The X Algorithm
Edition II
Follow ✓
Follow ✓ is a free Chrome browser extension for X. It finds accounts that don’t follow you back and puts them in chronological order, from earliest followed to most recent.
Switch between Blue checks and Everyone else, then unfollow accounts with ease. One click on the red button unfollows that account. You choose who stays.
- Open the blue person icon in Chrome or on X.
- See your totals in the Your numbers tab.
- Scan again or export your lists as a CSV.
Custom-built for The X Algorithm book and included with your book purchase. There is no separate charge for Follow ✓. Your lists stay in your browser, and you choose which accounts to unfollow.
Post lab
Post lab turns the book’s guidance into examples you can explore. Compare weaker and stronger posts across six subjects, with an explanation of what changed and why.
Follow the example reply thread, explore the published weights, or enter a draft in the checker to review it against the book’s writing guidance.
- Side-by-side examples with clear explanations.
- A place to practice before you publish.
- A weights reference tied to your edition.
Examples are fictional. The checker does not publish to X or predict your reach.
