MrBeast Retention & Virality Evaluator

Scores a piece of content (a video script, reels/shorts copy, opening paragraph, even a B2B presentation intro) from 0-10 in terms of MrBeast retention engineering. What's measured isn't style or quality; it's pure watch-through mechanics — the "doesn't lose you from the first second, constantly delivers curiosity + reward, everyone understands it" formula.

It examines content across 8 dimensions (M1-M8): cold-open hook, open-loop / curiosity gap, rising stakes, pacing / no dead moments, reward cadence, concreteness / numbers / visuals, re-hook, and simplicity. Each score is tied to an observation (quote + location) — no score is given without justification. The cold-open, open-loop, and pacing are weighted because they are the core of retention. A slow start, no stakes, a vague promise, dead moments, and a pile of jargon are penalized; a fake stake / clickbait-and-switch is flagged as an ethical downgrade.

When to use it: Before filming / publishing a video, to objectively check whether the opening "holds," to see the weak spots, and to know how to strengthen them.

Output: A total /10 + a one-sentence diagnosis, an M1-M8 score breakdown table (quote-justified), a concrete "MrBeast-ify" fix for the 2 weakest dimensions (which sentence is rewritten and how), and, on request, a machine-readable JSON score. It applies to B2B/deep content too.
