Bangermeter — X Algorithm Scorer

Scores posts with X's published For You ranking weights and the real scorer arithmetic. Every factor cited to source.

See what X's algorithm actually rewards — on every post, as you scroll. HOW TO USE IT 1. Scroll x.com. Every post picks up a badge with two scores, 0–100. 50 is a typical post. 2. Click the badge. You get a plain-English breakdown of why it scored that way. 3. Start typing a post. A live meter scores your draft before you send it. That is the whole thing. Everything below is why you can trust the numbers. WHERE THE NUMBERS COME FROM On August 13, 2026, X published the real ranking weights for the For You timeline: the exact numbers that decide how far a post travels. Bangermeter puts them on every post in your feed. No leaked screenshots. No "I reverse-engineered the algorithm" threads. The weights come straight from X's published source, and every factor in the breakdown is cited to the line of code it came from. WHAT YOU GET • A score badge on every post as you scroll. Two numbers, 0–100, where 50 is a typical post. – Content Appeal: what the ranking signals would predict from the content alone. – Earned Engagement: how the weights value what the post actually earned, per view. • Click the badge for a plain-English breakdown. Which signals fired and why, what each reply and repost is actually worth, the rescoring factors that applied, and how fresh the post is. Every section has a "Show the math" expander with the full weight × probability table if you want the numbers. • A live meter in the compose box. Score your draft as you type, with hints as they trigger — asks a question, substantive text, bare link, hashtag pile, engagement bait. • A weight table in the popup. All 26 ranking heads, their published values, and which ones the extension can measure versus estimate. • Reply mode. Reply drafts are scored as replies (they take a ×0.75 factor in the published math), and the breakdown explains what X publishes about replies: out-of-network replies never reach For You at all, replies never get the mutual-follow boost, and replies to accounts over 100K followers are quality-scored by a Grok model whose rubric X withholds. • Draft comparison. Save up to three variants of a draft and pick the best-scoring one before posting. Variants live in memory only. • Local score history. Opt in from the popup and opening a breakdown logs the scores, the post's link and a short text snippet to a list in your browser, so you can see which formats score higher over time. Off by default, capped, local-only, one-click clear. • Under the Hood import. In X's transparency pilot? Import the report you download from x.com/i/under_the_hood and see the visibility labels X itself applied — parsed locally, stored locally. • A posting-cadence note. Post twice into the same stretch of feed and the panel shows the author-diversity attenuation production applies (second post ×0.625, decaying to a ×0.25 floor). SOME OF WHAT THE WEIGHTS SAY • Copying a post's link carries 20, the heaviest positive coefficient X publishes. It is also one of the rarest actions a reader takes, which is part of why the number is so large. • A reply carries 5. From someone you mutually follow, on an original post, 20. • Sharing to DMs carries 5, and nothing in the visible counts shows you it happened. • Profile clicks are worth nothing. That head used to pay, and X zeroed it. • Muting hurts nearly twice as much as blocking. • Scrolling straight past is a scored penalty. • Bookmarks are not a scored action at all. • Links do get credit. The "link penalty" was always folklore. HOW IT'S HONEST ABOUT WHAT IT KNOWS The weights are X's. The probabilities are estimates. X predicts how likely you are to reply, share or mute a post using a model nobody outside the company has. Bangermeter derives three of those probabilities from real counts — likes, replies and reposts — and estimates the rest from what's in the post. Every head in the popup is labeled as measured, estimated, or zeroed by X, so you always know which is which. It also matters that these weights multiply a predicted probability, not a count. A report is not a 234-point deduction; that number is the coefficient on how likely a viewer is to report you. Anything claiming these are per-action point totals has it wrong. There are no invented numbers anywhere in this extension. Circulating figures that failed source-tracing — "bookmark 20x", "links minus 30-50%", "block minus 120" — were left out rather than guessed at, and none of them matched the real values when those were published. This is a relative score against a typical post. It is not a prediction of reach, and nothing can honestly promise you one. PRIVACY • No data collection. None. • No network requests. The extension never phones home, because there is no home. • No account, no sign-in, no analytics, no tracking. • The only permission is storage: your settings sync with your Chrome profile, and the optional score history and imported Under the Hood report stay in this browser's local storage. Nothing is transmitted anywhere, and both are one click to delete. Everything runs locally in your browser. The source is public and reviewable. OPEN SOURCE MIT licensed, with the full research record and 228 automated tests that check every published weight against X's source individually. github.com/itsryanlenk/bangermeter WHAT'S NEW IN 0.10.1 • A quick start, on install. Installing now opens a short page that shows what the badge looks like, what the two numbers mean, and the three things you do with it. It lives in the extension — no network request, nothing loaded from anywhere — and the popup keeps a link back to it. The first outside feedback this project got was that a new user could not tell quickly what it was for; that was fair, and this is the fix.
