The problem with taking notes in a lecture is that you cannot listen and write at the same time; the problem with the slides afterwards is that they were never meant to be read alone. Nuutli solves the second problem so you can stop doing the first. Upload the lecture deck and it is rewritten as notes that explain each point in a sentence, keep the lecturer's numbers and definitions exactly, and fold in the speaker notes when the deck has them. Choose Cornell notes to study with cue questions, a summary to catch up on a missed lecture, or flashcards and a quiz for the exam. It works for medicine, nursing, law, engineering, business, psychology, history, any course that runs on slides, in the language the slides were written in.

Real example
An organic chemistry lecture, slides to Cornell notes
Cornell notes give each topic cue questions, notes and a summary. The cue questions are written from the content, so they test what the lecture actually covered.
Slides in
- Slide 14: SN1 vs SN2: the mechanisms
- - SN2: one step, backside attack, inversion of configuration
- - SN1: two steps via carbocation, racemisation
- Slide 15: What favours each
- - SN2: methyl > primary > secondary; strong nucleophile; polar aprotic solvent (DMSO, acetone)
- - SN1: tertiary > secondary; weak nucleophile; polar protic solvent (water, ethanol)
- - Rate: SN2 = k[RX][Nu], SN1 = k[RX]
- Slide 16: Common exam traps
- - Tertiary halides never go SN2 (steric hindrance)
- - Rearrangements (hydride and methyl shifts) only in SN1 carbocations
Notes out
SN1 vs SN2 mechanisms
Cue questions
- How many steps does each mechanism take, and what happens to stereochemistry?
- Which substrates, nucleophiles and solvents favour SN1, and which favour SN2?
- Why can a tertiary halide not react by SN2?
Notes
- SN2 is a single step: the nucleophile attacks from the back side and the configuration inverts.
- SN1 takes two steps through a carbocation intermediate, which gives racemisation.
- SN2 is favoured by methyl > primary > secondary substrates, a strong nucleophile and a polar aprotic solvent (DMSO, acetone). SN1 is favoured by tertiary > secondary substrates, a weak nucleophile and a polar protic solvent (water, ethanol).
- Rate laws: SN2 rate = k[RX][Nu]; SN1 rate = k[RX].
- Exam traps: tertiary halides never go SN2 because of steric hindrance; hydride and methyl shifts (rearrangements) happen only in SN1 carbocations.
Summary
- SN2 is one concerted step with inversion, favoured by small substrates, strong nucleophiles and aprotic solvents. SN1 goes through a carbocation, racemises, can rearrange, and is favoured by tertiary substrates, weak nucleophiles and protic solvents.
How it works
Make notes from this lecture in three steps
- 1
Get the deck
Download the lecture from the course site (PPTX or PDF) or copy the Google Slides link your lecturer shared.
- 2
Choose how you will study
Cornell notes to review with cue questions, a summary to catch up, flashcards or a quiz before the exam, a study guide for the whole unit.
- 3
Download and revise
Read the notes on the page, download Word or Markdown, and run the same deck again in a second style when the exam gets close.
How to take notes from slides without retyping them
Retyping slides is the most common way students waste a study session: an hour of copying produces a document that says exactly what the deck said, and nothing was learned on the way. The point of notes is the rewriting, not the copying. Good notes from slides explain each bullet in a sentence, connect the slides that belong together, and keep the facts you will be tested on exactly as the lecturer gave them. Nuutli does that part in 30 seconds so your time goes into reading and testing yourself.
The format should match the moment. During the term, a summary of each lecture read the same day is enough to make the material familiar. Two weeks before an exam, Cornell notes turn the same content into questions you can cover and answer. The week of the exam, flashcards and the multiple-choice quiz find the gaps. Running the same deck in a second style costs nothing and is the single most useful habit.
- Ask the lecturer for the .pptx rather than the PDF; the speaker notes often contain the explanation that was said aloud.
- Add your own line under any point the lecturer stressed in class; the Word download is fully editable.
- For a missed lecture, read the summary, then the Cornell version, before looking at a friend's notes.
In short
To turn lecture slides into notes, upload the deck to Nuutli and pick a style: Cornell notes for active recall, a summary for catching up, flashcards or a quiz for exams. It reads slide text, tables and speaker notes, keeps every fact exact, and returns notes in about 30 seconds as Word or Markdown. Free, no sign-up.

Frequently asked questions
How do I turn lecture slides into notes?+
Upload the lecture deck (PPTX, PDF or a Google Slides link) to Nuutli, choose a note style and click Make notes. The slides are rewritten as study notes in about 30 seconds, with every fact kept exactly, ready to download as Word.
Is there a free AI for lecture slides to notes?+
Yes. Nuutli is free for three decks a day, up to 80 slides each, with every note style and the Word download included. No account is needed.
Which note style should I use for lectures?+
Summary to catch up on a lecture, Cornell notes to revise with cue questions, flashcards or the quiz in the final week, and the study guide for a whole unit. Running one deck in two styles is common.
Does it work for medical and nursing lectures?+
Yes. Drug names, doses, values and classifications are kept exactly as the slides state them, and the reviewer and flashcard styles are made for memorisation-heavy courses.
Can I upload several lectures at once?+
One deck per run. For a unit of several lectures, run each and keep the Word files together, or merge the decks into one PDF of under 80 pages first.
What if the slides are in another language?+
The notes come back in the language of the slides, headings included. French slides give French notes, Arabic slides give Arabic notes with right-to-left text in the Word file.
Will the notes include what the lecturer said?+
Only what is in the file: slide text, tables and speaker notes. If your lecturer writes their explanation in the speaker notes, it is included. Spoken remarks that were never written down cannot be recovered from the slides.
