Inkiostro is a Markdown editor for people who write — notes, documentation, theses, novels. Plain text files that stay yours, a preview that looks like a finished page, and exports ready to hand over. Write in Markdown, or in the visual editor and never see a symbol. Buy once, no subscription. No account, no tracking. WRITE, SEE, FINISH • Two ways to write: the Markdown editor shows the symbols, the visual editor formats as you type, like a word processor. Either way the file stays plain Markdown. (Visual editor: Pro, free for 7 days) • A complete Markdown toolbar: headings, lists, tables and code blocks, one tap away. • A side-by-side preview that comes back exactly where you left it. • LaTeX formulas typeset by KaTeX, and Mermaid diagrams drawn as you type. • 27 preview styles, 11 of them free: GitHub, Sepia, Nord, Solarized and more. With Pro, Manuscript, Book, Report, Academic and others set the page like print. • Focus and Typewriter modes, a live word count and a daily writing goal. FROM DRAFT TO BOOK • PDF with selectable text, formulas and diagrams included. Free, with a small credit line in the footer. • A professional ePub: real chapters, a cover, ISBN, series, footnotes that open over the page, and the accessibility declaration Europe requires. The export sheet tells you what a store would reject — before you send it. (Pro) • A book made of many files: one chapter per file, in a folder, in the order you choose. Arranging it is free; exporting it as a single ePub is Pro. • Self-contained HTML, and page setup for PDF: paper, margins, headers and page numbers. (Pro) NEVER LOSE A WORD • Version history: Inkiostro saves versions as you write. Search them, compare them line by line, and bring back a single word or a whole draft. (Pro) • Backups of your whole library: a dated zip archive with your version history inside, offered when one is due, while the app is open, in a folder you pick. Open it in the Files app and your Markdown files are right there. (Pro) YOUR FILES, YOUR RULES • Unlimited documents, as plain .md files you can open anywhere. • Folders, color labels and tags, with search that filters by tag. • iCloud Drive sync between iPhone, iPad and Mac, with no setup. • External folders: work directly inside any folder on your device or in iCloud Drive. (Pro) INKIOSTRO PRO — ONE PURCHASE, EVERY DEVICE One purchase unlocks Pro on iPhone, iPad and Mac, forever. Try it free for 7 days. • The visual editor • Version history with search, comparison and a year of versions • Backups of your library • Professional ePub, HTML, and books made of many files • PDF page setup • Focus and Typewriter modes • External folders • 24 app themes, the Pro preview styles and any font installed on your device MADE FOR • Writers: novels and essays in plain text, out as a real ebook • Students and researchers: notes and theses with proper formulas • Developers: READMEs, documentation and technical notes with diagrams • Anyone tired of paying every month for a text editor • Anyone new to Markdown: the visual editor works like a word processor PRIVACY Your documents stay in your iCloud Drive or on your device. No servers of ours, ever. Inkiostro collects only anonymous, aggregated usage statistics — never personal data, never the content of your documents — and you can turn them off in Settings.

About

Lobster

Write what only you can say. Catch the thought where it finds you. Connect the scattered pieces. Work the sentences until they hold. Then export something a reader can actually read. Lobster keeps every stage of a piece of writing in one library — a novel, a blog post and a diary all live in the same drawer. CATCH IT WHERE IT HAPPENS — Catch Ideas Good sentences rarely arrive at the desk. The Catch Ideas button sits in the same place on every screen: one press captures text, a photo, a video, a voice recording or where you are. Anything shared to Lobster from another app lands there too. It all collects in the Idea Aquarium until you are ready to use it. SCATTERED PIECES FIND EACH OTHER — Interstellar View Sheets that share a keyword are drawn together — dotted lines for keywords, solid lines for links you made yourself. Seeing that last year's note already touches today's chapter gives you a sentence a list of files never would. A PARAGRAPH, SENTENCE BY SENTENCE — Writing Studio Lobster lays a paragraph out one sentence at a time, with a rewrite line under each. Compare, pick the one you want, drag sentences into a new order. Only what you choose goes back into the manuscript, and the original stays safe while you work. SEE HOW MUCH OF IT IS YOURS — Voiceprint Research leaves other people's sentences in a draft. Voiceprint separates what you pasted from what you wrote and shows you the balance, sheet by sheet. Copying a passage to learn from it? Turn on transcription mode and it won't count against you. BUILD THE PAGE YOU EXPORT — Style Studio Preview the page your PDF or DOCX will become, large enough to actually read. Adjust headings, body text, quotes and notes right there. A FULL MARKDOWN EDITOR • Headings, lists, quotes, code, footnotes, tables, images, equations and a table of contents • Sheet links, bookmarks, annotations and a second editor side by side • A dashboard with statistics, progress, outline, notes, keywords and more • Writing goals by words, characters, lines or pages, with a deadline • Eight writing types — essay, novel, blog, magazine, reporting, social, diary and freeform — each with its own starting structure EXPORT PDF, DOCX, ePub, HTML and plain text, plus print with page and paragraph numbers. YOUR WRITING, KEPT SAFE • There is no server. Your manuscript lives on your device; iCloud keeps your Mac, iPhone and iPad in step. • There is no AI. Lobster never writes your sentences and never sends your writing anywhere. • Automatic hourly, daily and weekly backups, saved versions and a trash. • Lock the app with a password, Touch ID or Face ID. NOT A SUBSCRIPTION Use every feature free for five days. If Lobster earns its place, buy it once — no renewal, no next charge. One purchase opens Lobster on Mac, iPhone and iPad. If the trial ends before you buy, only editing locks: everything you wrote stays readable, searchable and exportable. Available in English, Korean, Japanese, German and French.
