Shakespearean Sonnet

Shall I compare thee to a summer's day?
Thou art more lovely and more temperate:
Rough winds do shake the darling buds of May,
And summer's lease hath all too short a date.

What you get
Beyond text generation.
Annotated
Form-rules checklist
Every poem is checked against the form's rules — line count, rhyme scheme, syllable pattern. You see what landed and what bent.
Color-coded
Rhyme-scheme overlay
End-rhymes are colored by group. ABAB CDCD EFEF GG isn't an abstract pattern — it's a visual map across the page.
Portable
Print-ready PDF
One click for a clean, distraction-free PDF. Standard literary spacing, proper margins. Take it to a workshop or save it.
Most language models, asked for a sonnet, will give you fourteen lines that rhyme roughly and scan barely. They reach for clever-sounding words that fail the actual metrical check — the kind of poem that looks right at a glance and falls apart when you count syllables.
We try harder. Every output goes through a deterministic check after generation: line count, rhyme scheme, syllable count per line. The annotations you see beside the poem aren't generated by the model — they're computed from its output, against the form's rules, with no AI involved.

That's the differentiator. Other generators give you a poem and ask you to trust it. We give you a poem and show you the receipts — every rule, checked, color-coded, and yours to keep.
