## AssignOwl

AssignOwl is built around a simple idea: students should find out what their grade will be before the deadline, not after. You upload your draft assignment along with the brief and marking rubric, and the platform reads it the way a strict examiner would, scoring every criterion in the marking scheme and explaining why each mark was given. It deliberately sets its pass bar higher than most human markers, so a positive verdict carries weight.

The output is a structured report rather than a chat response. You get a predicted grade and overall verdict, a breakdown of marks by section such as introduction, literature review, method, analysis and discussion, and line-level feedback that quotes your weakest sentences back with a note on what is wrong and how to repair it. Because the report is specific, it is designed to be actionable while there is still time left to revise.

Beyond grading, AssignOwl bundles related student utilities: an AI-detection preview that shows which passages a detector might flag, a topic generator for choosing research subjects, and a beta survey-filler for collecting research responses. It is marketed as a feedback tool rather than a ghostwriting service, and states that it never writes your assignment for you. Pricing is credit-based and pay-as-you-go, so there is no subscription to cancel between terms.

**Pricing & Plans:** Pay per assignment with credits, no subscription. The Starter pack is a one-off $5 for 40 credits (2 gradings) and the best-value pack is a one-off $20 for 260 credits (about 13 gradings). Each grading consumes 20 credits and includes the full report.

- **Rubric-matched grading:** Every criterion in your marking scheme receives its own score and a written reason, so the feedback maps directly onto how your work will actually be assessed.
- **Predicted grade and verdict:** A single headline grade such as 72% or 'Pass, 2:1' plus a section-by-section mark breakdown across argument, evidence, analysis and referencing.
- **Sentence-level line feedback:** Weak lines are quoted back to you with what is wrong and a concrete suggestion for fixing them, making revision faster and more targeted.
- **AI-detection preview:** See which passages an AI detector is likely to flag before your university runs its own check.
- **Shareable PDF report:** Download your report as a PDF or share a verification link that anyone, including an institution, can use to confirm the report is genuine.

**Strengths:** Marks to your own rubric rather than giving generic writing advice; Report is specific: predicted grade, per-section marks and quoted problem sentences; Deliberately strict, so a pass verdict is reassuring rather than flattering; Credit packs are pay-as-you-go with no subscription commitment

**Limitations:** Costs a credit fee every time you re-grade a revised draft; Focus is on university-level written assignments, so it is not a general writing assistant; Some features such as survey filling are still labelled beta

## Scribbr

Scribbr was built around a simple promise: help students submit work they feel confident about. The core of the service is human proofreading and editing, delivered by a hand-picked pool of academic editors who go through an in-house training programme before they are allowed to take orders. Documents are returned with tracked changes, in-text comments and a short personal letter explaining the reasoning behind the main edits.

Alongside the human service, Scribbr offers a growing library of AI writing tools. The Academic Check bundles together grammar and language review, citation checking, plagiarism scanning and AI-content detection into a single upload, which is convenient when you want one pass over an entire paper rather than juggling separate tools. Individual utilities such as the citation generator for APA, MLA, Chicago, AMA, IEEE and ACS, the paraphrasing tool and the text summarizer can be used on their own without paying for an edit.

The platform also maintains a large free knowledge base of academic writing guides that has become one of the more popular ways students discover the brand. Pricing depends heavily on document length, chosen turnaround time and add-on checks, so the practical way to get a number is to upload a file and select services in the order flow.

**Pricing & Plans:** Freemium model. Free tools include the citation generator, grammar checker and summarizer. Human proofreading and editing, the plagiarism checker, AI detector, AI proofreader and Academic Check are paid per document, with the final price depending on page count, delivery speed and any add-on checks such as structure or clarity review.

- **Human proofreading and editing:** A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
- **Plagiarism checker:** Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
- **AI detector and AI humanizer:** Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
- **Citation generator:** Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
- **Academic Check bundle:** Runs grammar, citations, clarity, plagiarism and AI-detection checks in a single upload of the whole document.

**Strengths:** Combines human editors with AI tools rather than relying on one alone; Strong editorial vetting process and a large pool of academic specialists; Free citation generator and knowledge base are genuinely useful on their own; Transparent turnaround options starting from a few hours

**Limitations:** Paid services are priced per document, which adds up for long theses; AI detector verdicts can still be disputed by institutions; Some premium checks require you to buy them alongside an editing order
