About

NextPaper

Read full description

NextPaper is a Zotero companion that turns your library into a reading queue. Zotero is great for collecting papers, but it’s easy to lose track of what to read next. NextPaper gives your library a simple structure you can actually work through. Browse your collections, pick papers that matter, and add them to your NextPaper list. When you finish reading something, mark it as read and move on. Your progress is reflected directly in Zotero, so everything stays in sync. See the essentials at a glance β€” title, authors, abstract, and publication β€” without needing a desktop app. Designed for researchers who already use Zotero. There’s no new account to create. Just connect your library and start organizing your reading. Your data stays yours. NextPaper uses secure OAuth to connect to Zotero and doesn’t store your password or your library content.

You find a link worth saving. You read a quote worth keeping. You discover a band worth remembering. By the time you switch apps, find the right file, and paste it in β€” you've lost your train of thought. AppendX gives you two ways to get it down. Share from any app on your iPhone, or open AppendX and capture a thought that isn't on screen anywhere. Either way it lands in exactly the right markdown file, formatted exactly how you want it. SMART TARGETS Set up your destinations once β€” a file for books, one for links, one for ideas. Each with its own emoji, format, and file. AppendX reads your files' headings to name targets automatically, and suggests icons as you type. LISTS, BLOCKS, OR YOUR OWN FORMAT Capture as a clean list item that adapts to whatever you share, a block that keeps every piece of data, or build a custom template with tokens. A live preview shows exactly what will land in your file β€” before you commit. PASTE AS MARKDOWN Copy a paragraph from the web and paste it into AppendX. Bold stays bold. Links stay links. iOS hands most apps plain text and drops the formatting β€” AppendX reads the clipboard's HTML instead, so what you copied is what you keep. TYPE, TALK, OR PASTE Capture mode opens straight to a text field. Type it, dictate it with the keyboard's microphone, or paste formatted text from anywhere. SMART CAPTURE Different apps share data differently β€” AppendX sorts it out. Clean URLs with tracking junk stripped. Real titles instead of bare hostnames. Selected text recovered even when apps bury it in odd places. What you meant to save is what gets saved. NEVER LOSE DATA Every capture is queued locally before it's written. If iCloud hiccups, your capture waits safely and syncs when your files are reachable. A full history shows everything you've captured and its status. WORKS WITH YOUR SETUP Any app that stores markdown files: Obsidian, iA Writer, 1Writer, or a plain folder. iCloud Drive or on-device storage. No account, no analytics, no server β€” your notes never leave your control. Free, with an optional tip jar if it earns a place in your routine.
