LumiSource is a platform for students applying to college that also sells AP and SAT prep. Its essay review scores a draft out of 100 with category scores and a list of things to fix, and it keeps your college list, deadlines and supplements in one place.

Is LumiSource or NudgeEssay cheaper?

It depends on how you work. For many drafts in one month, LumiSource: $49 covers unlimited reviews. NudgeEssay is $25 for one essay, $150 for 10 or $200 for 20, and each essay includes one free re-read of the revised draft. It is paid once, and nothing renews or expires.

Does either one write my essay?

LumiSource’s pricing and home pages do not say either way, so ask them. NudgeEssay never hands you a sentence you could paste into your draft: it points at what you wrote and tells you what to change. Every college sets its own rule on AI, and checking your school’s policy is on you.

Can I try NudgeEssay free?

Yes. Paste your essay and you see the verdict, the standout line and the six rubric bands before any payment step. Seven complete sample reports are also published in full, free to read with no account.

Is NudgeEssay affiliated with LumiSource?

No. NudgeEssay is not affiliated with, endorsed by or partnered with LumiSource, and has no relationship with any college. Every LumiSource fact on this page was read from their own site on 10 October 2026 and is linked below with that date. LumiSource is a trademark of its owner.

A LumiSource alternative, for when you would rather pay per essay than per month

LumiSource is a platform for students applying to college that also sells AP and SAT prep. Its pricing page lists two plans: a free one with one essay review, and Premium at $49 a month for unlimited essay reviews and re-checks, cancel anytime. Its homepage shows an essay scored out of 100 with category scores and a list of things to fix, next to a tracker for your college list, deadlines and supplements.

NudgeEssay is priced per essay, not per month: $25 for one essay, $150 for 10, or $200 for 20, about $10 an essay. What comes back in about five minutes is a document: the one sentence a tired reader would carry out of your essay, six rubric bands built for that essay type, notes attached to your exact sentences, a paragraph-by-paragraph map of where attention drops, and a revision plan ranked by payoff. Every essay includes one free re-read of the revised draft, and nothing renews or expires. You see the verdict and the bands on your own essay before you pay anything.

The short version: if you will revise many drafts in one month, or want test prep and application tracking in the same place, LumiSource costs less for that, and that is worth knowing. If you have a set number of essays and want each one taken apart closely, then read again once you have revised it, a pack is paid once and does not run on a clock.

When LumiSource is the better buy

If you plan to run many drafts through a reader inside one month, a flat monthly plan is the cheaper way to do it: $49 covers unlimited reviews and re-checks. And if you also want AP or SAT prep, or one place to track your college list, deadlines and supplements, LumiSource sells those and NudgeEssay does not.

When a per-essay read is the better buy

If you have a known number of essays, say a personal statement and a handful of supplements, and you want each one taken apart closely, revised, and then read again, a pack costs the same whether you finish in a week or in January. Nothing renews if you forget to cancel. And if you want a person as well, the expert-read plans put a written human read on top of the same report.

All 23 checks are listed on what the review includes, and seven complete unedited reports are free to read on the samples page. Read one before deciding whether this is worth paying for. If the other options on your list are AI reviewers too, the Kolly comparison sets a plan that renews beside a per-essay read, and the GradGPT comparison does the same for a season pass.

What NudgeEssay is not

It is not an admissions decision, a prediction or a chance calculator, and it has no relationship with any college.
It is not a school list, a test-prep course or an application strategy. It reads one essay at a time.
It will not write your essay, and it should not. Every college sets its own rule on AI, and checking your school’s policy is on you.
