Powerful analytics for X
A 300-follower account and a 300,000-follower account look identical on X until you open the profile. BoostX puts the numbers under the name — how big they are, how often they post, and how far the post actually travelled.
Colour tracks account size. Where there isn't enough data for a figure, nothing is shown — never a dash or a question mark.
Four numbers, under every name
Read from what X already renders on the page. Nothing is fetched on your behalf and nothing is requested from X's API.
- followers
- The count you'd otherwise open a profile to see. Coloured by size tier, so you can scan a screen instead of reading it.
- posts
- Lifetime post count, which tells you whether 40,000 followers took ten years or ten weeks.
- posts/day
- Original posts only — replies excluded. Measured across the posts actually seen rather than dividing a lifetime total by account age, which would answer a different question.
- reach
- How many times a post's views cover its author's following. Under 1× it stayed inside their own audience. Well above, X pushed it to people who don't follow them.
Reach, corrected for how old the post is
Raw views ÷ followers mostly measures a post's age, not how far it spread. A post twenty minutes old has barely any views yet; the same post two days later has all of them.
Across the posts collected so far, the median ran 0.019× under fifteen minutes and 2.93× past a day — a 150× spread with nothing about the actual travelling changed. BoostX divides by the share of views that have typically landed by that age, which flattens the age effect from 12.6× down to 1.3×.
So a twenty-minute-old post and a two-day-old post from the same account read about the same. That's the whole claim.
Set a size, and the timeline reorganises
Pick a follower threshold. Everything above it gets a highlight rail; everything below fades back, or disappears.
Dim and hide apply to the timeline only. They never touch a conversation you've opened.
What it doesn't do
- No sign-in. There is no account, and nothing to create.
- No access to your X account. It can't post, follow, like, or read your messages.
- Nothing that identifies you. Statistics about public posts are collected to compute posting rates and what a typical post does. No user id, no session id, no browsing history.
- Runs only on x.com. Every other site is untouched.
