Private writing tool
Check the form. Keep the poem yours.
Test line count, haiku syllables, sonnet length, limerick rhyme, acrostic initials, and common rhyme patterns before asking a model for help. The check runs locally and marks pronunciation uncertainty instead of pretending meter is exact.
Local check: this poem stays in your browser and is not sent to a model.
What it can verify
Deterministic rules catch the easy misses: wrong line counts, broken acrostic initials, approximate 5–7–5 shape, repeated end-rhyme groups, and the long/short profile of a limerick.
What still needs you
A dictionary cannot hear every dialect, intentional elision, performance choice, or expressive variation. Read the draft aloud, then use the report as evidence—not a verdict.
