Common App Essay Review

Paste your draft. River reads it the way a reader on their fortieth essay of the day reads it, then leaves the comments in the margin — paragraph by paragraph, on your opening, your abstractions, your structure, and your voice. It does not rewrite a word of your essay.

  • 4 playbooks
  • 4 docs
  • 1 space rule
  • Free
  • Ten to twenty comment threads on a 650-word draft, each anchored to the paragraph the problem is in.
  • Every abstract claim — resilience, leadership, passion — checked against whether your essay actually shows it.
  • The review starts on its own the moment your workspace opens. No setup, no prompt to write.

Free account, then your space opens with the review already running. Your essay stays private and is not used to train models.

Or just set up the workspace — I'll paste later

A real capture. River reads the whole draft, then leaves comment threads on the paragraphs. Your prose is untouched unless you name a passage and ask for a rewrite.

How it works

  1. Paste the draft

    Straight out of Google Docs, or attach the file. A messy first draft is the useful case — a polished one has already lost the parts worth keeping.

  2. Make a free account

    It takes a moment, and it exists so the workspace is yours and stays private — not to gate the review.

  3. River runs the review skill

    Your space opens on the essay, paragraph for paragraph exactly as you wrote it, with ten to twenty comment threads landing on it and one memo on what to fix first.

College Application

This space is one good English teacher who has already read forty essays today and has nowhere else to be. It reads your Common App essay, comments in the margin paragraph by paragraph, and tells you the three changes that would help most. Then it does the same for every supplemental you write.

What it will not do is write your application for you. A review leaves comment threads on your paragraphs and leaves your prose alone — which is the whole design, not a limitation. The essay that gets read has to be yours, and readers can tell.

Getting started

Paste your draft in the box at the top of this page. The review is running by the time your workspace finishes opening.

If you would rather set the space up first, that works too — paste into the chat, or drag a file onto the desktop, whenever you are ready. Then, roughly in this order:

  1. Read the comments before you change anything. They come back worked through six dimensions: opening, show-versus-tell, whose essay this is, structure, voice, and economy. Reply to any of them the way you would reply to a teacher.
  2. Fill in your Applicant Snapshot. Activities, the moments you have considered writing about, and two or three sentences of your actual texting voice. It is what lets a comment say “the robotics story two paragraphs down would earn this claim” instead of “this is vague.”
  3. Run the Authenticity & Cliché Check once the structure is settled. It flags the lines another applicant could have written, and the lines only you could have.
  4. Bring your supplementals in as they come. Paste the school's exact prompt and word limit with the draft — a strong essay that does not answer the question asked is the most common way a supplemental fails.

What it checks

Every abstract virtue claim — resilience, leadership, passion, learning the value of hard work — against a concrete scene in your essay that would actually earn it, or a comment because none does. Openings that announce a theme instead of putting the reader somewhere. Paragraphs that could be reordered without loss. Endings that only restate the beginning. Thesaurus diction and résumé phrasing. Machine cadence: uniform paragraph lengths and metronomic rhythm. And your real word count against the 650-word limit.

What it will not do

  • Rewrite your essay because you asked for a review. Rewrites happen when you name the passage, and River tells you what it changed.
  • Invent biography. It will not suggest a hardship, a family member, or a motivation you did not write down. Where a paragraph needs material River does not have, it asks in a comment.
  • Attach a comment to an arbitrary phrase. Threads land on paragraphs, and they are comments — not tracked changes you accept or reject.
  • Predict an admissions decision or speak for any college. River has no relationship with the Common Application or any school.

Common questions

Is it cheating to have AI review my college essay?

Getting feedback on a draft is what every student with an attentive English teacher, a school counselor, or a $300-an-hour consultant already gets. Submitting writing that is not your own is the line — which is why River's review leaves comments instead of rewriting your draft. The feedback lands in the margin; the essay you submit is the one you typed. If you ask River to rewrite a specific sentence, it will, and it will tell you what it changed — but a review never does that on its own.

Will colleges be able to tell I used AI?

If AI wrote your essay, often yes — flattened rhythm, generic abstraction, and conclusions that only restate are exactly what a reader on their fortieth essay of the day notices, and AI-detection tools are unreliable in both directions. River is built for the opposite outcome. The Authenticity & Cliché Check flags lines that read as machine-written or borrowed, and calls out the lines that sound most like you so revision does not sand them off.

How does the inline commenting actually work?

Your draft becomes a River document. When the review runs, River reads the whole essay, then attaches comment threads to specific paragraphs — the same mechanism as a comment you would leave yourself. Commented passages highlight in the draft and each thread shows in a Comments panel beside it, attributed to River. You reply, resolve, or delete them. Your text is not modified.

What does the review actually look at?

Six things, paragraph by paragraph. The opening — does the first sentence put a reader somewhere specific, or announce a theme? Show versus tell — every abstract claim like resilience or leadership, checked against whether the essay dramatizes it anywhere. Whose essay this is — the sentences another applicant could sign without changing a word. Structure — movement from beginning to end, or a list of accomplishments in paragraph form. Voice — thesaurus diction, résumé phrasing, passive constructions hiding who did what. And economy — where the 650 words are actually going.

My essay is way over 650 words. Is it still worth reviewing?

That is the normal state of a real draft, and knowing which paragraph to cut is most of the work. River reports your true word count against the limit and its comments say where the essay is spending words on setup that delays the material worth reading.

Can I use it for supplemental essays too?

Yes. The same space has a Supplemental Essays document and a review playbook built for them, which reads against the school's actual prompt and word limit — a strong personal statement that does not answer the question asked is the most common way a supplemental fails.

What happens to my essay?

It goes into a private workspace on your account. It is not published, not shared, and not used to train models. You can delete the space at any time.

Do I have to pay?

No. You need a free account, and the review starts as soon as your space opens.

Find out what a reader actually thinks

Not whether it is “good.” Which paragraph is doing the work, which sentence any applicant could have written, and what to cut to get to 650.
