October Field

A working draft, checked by the editor

The fence leans where the summer left it, the grass gone brittle, gold and dry, I walk the rows that we once planted and watch the geese unzip the sky. The house still holds your coat and thimble, the kettle keeps its patient steam, and every window frames the winter that walks toward us through the trees.A sample draft, shown with its full editor's report.
Grammar & spelling
Clean copy. One deliberate compression worth keeping: "the grass gone brittle" (line 2) rides on an implied has — it reads as voice, not error.
Rhyme strength
Stanza 1 lands a true rhyme (dry / sky). Stanza 2 softens to a slant pair (steam / trees) — if the drift is deliberate, keep it; if you want stanza 1's click, the closing word has to do two things at once: hold the kitchen image and land a fuller vowel.
Meter & rhythm
Loose tetrameter throughout, comfortably conversational. Line 5 runs a foot long ("The house still holds your coat and thimble") — dropping still restores the pulse without losing the sense.
Weakest line
Line 8: "that walks toward us through the trees"walks doubles line 3's walk and flattens the image. The verb is the one place this line can still surprise: what is the winter's approach actually like underfoot — heavy, slow, resisted?
What's working
"watch the geese unzip the sky" is the draft's best verb — concrete, kinetic, earned. And the domestic inventory (coat, thimble, kettle) builds the elegy without once naming grief. Protect both in revision.

A representative report. Your own run reads your actual line breaks and references them by number — paste a draft above to get the same treatment.

How it works

  1. Paste your draft

    Keep your line breaks — the editor references issues by line number.

  2. Sonnet 4.6 reviews it

    A poetry-editor prompt + structured schema returns six categories of feedback.

  3. Fix and re-check

    Each check is saved to a permanent URL. Iterate without losing prior notes.

Writer questions

Frequently asked

How is this different from the Poem Analyzer?

The Analyzer explains what a poem means — themes, symbols, line-by-line gloss. The Checker reviews your draft for fixable craft issues — grammar, spelling, weak rhymes, slack lines. Use Analyzer to understand someone else's poem, Checker to polish your own.

Does it understand free verse?

Yes. The checker only flags rhyme or meter patterns the poem is already attempting — it won't demand rhyme in free verse or scold you for varying meter on purpose.

Does it edit my poem or only flag issues?

It flags and directs. For every weak line you get why it isn't working and a concrete direction to take it — an angle, a question, a constraint to write into. What it won't do is hand you the replacement line. The rewrite is yours, which is the whole point of having one.

Is it really free?

Yes, to try — one free run with no signup, and one more with a free account, shared across all Storgy AI tools (Analyzer + Checker). The free runs are one-time, not daily. After that, plans start at $9/month for 100 credits (most runs cost 1 credit). The pure-compute tools — Syllable Counter, Rhyme Scheme Finder, Citation Generator, and the rest — stay free and unlimited.

Which AI model powers it?

Claude Sonnet 4.6, called with a strict structured-output schema so the editor notes always come back in the same shape.

Is my draft private?

Each check lives at a URL with an unguessable short ID, but it's publicly reachable. Don't paste anything you wouldn't want a stranger to see.

Will it tell me if my poem is good?

No — the Checker is a line editor, not a judge. It finds fixable problems in your draft and tells you what to do about the ones you can fix; it does not score the poem. Scoring is a separate tool, the Poem Rater.

What if it's wrong?

AI feedback is a starting point, not a verdict. If a flagged issue contradicts your intent, ignore it. Trust your ear and your reader.

Can I argue with one of the notes?

You can argue with a note, yes — on runs made while you were signed in. Under the result there's a conversation with the reader who flagged the issues. Ask why a line is marked weak. Ask whether an issue really applies to what you were doing; sometimes the honest answer is that it doesn't, and that's the answer you'll get. It's given your poem and the notes on the page to work from, and it's instructed never to hand you a replacement line. Each message costs 1 credit. The recorded check and its link don't change.
