I built TubeWords — a free tool to transcribe any YouTube video and get an AI summary in seconds

 Every once in a while you watch a long YouTube video — a conference talk, a tutorial, a podcast — and you just want the gist. Or maybe you want to search through what was actually said. Or save a clean transcript to your notes.

I kept reaching for a tool like that and kept not finding exactly what I wanted. So I built it.


What is TubeWords?

TubeWords is a free, no-signup tool that does two things:

  1. Extracts the full transcript of any YouTube video, powered by Whisper AI
  2. Generates an AI summary of the content, so you get the key points without watching the whole thing

Paste a URL. Get your transcript. Done.

It supports timestamps or plain text output, so you can grab exactly the format you need — whether you're taking notes, building context for a prompt, or just skimming what was said at minute 12.


Why I built it

Honestly? Laziness in the best sense.

I watch a lot of technical content — conference talks, deep-dive tutorials, dev discussions — and I often want to reference what was said without rewatching. I also found myself copying transcripts into Claude or GPT to get a quick summary, which felt like unnecessary friction.

I wanted one place where I paste a URL and immediately get:

  • A clean, readable transcript
  • A concise summary
  • The ability to copy either one with a click

That's it. No accounts. No paywalls. No AI upsell features I'll never use.


The tech behind it

  • Whisper AI for the transcription — it handles accent variety and audio quality better than YouTube's auto-captions in most cases
  • Groq for the AI summary — fast inference, low latency, genuinely good summaries
  • Available in English and Spanish 🇨🇱

There's also a CLI 🖥️

If you live in the terminal (like I do when I'm in flow), there's an npm package:

npm i -g tubewords
Enter fullscreen mode Exit fullscreen mode

Then just:

tubewords https://youtube.com/watch?v=VIDEO_ID -o notes.md
Enter fullscreen mode Exit fullscreen mode

It fetches the transcript, generates the summary, and saves it to a markdown file. Super useful when you want to pipe YouTube content directly into your notes or your own tooling.


What's next

This is v1.0.1 — it works, it's stable, but there's more I want to add:

  • Chapter-aware summaries
  • Export to Notion / Obsidian
  • Bulk video support (playlists)
  • More languages

If you have ideas or run into issues, I'd love to hear from you.

If you find it useful, share it with someone who watches way too many YouTube tutorials. That's probably most of us.
