FAQ

Common questions

What LinkedIn limit does this use?

It uses 3,000 characters as a practical planning limit for a post draft.

Do line breaks matter?

Yes. Line breaks make posts easier to scan, especially on mobile feeds.

Does the checker include hashtags?

Yes. Hashtags are part of the text and count toward the character total.

Do text tools publish final copy?

No. Treat generated or checked text as a draft. Review tone, factual accuracy, claims, brand voice, platform fit, and any legal or policy requirements.

Why should platform limits be rechecked?

Platforms can change limits, truncation behavior, display formats, and policy rules, so verify important posts in the publishing interface.
