Updates

The homepage now leads with free ChatGPT Prompt Packs for work (role selector, variable highlighting, one-click copy). We shipped AI Detector, AI Resume, AI Presentation, Chat with PDF, a /tools hub for classic converters, four scene pack pages, and a visible /contact page. Trust routes including Contact stay on the AdSense deny list.

• Primary intent: role-based Prompt Packs—not bare “chatgpt prompts” or AI art/selfie packs.
• New routes: /ai-detector/, /ai-resume/, /ai-presentation/, /chat-with-pdf/, /tools/, /prompts/marketing|sales|teachers|real-estate/, /contact/.
• Classic tool URLs (PSD, PDF to image, Mermaid, etc.) remain unchanged and are listed under /tools/.
• TRUST_NO_ADS covers about, privacy-policy, terms-of-use, contact, updates, and non-whitelist paths (including 404).

We stopped injecting the Google AdSense loader on trust and legal routes (About, Privacy Policy, Terms of Use), Updates, and non-tool paths such as 404. Ads continue only on the home page and tool pages. The same pass expanded edge tool guides (merge images, Mermaid to PNG, PSD to PNG, Study With Me) and added more substantial Chinese copy so locale pages are not thin shells.

• Footer AdSense loader is gated by a pathname whitelist (home + sidebar tools). About, Privacy, Terms, Updates, and unknown/404 paths do not mount the pagead script.
• Privacy Policy already documents Advertising (Google AdSense), third-party ad cookies, Ads Settings, and industry opt-out links; that disclosure stays intact.
• Edge English guides and matching zh localization were expanded with tool-specific section titles and reordered blocks to reduce identical Privacy → Limitations → Related skeletons across every tool.
• robots.txt, Sitemap, ads.txt, and the /privacy → /privacy-policy redirect remain as previously shipped—this release does not roll those back.

Earlier the same day we fixed crawler self-redirects on robots.txt, added the AdSense advertising disclosure block to Privacy Policy (en/zh), thickened Image Splitter educational copy, and restored a descriptive title on the online MP3 player.

• robots.txt returns plain text with Sitemap: https://dk-js.com/sitemap.xml and no Location self-loop.
• Privacy Policy includes Advertising (Google AdSense) and Third-Party Ad Cookies with Ads Settings and aboutads.info choices.
• Image Splitter guide/use-case/privacy/limitation copy was expanded for AdSense content quality.
• MP3 player page title now names the tool intent instead of a bare site brand string.

We made MP3 player playback feel steadier while dragging the progress bar, and the browser tab now shows the current audio name so you can recognize what is playing at a glance.

• Dragging the progress bar is now much more precise, so you can jump to the exact part you want without the timeline bouncing around.
• The browser tab title now shows the current track name, which makes it easier to spot the audio in browser tabs and similar system-level views.
• We also kept the playback feedback smoother during seeking, so the player feels more responsive and less distracting.

Tightened the mobile navigation flow and unified the install/app title to DK-JS so home-screen installs match the product name used in the browser chrome.

• Mobile menu items now dismiss the sheet immediately when tapped, which reduces the awkward wait before the drawer closes.
• Install prompts and home screen titles now consistently use DK-JS.
• The mobile sidebar animation feels smoother and more polished on smaller viewports.

Mermaid to PNG and Mermaid to SVG gained optional diagram names so multiple flowcharts open in different tabs stay recognizable while you iterate on architecture notes.

• Optional diagram name field helps distinguish flowcharts across browser tabs.
• Export settings (theme, background, scale) remain client-side for the core download path.

Added Chinese locale routes (/zh/…) with real localized copy—not an English shell—and introduced Mermaid to PNG and Mermaid to SVG as first-class tools in the sidebar.

• Chinese pages use lang=zh-CN with hreflang en / zh-CN / x-default.
• Added Mermaid to PNG and Mermaid to SVG converters for documentation and slide workflows.
• Sidebar grouping (Mermaid, Image, PSD, Time, Focus, Audio, PDF) became the primary way to discover tools; the footer stays limited to About, Updates, Terms, and Privacy.

The early DK-JS catalog centered on PSD viewing/conversion, PDF page rasterization, image merge and split, playlist covers, stopwatch/timer, Study With Me, and a local MP3 player—each aimed at finishing a small job without installing desktop software for the basic path.

• PSD Viewer and PSD to PNG for quick Photoshop file checks and flat exports.
• PDF to Image for page previews; Merge Images and Image Splitter for collage and tile workflows.
• Study With Me pairs a focus stopwatch with optional YouTube or local companion video; Stopwatch and Timer cover lap timing and countdowns.
