## 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

## Smart Assistant by Mailbutler

Mailbutler is an email productivity extension for Apple Mail, Gmail, and Outlook, and its AI component is the Smart Assistant. Rather than being a standalone chatbot, the assistant is embedded in the compose and read views of the inbox you already use. It can compose an email from a few short keywords, draft a reply framed as positive, negative, or neutral, summarize an entire thread, or correct grammar and phrasing in a draft — all without switching apps or copying text elsewhere.

The AI layer is deliberately connected to the rest of Mailbutler's toolkit. Follow-up suggestions analyze tracked emails — opens, link clicks, and engagement patterns — then classify threads as high, medium, or low priority, and the Smart Assistant can draft the follow-up itself. That combination of tracking data plus generation is what makes the assistant useful in sales and client-facing work, where knowing who to chase matters as much as what to write.

The rest of the extension supplies email tracking, message templates, mail merge, smart timing, tasks and notes, shared inbox assignments, and signature marketing. On privacy, Mailbutler is ISO/IEC 27001 certified and GDPR compliant with servers in Frankfurt, Germany. Emails are still sent from your own server, message content is not analyzed or stored in the backend for general operation, and when you use the Smart Assistant the email body is sent to OpenAI only for that request, with email addresses replaced by dummy variables. Plans range from a free-forever Starter tier to paid Smart and Business plans, all starting with a free 14-day trial that includes every feature and no credit card requirement.

**Pricing & Plans:** There is a free-forever Starter plan plus a free 14-day trial with all features and no credit card. Paid tiers are billed per user per month (about $4 Starter, $7 Professional, $11 Smart, and higher Business pricing when billed yearly, with monthly pricing slightly higher) and available in USD or EUR. The AI Smart Assistant is included from the Smart plan upward; email tracking, templates, mail merge, tasks, and signatures are spread across the tiers.

- **AI drafting and reply generation:** Turn a handful of keywords or bullet points into a full, sendable email, and generate replies framed as positive, negative, or neutral depending on the situation.
- **Thread summarization:** Condense long email chains into the key points so you can catch up fast and respond without re-reading every message.
- **Grammar and tone correction:** The assistant rewrites and corrects your message for grammar, spelling, and phrasing before you hit send.
- **Smart Follow-ups:** Follow-up suggestions combined with open and click tracking tell you which threads are urgent, and the assistant can draft the follow-up for you.
- **Built into a full email toolkit:** The AI features sit alongside tracking, message templates, mail merge, tasks and notes, shared inbox assignments, and email signatures so your whole workflow stays in one inbox.

**Strengths:** Works inside Apple Mail, Gmail, and Outlook instead of forcing another app into your stack; AI drafting, summarization, and grammar checks are combined with tracking and follow-up prioritization in one place; Strong privacy posture: ISO/IEC 27001 certified, GDPR compliant, and servers located in Germany; Free 14-day trial unlocks all features with no credit card required

**Limitations:** Most genuinely useful AI features require a paid plan, and full automation sits on higher tiers; Free tier is limited, so the free-forever Starter plan is best treated as a lite entry point; Used for email drafting, email body text is transmitted to OpenAI (addresses are tokenized), which some compliance teams will want to review; Feature depth varies slightly by client since it is an extension layered over three different email apps
