Show HN: I built a 55K-word email marketing knowledge base and Claude Code skillI co-founded SmartrMail (email marketing SaaS, 12K ecommerce customers, acquired 2022). When I left, I no longer had access to the sending data I'd spent years learning from, billions of sent emails, deliverability patterns, things that actually move email engagementCos' I don't have this data anymore, I built the best thing I could to help with the email marketing I currently do:---my research processMultiple sprints across all major email marketing topics. The crawler pulled 908 sources: Litmus, Klaviyo, HubSpot, Campaign Monitor, and Salesforce annual reports; practitioner blogs; academic research; platform documentation; Reddit threads; Shopify forums; and community discussions on X. From those, I extracted 4,798 discrete insights. Every claim that made it into the guide has a source. Anything that was unsourced opinion got cut.That produced EMB v4: Over 80k words across 16 chapters. After two editorial passes, cutting duplicates, consolidating overlapping sections, removing anythi

Show HN: Clipthesis – free, local app to tag and search video across your drivesI'm a hobbyist video creator with a dumb problem: years of footage spread across multiple external drives with names like "C01456". Every time I sit down to edit, I waste too much time hunting for clips I know I shot but can't find.I tried the usual recommendations (NeoFinder, Lightroom, various DAM tools) but nothing fit how I actually work with video. The online alternatives seemed to charge an arm and a leg, which is hard to justify when you're not running a production studio.So I built a thing for a free Mac app that indexes all your drives into one searchable video library even when those drives aren't plugged in. What it actually does- Index any drive or folder — point it at your external drives and it catalogs every clip with thumbnails, metadata, duration, resolution, etc. - Tag + search — tag clips however you want (b-roll, drone, interview, whatever), then combine tags to find exactly what you need - Duplicate detection — content hashing finds the same clip across multiple dr

Launch HN: Sonarly (YC W26) – AI agent to triage and fix your production alertsHey HN, I am Dimittri and we’re building Sonarly (https://sonarly.com), an AI engineer for production. It connects to your observability tools like Sentry, Datadog, or user feedback channels, triages issues, and fixes them to cut your resolution time. Here's a demo: https://www.youtube.com/watch?v=rr3VHv0eRdw.Sonarly is really about removing the noise from production alerts by grouping duplicates and returning a root cause analysis to save time to on-call engineers and literally cut your MTTR.Before starting this company, my co-founder and I had a B2C app in edtech and had, some days, thousands of users using the app. We pushed several times a day, relying on user feedback. Then we set up Sentry, it was catching a lot of bugs, but we had up to 50 alerts a day. With 2 people it's a lot. We took a lot of time filtering the noise to find the real signal so we knew which bug to focus on.At the same time, we saw how important it is to fix a bug fast when it hits users. A bug means in the wo

Show HN: PolliticalScience – Anonymous daily polls with 24-hour windowsI have been building a Blazor WASM enterprise app for a few years now. I wanted a break from it and had an idea for a side project that had been in the back of my mind for a few years. A daily political poll where anyone can participate and privacy is a product, not a checkbox.This is how it works. One question per day about current events. Agree or Disagree. Each poll runs for 24 hours (midnight to midnight ET) and then close permanently. You do not need an account to vote. The main idea is to capture sentiment at a specific point in time, before the news cycle moves on and people's opinions drift.For this app, I tried to make privacy the point and not just a feature. I originally used a browser fingerprint for anonymous voting, but recently changed it to a simple first-party functional cookie. It uses a random string and the PollId to see if your browser had voted before. The server stores a hash of the cookie to check for duplicates while the poll is live, then deletes all hashes wh

