Markdown notes are easy to write — and easy to forget. markru is built for what comes after writing: shelving, binding, and rereading your own notes like books. (Markdown writing, shelving, binding, and rereading all work without AI; only the AI helpers, such as tag suggestions and summaries, need a supported device and settings where Apple Intelligence is available.) No markru account to sign up for. Import .md and .txt files, and export your notes as .md files or a ZIP. YOUR NOTES, SHELVED LIKE BOOKS Promote finished notes from drafts to your bookshelf. Browse by shelf, search, and sort by what you read last. BIND NOTES INTO ONE READABLE BOOK Combine related pages into one book. Reorder pages, add new ones, and read them as a single piece — or unbind anytime. WRITE IN CLEAN MARKDOWN A focused Markdown editor with a formatting bar for headings, lists, checklists, tables, code, and more. Save your note, then read it in a clean, formatted layout. Some writing helpers — tag suggestions, formatting, and summaries — are partly powered by Apple Intelligence, on your device by default. Note: Whether the AI helpers appear depends not only on your device, but also on whether Apple Intelligence is turned on and ready. To check your device, open Settings in markru and look under Apple Intelligence. Where it isn't available, these helpers fall back to manual entry — everything else in the app still works. If you turn on Private Cloud Compute in the app's settings, formatting, summaries, and save comments are processed by Apple's Private Cloud Compute instead; tag suggestions always stay on your device. Your notes are never sent to our servers or any third-party server. CAPTURE IDEAS IN SECONDS Quick Capture works like a paper memo: jot it down, the title can come later. Send text from any app with the share sheet. IMPORT & EXPORT Import .md and .txt files. Export notes as .md files, or bundle them into a single .zip. KEEP YOUR SHELVES IN ORDER See your note, shelf, and book counts at a glance. Select the paragraphs you need and bring them together in a new note. Clean up or bind notes as your library grows. PICK UP RIGHT WHERE YOU LEFT OFF markru remembers your reading progress in every book, so returning to your notes feels like reopening one. USAGE AND COLLECTION LIMITS You can currently use markru without making a purchase. Your collection starts with room for 100 books and can be expanded without a purchase in steps of 50, up to 300. Each standalone page or book on your bookshelf counts as one book. Pages inside a bound book do not count separately toward your collection. PRIVATE BY DESIGN Your notes live as plain Markdown files on your device or in iCloud Documents — never on our servers. iCloud sync uses the Apple Account signed in on your device, with iCloud Drive turned on — not a markru account. Without iCloud, notes are saved on this device. Write lightly. Reread deeply.

Keep useful AI conversations close at hand. Arcora brings your DeepSeek, ChatGPT, Claude, Grok, and Gemini exports together on iPhone and iPad for offline reading, search, and review. You do not need to connect your AI service accounts. Imported archives are processed on your device. A library you can revisit • Browse conversations by source and read Markdown, code blocks, and tables. • Search messages within a source to find ideas, answers, and project notes. • Check import history and notices to understand what was saved and what the export did not include. Bring context to your next AI assistant Create an AI memory transfer package from selected conversation excerpts. Review the content, then copy it or export a Markdown file to share with your chosen AI assistant. Choose sources and dates, exclude conversations, and redact common sensitive information locally. The package contains excerpts and instructions; Arcora does not sign in to another AI service or automatically write to its memory. Always review the content before sharing. Start free. Upgrade once. The free version includes one successful import per source, continued reading of imported conversations, and search within that source. Preview a memory transfer package with up to 3 conversations and 6,000 characters. Arcora Pro is a one-time in-app purchase with no subscription. It unlocks: • Unlimited imports for each source. • Cross-source search with advanced source, role, and date filters. • Markdown and PDF conversation exports. • Monthly trends, activity heatmaps, and conversation statistics. • Extraction and preview of attachments included in your archives. • Memory transfer packages with larger source and output limits. Packages still have length limits. For a large archive, narrow the scope and create separate packages. Importing Gemini In Google Takeout, select My Activity > Gemini Apps and export an HTML archive in ZIP format. Arcora imports prompt activities from this format. Gems-only exports, scheduled tasks, and other Gemini export formats are not supported. What can be recovered depends on the original export. Prompts without a text response are kept without inventing a reply. Activities with unclear conversation membership are saved separately. Attachments are matched only to referenced local files inside the archive; remote content is not downloaded and file ownership is not guessed. Import notices explain these limitations. Later partial Gemini imports preserve history already imported. Arcora is an independent archive tool, not an official client of the supported AI services.

Verdict
The clearest difference is in-app purchases: markru at none against Arcora's 1. Arcora's advantage is iOS requirement (17.0 vs 27.0). On price, update cadence, ads and device support there is nothing between them.
