Step one
Crux read your account. Here is what it thinks you write about.
Confirm or correct this. Everything downstream — which openings surface, how crowding is measured — is scored against these topics, so it is worth thirty seconds.

Step two
Three rules, taken from your own best posts.
These are observations, not preferences we picked for you. Switch off any that read wrong and drafts will stop following them.
Open on a number
Thirty-one of your forty best posts start with a figure rather than a claim.
Yes: “My AI wrapper runs at 71% margin.” · No: “Let’s talk about margins.”
Keep sentences under fourteen words
Your median sentence runs nine words. Longer lines track with a sharp drop in replies on your account.
Top posts: 9 words median · Bottom posts: 21 words median
Never use hype words
Three phrases appear only in your worst-performing posts. Drafts get flagged before they reach the queue.

Step three
Set the ceiling on what X can charge you.
Crux samples your niche every fifteen minutes, and X bills per read. We pass that through at cost, so this cap is the only thing standing between you and a surprise.
Scanning pauses when the cap is reached and resumes on the 1st. You are never billed above it.
A typical Solo account spends about $0.84 a month, so $5.00 leaves plenty of headroom.
Not a login — you always sign in with X. This is how we send invoices, warn you at 80% of the cap, and reach you if you ever lose access to your X account.
