  Diffnote – Browser-based document diff tool with no server uploadsFeb 2026 · diffnote.net · ▲5

  I built a web-based document comparison tool where all file parsing and diffing happens entirely in the browser. The idea came from watching non-technical coworkers struggle to compare document versions — manually reading two files side by side or fighting with Word's Track Changes. Technical details: PDF parsing via pdf.js, DOCX via mammoth.js — all client-side Diff engine: Google's diff-match-patch Line, word, and character-level comparison Next.js 15 + TypeScript, deployed on Vercel No files ever leave the browser. No signup required. Site: https://diffnote.net Product Hunt:…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
