You watch hours of videos.
You remember almost none.

Not because you were not paying attention. Because watching and learning are different things. This is what Ravenote does about it.

You finished the lecture. You have nothing to show for it.

One button. Ravenote reads the transcript and writes the notes. Not a summary. The actual things you would have written yourself if you were fast enough and paying full attention the whole time.

  • Pulls from the full transcript, not a high-level overview
  • Extracts the specific concepts your brain needs to hold onto
  • Takes about 10 seconds per lecture
Lecture 7 · Networking Basics
TCP/IP — packets route independently through the network
DNS resolves domain names to IP addresses before requests
Latency = travel time per packet. Bandwidth = throughput.
TCP/IP DNS Latency Bandwidth

Watching is not the same as understanding.

You can sit through an hour of content and understand almost none of it. After your notes are ready, Ravenote asks you a few questions about what was just taught. Not to grade you. To show you which parts actually landed.

  • Questions come from this specific lecture, not a generic bank
  • You find out right away which parts did not stick
  • Every answer updates your concept scores so nothing stays invisible
Check your understanding
What does DNS do before a network request is sent?
A
Translates the domain name to an IP address
B
Breaks the request into smaller packets
C
Encrypts data before transmission
D
Measures network latency and bandwidth

You think you know it. Prove it.

The gap between "I watched that lecture" and "I actually know that concept" is where most learning disappears. Ravenote tracks that gap for every concept across every lecture in the course. The bars do not lie.

  • Each concept gets its own score, updated after every quiz
  • Tracked across the whole course, not just one lecture at a time
  • Built on SM-2, the same algorithm serious flashcard apps use

You have rewound that same 30 seconds four times.

The instructor explained it clearly. You still do not have it. Ravenote notices when you keep going back to the same section and offers to explain that exact concept using completely different language. Not a repeat. A different angle.

  • Triggers automatically after 3 rewinds on the same section
  • Fresh explanation, not a copy of your notes
  • Tap the badge or ignore it, it does not get in the way

You rewound that 3 times. Want me to explain it a different way?
Breaking it down
Think of subnetting like floors in a building. The IP address tells you the building (network) and the room (host). The subnet mask says how many floors exist and which rooms belong to each floor.

Learning Spanish is nothing like learning system design.

Generic notes do not work for everyone. Tell Ravenote what you are actually trying to get out of the course and it adjusts how it takes notes, what it pulls as concepts, and how it writes quiz questions. Once. Then it just works that way.

  • Language mode drills vocabulary and usage, not theory
  • Technical mode goes deep on how things work, not just what they are
  • Change it anytime if your goal for a course shifts

When it will not help you

Better to know upfront than find out after installing.

Your team standup or Zoom call. Ravenote reads recorded video transcripts. It does not join meetings or record live audio.
Videos with no captions. The notes come from the transcript. If there is no transcript, there is nothing to work with.
Firefox, Safari, iOS, Android. Chrome extension only. Brave, Arc, and Edge work too.
Completely free forever. The free tier covers 3 videos. After that you need Pro or your own OpenRouter key.

3 videos free. No account needed.

Install it, open a lecture you have been putting off, and find out if it is actually useful for how you learn. Takes 30 seconds to set up.

Add to Chrome, it is free See pricing
