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 [Profile (Markdown)](https://openaitools.app/tool/scribbr.md) ## TopPDF TopPDF is a browser-based toolbox that concentrates the document tasks people do most often into one place. You can edit text and images inside a PDF, translate a document while trying to keep its layout, compress files for easier sharing, merge several PDFs into one, or split a large file into smaller pieces. A converter handles two-way movement between PDF and Word, Excel, PowerPoint and JPG, with EPUB to PDF on the import side as well. Beyond conversion, the platform adds light AI writing help: a grammar checker that detects grammatical and spelling issues across multiple languages, and a paraphrasing tool for rewriting passages quickly. OCR support means scanned or image-based documents can be turned into searchable, editable files, which is often the deciding factor for anyone working with older or printed material. TopPDF says it is used by more than 8 million people and has processed over 150 million PDFs, and the interface is offered in a wide range of languages. Access is freemium: the core utilities can be tried without an account, while a subscription unlocks larger files and more advanced editing. Because pricing is presented inside the product rather than on a public page, it is worth checking current plans in the app before committing. **Pricing & Plans:** Freemium. Core PDF tools such as editing, conversion and compression can be used for free with limits, while a paid subscription unlocks larger files, advanced editing and higher usage volumes. Exact plan prices are shown inside the product rather than on a public pricing page, so check the app for current tiers. - **PDF editing and translation:** Modify text and images directly inside a PDF and translate document content into many languages while keeping the original page layout intact. - **Compress, merge and split:** Shrink, merge and split PDFs so large documents are easier to store, share and organise, with compression that aims to preserve visible quality. - **Two-way format conversion:** Convert PDFs to Word, Excel, PowerPoint and JPG, and convert Word, Excel, PowerPoint, JPG and EPUB back into PDF. - **AI grammar checker and paraphraser:** An AI grammar checker that finds grammatical errors and spelling mistakes across multiple languages, plus a paraphrasing tool for fast rewriting. - **OCR for scans:** OCR support turns scanned or image-based documents into editable, searchable formats so printed material can be reused digitally. **Strengths:** Wide all-in-one toolkit covering editing, conversion, compression and translation; Two-way conversion between PDF and Word, Excel, PowerPoint and JPG; Multi-language interface and a PDF translator covering many languages; OCR makes scanned and image-based documents editable **Limitations:** Some advanced features and larger files sit behind a paid subscription; No visible pricing page makes cost comparison harder before signing up; Heavy PDFs with complex layouts may still need manual fixes after conversion; Site language switcher covers many languages but the interface focus is document conversion rather than a wider productivity suite [Profile (Markdown)](https://openaitools.app/tool/toppdf.md) ## Frequently Asked Questions ### How do Scribbr and TopPDF compare in monthly traffic?
