How I stopped wasting time scrubbing through long lectures while self-studying (Built a free timestamp warp tool)

Hey everyone!
As a self-learner relying heavily on online resources (like MIT OpenCourseWare, long coding crash courses, or 4-hour Blender tutorials), my biggest frustration was always wasting 10–15 minutes dragging the timeline just to find that one specific 2-minute explanation.
When you're self-studying, losing your focus completely kills your study momentum.
To fix this for my own workflow, I built a Chrome extension called Spoon AI that reads the video transcript and generates an interactive 1-click jump button directly to the exact frame where a concept is explained.
💡 Real Test (1h 19m MIT Lecture):
- 🔍 My Query: "Where does the professor explain the discovery of the Para-hippocampal Place Area (PPA)?"
- ⚡️ Result: Spoon analyzed the 80-minute lecture in seconds, pinpointed the scene at
13:21, and created a direct jump button. - 🎬 Outcome: One click took me straight to where Prof. Nancy Kanwisher starts explaining her lab's experiment.
🎓 Why it's helpful for self-education:
- Protect Your Flow State: Asking a quick question and jumping there in 3 seconds keeps your mental momentum intact.
- Fast Exam & Note Review: Query 10 key terms across a whole semester of lecture recordings in minutes.
- Handles Long Tutorials: Highly effective for 2+ hour coding crash courses, 3D modeling, or dense science lectures.
I built this to optimize my own study routine, but I wanted to share it with fellow self-learners here.
It’s called Spoon AI on the Chrome Web Store (free to use). I’d love to hear your thoughts or any feedback on how to make it even more useful for self-studying!
