Folio Writer is a plain-text writing studio for long-form work — scholarly manuscripts, books, and novels. This is its iPhone and iPad edition: the same projects, the same files, in your pocket. Open a project from iCloud Drive, Dropbox, any Files location, or your Folio Cloud account, and pick up exactly where you left off on the Mac. Everything you write is a plain Markdown or Typst file you own — no lock-in. WRITE ANYWHERE — FREE A Markdown key bar puts #, *, links, code, and $math$ one tap away. Typewriter scrolling and sentence focus for drafting on the go. Live word count and writing targets for each document, the whole draft, and each session. Hardware-keyboard shortcuts on iPad. YOUR WHOLE PROJECT — FREE The full binder: browse, open, rename, reorder by dragging, indent and outdent, and create new documents. Project-wide search with filters — label:, status:, type:, tag: — and saved searches as Collections. Version history: every save is kept and restorable, so nothing you write is quietly lost. Comments, and the Review Inbox for suggestions from co-authors. CITATIONS & PREVIEW — FREE Insert citations from the project's BibTeX files by author, year, or key. Preview the rendered document — headings, tables, images, and LaTeX math — right on the device. SYNC WITH THE MAC AND FOLIO CLOUD — FREE Opens the exact same .folio projects as Folio Writer for Mac, byte-for-byte. Conflict-safe syncing: edits from two devices merge when they don't overlap, and a losing copy is always preserved. Sign in to Folio Cloud and every project your account owns is listed; create projects in the cloud, share by link, co-edit live, and protect encrypted projects with a recovery passphrase. FOLIO PRO — ONE PURCHASE FOR MAC, iPHONE, AND iPAD Pro adds the finishing tools: Preview Manuscript — the whole draft assembled in binder order with its title page. Suggesting — propose edits as tracked changes, then Accept or Reject each one from the review bar, and mark a document as reviewed. Snapshots — named copies to compare side by side and roll back, change by change. Insert Template, with starter snippets for figures, tables, equations, and more. Compile to PDF, Word, or Typst through Folio Cloud, right from the device. Pay once, unlock both platforms. Folio Pro is the same one-time purchase as in Folio Writer for Mac: buy it here and Pro unlocks on your Mac; buy it on the Mac and it unlocks here. It follows your Apple ID — tap Restore Purchases if it hasn't appeared. Every Pro feature is free to try for 7 days. Prefer to pay by the month or year? Pro ($1.99 a month) and Premium ($3.99) are also available as subscriptions, which unlock the tier here and on the Mac for as long as they run and come with complimentary Folio Cloud storage (1 GB or 3 GB), so your projects sync to every device and open in any browser. PRIVATE BY DESIGN No analytics, no trackers. Your manuscripts never leave your own devices except through the cloud service you choose, and Folio Cloud projects are end-to-end encrypted.

About

ScholarSide

Features
Read full description

ScholarSide turns a pile of papers into a reading plan. It's a focused reading system for researchers, grad students, and anyone who reads academic papers with purpose — not another PDF dump, but a way to decide what to read, how deeply, and what you got out of it. Add a paper by arXiv link, arXiv ID, or DOI and ScholarSide fills in the title, authors, venue, and abstract for you. Every paper gets a card built around one simple idea: a reason you saved it. No more folders of mystery PDFs. TRIAGE, DON'T HOARD • A pipeline board from Inbox to Finished, with drag-and-drop and one-at-a-time triage • Give every paper a reason: background, method, baseline, to implement, assigned, or just curious • Flags for meeting prep, relevance, and how well you actually understand it READING MODES Not every paper deserves a deep read. Pick a mode and ScholarSide guides you with a timed checklist: • 5-minute skim — should I read this at all? • 20-minute structured read — understand the contribution • 60-minute deep read — own the method and the math • Implementation read — extract everything needed to reimplement STRUCTURED NOTES Capture a paper the way you think about it: problem, method, key equations, algorithm, experiments, results, limitations, and open questions — plus a confusion tracker, so "I don't get this part" becomes a to-do instead of a dead end. PROJECTS & REVIEW • Group papers into research projects with a reading order and open questions • A weekly review that surfaces stale papers, unresolved confusions, and what to read next • Lab-meeting prep built from your own notes OPTIONAL AI ASSIST (BRING YOUR OWN KEY) Add your own Anthropic API key and Claude can draft a summary, fill in the structured notes, or explain a paper at the level you choose — always as an editable draft that sits beside your own notes, never replacing them. Your key stays in the device Keychain and usage is billed to your account. The app is fully functional without it. PRIVATE BY DEFAULT No account. No ads. No tracking. Everything lives on your device. Export notes to Markdown and your library to BibTeX any time.
