Free tools

Free public tools you can use without logging in.

Keryo offers a set of free public tools — no account, no login required. They live on their own pages (available in English and French) and help with the little tasks every social media manager runs into.

The tools

Tool	What it does
Character counter	Count characters as you write, so you stay within each network's limits.
Engagement-rate calculator	Work out an engagement rate from your reach and interactions.
Instagram carousel splitter	Split a wide image into clean Instagram carousel slides.
Instagram grid maker	Plan how posts will line up on your Instagram profile grid.
LinkedIn text formatter	Add bold, italic and other styling to make LinkedIn posts stand out.
YouTube title checker	Check whether a YouTube title reads well and isn't cut off.

These tools are free and open to everyone — they don't need an active subscription or trial, unlike the main Keryo app.

When to use them

Reach for the free tools during everyday content work:

• Writing a post? Keep the character counter open.

• Reporting results? The engagement-rate calculator does the math for you.

• Prepping Instagram? The carousel splitter and grid maker save you a trip to a design app.

Inside the app, you'll find the same care for content in post templates and the AI assistant.
