time. It answers from your own notes first and shows which file the answer came from. If something isn't in your notes, it tells you instead of guessing.
Explains step by step, then checks you understood
Quick buttons: explain simpler, give me a hint, quiz me, why was I wrong?
Free: 10 AI answers a day. Pro: up to 150
Like any AI, Navi can make mistakes. Check important facts against your notes.
Can you explain meiosis simpler?
From your course · Unit 5 notesSure. Meiosis is how your body makes sex cells. One cell divides twice, so you end up with four cells, each with half the chromosomes…
Quiz me on it
Memory
Flashcards that make themselves
Every key term from your notes becomes a flashcard automatically. Rate each card Again, Hard, Good or Easy, and Navri decides when you see it next, so the cards you struggle with come back sooner.
No typing out cards by hand
Study what's due, your weakest topics, or shuffle everything

For parents
Built for students. Trusted by parents.
Navri uses your teen's own class notes to show them what to study each night before a test, so their study time goes further.
What Navri does
📅
Plans every night
Your teen adds the test date. Navri counts down and builds a short plan for each night, focused on what they don't know yet.
📚
Uses their real notes
It works from the slides and notes their teacher gave them, for any subject: sciences, math, social studies and more.
🧭
Finds the weak spots
Practice questions show which topics need work, and mistakes keep coming back until they're fixed.
Is it just a way to get answers?
No. Navri is designed to teach, not do the work for them. Navi, the built-in tutor, explains things step by step and then asks a quick question to check understanding. Our Terms of Use ask students to use Navri to learn, and never during tests or to hand in work that isn't theirs.
Privacy and safety
Your teen's notes, courses and progress are private to their account.
No ads, and we never sell personal information.
Questions asked to Navi, with short excerpts from their notes, are processed by our AI provider, Anthropic, to generate answers.
Navri is for students aged 13 and older. Students under 18 should use it with a parent or guardian's permission.
You can ask us to delete the account and all its data at any time.
What it costs
Navri is free to start. Navri Pro is optional and can be cancelled any time.
