New resources, browser tools and creative updates: day 18

Day 18 brings together the most useful additions shipped across the rest of the site. Every directory listing still links directly to its original source, while the new browser tools run locally without uploading your files.

The newest directory resources

The ten directory resources in this batch, from Web Dev Resources to Skills.sh, are covered in the day 17 roundup. Link: https://bestproductivityresources.com/articles/new-resources-and-updates-day-17

New tools you can use here

Split PDF now lets you extract every page or create custom page ranges such as 1-3, 4-6 and 7. The file stays in your browser, nothing is uploaded or stored, and each result downloads as a new PDF. Link: https://bestproductivityresources.com/split-pdf

The existing Merge PDF and Personal Card Builder tools use the same privacy-first approach: the work happens on your device and the result is yours to download.

New prompts, images and visual guides

The AI prompts collection now includes a reusable prompt for getting clear step-by-step explanations, from the absolute basics through advanced ideas.

The AI images collection gained a functional-minimalist Maurya Empire wallpaper and a cinematic editorial collage-style YouTube thumbnail, both with the original prompts and model details.

Recent visual guides now cover Claude Fable 5.1, Google AI tools, new Grok tips, ChatGPT Images prompts and the September 2026 Apple event.

New design and AI experiments

The home page now includes website and mobile app design collections with the exact prompts used. It also features Pizza Split, an interactive 3D pizza explorer created from a single GPT-6 Astra prompt, with a playable demonstration.

A clearer way to browse

Long collections now start with a focused selection and reveal the rest through a See more control. Sponsored positions are consistently numbered 1 to 5 and 6 to 10 across desktop and mobile, while remaining separate from editorial directory rankings.

Everything in this roundup is live now. Start with one tool that solves a current problem, then return to the directory when you need the next one.
