x.com with letxcook.com on any postEvery draft is scored against patterns learned from 1M+ real viral tweets. Ten signals reward momentum. Four catch risk.
letxcook checks your draft against concrete engagement signals, so every recommendation is explainable.
Recommendations are tied to the engagement behaviors your draft can encourage or reduce.
Drop your draft, thread or a screenshot of someone else's tweet you want to learn from. Multimodal in.
We score it across all 13 signals — 10 the ranker rewards, 4 it punishes — with the line that triggered each judgment.
Three rewrites, each strengthening a different weak signal. Copy the one that fits the angle you want.
Free is enough to try the signal map. Pro is for people who draft daily, compare angles, and want every post to leave the queue stronger.
Run every hook, rewrite, screenshot, and X URL through the 13-signal grader without waiting for next month's reset.
Tools in this category overpromise. We'd rather underclaim, show our reasoning, and let you decide.
Private by default. Anonymous drafts are not saved to an account. Signed-in users get audit history so they can revisit prior results, and can delete their account from settings.
Those tools often optimize against folklore: post-time charts, hashtag counts, link-in-comments tricks. We focus on engagement signals you can actually strengthen in the draft itself.
No, and anyone who promises that is lying. We grade the signals the ranker tries to predict — that's the direction. Audience fit, timing and luck are still real. We surface what you can control.
We do not claim access to X's production model or numeric weights. We work on direction — which engagement behaviors a draft is likely to encourage or discourage — not hidden ranking magnitude.
They're proprietary. We never guess at them. That's why every grade is a band (Weak/Moderate/Strong) instead of a percentage — we refuse to fake precision.
Not yet. letxcook is tuned for X drafts specifically. We'd rather be excellent on one platform than guess on five.
