My professor switches between English and Italian mid-lecture. Other tools dropped the Italian. Classp keeps both — and translates to Spanish live.
Every lecture,
fully understood.
Classp transcribes, translates, and summarizes your lectures in real time — so you can focus on learning, not note-taking.

- Cristae increase surface area for the electron transport chain.
- More surface = steeper proton gradient = more ATP produced.
- ATP synthase converts the gradient into chemical energy.

Stay with your professor, not the notes.
These 75 minutes don't rewind. Classp captures every one.
Listen14:32
Every word, kept up with.
A clean live transcript that catches what your professor said — even when you didn't. Toggle on translation any time; your language streams alongside the original.
- Sub-200 ms transcription latency
- LLM cleans up dropped words and broken sentences
- 50+ translation languages, toggle any time
Understand14:35
See the key idea before the next slide lands.
As the lecture unfolds, a second pane builds Key Concepts, Main Points, and Details. Glance over to catch the thread when you drift.
- Auto-refreshes as the lecture builds
- Three-tier structure: Concepts / Points / Details
- Outputs in your translation language too
Ask14:38
Ask in the moment. Quietly.
Tap and type when something flies past. Classp answers using the last few minutes of transcript plus any slides you uploaded — grounded in your professor's words, not the open internet.
- Upload PDF / PPT / Word slides for richer context
- Streams back in seconds; never interrupts the transcript
- Saved as “In-class Q&A” for later review

Key Concepts

Main Points
- 1. ETC pumps protons across inner membrane
- 2. ATP synthase converts gradient...
What did he just mean by entropy?
A measure of disorder. Systems naturally drift toward more disorder until they hit equilibrium.

My finance prof talks at 180 wpm. I used to re-listen at 0.7x for hours after class. Now the Korean keeps up live — first semester I'm not lost.
I used to translate my professor's English in my head and miss what came next. Now the 中文 transcript shows up live — I just listen.
