Type any X handle. Five needles read its last 20 posts for AI-sounding lines, humblebrag, engagement bait, saying nothing and buried points. You get a score out of 100, a one-line verdict, every post ranked, and a card to share. There's a public leaderboard, a side-by-side duel for any two accounts, and a draft checker that reads a post before you publish it. Free, no sign-up.
Hi Product Hunt, I'm Alejandro. I built Postneedle because my own posts had started to read like filler and I wanted something that would tell me so without being polite about it.
How it works: five narrow yes/no questions read each post, and each one answers with a probability instead of text (it runs on Jev, TypeSafe's System One, so there's no text-generating model anywhere). Five narrow questions agreed with themselves far more than one big "is this slop?" question did.
So far it has read 53 accounts. Paul Graham and Ben Thompson lead at 76. Elon Musk (70) writes cleaner than James Clear (58): the advice accounts lose on "says nothing". Two builders with small followings are in the top ten, above most of the famous names.
The verdicts are the part people react to. Mine: "Writes like it is being audited. Read by about as many people." Type your handle and tell me if yours is fair.