Show HN: Sara – Markdown-based requirements traceability tool written in RustThroughout my career in embedded systems — automotive (ASPICE), medical, avionics, CMMI environments — I've seen teams struggle with the same problem: requirements traceability. The options were always frustrating:Expensive, heavy tools like DOORS that don't fit modern dev workflows JIRA-based workarounds that slow everything down and integrate poorly with codeSo I built SARA (Solution Architecture Requirements for Alignment): a CLI that treats architecture documents and requirements as a knowledge graph. The core idea: your requirements are too important to be locked in proprietary systems. SARA uses plain Markdown + YAML frontmatter, which means:Full Git workflows (branching, code review, versioning) No vendor lock-in — switch tools anytime, your data stays readable AI/LLM-ready format for automated analysisFeatures:Multi-repo support Traceability queries (upstream/downstream) Validation (broken refs, cycles, duplicates, orphans) Coverage reports and traceability matricesComing soon:

Show HN: Plagiarismremover.ai – plagiarism remover focused on formattingA while back I kept running into the same frustrating workflow: plagiarism checkers would flag chunks of my text (especially drafts touched by AI), but fixing those flags manually often meant rewriting sections in ways that lost meaning or tone.So I built PlagiarismRemover.AI - a web-based tool that helps remove duplicated or flagged content while keeping the original meaning and structure. It’s not trying to replace writing or detection tools, but rather to help with that in-between step where you want something that reads well and is original.The tool is simple: paste text, run it, and get back a cleaned version. There’s a free plan for casual use and affordable paid tiers if you need higher limits, and no complex setup or mandatory waiting for emails. I’m sharing it here to get feedback from folks who care about writing quality and originality — especially people who write a lot or work with AI-assisted drafts.I’m also curious: for those of you who deal with plagiarism flags, how do

I think I found a bug in amazon.comHN Admins should feel free to delete this thread if it's a duplicate or off-topic.Steps to reproduce:1. Visit amazon.com (Desktop site)2. Search for a book e.g. 'The Hobbit' and submit (you should arrive at the "list" Results page, not sure of a more accurate name for this view)3. From the 'list' Results view, click 'Add to cart' button for one of the results. (Note the right hand portion of the screen becomes a mini-cart widget, and the 'Add to cart' button becomes a remove/add selector for adding removing additional copies with a '1' in the center indicating the number of copies in your cart)4. Remove the item you just added from your cart using the mini-cart "trash"/remove icon, not the trash icon on the "main" view.5. Note that the mini-cart is updated accurately to reflect you no longer have the item in your cart, however, the "main" view still thinks you have 1 item in your cart.6. Attempt to add or remove additional items using the "main" view once again, note that you receive a

Show HN: PineCone – A bundler for splitting PineScript into multiple filesI built a module bundler for PineScript (TradingView's scripting language).The problem: TradingView doesn't support multi-file projects. As indicators grow complex, you end up with 1000+ line files that are painful to maintain.Pinecone lets you split code across multiple .pine files using import/export directives, then bundles everything into a single TradingView-compatible script.It handles automatic namespacing to prevent variable collisions between modules, deduplicates external library imports, and includes watch mode for development.Built with Python. Uses the pynescript library for AST parsing and manipulation. I had to work around some upstream parser bugs with generic type syntax, which was an interesting challenge.GitHub: https://github.com/claudianadalin/pineconeBlog post with more technical details: https://www.claudianadalin.com/blog/building-pineconeThis is a niche tool, but if you've ever built complex TradingView indicators, you know the pain.

Show HN: Epstein's emails reconstructed in a message-style UI (OCR and LLMs)This project reconstructs the Epstein email records from the recent U.S. House Oversight Committee releases using only public-domain documents (23,124 image files + 2,800 OCR text files).Most email pages contain only one real message, buried under layers of repeated headers/footers. I wanted to rebuild the conversations without all the surrounding noise.I used an OCR + vision-LLM pipeline to extract individual messages from the email screenshots, normalize senders/recipients, rebuild timestamps, detect duplicates, and map threads. The output is a structured SQLite database that runs client-side via SQL.js (WebAssembly).The repository includes the full extraction pipeline, data cleaning scripts, schema, limitations, and implementation notes. The interface is a lightweight PWA that displays the reconstructed messages in a phone-style UI, with links back to every original source image for verification.Live demo: https://epsteinsphone.orgAll source data is from the official public releases

