Highlighter carousel generator

A highlighter carousel marks the line that matters on each slide and leaves the rest pale. It borrows the way people read a book they care about, and it tells the reader exactly where to look before they have read a word.

5 slides is over the limit on Bluesky (4) and X (Twitter) (4). Those posts get rejected rather than trimmed, so hide or remove some, or split the carousel across more than one post.

This carousel lives in this browser. An account keeps it.

Everything you have typed here is stored on this device only, so it is gone the moment you clear your browser or switch to your phone. With a PublishQ account it belongs to you instead:

  • Your carousels are saved, so you can come back and edit them.
  • The images you upload stay in your media library.
  • Your logo is stored once and reused on every carousel.
  • Brand name, handle, and colours stop being retyped.
  • Publish straight to every social account you connect — no downloading, no second tab.

A marked line is an instruction to read it

Attention on a phone lasts about as long as it takes to decide whether a slide is worth reading. A highlighted line removes that decision, because the eye goes to the marked words automatically.

Leaving the surrounding text pale is what makes it work. Contrast is the whole mechanic, so a slide where everything is emphasised is a slide where nothing is.

Quotes, notes and takeaways

Book notes are the natural fit: the sentence you underlined plus your own reaction underneath. Client quotes, review lines and interview answers work the same way.

Attribute quotes on the same slide as the words. A quote whose author appears two slides later gets screenshotted without them, and then it circulates as yours.

Before you export

  • Highlight one line per slide. Two marked lines cancel each other out.
  • Put your reaction under the quote rather than inside it.
  • Attribute a quote on the slide that shows it.
  • Keep highlighted lines short enough to read without wrapping twice.

This tool is free, forever. No accounts, no paywalls, no catch.

I build these solo. If you want to support my work, donating a coffee would be highly appreciated! ☕

Frequently Asked Questions

Everything you need to know about Highlighter carousel generator from PublishQ

A carousel where one line on each slide carries a marker sweep and the rest of the text stays pale, directing the reader to the important sentence.
Quotes, book notes, review lines and single takeaways. Anything where one sentence is the content and the rest is context.
You can, but it weakens the effect. The layout relies on contrast, so a single marked line reads far more strongly.
Whatever your accent is, as long as the text stays legible through it. Yellow and lime read most like a real marker, and darker colours need lighter text.
No. Exports are free, full resolution, watermark free and need no account.

— me 👋

Hi, I'm Alexandro 👋

I left my Software Engineer role at Amazon to build tools that solve real problems — the kind big companies ignore because they read spreadsheets instead of using their own products.

I was spending over an hour daily just scheduling 2 shorts across 3 platforms — logging in, reformatting, uploading one by one. That felt broken. So I built PublishQPublishQ . Now I create 4 shorts in 3 minutes and schedule them to 4 platforms in under 30 seconds.

PublishQ is bootstrapped. No investors, no vanity metrics. I build what actually helps you — because I use it every day myself.

Thank you,

Alexandro
