Show HN: Alphabet Soup, a multiplayer game, build the longest word to win I've been working on a simple multiplayer word game called Alphabet Soup. It's a bit like NYT Spelling Bee, except it's multiplayer and only your best (longest) word counts toward your score. So, instead of trying to find as many words as possible, the game is more about finding one unusually good word. You can play with friends in a private match, or, you can join a public Arena match to play against other players who are online. If no one else is around, you'll be matched with a bot. The game works well with just 2 players, but, also works with bigger groups since the game isn't turn-based. https://alphabetsoup.club August 10, 2026 at 01:45AM

Show HN: Validate your idea, know what to charge, and how to get first users I made an idea validation tool that can quickly adjust or kill off weak ideas. The big difference between Nell and any other validation tool is it compares your idea with real passed and failed examples, calculates TAM, overall buying sentiment, and 14 more important pointers that VCs value. It then also creates the most confident go to market plans to get initial users. My goal with Nell is to compress the research that takes more than a month into a few minutes so that early stage founders can spend time on polishing, preparing strong investor pitches, and executing GTM. How it works: Once you’re in. Just paste your idea and you will get a 14+ pointer diligence report having - validation of the problem you are trying to solve, funding potential based on past similar ventures, demand signals, willingness to pay, pricing research, market size, revenue ceiling, and other critical metrics.

Show HN: VerusCite, a tool to check for hallucinations in academic articles Hello HackerNews -- I have created an application that verifies citations. Main motivation is to make checking for hallucinated citations in academic papers simpler/faster. Can sign up for the tool at , and can see the benchmark for metrics and some description of the methodology at . If you want to check out the approximate UI without signing up (at least the output), can see some examples: https://ift.tt/1eHDXWx... https://ift.tt/qZ9dQ8A... https://ift.tt/NyBWDRu... There are many minor errors in citation lists (maybe on the order of 5%). So even if you were not worried about hallucinations, it is useful for editors. If you sign up I have attempted to make the UI as easy as possible for a human to review the output and make changes (there are definitely errors, see the github for estimates of error rates). So let me know what you think HN! https://ift.tt/q7U2ovl August 4, 2026 at 11:00PM

Show HN: Freqcast, an Android radio player that finds streams from a website URL Hi HN! Not every internet radio station is listed in a directory like Radio Browser. For a lot of them, the only way to actually listen is to dig the stream URL (.mp3/.aac/.m3u8) out of the station's website by hand — and that's before you even find a player that isn't full of ads or locked to its own catalog. Freqcast lets you paste the station's website instead of the stream URL directly. It first checks the Radio Browser catalog, then scans the website itself, discovers a playable stream, verifies that it works, and adds it to your library. In many cases, you never have to hunt for the URL yourself. No ads, no tracking, no account — everything lives locally in the app. Your station list can be exported as JSON, and imported from JSON, OPML, M3U, or PLS. No Play Store listing — grab the APK from Releases. F-Droid submission is in progress. Would genuinely love feedback! https://ift.tt/Qhu...

Show HN: Hacker News with AI stories filtered out Hi folks, I've noticed that a lot of people here seem exhausted by the amount of AI news on the front page. I shared hcker.news here a year ago and it has since gained a ton of filtering features, including a dedicated AI filter, so I figured I should tell more people about it. The filter works in three passes: 1. Known AI-related keywords and domains are filtered automatically. 2. An agent reviews the remaining articles and removes those it identifies as AI-related. 3. I make the call on uncertain cases. You can also exclude GitHub repos posted to HN that show signs of AI authorship. The filter checks: - Commit messages for agent attribution - Contributors for known coding agents - Repository files for agent instructions and configs No filter will be perfect, but this is as good as it gets. lmk what you think. Cheers. More links: Original Show HN: https://ift.tt/izNDpHk If you only want AI stories: https...
