Turn a Hacker News post into a vertical video

Paste an item link and get a clean MP4 of the story or the comment typing itself out, with the points and the comment count on the card.

Works with links like news.ycombinator.com/item?id=8863. The same form covers stories, Ask HN posts and single comments.

How it works

  1. 1

    Paste the link

    Drop in any item link. reyoy reads it from the public Firebase API and fills in the username, title, body, points and date. Hacker News has no avatars, so the card uses an initial.

  2. 2

    Pick a look

    Choose a format, a background and a typing speed. The preview updates as you go, so there are no surprises in the file.

  3. 3

    Download the MP4

    Your browser encodes the video on your own machine and hands you the file. No upload, no queue, no watermark from us.

Questions

Is it free?

Yes. reyoy is free to use and there is no account. The site carries ads to cover hosting.

Does this need an API key or a login?

No. The Hacker News Firebase API is fully open, with no key and no rate limit worth worrying about. Nothing you paste is stored.

Which browsers can export?

Export needs the WebCodecs video encoder, which means a recent Chrome or Edge on desktop. The preview works everywhere. If your browser cannot encode, the download button will tell you.

Why did my link fail?

Deleted and dead items cannot be read, and a link submission with no text types its title out instead. Open "Write it yourself" if you would rather type it in.

What is the "Recreated" mark?

Anything typed in by hand carries a small Recreated label beside the date and a quiet mark in the corner of the video, and it never gets a verified tick. That keeps manual mode useful for your own drafts and for parody while making it clear the card is not a screenshot of a real post. Posts loaded from a real link render clean.

Can I use any post?

Only if you have the right to. Use your own posts, or get permission from whoever wrote the one you want. Never pass a post you typed yourself off as someone else's real one. You are responsible for what you make and where you post it.

What sizes can I export?

9:16 at 1080 x 1920, 1:1 at 1080 x 1080, 16:9 at 1920 x 1080 and 4:5 at 1080 x 1350. All at 30 frames per second, H.264, no audio track.

Is reyoy connected to Hacker News?

No. reyoy is an independent tool and is not affiliated with, endorsed by or sponsored by Y Combinator. Every name and logo belongs to its owner.
