Headline A/B compare

# Two to four headlines, side by side

Write the versions you can't choose between. The table lines up the facts, from length to capitalization, and leaves the verdict to you, or better, to your readers.

## Reading the comparison

Paste the versions you are torn between, up to four. Every row is a plain fact about the words, worked out in your browser as you type.

- **Characters, words and width** show which version is longer and whether it would fit a desktop search result; the width uses the same method as the [length checker](https://amberheadline.buzz/headline-length-checker/).
- **Numbers** lists digits and number words, and notes when a number leads the headline.
- **Question mark, subtitle, brackets and “you”** show the shape of each line at a glance.
- **Capitalization** names the style a headline follows. “Mixed” means it matches none, and lists the words to change for the nearest one; the [title case converter](https://amberheadline.buzz/) fixes them all at once.

### Why there is no score

No formula knows your readers. A tool that crowns a winner is guessing, and different audiences reward different things. The honest test is a real one: send two subject lines to halves of your list, or try two titles on the same post, and keep the one people choose.

## Questions

**Which headline should I pick?**

The one that is clearest about what the reader gets. Use the table to catch problems, such as a title too wide for search or inconsistent capitals, then test the finalists with real readers if you can.

**Are my headlines saved?**

No. Nothing you type is stored or sent anywhere. To keep a comparison, copy it as a Markdown table or download it as a CSV file.

**What counts as a number?**

Anything written in digits, plus number words such as seven, dozen or first. “Leads” means the headline starts with it, as in list articles.
