Why Notegral

The name

Notegral is note + integral, and both senses of the second word are meant. In everyday English, integral means essential, part of the whole. In mathematics, the integral sign ∫ in our logo does something specific: it sums infinitely many small pieces into one whole. That is the entire idea of the app. You collect hundreds of small pieces (a note here, a chapter there, a diagram, a definition) and Notegral's job is to integrate them: file them, connect them, and turn them into one body of understanding you can actually carry into an exam.

The gap every student knows

There are many notes apps, and they all stop at the same place: storage. You can end up with thousands of notes and no realistic way to retrieve the one you need, let alone revise them systematically. And storage was never the hard part. No mainstream notes app gives you tools to expand your understanding, crystallize concepts, and retain information over months. Reading a note you wrote in October does not mean you will remember it in June.

The newer tools have the same gap from the other side. NotebookLM and ChatGPT are excellent ways to generate notes, and Notegral does not compete with that. But they give you no way to organize what they produce, no structure across notebooks and chats, and no path from a good note to a retained concept.

What Notegral actually does

Notegral is built around efficiency: minimum input, maximum output. One note can become flashcards, a quiz, a mind map, and a graded self-explanation, without you rewriting anything. The focus throughout is connected concepts and a deliberate strategy for revision and retention, not a prettier pile.

Getting your notes in

• Write them in Notegral, with the notation tools and sketchpad above.
• One-click import from NotebookLM with the browser extension (Chrome, Edge, Brave, Firefox).
• Paste from ChatGPT or anywhere else; structure is preserved.
• Add PDF, Word and other files; read PDFs page by page and clip passages straight into notes.
• Import from Notion, Evernote and Markdown.

Write H₂O₂ without leaving the sentence

Every science student knows the tax: you are mid-sentence, you need a subscript, and now you are hunting through an insert menu, or memorising LaTeX, or giving up and writing H2O2 and hoping the examiner forgives you.

In Notegral you type it as you would say it. H2O2 becomes H₂O₂, x^2 becomes x², Ca2+ becomes Ca²⁺, SO4^2- becomes SO₄²⁻. A small preview appears beside the word with the key that takes it, you press Tab, and you keep typing in the same sentence. Whole equations work the same way: H2O2 + CO2 = H2CO3 on a line of its own converts with Enter. A backslash names any symbol, and you only need the start of the name: \equi gives ⇌.

What makes it usable every day is what it refuses to do. It never converts anything on its own, and it stays quiet on the things that only look like chemistry: vitamin B12 stays B12, the C4 vertebra stays C4, COVID19 stays as it is. If it offers when you did not want it, Esc waves it away and your text is left exactly as typed. The result is ordinary text too, not an embedded object, so it survives copying, printing, flashcards and export.

When one line will not hold it, press Cmd+E, or Ctrl+E on Windows, and the equation editor opens where you are. Search for what you want by the word you would say for it, fraction or integral or matrix, and it arrives with empty boxes to fill. Tab walks the boxes, so you write a fraction in the order you would say it and never count a brace. Chemistry is in there too, reaction arrows and states of matter and all.

Your notes, your data

Notes live on your device first, in your browser's own database, so the app is fast and works offline. Sign in and they also sync to secure cloud storage, following you across browsers and devices, with autosave as you type, a Trash that holds deleted notes until you are sure, and automatic backups into a folder you choose, so your notes also exist somewhere other than a browser. Sign-in uses Google's own page; Notegral never sees a password. AI features send only the text of the note you are working on, only when you use them, and your notes are never sold or used for advertising.

Your rights are just as plain: everything you have created, uploaded files included, downloads as a single archive whenever you like (Full backup, in Settings), and deleting your account (open Settings, then Delete account) erases everything, from the cloud and your device, at once and for good, cancelling any subscription with it. Nothing is kept back, and you never have to email anyone to ask. The details are in the Privacy Policy.

And honestly, fun

Because studying should not feel like filing taxes, there is dark mode, a keyboard-first drill mode, and Iffy mode, which hands every drawing in the app to a magical, sunny poodle. Qualifications: none. Enthusiasm: total.

How it compares

Designed with students, priced for students

The interface was shaped by real students preparing for international exams: what earned a place on the screen is what helps under time pressure, and everything else was cut. The pricing follows the same logic. Notegral is free to start, storage plans are cheap, and AI tutor credits are affordable, because the business model is built for students who would rather spend their money on pizza and coffee than on yet another academic subscription. We think that is the correct order of priorities.
