Postneedle

Type any X handle. Five needles read its last 20 posts and score signal vs filler: AI-sounding, humblebrag, engagement bait, says nothing, buried point. Every post gets ranked, and there's a public leaderboard of the cleanest writers on X. Free to try. How it works: five yes/no needles read each post, one per failure mode. The account gets a 0-100 signal score, a one-line verdict, and a rank against every account read so far. You can also paste a draft before posting and watch the needles move while you write, or compare two accounts side by side. Every reading comes with a shareable card for X and LinkedIn. No sign-up needed.
