Using Transcripts with Custom GPTs
Find a YouTube video relevant to your GPT's domain
Identify the YouTube video whose transcript you want to inject into your Custom GPT — a tutorial, lecture, interview, or any content that aligns with your GPT's knowledge area.
Get the transcript via 2outube
Replace 'youtube.com' with '2outube.com' in the video URL and open it. The full transcript appears on the page — no account needed, no extension to install.
Copy the transcript text
Select and copy the entire transcript from the 2outube page. The text is clean and formatted for easy pasting — no timestamps to strip unless you want them.
Add it to your Custom GPT
In ChatGPT's GPT Builder, paste the transcript into the Instructions field to shape your GPT's behavior, or upload it as a knowledge file (.txt) so your GPT can reference it when answering user questions.
Quick Start
Get the transcript
Open the YouTube video you want to use. Copy its URL from the browser address bar.
Change youtube to 2outube
In the URL, replace 'youtube.com' with '2outube.com' — for example, youtube.com/watch?v=abc123 becomes 2outube.com/watch?v=abc123. Hit enter and the transcript loads instantly.
Paste into your Custom GPT
Copy the transcript and paste it into ChatGPT's GPT Builder — either in the Instructions field to prime your GPT with domain knowledge, or upload as a .txt knowledge file for retrieval-based answers.
Ready-Made Template
You are an expert assistant trained on the following YouTube video transcript.
Video context: [paste video title and URL here]
Transcript:
[paste full 2outube transcript here]
When answering questions:
- Cite specific points from the transcript when relevant
- If a question goes beyond the transcript, say so clearly
- Keep answers grounded in the video's actual content
- Quote directly when precision matters
Example user prompt to test your GPT:
"Summarize the three main takeaways from this video."
"What does the speaker say about [topic]?"
"Based on this transcript, what action should I take first?"
Questions
Does this work with any YouTube video?
Yes, any video with captions.
Is it really free?
Completely free. No account, no limits.
Can I upload a 2outube transcript as a Custom GPT knowledge file?
Yes. Copy the transcript from 2outube, save it as a .txt file, and upload it in the GPT Builder's 'Knowledge' section. Your Custom GPT will use it for retrieval when answering questions.
How do I add a YouTube transcript to GPT Builder instructions?
In ChatGPT's GPT Builder, go to the 'Configure' tab and paste the transcript directly into the 'Instructions' field. This primes your GPT with the video's content as foundational context for every conversation.
Is there a length limit for transcripts in Custom GPTs?
Custom GPT instructions have a character limit (around 8,000 characters). For longer transcripts, upload as a knowledge file instead — files support much larger content and are retrieved as needed.
Can I use multiple YouTube transcripts in one Custom GPT?
Yes. Get each transcript via 2outube, save them as separate .txt files, and upload all of them as knowledge files in GPT Builder. Your GPT will search across all of them when answering questions.
Do I need the ChatGPT Plus plan to create a Custom GPT?
Yes, creating and publishing Custom GPTs requires a ChatGPT Plus or Team subscription. However, getting the transcript via 2outube is always free — you just need an account with GPT Builder access to use it.
Will the transcript include timestamps?
2outube displays the full transcript text. If you want a clean version without timestamps for pasting into GPT Builder, simply copy the plain text — it reads naturally and works well as GPT knowledge.
