PROF. MENTHOR
explain question 4 from the slides
That's the Gibbs free energy one from Lecture 07, slide 12. You missed it twice this week. Let's redo it together.
Your study path

Five stops from lost to confident

Scroll down. The professor walks it with you.

STOP 01 · ASK ANYTHING

A professor who read your notes

Every answer is grounded in the material you uploaded: your lecture, your professor's wording, your exam scope. Not the internet's average opinion.

I already read your slides. Ask me anything.
01
Ask Prof. Menthor
reading Lecture 07 · 42 slides
why is ΔG negative here?
Because entropy grows enough to beat the enthalpy cost. Slide 12 shows it. Want me to walk the numbers?

1Identify the reaction order from the plot
2Plug k into the integrated rate law
3t½ = 138 s
Show me the question. I'll walk the steps.
02
STOP 02 · SNAP & SOLVE

Point your camera at the hard one

Photograph any question from a book, a past paper or the board. You get the reasoning step by step, never just the final number.

STOP 03 · UPLOAD & QUIZIFY

Slides in, quiz out in 60 seconds

Drop in a PDF or DOCX. Export your lecture deck as a PDF and it works the same. Up to 50 MB a file. Menthor writes the questions your professor would ask, then keeps drilling the ones you keep missing.

Hand me the PDF. Ten questions, sixty seconds.

STOP 04 · SUMMARISE

40 pages the night before? Fine.

One tap turns a chapter into the version you can actually revise from: the key points, without the padding.

STOP 05 · COMPETE

Studying alone is why you stop

Daily streaks, live rankings and a quiz code you can send your group chat. Menthor makes revision the thing you're competitive about.

Selin is 700 XP ahead of you. Shall we?

Three taps, then it's a habit

No setup, no folder system, no tutorial.

1

Feed him your week

Upload the slides, snap the whiteboard, forward the reading. Two minutes on Sunday.

2

Do your daily review

A short set from what you've already studied, picked from what you're closest to forgetting. Ask follow-ups any time.

3

Walk in already knowing

By exam week you've seen every weak spot four times. No all-nighter required.

Before you ask

A general chatbot answers from the internet. Menthor answers from your material: your lecture, your professor’s wording, your exam scope. And it remembers which questions you keep getting wrong.

PDF and DOCX files up to 50 MB, plus photos of questions from books, past papers or the board. Slide decks work too: export the deck as a PDF from PowerPoint, Keynote or Google Slides and upload that.

We’re letting students in from the waitlist in small batches so the professor stays fast. Join and you’ll get a TestFlight invite as soon as your seat opens.

Your uploads stay yours. You choose who can take a quiz you made, and we never use your content to train AI models.

It’s in the works. iPhone comes first, because that’s where studying actually happens. The same account will work on both.
