## Isgen AI Detector

Isgen positions itself as a high-accuracy AI checker for teachers, students, editors and content teams. You paste or upload text, optionally in bulk, and the detector first scores the document as a whole before running a second pass that classifies individual sentences as Human, AI or Mixed. Results are shown with color-coded highlighting and an AI impact score list, so you can jump straight to the passages most responsible for a high AI reading.

Beyond raw detection, Isgen wraps a wider writing-integrity toolset around the core engine: a plagiarism checker, an AI grammar checker and proofreader, a humanizer, a presentation maker and an AI Editor that shows your AI score while you draft. The editor is designed to remove the usual copy-paste loop between a word processor, a detector and a rewriting tool.

The product follows a freemium model with a free entry point and paid tiers. Public pricing shows an Academic plan around $8 per month, a Writing plan around $15 per month and an Ultimate plan around $24 per month when billed annually, alongside separate API plans. Detection limits, credits for presentation and humanizer usage, document history length and support level differ between tiers.

**Pricing & Plans:** Freemium with paid subscription tiers. Public annual-billing pricing lists roughly $8/month (Academic), $15/month (Writing) and $24/month (Ultimate), plus separate API plans and a free starting option with limited detection volume.

- **Multilingual detection across 80+ languages:** The detector is trained for broad language coverage rather than English-only use, which matters for international schools, multilingual newsrooms and cross-border content teams.
- **Sentence- and phrase-level analysis:** After the overall score, a second pass labels each sentence as Human, AI or Mixed and highlights the specific phrases pushing the score up.
- **Color-coded results and AI impact scores:** Flagged passages are highlighted in the document, and a ranked impact list lets you scroll to the highest-signal sentences first.
- **Bundled integrity toolkit:** Plagiarism checking, grammar proofreading, humanizing, an AI Editor and a presentation maker sit alongside the detector in one account.
- **Bulk scan and file upload:** Individual and batch file uploads plus high document-history retention on higher tiers suit educators grading many submissions at once.

**Strengths:** Broad language coverage compared with English-first detectors; Sentence and phrase breakdown makes results easier to act on; Several related writing tools included in one subscription; Bulk upload and document history suit high-volume users

**Limitations:** AI detection is probabilistic and can still produce false positives; Useful limits such as humanizer words and history length vary by tier; Heavier features require a paid plan

## 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
