Frequently asked questions
Are these X and LinkedIn tools free?
Yes. Every tool on this page is free. The utilities run entirely in your browser, and the AI writing tools include 5 free generations per day with no account required.
Do I need to log in or connect an account?
No. Nothing here requires a login or a connected profile. You only sign up for Xpert if you want drafts in your own voice, scheduling, and analytics on top.
How do the AI writing tools work?
You type a topic and the AI writes tweets, hooks, threads, replies, or LinkedIn posts for you. The prompts are tuned against generic AI output: no hashtag spam, no buzzwords, concrete and punchy drafts you can edit and post.
Which tool should I start with?
If you want to post more on X, start with the AI tweet generator or the thread generator. For LinkedIn, the headline generator and post generator fix the two things most profiles get wrong.
How many characters can a post have?
A standard X post is 280 characters (25,000 for Premium). A LinkedIn post can run to 3,000 characters, a LinkedIn headline to 220. The character counters track all of these limits live.
