    Think interactive grep for text files, PDFs, DOCXs, etc, but word/token based instead of regex and line based, so you can search across lines easily. Docfd aims to provide good UX via integration with common text editors and PDF viewers, so you can jump directly to a search result with a single key press. --- I originally wrote this tool to help me dig through text/markdown notes, since very often I want to search for a phrase of sorts that may span across multiple lines, but constructing the corresponding multiline regex is a bit painful (especially painful if I want to account…

    Hi! I'm Marcell, and I'm working on FetchFox (https://fetchfoxai.com). It's a Chrome extension that lets you use AI to scrape any website for any data. I'd love to get your feedback. Here's a quick demo showing how you can use it to scrape leads from an auto dealer directory. What's cool is that it scrapes non-uniform pages, which is quite hard to do with "traditional" scrapers: https://youtu.be/wPbyPSFsqzA A little background: I've written lots and lots of scrapers over the last 10+ years. They're fun to write when they work, but the internet has changed in ways…

    I created an add-on for Google Sheets called Flookup, and it comes both as a free version and a VERY AFFORDABLE paid version. At its core, Flookup is a fuzzy matching add-on that helps you manage text that is less than a 100% match. Beyond that it can be used to: 1. Search for and match data regardless of whether it contains typos. 2. Highlight and delete duplicates duplicates even if the data has mismatched text. 3. Calculate the percentage similarity between strings. 4. Extract unique values from any column based on percentage similarity. 5. Sum and find the average of numbers based on…

    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:…

    We've been trying to evaluate web scraping companies, but when you look at their benchmarks, you can't verify anything, and they mostly exist to prove the company is successful. They put somewhere between 98% and 100% because they pick their own urls, define success their own way, and don't publish the harness. We also saw companies like scrapfly astroturf websites like scrapeway and call them independent. So, we built an open source benchmark that we want to represent the frontier of web data. We're trying to look across all major anti-bot providers and industries, to build a comprehensive…

    Hey HN, I got tired of manually comparing two lists (think: emails, product SKUs, code, whatever) and built CompareLists.org to make it painless. You just paste your two lists, hit compare, and instantly see what’s unique to each list, what matches, and any duplicates. It handles thousands of lines, works right in your browser (no data leaves your device), and you can export results as CSV/TXT/JSON. There are options for case sensitivity, whitespace, and more. It’s free and there’s no signup. I’d love for you to try it out and let me know what you think—or if there’s a feature you…
