Extracts insights from YouTube transcripts, goes beyond summaries.
I've written an article about this on Medium. I want to take my learnings and make a Chrome extension of this script that can place these insights beside the YouTube videos itself.
- Clone the code and run
yarn install - Set the API key from OpenAI in env:
export OPENAI_API_KEY=abcd - Modify the Youtube video link
YOUTUBE_URLin the script - Run
node index.jsand once complete, openconversation.txt
This is the primary code flow of the script:
// uses youtube-transcript npm module
const transcript = await fetchTranscript(YOUTUBE_URL);
// because of limited context window of GPT,
// split the text into chunks
const chunks = await splitText(transcript);
// run GPT on each chunk
const conversationChunks = await Promise.all(
chunks.map((chunk) => convertToConversation(chunk))
);
const conversation = conversationChunks.join("\n\n");
// write the stitched chunks back to a file
await writeStringToFile("conversation.txt", conversation);And then how to prompt the GPT-3 API:
const chat = await openai.createChatCompletion({
model: "gpt-3.5-turbo",
messages: [
{
role: "user",
content: transcript,
},
{
role: "system",
content: `The above is a transcript of a YouTube video.
Label the statements and reformat it as a conversation.`,
},
],
temperature: 0,
});
const conversation = chat.data.choices[0].message.content;Follow me on Twitter for updates: @paramaggarwal
