Anyone who has graded a full set of Heart of Darkness essays knows the same problems come up again and again. The thesis names a theme but makes no argument. The quotations are long, the commentary is short, and Kurtz gets called "evil" about forty times. A comment bank turns those patterns into a resource instead of a chore.

The best comment banks are organized by problem, not by grade. When you see that a paragraph retells the plot, you reach for the plot-summary family of comments and choose the one that fits. That is faster than scanning a list sorted by score, and it keeps the feedback tied to the actual writing.

Each comment should do three things: name what you see, explain why it matters, and suggest a next move. "This paragraph summarizes" only does the first. "This paragraph summarizes Marlow's arrival at the Central Station; what does the disorder there suggest about the Company's real priorities?" does all three.

Keep every comment short enough to fit beside the paragraph it addresses. A comment that takes a full minute to read will not get read. Students skim, so make the request obvious.

Comments for the most common problems

Below are five starting points, each written to be adapted rather than pasted unchanged. Adjust the details so the student can tell you read their paper. A comment that could apply to any essay teaches nothing.

• Thesis names a theme only: "Imperialism is a theme, but what is your argument about how Conrad presents it?"
• Plot summary in place of analysis: "You have told me what happens here. What does the way it is told reveal?"
• Quotation without commentary: "Good passage. Now explain which words carry your point and why."
• Author and narrator blurred: "Is this Conrad's view or Marlow's? The frame narrator makes that a real question."
• Overreaching claim: "Can one scene support a claim about the whole novella? Consider narrowing or adding a second example."

Adapting comments to the individual writer

A comment bank should never flatten the difference between a student who is close to a strong paper and one who is still finding a claim. For the first writer, a pointed question about Marlow's motives may be enough. For the second, you may need to model a stronger thesis sentence and ask them to try their own version.

Tone matters as well. Conrad's novella is difficult, and students already suspect they are missing something. Comments that start with what the paper does well before turning to what it needs tend to be read more carefully.

Where AI feedback fits into the bank

AI feedback tools can draw on a comment bank you already trust. GraideMind, for example, can generate draft comments aligned to your rubric so you begin from a specific note rather than a blank margin. You still read each one, and you replace anything that does not sound like you or does not fit the paper.

The gain is largely in consistency. A hundred essays with the same problem receive the same quality of explanation, whether they sit at the top of the stack or the bottom. That fairness is hard to maintain by hand.

Keeping the bank current

Revisit the bank after every unit. Add the new problems you saw, and retire comments that students consistently misread. A bank that grows with your classes becomes one of the most useful documents in your teaching files.

Share it with colleagues if you can. Two or three teachers contributing comments on the same novella will cover more ground than any one person, and students in different sections end up hearing similar guidance.
