FOR THE “I'LL WATCH IT LATER” GENERATION

Less scrubbing.
More getting it.

Turn your next coding tutorial into a lesson you can read. Follow the explanations and changing code, one 5–10-minute chapter at a time.

MY NEXT AHA / CHAPTER 01

Wait. That actually
makes sense.

Turn each character into a number. Then turn the numbers back into the exact same text.

text = "aha!"
ids = encode(text)
decode(ids) == text  # True

Big lecture.
Notebook energy.

SOURCE

VIDEO OR PUBLISHER LINK

Read public captions and video screens, then write locally. If captions are missing, transcribe the recording locally. Source availability varies by video.

HOW MUCH TO CONVERT

Long course? Start with one 5–10 minute chapter. Choose its start timestamp, then continue with the next chapter. Full-video conversion is experimental and can take much longer.

START

WINDOW

Transcript & screen evidence Add source

If automatic caption retrieval fails, import or paste timestamped transcript text. A title alone cannot reconstruct a lesson.

You can also paste timestamps and text copied from a transcript. Example: 0:00 First explanation, then 0:12 Next explanation.

CAPTIONS / VTT, SRT, TXT OR JSON OR PASTE TIMESTAMPED CAPTIONS SCREEN RECORDS / JSON

Code states, outputs, diagrams, and frames with timestamps.

A combined file can contain segments and evidence. Its timestamps must match the video.

WRITING ENGINE

●Looking for a running model…

Screen reading, writing, and content review run locally. No model API key is needed.

Your study notes stay on this device. Creator attribution stays with your exports.

OR TRY THE WORKING SAMPLE

Original 8-minute lesson. Real local-model prose, with all six code states preserved. Not a Karpathy transcript.

Your next aha
belongs here.

Your written chapter will live here: explanations in order, evolving code beside the reasoning, and links back to the moment it was taught.

VIDEO + SOURCE→LOCAL WRITING→STYLED PDF

Paste a lesson, pick a chapter, and let’s connect the dots. Or open the sample to take a look around.

03 / TAKE IT WITH YOU

Make it yours.

One complete chapter.
Three ways to read it.

HOW WILL YOU USE IT?

Complete explanations and readable code. No video screenshots or repeated timestamps.

Add section timestamp links

FORMAT: A4 PDF
CONTENT: Full written lesson
CODE: Readable code blocks
LINKS: Optional timestamps

Create or open a chapter first. Changing layout never shortens the lesson.

OPEN AN EXPORTED CHAPTER

Reopen an evidence JSON file to read or export again without rerunning the model.

What happens here?

1. Read the supplied captions and screen records.
2. Write with the selected model.
3. Check source coverage and export.

A local model needs no API key. Missing source material still needs to be supplied.
