Papyrus vs Wikova

Papyrus is a native research workspace for reading, annotating, organizing, and citing PDFs — built for iPad, iPhone, and Mac. READ AND ANNOTATE Open a paper in a fast built-in reader. Highlight, underline, and mark up pages, and every highlight stays searchable and linked back to its source. Bookmark a page as you go, and pick the paper up later from a Reading card that remembers where you stopped. On iPad, a References tab looks up the open paper's reference list and related work, so you can follow a citation trail and add what matters to your library without leaving the page. WRITE ON THE PAGE WITH APPLE PENCIL Mark up a PDF directly on iPad — annotate a proof, sketch beside a figure, work a derivation out in the margin. Your ink belongs to the paper and travels with it, encrypted, to your other devices. NOTES BESIDE THE SOURCE Keep Markdown notes next to each paper: headings, tables, code blocks, LaTeX math, and [[note]] cross-references. Notes stay with the paper and export as PDF when you need to share them. NOTEBOOKS Gather notes from across your library onto themed shelves — a topic, a chapter you're drafting, a reading group. Filing a note copies nothing and moves nothing: it still belongs to its paper, still says which paper that is, and one tap takes you there and back. A note can sit on several shelves at once. Fill a new shelf from what you've already written, search it by a note's text or by the paper behind it, order it four ways — including oldest paper first, which reads your own notes forward through the literature — and export a whole shelf as one Markdown document. All Notes lists everything you've written in one place, filed or not. ORGANIZE THE WAY YOU THINK Folders — a paper can live in several — plus tags, star ratings, and seven colored flags you can name yourself, each with its own shape so they stay tellable apart at a glance. Smart Collections keep themselves current from rules you set, including flag rules. Review Duplicates finds look-alike papers and merges each set after you confirm, combining tags, folders, projects, notes, and highlights. FIND ANYTHING Search titles, authors, notes, and highlights — or the full text inside your PDFs. TURN READING INTO WRITING Projects are where a reading pile becomes a manuscript. Group the papers behind a chapter or article, give each one a role, and capture evidence — claims, quotes, and your own interpretation — tied back to the source paper and page. Write the project note from a template (related work, method comparison, experiment plan, thesis chapter, reviewer response), keep its revision history, and run a preflight that catches missing citation keys and metadata gaps before you export. Export a bundle with Markdown, a BibTeX bibliography, and the PDFs. IMPORT AND CITE Bring in PDFs, whole folders, or BibTeX and RIS files — including libraries exported from Mendeley and Zotero. Papyrus looks up metadata by DOI or arXiv ID and fills in the details. Save papers straight from Safari with the included extension. Copy citations in the style you write in, and export BibTeX or RIS whenever you need them. READ ANYWHERE Paste an arXiv link, a DOI, or a PDF URL and Papyrus imports it, looks up the details, and fetches the PDF. Add a paper to Read Later and its PDF downloads ahead of time, so a flight or a commute doesn't need a signal. Ask Siri, or search from the Home Screen, to pick up the paper you were last reading on the page you left it. YOUR LIBRARY, YOUR DEVICES Your library syncs over iCloud across iPad, iPhone, and Mac. No account to create, no tracking, no ads. Free to download and use — every feature included, no in-app purchases, no subscription.

Turn every spark of curiosity into a wiki that grows on its own. Wikova is a personal knowledge base powered by a team of AI agents. Give it a topic, and a researcher agent goes online to gather sources, an editor agent turns them into structured wiki entries, and a maintainer agent quietly comes back every day to fact-check, refresh, and fill in the gaps. Instead of scattered tabs and notes, you get a private, searchable, shareable encyclopedia of the things you care about. — WHAT'S INSIDE — • AI agent team — research, writing, editing, and maintenance, fully automated • Cited sources — every claim links back to the original page, one tap away • Daily auto-refresh — followed topics keep updating, so nothing goes stale • Health check — auto-detects contradictions, outdated facts, and orphan pages • Three query modes — Fact, Synthesize, and Speculate, switchable per question • Knowledge graph view — see how topics and entities connect at a glance • Flexible sharing — private, link-only, or fully public, your call • Hybrid search — keyword and semantic in one query — WHO IT'S FOR — • Curious minds who love going deep on niche topics • Researchers, journalists, and investors tracking a domain over time • Knowledge workers building a personal or team knowledge asset • Students who need to make sense of complex subjects — WHY WIKOVA — Notes need you to organize them. Search engines won't remember for you. AI chats forget the moment you close the tab. Wikova hands research, distillation, and upkeep to a team of agents, so every question you ask compounds into a knowledge asset you actually own. Pick a topic you're curious about. Let the agents do the rest.
