Watch the lecture.
We capture the notes.
Turn any YouTube or course video into visual study notes with real slides, diagrams, and text — so a 1-hour lecture doesn't become 2 hours of note-taking.

Lecture 8: Photosynthesis Processes
Extracted from 54m video • AI formatted visual notes
The process starts when light energy is absorbed by pigments inside the plant's chloroplast. Water molecules ($H_2O$) are split to release oxygen ($O_2$), generating energy carriers used to synthesize sugar.
- Chloroplast contains chlorophyll to capture solar energy
- Light reactions take place across the thylakoid membranes
- Inputs: Water ($H_2O$), Carbon Dioxide ($CO_2$), and minerals
Detailed layout of chloroplast reactions. The Light Reactions occur in the thylakoid grana, producing ATP and NADPH. These products are then utilized inside the fluid stroma for Dark Reactions (Calvin cycle) to synthesize food glucose ($C_6H_12O_6$) from Carbon Dioxide ($CO_2$).
Video Summary: Photosynthesis
Generated text summary • No visual extraction
Overview
This lecture covers Photosynthesis. Light energy is captured by chlorophyll inside chloroplasts. Water ($H_2O$) is split to produce energy, and Carbon Dioxide ($CO_2$) is converted to sugar glucose inside the stroma. The detailed biological structures, chemical cycles, and whiteboard sketches from slides must be referenced by watching the video.
Key Points
- [14:32] Light reaction occurs in thylakoid membranes, splitting water to release oxygen. (No image • watch video).
- [28:09] Dark reaction uses ATP and NADPH in the stroma to synthesize glucose from CO2. (No image • watch video).
Students learn from video — but can't take notes at the same time
Millions of students watch YouTube and course lectures daily. Note-taking while listening wastes time, breaks focus, and forces you to miss visually important moments.
1 hour lecture → 2 hours studying
Pausing, rewinding, and handwriting notes doubles your study time and breaks your focus.
You miss what matters
While you write, the lecturer moves on. Key diagrams, equations, and examples slip past.
Summaries aren't enough
Text-only AI tools skip the visuals. You still have to rewatch the video for slides and diagrams.
VideoSlides solves it — notes with real images, not fake ones
Unlike NoteLM and text summarizers, we pair structured notes with frames pulled straight from your lecture.
Real images from your video
We extract actual slides, whiteboard frames, and diagrams — never AI-generated replacements.
Structured notes + AI editor
Get text and visuals together. Edit with prompts — translate, simplify, or reorganize instantly.
Quick revision, not rewatching
Turn a full lecture into visual study notes in under 60 seconds. Revise before exams in minutes.
How it works
