Summary

Allie K. Miller interviews Greg Brockman, president and co-founder of OpenAI, about how the best engineers and leaders work in the age of AI. Brockman shares his personal workflow of constant context switching, examples of vibe coding with Codex, and how small AI-driven friction removals compound into productivity gains. He advises founders to build now and focus on vertical AI with deep domain expertise, discusses proactive agents like ChatGPT Pulse, and closes with the message that AI adoption will soon be as essential as computers, with competitive advantage coming from domain knowledge and human relationships.

About this tool

Paste a YouTube link and get the gist without watching: a few sentences on what the video covers, the key points, chapters with timestamps and study notes — all written from the video's own words, with the full transcript a click away to check them.

How it works

  1. Copy the video's link.
  2. Paste it into the box and press Transcribe.
  3. Read the summary, key points, chapters and notes; open the transcript to check any detail.

What you get

  • A short summary of what the video says
  • Key points and chapters with timestamps
  • Study notes you can download as Markdown
  • The full transcript underneath

What it will not do

  • Audio that has to be transcribed is capped at 90 minutes. Videos with captions can run longer.
  • One video or episode per link for free. Whole YouTube playlists are a paid workspace feature; channels and live streams are not supported.
  • Private, members-only and age-restricted videos cannot be fetched.
  • Free transcripts are timestamped paragraphs. Speaker labels (who said what) are a paid workspace feature.

Questions

How is the summary made?

The video is transcribed first, from its captions or its audio. An AI model then writes the summary, key points, chapters and notes from that transcript only, without adding facts of its own.

Can I summarize long videos?

Videos with captions can be several hours long. Videos without captions are transcribed from the audio, up to 90 minutes.

What if the video or episode has no captions?

We transcribe the audio. A video with captions takes seconds; without them, its audio is transcribed with Whisper, which takes about a minute for every 15 to 20 minutes, up to 90 minutes for free. Podcast episodes are always transcribed from their audio.

Is it really free?

Free to start, with no card. A free account comes with 30 AI credits, and 30 more every month: enough for about 10 videos with captions, or 2.5 hours of Apple Podcasts or Spotify audio, as public transcripts. Reading transcript pages is free for everyone. For more, Blumify Unlimited (US$9.99 a month, or US$59.99 a year) covers transcripts, notes, questions and translations without counting credits: videos with captions without a limit, and 50 hours of audio a month at full speed, then up to 1 hour a day.

Who can see my transcript?

Transcripts made from a link here are public: each gets a page with its summary and notes, so a link someone else already transcribed opens instantly, free. To keep a transcript to yourself, make it in your private workspace instead (it uses the same AI credits).

How accurate is it?

We measured it on podcasts, talks and earnings calls with human transcripts: transcripts on our standard speech model were 87.5% accurate, and the most accurate model we tested reached 90.1% (with bought credits or Unlimited, you can choose it for a private transcript). Videos with captions use them, and YouTube's automatic captions were 94.3% accurate. Full results: blumify.io/accuracy. The summary and notes are written by AI from the transcript, so check anything important against the recording.
