How our tools and content work

We build tools you can check. This page explains what happens when you use them, where our numbers come from, and how we test a change before it goes live. If something here does not match what you see, tell us and we will fix it.

What happens when you use a tool

Most tools run entirely in your browser. The Text Formatter, Bold Text Generator, Character Counter, Post Preview, Banner Maker, Carousel Generator, Profile Photo Resizer, QR Code Generator, the calculators and the message composers never send your text or images anywhere. You can turn off your internet connection after the page loads and they keep working.

The writing tools are different. The Headline Generator, Hook Generator, Post Generator, Comment Generator, About Generator, Recommendation Writer and the Cold Message and InMail Generator send the details you type to an AI model so it can draft suggestions. We send only what you entered in the form, we do not store it, and we do not use it to train anything. The full details are in our AI disclosure.

Every AI tool asks for your own facts: your role, your result, your audience. It is set up to work with what you give it and not to invent numbers, employers or achievements. If a draft contains something that is not true for you, change it before you post.

If the AI cannot answer right away, the tool still gives you suggestions built from our own tested patterns, so you are never left with an empty screen.

Where our numbers come from

Every character limit and image size our tools use lives in one table: the LinkedIn limits page. Each tool reads from that table, so when LinkedIn changes a limit we update it in one place and every counter follows. The table shows the date we last checked each value against LinkedIn’s own help pages.

We do not publish engagement benchmarks, response rates or “best time” claims we cannot back up. Where a guide talks about what is “good”, it shows you how to measure your own baseline instead. When we have our own data, we will publish it with the method behind it.

How we count characters

LinkedIn limits are counted in characters, but characters are not as simple as they look. Bold and italic text from the formatter uses special Unicode letters that a computer stores as two units each, and some emoji are built from several characters joined together. Our counters count each Unicode character once, so a bold letter counts as one and a simple emoji counts as one, while a combined emoji such as a family or a flag counts as more. LinkedIn may count some of these differently, so if you are right at the limit, leave a small buffer.

How templates and examples are written

Every template and example on the site is written by our team for that page. None are copied from real people’s posts or profiles. Names and companies in examples (Dana, Morgan, Northwind, Lumen Health) are made up, and numbers inside an example are there to show the shape of a good line, not to describe anyone’s real results.

Templates mark the parts you should replace in curly braces, like a first name or a company. We check that no template goes over its LinkedIn limit once the blanks are filled with typical details.

Ratings

The star rating on a tool page shows only real ratings from visitors, averaged. We show nothing until at least one person has rated a tool, and we never seed ratings or reviews.

What we test before a release

Every change goes through the same checks before it reaches the live site:

• Each tool, in a real browser. We open every tool, fill it in, and check the result, the copy buttons and the character counts.
• Accessibility. Pages are scanned in light and dark mode against WCAG 2 AA, and controls are checked for keyboard use, labels and 44 pixel touch targets.
• Speed. Pages are measured with Lighthouse on every change.
• Links and pages. Every internal link must point to a page that exists, and every page needs a clear title, description and heading.
• Privacy. We check that no key or secret can end up in a page you download.

How we keep content current

Guides and tool pages show the date they were last updated. We review them when LinkedIn changes a feature or a limit, and when a reader points out something that no longer works. Our editorial policy explains how we write and correct guides, and the changelog lists what changed and when.
