Free calculators to help homebuyers understand their offer before submitting.
u/Offer-Buildr · Reddit
I built a free suite of home offer calculators because I felt that most mortgage calculators answer the wrong question I started and run a small free tool called "Offer Buildr" that helps homebuyers understand an offer before their agent writes it.

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
