The classic side of the product covers the essentials most people need every day: viewing and editing PDF text and images, converting between PDF and Office/image formats, OCR for scanned files, merging, splitting, compressing, watermarking, signing and annotating. Because everything runs in the browser with companion apps for Windows, Mac, iOS and Android, the same account and files travel with you across devices. The AI layer is where the product has expanded most. An AI agent lets you chat with an uploaded document, ask follow-up questions and trace answers back to citations, while a separate chat experience works on YouTube videos. Document translation preserves the original layout across 20+ languages, including scanned and image-based PDFs, and structured data extraction turns invoices, receipts, bank statements and purchase orders into editable spreadsheets. Rounding out the suite are an AI PPT generator, mind-map and summary generation, watermark and sticker removal, text and logo erasing, document enhancement for scanned pages and an AI invoice generator. Pricing follows a freemium model with a free tier (10MB file limit, watermark on some exports) and paid plans that add unlimited file sizes, batch processing, cloud storage and monthly AI credits. Individual subscriptions start around $5.99 per month, with a yearly option near $15.99 and a one-time lifetime plan; credits are consumed per AI action, so heavy AI users can top them up. Team, business and education plans are available on request. **Pricing & Plans:** Freemium. A free plan covers basic PDF tools with a 10MB file cap; paid plans start around $5.99/month, with a yearly tier and a one-time lifetime option.

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) ## Frequently Asked Questions ### How do LightPDF and Scribbr compare in monthly traffic?
