Does this predict whether a post will go viral?

No. It reviews the draft you provide for clarity, length, filler, and support. It does not have access to X's algorithm or your account analytics.

What stays in my browser?

The instant length and pattern checks run locally. If you request deeper draft notes, the text you submit is sent to the MarkdownMe AI service.

X/Twitter Post Critic

Run an instant browser-only preflight on a post, then request deeper AI draft notes about clarity, specificity, proof, and compression. It does not predict reach, score the algorithm, or promise virality.

The live preflight stays in your browser. It checks fit, links, hashtags, emoji, filler, and claims that may need support. Deeper AI draft notes are optional and never predict reach or virality.
