Verba volant,scripta manent
Spoken words fly away.Your notes stay.
Upload the recording of your lecture. Alessandria transcribes it and turns it into structured notes, a glossary, a concept map, a timeline, quizzes and flashcards. You get it back ready to study.
Your first two lectures are free. No credit card needed.
The endocrine system
Demo animation: from an audio file or a text file the notes page writes itself. The full text of the example is below.
The endocrine system
What the endocrine system is
A network of glands that communicate not through nerve impulses but through chemical messengers: hormones, released into the blood and reaching only the cells that carry the right receptor.
The nervous system is fast and local; the endocrine one is slower but pervasive, holding the deep balances: growth, metabolism, reproduction, the stress response.
The hypothalamus–pituitary axis
The hypothalamus is the control unit: it reads the body’s state and issues orders to the pituitary, a pea-sized gland at the base of the brain.
Anterior lobe: makes GH, TSH, ACTH, FSH, LH and prolactin.
Posterior lobe: releases oxytocin and ADH, made upstream by the hypothalamus.
The feedback mechanism
Nearly every hormonal axis runs on negative feedback: when the target hormone rises, it shuts off the signal that called for it — like a thermostat cutting the boiler once the room is warm.
Thyroid: TRH → TSH → T3 and T4, which in turn brake TRH and TSH.
Adrenal: CRH → ACTH → cortisol, with the same restraining return.
One example worth keeping
Fasting, blood sugar drops: the pancreas releases glucagon, the liver frees glucose, sugar climbs back. After a meal it rises: insulin steps in, cells absorb, it settles. Two opposite hormones, one value held steady.
The lecture’s key idea: the endocrine system doesn’t chase peaks, it defends balances.
While you write, you don’t listen. While you listen, you don’t write.
That is the bargain of every lecture, and you pay for it twice: once in the room, once at home, replaying the recording at double speed hoping to find that one sentence again.
Replaying an hour of audio is not studying. Alessandria turns that hour into clear pages, ready to read and revise. The time you would have spent goes into actually studying.
Not a summary: a small volume.
From a single recording, Alessandria builds every piece you need to study that lecture.
Structured notes
Topics split into sections, with the points that matter highlighted. They stay in the course, ready to read whenever you want.
Glossary
Every technical term mentioned in class, defined from the context your professor used it in.
Concept map
The concepts of the lecture linked together: open and close branches, search a concept, zoom in, and view the same map in four different shapes or step through it one concept at a time.
Timeline
The milestones of the lecture one after the other, grouped into periods, each with its own “why it matters” and with the time that passes in between. At a glance you see where the lecture starts and where it lands.
Quizzes and flashcards
Scored multiple-choice quizzes to check you actually understood, plus flashcards — one concept each — reviewed with the answer hidden until you uncover it.
Search and ask
Find any concept across every lecture in the course, and ask questions about your material: answers come from your lectures, not from the web.
Three steps, then nothing.
Upload the lecture
Audio in mp3, m4a, wav, ogg, opus, flac and aac — iPhone Voice Memos included. A plain text file works too.
Alessandria processes it
Transcript, notes, glossary and map arrive one after the other and you see them appear. Keep the page open until it finishes.
Study and revise
Everything stays organised by course and by lecture. Come exam time, the course tools work across the whole term at once.
Come exam time, the whole term.
Eight tools that do not look at a single lecture: they read every note in the course and work on all of it.
Exam Super-Summary
All the course material condensed into one file, built for final revision.
Exam Simulation
Open questions with model answers, across the whole syllabus.
Multiple-choice quiz
Multiple-choice questions on the entire course, scored and explained.
Term-wide map
One large map linking the themes of the whole course, including the classic cross-topic questions.
Course timeline
The whole term in order, from the first lecture to the last: the milestones, the phases and the links between them.
Course flashcards
A deck of cards drawn from every note in the course, one per concept: the more lectures, the more cards.
Study roadmap
A day-by-day study plan with real dates, based on the days left before the exam.
5-minute briefing
The key concepts, the common thread and the typical questions, in five minutes of reading.
Three things it will never do.
It doesn’t make things up.
Only what was said in the room ends up in your notes. Not one extra date, not a definition pulled from who knows where, not an author who simply sounds right.
If your professor didn’t say it, it isn’t in there.
It doesn’t eat half the lecture.
From the first minute to the last, including that long explanation in the middle that nobody ever manages to write down in full.
It isn’t a few lines of summary: it is your lecture, written.
It doesn’t ask anything of you.
No keys to obtain, no settings to figure out, no prompt to invent: you upload the recording and never touch anything again.
Leave the page open: Alessandria takes care of the rest.
Whatever your method is.
You attend a lot of lectures
No more re-listening to hours of audio: you read them in minutes, already sorted course by course.
You are preparing an exam
Exam summary, simulation, quizzes and study roadmap work across the whole term, not on a single lecture.
You read better with dyslexia
A high-legibility typeface and a dyslexia mode with wider spacing, built in — you do not have to ask for them.
You study on your phone
It opens in your phone browser just like on a laptop: nothing to install, always the latest version.
Same hours, a different result.
The comparison isn’t only with your notebook: it’s with you, at eleven at night, pasting chunks of a transcript into a chat.
The old way
- You replay the recording twice so you do not miss anything
- You rewrite everything by hand
- While you write you are not listening, and something slips past
- You hunt for notes scattered across files and notebooks
With any chatbot
- Long audio gets refused
- The text doesn’t fit: you paste it in pieces, and each piece loses the thread
- You rewrite the prompt every time, and every time the format comes out different
- When it makes something up, nobody tells you
- In the end you have a very long chat. Not a notebook
With Alessandria
- You upload the file and that’s it: the whole lecture, first minute to last
- The same materials, in the same format, for every lecture
- What wasn’t said doesn’t get in
- You listen to the lecture as it happens, without chasing it
- In the end you have the course in order: search a word and find the lectures where your professor talked about it
Your notebook is still useful: writing helps you understand. Alessandria takes care of the rest.
Made to be read by everyone.
Alessandria uses Atkinson Hyperlegible, a typeface designed specifically for high legibility, and has a dyslexia mode that widens the space between letters and words. It is not an option buried in the settings: it is how the app is built.

What people ask us.
What files can I upload?
Audio recordings (mp3, m4a, wav, ogg, opus, flac, aac) and text files. A lecture is either audio or text: PDFs, images and video cannot be uploaded.
Do I have to install anything?
No. Alessandria opens in your browser, on desktop and phone, and is always on the latest version. You can also add it to your phone’s Home screen.
Do I need to set up anything for the AI?
No. It is included in the service: no accounts on other sites, no keys to copy anywhere. Open it, upload the lecture, done.
Can I close the page while it works?
Not yet — the page has to stay open until it finishes, because the work streams to your browser as it goes. You can use other tabs, just do not close Alessandria’s.
What language does the material come out in?
The language the lecture was given in. The interface, on the other hand, is up to you: Italian, English, German, Spanish, French or Chinese.
Does my material stay mine?
Yes. Recordings and documents live in your own space and are processed only to build your study material.
Write to us, we answer.
A doubt, a problem, an idea for the next feature: two lines are enough.
Built by students, for students.
Alessandria was born in a student room, because we wanted to follow the lecture all the way through — and find it again, in order, when it was time to study.
The name comes from the Library: the place where everything worth keeping ended up.
Spoken words fly away. Your notes stay.
Stop transcribing by hand.
The first two lectures are free. It takes two minutes to try.