Show HN: Fixing a single pointer bug unlocked 1M+ row JSON parsing on WindowsI've been building a cross-platform JSONL viewer app that handles multi-GB files. It worked perfectly on macOS (my development machine), but consistently crashed on Windows at exactly 2,650 KB. Here's the debugging journey and the tiny fix that made all the difference.The Problem- macOS: Handles 5GB+ files effortlessly - Windows: Crashes at 2,650 KB every time - Same codebase, cross-compiled from Mac Silicon to Windows using MinGWThe InvestigationAdded detailed logging to track execution. The crash happened during string interning after successfully parsing ~6,000 rows. Not during parsing, not during file I/O, but during the merge phase.The Root CauseMy StringPool class used std::unordered_map to deduplicate strings. The string_views pointed into a std::vector.When the vector grew and reallocated, all the string_view keys became dangling pointers. The hash map was full of invalid references.Why did it work on macOS? Different memory allocator behavior, different default stack sizes (8M

Show HN: BatchShots – In-browser batch editor for image and SEO optimizationMy aunt runs a small side business selling handmade figures, which means she takes a lot of photos. I became her photo editor, and the job was always the same: fix dark images, remove background clutter, find the best shot from a group of duplicates, and get them ready for her online store.The manual work was slow. It wasn't just photo editing, it was also getting the images ready for the web. I had to resize and compress them, then create SEO-friendly filenames (slugs) and product descriptions to help her store show up in search results.I started with Photoshop and Lightroom, but the process was slow. I tried open-source tools like GIMP and wrote my own scripts with ImageMagick, but it was still not fast or easy enough.

Show HN: An MCP that fetches code context from all your reposHey HN!One of the biggest limitations of tools like Cursor is that they only have context over the project you have open.We built this MCP to allow you to fetch code context from all of your repos. It uses Sourcebot under the hood, an open source code search tool that supports indexing thousands of repos from multiple platforms.The MCP server leverages Sourcebot's index to rapidly fetch relevant code snippets and inject it into your agents context. Some use cases this unlocks include:- Finding all references of an API across your companies repos to allow the agent to provide accurate usage examples - Finding existing libraries in your companies codebase for performing a task, so that you don't duplicate logic - Quickly finding where symbols implemented by separate repos are definedIf you have any questions or run into issues please let me know!

The icon will switch to a color of your choosing when you're visiting a page that is already in your Safari bookmarks (so no more creating accidental duplicate bookmarks). Also, you can see the exact folder(s) where that page is bookmarked when you click on the star icon (super handy if you have lots of folders). Additionally, I added a bookmark analysis feature, where you can create a report of all your duplicate bookmarks (so you can clean up duplicates).Bakckground: I am kind of a semi-retired veteran (worked at Amazon and Google before) and I have been using Mac systems for more than 20 years, and used all kinds of internet browsers, but mostly Chrome until last year.

Why SMB(NES) Preemptively Clear the Hidden 1UP Flag Before Mario Hits the Block?I'm analyzing the disassembled code (https://gist.github.com/1wErt3r/4048722) of _Super Mario Bros._ (NES) and came across some logic related to hidden 1UP mushrooms. While debugging the game alongside the code, I noticed something unexpected: the flag preventing *duplicate* 1UP collections isn't cleared *when Mario actually hits the hidden block*—it happens *earlier*.``` ; https://gist.github.com/1wErt3r/4048722#file-smbdis-asm-L4172Hidden1UpBlock: lda Hidden1UpFlag ;if flag not set, do not render object beq ExitDecBlock lda #$00 ;if set, init for the next one sta Hidden1UpFlag jmp BrickWithItem ;jump to code shared with unbreakable bricks ```For example, in World 1-1, this logic runs *when Mario reaches the position shown in the image below*, even though the hidden 1UP mushroom is still offscreen in the next frame. This means that if a beginner player gets killed by the two Goombas near this spot before reaching the hidden block, *they will permanently lose the chance to obtain the 1
