New resources, browser tools and creative updates: day 18

Day 18 pulls together the most useful things we've shipped across the rest of the site. Every directory listing still links straight to its original source, and the new browser tools run locally without uploading your files.

The latest directory resources

Looking for the ten directory resources in this batch, from Web Dev Resources to Skills.sh? They're all covered in the day 17 roundup. Link: https://bestproductivityresources.com/articles/new-resources-and-updates-day-17

New tools you can use right here

Split PDF now lets you pull out every page or set 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 work the same privacy-first way: everything happens on your device, and the result is yours to download.

Fresh prompts, images and visual guides

The AI prompts collection now has a reusable prompt for getting clear step-by-step explanations, from the absolute basics right up to advanced ideas.

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

And the latest visual guides 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 to play with

The home page now has website and mobile app design collections, along with the exact prompts behind them. It also features Pizza Split, an interactive 3D pizza explorer made from a single GPT-6 Astra prompt, with a demo you can play with.

An easier way to browse

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

Everything in this roundup is live now. Start with one tool that fixes a problem you have today, then come back to the directory when you need the next one.
