Show HN: Rowboat – Open-source, local-first alternative to Claude Desktophttps://github.com/rowboatlabs/rowboatClaude’s desktop app is brilliant, but for our own daily work we kept wanting it to be less like a chat app and more like a full-fledged work app. Rowboat is our attempt at that, including the ability to build your own work surfaces inside Rowboat (more below).Our repo is https://github.com/rowboatlabs/rowboat, and there’s a demo video here: https://www.youtube.com/watch?v=et5yQABJ3xIIn a previous startup, we built a deep-learning product for enterprise support reps, including teams supporting P&G brands. Models took live notes, suggested replies, and recommended actions while support reps were on calls or handling emails. One lesson stuck with us: it's not enough for the AI to be right, the help has to show up where the work is happening.So we added what we came to call “work surfaces”: dedicated areas for email, meetings, notes, browser, and parallel coding, where the assistant can help inside the workflow itself rather than only through chat:- Email client: Rowboat has a simple emaiJul 7, 2026 4:10 PM

Show HN: hnsubstacks – Browse only Substacks submitted to HNhttps://hnsubstacks.com/I made an HN clone that lists only Substacks posted here.- Why? Over the years, I've discovered some great blogs here, so I thought it would be nice to have a filter for them.- Why only Substacks then and not blogs more generally? Because it's easy to query for "substack.com" in the public HN Algolia API (see below). Plus, hnblogs was already taken :)- What about substacks on custom domains then? At the bottom of the page there is a form to submit a custom domain. The site attempts to auto-validate that it is a Substack. If that fails, it is marked for manual review (which I'll do every once in a while). Approved ones will be included in the results.- How? I use HN's Algolia API to fetch substack stories by searching for "substack.com" in the url. I do this via a CloudFlare worker that has 3 separate cron triggers: (1) fetches new stories every 10 minutes and saves them in a KV store. (2) runs 2 minutes after the first, computes hot stories from new ones by simulating HN's score algoriJul 7, 2026 2:31 PM

Show HN: Fast, native Mac file manager (filters, fuzzy find, 9 MB, no Electron)https://whimfiles.comMy Downloads folder had been left unkept for a really long time and cleaning it up using Finder was quite cumbersome. So I started creating a simple app to help me filter out and delete or move the files in the folder.It started out very basic and the filtering options genuinely helped me clean out the Downloads folder, then as I thought of more features I would like to see in a file manager I started to add them. Some of the features are:- Fuzzy go to folder/file where you only need to write a few letters of a full path, get suggestions and can jump to the correct path instantly - Hover over a file to preview an image or PDF without opening it - Dual-pane view and tabs that remember selected filters - Command palette to find actions fast - Batch rename (with regex support and presets for common operations), image conversion (HEIC/WebP/AVIF to JPG/PNG), zip creation - Bookmarks, Quick Look, single-click open, keyboard controlAnd many other small quality of life features.I used Claude CJul 7, 2026 8:12 AM

Webb reveals millions of stars in nearby galaxyhttps://www.esa.int/Science_Exploration/Space_Science/Webb/Webb_reveals_millions_of_stars_in_nearby_galaxyIn new images from the NASA/ESA/CSA James Webb Space Telescope to celebrate its fourth science anniversary, a familiar galaxy transforms into something far richer, and far more complex, than ever seen before. Webb’s unprecedented sensitivity across near- and mid-infrared wavelengths cuts through the thick lanes of dust that obscure Centaurus A’s centre in visible light, showing a densely packed tapestry of individual stars and an active, everchanging galaxy. These images mark four years of better-than-anticipated performance and successful science operations for the most powerful space telescope in history.Jul 6, 2026 4:00 PM

Show HN: Riley – Content That Sounds Like You, Not Like AIhttps://rileywrites.aiWorking for a US company with several, very different, lines of business taught me how difficult it is to post on social media consistently and keeping the essence of each brand in all posts. Standard AI tools helped me get the first draft, but that was it. I would spend hours editing the output to make it sound a bit more like me, but in the end this was more time-consuming than starting from a blank page. Tired of choosing between consistency and maintaining the brand’s essence and my voice, I built Riley. My goal was to teach AI how I sound and the essence of each brand to remove endless prompts and constant tweaking, keep creative momentum, and make content creation a smooth and enjoyable process. Riley learns from previous content you’ve written to generate pieces that sounds like you, not like AI. You can import examples (LinkedIn posts, website copy, social media, etc.), define context with @context-pills for background, audience, and style, and refine with feedback and commentsJul 1, 2026 1:20 PM

Show HN: Gotaper – A minimalist, journal-inspired race planner for athleteshttps://gotaper.app/Lately I've been planning on running my first 100 miler and been struggling with organizing everything around the race. Been back and forth between google docs, notes, spreadsheets and AI agents. So in the middle of that, and a long run, though about creating a kind of journaling app for taking notes about the race and everything about it and it got interesting. So here is the first kind of working version. I would love some brutally honest feedback: - What do you think? - What is the clunkiest part of your current race-week planning workflow? - Does the journal-style layout give you more data control than just a spreadsheet? - What feature would make you actually drop your current setup for this?Jun 28, 2026 8:18 PM
