Read full descriptionHide full description
PDF Scanner AI is a document scanner app for your iPhone. Scan documents to PDF, clean up blurry or shadowy photos, fill and sign forms, and translate them. Made for receipts, tax forms, leases, school forms, and notes. SCAN TO PDF โข Document scanner: point your camera at a page. The edges are found and the page is straightened for you. Scan many pages into one PDF. โข Image to PDF (JPG to PDF): turn photos from your photo library into one PDF. Pages are straightened, and you can drag the 4 corners. โข ID card scanner (front and back on one page), book scanner, and QR and barcode scanner. FILTERS AND PAGE FIXES (NEW) When you scan to PDF, give each page a look from 9 filters, like Auto, B&W, Gray, and Perfect, which evens out shadows and makes the paper white. Adjust brightness and contrast, and retake, crop, or rotate a page before you save. The Eraser wipes stains and marks off scanned pages. BLURRY PHOTO IN, CLEAN PDF OUT Layout PDF reads your page with AI and rebuilds it: โข Remove Background: the text is retyped in the same layout on a clean white page. โข Sharpen Text: your real page (paper, colors, signatures, handwriting) with blurry print made sharp. โข Keep Background: your original photo with searchable text. Works best on printed pages. AI TEMPLATES (NEW) Snap a handwritten estimate, notes, or a resume, and AI types it up: Estimate / Invoice, Resume, Typed Notes, Meeting Notes, Recipe Card, or Clean Document. It even flags totals that don't add up. Save it as a PDF (most templates also save as Word). FILL AND SIGN WITHOUT A PRINTER Add text and your signature (drawn with your finger) to any PDF. Fill in a school form or sign a lease, then send it right away. FIX A TYPO WITHOUT RESCANNING Scan with Layout PDF, tap Edit text, and change a line. The page is rebuilt in place. IMAGE TO TEXT (OCR) Text Recognition reads the words in your photo in 24 languages. Copy them, search them, or save them as a TXT file, and get a searchable PDF too. Needs an internet connection. TRANSLATE PDFS AND SCANS Translate a scan, a PDF with text, or a Word or TXT file into any of 24 languages, like Spanish, Chinese, and Vietnamese. Save the translation as TXT or Word. PDF TO WORD Turn a scan into an editable Word file (.docx). Tables, headings, bold text, and alignment carry over. BILL REMINDERS (NEW) Scan a bill to track it and get reminded before the due date. See what's due this month, mark bills as paid, and get weekly and monthly summaries. OPEN THE PDFS YOU ALREADY HAVE Open a PDF from Mail, Files, Google Drive, or your browser, search for any word (even in photos of printed pages), and use every tool on it. Save any document to the Files app in one tap. PDF TOOLS AND SHARING See your pages two to a row and drag them into order, add pages to any document, or delete one. Compress a PDF to email it, merge PDFs, split out the pages you need, and lock a PDF with a password. Share as PDF, Word, TXT, images, or a ZIP file. Compress, merge, and split run on your iPhone, so those files are not uploaded. FREE AND PREMIUM Free: 3 scans a week, up to 5 pages each (a short ad adds 3 more pages). After that, a short ad unlocks each extra scan. AI templates read 1 page. You get 1 free try of Translate or AI bill reading. Adding bills by hand is always free, and your scans have no watermark. Premium: unlimited scans up to 20 pages each, no ads, the Perfect filter, Translate, AI templates up to 20 pages, and AI bill reading (up to 30 bills a day). Premium is a subscription (weekly, monthly, or yearly). Cancel anytime in your Apple Account settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
MDReader

MDReader opens your Markdown files and folders and renders them properly. There is no library to import into, no account to create and no sync service in the middle. Your .md files stay exactly where you put them, and MDReader reads and writes them in place. FAST, EVEN ON BIG FILES A two-tier parser scans a document in a single pass and only fully parses the blocks you can actually see. A 10 MB file opens before other editors have finished showing a spinner, and scrolling stays smooth all the way down. RENDERS THE WHOLE OF MARKDOWN GitHub-flavoured Markdown with tables, task lists you can tick straight from reading mode, footnotes that jump both ways, YAML front matter shown as a card, LaTeX math inline and display, fenced code with syntax highlighting, and Mermaid diagrams rendered offline. AN EDITOR THAT STAYS OUT OF THE WAY Live syntax highlighting, lists that continue and renumber themselves, bold/italic/link shortcuts, find and replace, table and formula inserters, and paste an image to save it next to the document. Autosave goes through the system file coordinator, so editing alongside Obsidian, git or iCloud is safe. PICKS UP WHERE YOU LEFT OFF Reading position is restored to the pixel, per document, across relaunches, rotation and window resizes. FOLDER WORKSPACES (PRO) Open a whole folder: a repository's docs, an Obsidian vault, a Zettelkasten. Fuzzy quick-open, full-text search across every file in the folder, [[wiki-links]] with a backlinks panel, a front-matter tag browser, and read-only git status per file. Changes made by other apps are picked up in place, without losing your position. MORE IN PRO PDF export and print, publishing to GitHub Gist and Telegraph, presentation mode for slides, a custom theme editor with imported fonts, focus and typewriter modes, word-count goals, reading statistics, text-to-speech with follow-along highlighting, local version history with diffs, snippets, Vim keybindings, and an AI pack that summarises and rewrites entirely on device. BUILT FOR APPLE PLATFORMS One purchase covers iPhone, iPad and Mac. Keyboard shortcuts throughout, multiple windows, menu bar commands, a Share extension, Shortcuts actions, widgets, a URL scheme, Spotlight indexing, VoiceOver labels and Dynamic Type. PRIVACY MDReader collects nothing. No analytics SDK, no account, no server of ours to talk to. The only network traffic is what your own documents ask for, such as remote images, plus the publishing integrations you set up yourself. FREE AND PRO The reader and the single-file editor are free forever: all rendering including math and syntax highlighting, the base themes, table of contents, in-file search, HTML, Markdown and plain-text export, and position restore. Pro unlocks folder workspaces and the power features above, as a one-time purchase or as a yearly subscription with a free trial. SUBSCRIPTION AND PURCHASE DETAILS MDReader Pro (Yearly) - auto-renewable subscription, 1 year, USD 9.99 per year, including a 7-day free trial for new subscribers.

Verdict
The clearest difference is ads: MDReader at none against PDF Scanner AI's shown. PDF Scanner AI's advantage is iOS requirement (17.0 vs 26.0). On price, update cadence, in-app purchases and device support there is nothing between them.
