Full grammar checkers want your text on their servers and a subscription for the privilege. GramMachine does one narrower job, for free, entirely in your browser: it flags the patterns that make writing harder to read.
Passive voice, run-on sentences, filler words, and a plain-English reading-ease score -- the same checks a good editor runs by eye, done instantly on your draft.
Nothing you paste is uploaded, logged or stored. Close the tab and it's gone.
We publish only what we can stand behind: figures are labeled indicative when they move fast, comparisons state their criteria, and affiliate relationships never decide a verdict. Corrections: idocanfi@gmail.com.
