the only twitter tool that reads x's algorithm

See what X.com hides from you.

X-Specter is the only Twitter intelligence suite that surfaces algorithmic flags, AI-generates replies in your voice, and maps your social graph — for less than BlackMagic's cheapest tier.

the problem

What X won't tell you.

Three things X.com knows about your account — and refuses to surface.

Shadowbans are silent.

X.com loads feature switches like shadowban_sensitivity and graduated_engagement into your browser on every page load. You just can't see them. Your reach drops 40% and nobody tells you why.

Follower churn is invisible.

You lose 3–8% of your followers every month. X.com shows you a count. It doesn't tell you who left, when, or — most importantly — what you tweeted that pushed them out the door.

Best-time-to-post is a guess.

You tweet at 9am because some blog post said so. X.com knows exactly when your followers are online and engaging — they just don't show you. You're flying blind on the most basic lever you have.

X-Specter reads what X doesn't show you.

X-Specter vs BlackMagic.so

BlackMagic is a good product. X-Specter is a different product. Here's the side-by-side.

Write a thread in your voice — in 4 seconds.

Paste a long-form thought. X-Specter splits it into a thread, in your tone, using your past 5 tweets as voice context. BlackMagic can't do this. Neither can Hypefury, TweetHunter, or Typefully.

What the first 200 builders say.

X-Specter is in private beta. These are from the first 200 installs.

I caught a graduated_engagement flag on my account that I'd been silently throttled by for three months. X-Specter showed it to me in 8 seconds. That alone was worth the install.

The network graph is what sold me. I found a cluster of 30 indie hackers in my followers I didn't know existed — they're now my most engaged audience. BlackMagic has nothing like this.

The AI thread builder actually sounds like me because it's reading my past tweets. I stopped using Typefully the day I installed X-Specter. Same for two other founders I told about it.

founders' note

Why we built X-Specter.

We got tired of Twitter tools that gate basic features behind $1,499/yr paywalls. We got tired of being shadowbanned with no way to know. We got tired of copy-pasting between five different tabs to write one thread that sounded like us.

So we built the tool we wanted. X-Specter is indie-owned, AI-native, and built by people who actually use Twitter for a living. No VC markup. No data harvesting. No bullshit. The free tier does more than competitors' paid tiers — because the basic stuff (CSV export, algorithmic flags, a network graph) should be free, and the genuinely valuable stuff (AI in your voice, multi-account, integrations) is what we charge for.
