--- ✨ PRO-LEVEL ORGANIZATION ---
LIGHTNING-FAST BULK OPERATIONS (THE FAB) Stop right-clicking items one by one. Markd's Floating Action Bar lets you manage bookmarks at scale. Select 50 links and route them to a new folder instantly. Select a dozen folders to bulk-rename them (Find & Replace, Add Prefix/Suffix), or mass-delete empty folders with a single click.
FLUID DRAG & DROP WORKSPACE Built for heavy lifting. Markd features smooth edge-scrolling, spring-loaded folders that pop open when you hover over them, and instant demote/promote mechanics to build your ideal hierarchy effortlessly.
FIND ANYTHING INSTANTLY Never lose a link again. Use the Global Search to instantly find bookmarks by title or URL, or use smart local filters inside any folder to narrow down hundreds of links to exactly what you need as you type.
A BEAUTIFUL, CONTEXT-AWARE UI Enjoy a stunning interface that supports System, Light, and Dark modes. Smart visual highlights track your recent moves, and color-coded statuses let you see exactly what is happening in your workspace at a glance.
--- 🧹 DEEP CLEANING & MAINTENANCE ---
BROKEN LINK SCANNER Websites die over time. Markd includes a lightning-fast scanner that detects dead links (404s) and DNS failures across your folders, allowing you to easily sweep them into a dedicated "Broken Links" graveyard.
FLATTEN DEEP FOLDERS Markd enforces a clean, easy-to-read 2-level hierarchy. If you have messy, deeply nested folders (e.g., Recipes > Desserts > Cakes), Markd will automatically detect them and offer 1-click "Flattening Proposals" to compress them into a clean workspace.
--- 🧠 EFFORTLESS AI AUTO-SORTING ---
When you have hundreds of unsorted bookmarks, let the AI take over. Markd can read webpage content and automatically route links to the perfect folder.
--- 🛟 UNMATCHED SAFETY ---
THE "UNDO" TIME MACHINE Made a massive mistake? Markd remembers your last 50 actions. One click seamlessly rolls back massive bulk moves or accidental deletions. NATIVE CHROME SYNC Markd isn't a closed ecosystem. Everything you build directly mirrors to your native Chrome bookmarks. Uninstall Markd tomorrow, and your beautifully organized folders stay perfectly intact. PROTECTED FOLDERS Lock sensitive folders (like "Taxes"). Markd will physically secure them so they are completely ignored by the AI and protected from accidental deletion.
--- 💎 FREEMIUM VS. PREMIUM ---
Markd uses a generous Freemium model.
Note: Markd requires a Google Account to securely link your device to your subscription, and an internet connection to perform website validation and ping cloud AI services.
--- 💬 A NOTE FROM THE DEVELOPER ---
Markd was built with aggressive error-handling and extensive safeguards — including the "Undo" time machine and strict physical sync checks — to ensure your bookmarks are always safe.
However, building a tool that perfectly bridges complex AI models, massive data trees, and live browser storage is a massive undertaking. As an independently developed application, it is possible that despite thorough testing, you may encounter a rare edge case or a minor bug.
Your data safety is the number one priority. If the app ever detects something it doesn't understand, it is designed to halt the operation and ask you to "Sync" rather than guess and make a mistake. If you do encounter unexpected behavior, please reach out with feedback! Your reports directly help improve the tool for everyone.
