StrataWrite is a research-first writing app designed for scholars, researchers, and serious writers who need more than just a blank page. Built with Apple’s native frameworks, StrataWrite unites structured note-taking and manuscript drafting in a clean, focused environment that helps you organize complex projects and keep your ideas connected. StrataWrite is for text only. No Table or Image support. StrataWrite is about getting the words out and not formatting. StratWrite is the first step in writing up your research. Get the words out in either Notes or Manuscript Views. When the first draft of your writing is complete, export to Plaintext or Markdown and import it into your favorite Word Processor for formatting. Whether you are preparing a dissertation, drafting a grant proposal, or developing a book chapter, StrataWrite provides a workspace designed to keep your research structured and your writing clear. Research-Driven Writing StrataWrite is built for projects that demand more than linear word processing: • Structured Notes – Capture and organize your research with tags, categories, and backlinks. Notes connect into a system that grows as your ideas develop. • Manuscript Drafting – Write in a distraction-free workspace with daily word count goals, progress tracking, and export options for Markdown, or TXT. • Linking Ideas – Create bidirectional links between notes and manuscripts, building a network of connections that keeps your sources and insights close at hand. Native Apple Experience StrataWrite is built with SwiftUI and designed to feel at home across macOS and iPadOS: • Universal App – Switch seamlessly between Mac and iPad. StrataWrite adapts to your workflow, wherever you are writing. • CloudKit Sync – Keep your notes and manuscripts securely up to date across devices. • Clean, Distraction-Free Interface – A modern, lightweight design emphasizes your writing while keeping structure available when you need it. Designed for Focus & Clarity StrataWrite emphasizes research structure without unnecessary complexity. Notes and manuscripts are part of the same system, allowing ideas to move fluidly between your research base and your drafts. By connecting thoughts through links and tracking progress as you write, StrataWrite helps you transform research into finished work with confidence. Made for Scholars and Writers If your projects depend on clarity, depth, and organization, StrataWrite was built for you. Graduate students writing theses, researchers assembling journal articles, and professionals developing long-form work will all find a workspace that supports rigorous thinking and clear writing.
