## 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

## Writefull

Writefull is a writing and proofreading tool designed for academics. Instead of relying on general-purpose language models, it uses models trained on millions of journal articles, so its feedback is tuned to the conventions, phrasing, and style of research writing. That calibration is why it tends to catch problems that generic proofreaders overlook, from awkward collocations to non-native phrasing that reads oddly in a paper.

The product lives where researchers already write. Writefull for Word delivers automatic language feedback inside Microsoft Word and can paraphrase, change style, explain, or summarize text. Writefull for Overleaf works within your LaTeX code and adds TeXGPT, which writes LaTeX for tables, formulas, and equations on demand. For pre-submission checks, Writefull Revise lets you upload a document, see its overall language quality, and fix errors with Track Changes. A set of AI widgets rounds things out: the Academizer turns informal sentences academic, the Paraphraser rewrites at three levels, and dedicated generators draft titles and abstracts based on your text or paper.

Writefull is used by students and researchers at more than 1,500 institutions and by major publishers and copyeditors, and it offers group and departmental licensing as well as premium access through institutional subscriptions. On privacy, the company states that texts and searches are processed over an encrypted connection and are never stored or used for training. It is available as a freemium product with paid and enterprise tiers.

**Pricing & Plans:** Writefull is sold as a freemium product: core features can be tried for free, while the full writing and proofreading toolkit requires a paid subscription. Institutional, group, and departmental licenses are available, along with premium access for universities and publishers and an enterprise offer. Exact pricing is provided on the vendor's site and via quote and may change.

- **Writefull for Word:** Get in-context language feedback automatically inside Microsoft Word, with options to paraphrase, change style, explain, or summarize text.
- **Writefull for Overleaf and TeXGPT:** Receive language feedback directly within your LaTeX code in Overleaf, generate LaTeX automatically, and use TeXGPT for tables, formulas, and equations.
- **Writefull Revise:** Upload a document before submission to see its overall language quality and apply corrections with Track Changes.
- **AI writing widgets:** Academizer turns informal sentences academic, the Paraphraser offers rewrites at three levels, and generators draft titles and abstracts from your text.
- **Citation support:** Writefull Cite helps you add and manage citations, rounding out a toolkit built for the academic publishing workflow.

**Strengths:** Language feedback specifically calibrated for academic writing; Integrates directly into Word and Overleaf workflows; Widgets for paraphrasing, academicizing, and generating titles and abstracts; TeXGPT automates LaTeX authoring for tables and equations

**Limitations:** Focused on academic English, so less suited to casual or marketing writing; Full premium features require a paid subscription or institutional access; Works best inside Word or Overleaf, so plain-text workflows are less covered; Non-English source support is limited compared to general proofreaders
