Combine notes on an infinite canvas and export sequences as PDF pages.
@JonnyD · X
I'm happy to announce "Mash" A local first browser based app for compiling notes and ideas on an infinite canvas. Make as many notes as you want, drag and drop to "Mash" them by combining. Create "sequences" that allow you to export a pdf with each sticky as it's own page. Drop in PDF or DocX or images to easily browse the file and select your favorite clippings to a new canvas, and manipulate them or export them how you want to. Drop a GIF to get all the individual frames. Mash features a roster of cute food themed mascots because this is your infinite textual stove top. Pull in some ingredients, mash them together, stitch them together, arrange them into a flow chart, whatever you find useful, and then get out quickly. Mash is for the little moments that speed up work, and the spontaneous thoughts that inspire new directions. There is no fancy AI feature, no data collection, no login, just a utility for you. Free open source licence. Run it offline if you want

Fast diagonal and offset calculator for framing, layout, and construction.

Write the doc once → get a notebook, slide deck, canvas, or resume from the same source. No rewriting for every format.

Free, no signup: In this video you watch the whole thing get built and shipped — with AI — from a blank file to a live URL: the 3-question flow, the curation logic that makes it useful, the real bug that broke it on a real input (and the fix), and the 30-second deploy to Vercel. 🔥 WHAT IS THE AI STACK PICKER?

Mobile workspace for editing and previewing HTML/CSS/JS apps with AI integration.
u/heisenberg2995 · Reddit
I built a mobile workspace to edit and preview the HTML apps ChatGPT/Claude write for you. Hey everyone! I built VanillaPad , a mobile workspace for building simple HTML/CSS/JS projects. 👉 https://vanillapad.dev The idea came from something I kept running into. Sometimes I'd need a simple utility app or a quick landing page or to test a little game idea. Getting the initial code written was easy since I could just ask ChatGPT or Claude on my phone. The hard part came af
