Show HN: VerusCite, a tool to check for hallucinations in academic articles https://ift.tt/E3jbRgW

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 < https://veruscite-data.com/ >, and can see the benchmark for metrics and some description of the methodology at < https://github.com/apwheele/veruscite-data >. If you want to check out the approximate UI without signing up (at least the output), can see some examples: https://ift.tt/Lxn0fVB... https://ift.tt/gvek80R... https://ift.tt/TVrx4sE... 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/uf8j0Ph August 4, 2026 at 11:00PM

Show HN: Freqcast, an Android radio player that finds streams from a website URL https://ift.tt/rEO8lnU

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/qRicn3d August 4, 2026 at 03:05AM
