About Markup
FreemiumIntermediateNo APIWeb
Markup is a web-based document annotation tool powered by GPT-4, designed to streamline the process of analyzing, highlighting, and extracting insights from PDFs, web pages, and other documents. It targets researchers, students, journalists, and professionals who need to manually annotate and summarize large volumes of text with the assistance of AI. The tool works as a progressive web application accessible from any modern browser. Users can upload documents or paste URLs, then apply highlights, notes, and tags manually. GPT-4 integration enables automatic summarization, question answering, and extraction of key findings from selected text. Fast search and filtering across annotations reduces time spent revisiting documents. Markup differentiates itself by combining manual annotation with AI-powered analysis, providing an all-in-one workspace for document review. It supports export to various formats, including PDF and text, and offers team collaboration features. The emphasis on privacy ensures that annotations remain local in the browser or on the user's storage. While the AI features are a key differentiator, they require an internet connection and usage of GPT-4 tokens. The tool is suitable for individuals and teams dealing with lengthy documents, such as academic papers, legal briefs, market research, and due diligence materials. Markup aims to reduce cognitive load by letting AI handle synthesis while users focus on critical insights.
Behind the Verdict
Markup stands out by putting you in control of your annotations while letting GPT-4 do the heavy lifting on summarization and Q&A. The web-only approach is a double-edged sword—accessible from any device but useless offline. The free Starter plan is genuinely usable for light academic work (5 docs/month), but professional researchers will quickly hit the 100-doc cap on Pro. Team collaboration works well for small groups, but the lack of integrations with reference managers like Zotero or Mendeley is a missed opportunity. If you just need to highlight PDFs and get AI summaries, Markup is a solid choice. But if you need deep integration with your existing research workflow, you might prefer a more ecosystem-heavy tool.

Where the pricing makes sense
The company stage and team size where Markup's pricing actually pencils out — and where peers do it cheaper.
