## 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

## StrongestLayer

StrongestLayer was founded by operators who helped build the previous generation of email security at Proofpoint, McAfee, Google, Mandiant and FireEye. Their central argument is that AI now writes attacks from scratch, so rules miss them because they are new and machine learning misses them because they look routine. In response, the platform asks a different question: what is this email trying to accomplish?

The product is built around TRACE, a multi-LLM reasoning engine that organises its agents into three classes: Advisor, which returns a verdict on every email; Triage, which delivers pre-investigated cases; and Hunt, which sweeps the organisation from one sample. Intent Workflows extend the same reasoning to payment and access requests, and to hidden prompt-injection instructions aimed at AI assistants like Copilot, Gemini and Claude.

Deployment is deliberately low-friction. StrongestLayer connects through the Microsoft Graph or Google Workspace API in roughly fifteen minutes with no MX changes, so it runs alongside Proofpoint, Mimecast or native filtering. Every plan starts with a 14-day proof of concept that measures threats reaching inboxes and analyst time saved before you commit.

**Pricing & Plans:** Custom pricing quoted per mailbox, scoped to your deployment size and mail platform. There is no public price list; every engagement starts with a 14-day proof of concept that runs alongside your current stack.

- **TRACE reasoning engine:** A multi-LLM ensemble reads intent, checks each message against your business context and relationships, and returns a clear verdict instead of relying on signatures or anomaly scores.
- **Inbox Advisor:** Get a plain-English verdict on every message, so anyone on the team can understand why an email was allowed or blocked without reading raw headers.
- **Threat Triage:** Reported phish arrive as pre-investigated cases complete with the evidence and reasoning trace your SOC needs to close them quickly.
- **Threat Hunt:** Turn a single suspicious email into an organisation-wide sweep to find related messages that other filters delivered.
- **Intent Workflows:** Verify payment and access requests against your policies before anyone acts, and detect hidden instructions aimed at AI assistants such as Copilot, Gemini and Claude.

**Strengths:** Reasons about intent rather than relying on signatures or anomaly scores; Rapid API-based deployment with no MX changes; Plain-English reasoning trace on every verdict; 14-day proof of concept before purchase

**Limitations:** Pricing is quote-only, so small teams cannot self-serve or see list prices upfront; Focused on Microsoft 365 and Google Workspace mailboxes, so it is not a fit for other mail platforms; Agentic reasoning layer adds depth that smaller organisations without a SOC may not fully operationalise
