Show HN: Watsn.ai – Scarily accurate lie detector https://bit.ly/48eeLc0

Show HN: Watsn.ai – Scarily accurate lie detector No signup required—just upload or record a video to verify its truthfulness. You can test it on anyone: internet clips, your significant other, or even yourself. I know there are tons of scammy 'lie detector' apps out there, but I built this using SOTA multimodal models in hopes of creating a genuine breakthrough in the space. It analyzes micro-expressions, voice patterns, and context. In my own testing (over 50 trials), it reached about 85% accuracy, which honestly felt a bit scary. It’s also fun to test on famous YouTube clips (like Obama talking about UFOs). I’d love to hear what you think and will be improving Watsn.ai every day based on your feedback! https://bit.ly/3K4hlbm December 2, 2025 at 04:46AM

Show HN: NeurIPS 2025 Poster Navigator I woke up Sunday morning ready to schedule my week at NeurIPS. To my immediate horror, the NeurIPS.cc poster sessions have 1k+ posters in a stupid little dropdown. So I built a little app to help navigate them by research area/keywords/etc. Built it in a few hours with codex, gemini-cli, and Claude code. Same stack that produced 50% of the papers at NeurIPS ;) Free to use, no signup. https://bit.ly/4pG8GL0 December 2, 2025 at 02:55AM

Show HN: Net RazorConsole – Build Interactive TUI with Razor and Spectre.Console https://bit.ly/4iurZVj

Show HN: Net RazorConsole – Build Interactive TUI with Razor and Spectre.Console Finally, after landing component preview support and moving the codebase under the RazorConsole org, we think it’s the right time to introduce RazorConsole to Hacker News. # RazorConsole RazorConsole is a library for building interactive terminal applications using Razor components, rendered through Spectre.Console. If you’ve used React Ink, the idea will feel familiar: a declarative component model that stays cleanly separated from your application logic. If you like how Blazor/Razor expresses UI but want to target the terminal, RazorConsole might be a good fit. # Highlights - Author terminal UI using familiar Razor/Component syntax - Render Razor components directly into Spectre.Console renderables - Keep your UI declarative and composable, similar to Blazor and React Ink # Links - GitHub: https://bit.ly/4po7zjm - Website: https://bit.ly/44vnIeA A special shout-out to Nick Chapsas, who created an excellent introduction video: https://www.youtube.com/watch?v=1C1gTRm7BB4 . His coverage brought a huge boost during RazorConsole’s cold-start phase, and we sincerely appreciate it. If you want a quick, clear overview of what the project does, his video is the perfect starting point. # What’s next - More interaction: mouse and scroll-wheel events - More layouts & styling: additional layout primitives (e.g., flex-like patterns), potential CSS-style syntax - More components: a component registry experience similar to shadcn https://bit.ly/4pG4vii December 2, 2025 at 02:20AM

Show HN: My pushback against ANPR carparks in the UK https://bit.ly/4anfcBZ

Show HN: My pushback against ANPR carparks in the UK In my area I have 8 ANPR car parks within a 10 min radius that are free to park in, but you need to remember to enter your registration plate if not you are hit with a £70+ fine. This is easy to forget for older people. People who are with the kids. ect ectt. so I have made an app that sends a push notification after you enter one.Its free. I will add pro features in the future to keep it alive and server costs. Im in the process of populating the car parks but users can still add there own in the local area if they want https://bit.ly/4pgf5wS December 1, 2025 at 10:19PM

Show HN: Tracktrip, Travel Expense Tracker Hello HN! I'm a European traveler, and during my last 6 months of travel I created an app to keep track of my expenses. I made it open-source and started to build a website and a documentation for other people to use it! It's a fairly simple PWA that you can install on mobile that can help you set a budget, keep track of expenses and analyse what you spend. Thanks for any feedback and keep traveling guys! https://bit.ly/48bgKOf November 30, 2025 at 10:29PM

Show HN: Real-time system that tracks how news spreads across 200k websites https://bit.ly/4alHJrG

Show HN: Real-time system that tracks how news spreads across 200k websites I built a system that monitors ~200,000 news RSS feeds in near real-time and clusters related articles to show how stories spread across the web. It uses Snowflake’s Arctic model for embeddings and HNSW for fast similarity search. Each “story cluster” shows who published first, how fast it propagated, and how the narrative evolved as more outlets picked it up. Would love feedback on the architecture, scaling approach, and any ways to make the clusters more accurate or useful.

Show HN: ClearHearAI-The Essential App for Hearing Impaired and Deaf Communities I built ClearHearAI to help hearing impaired and deaf people. It is a transcription app that provides context indicators (e.g. when questions are asked, urgent keywords are detected, conversation is happening). All audio processing happens entirely on your device - your voice never leaves your computer. Conversation transcripts are stored locally on the device. Any feedback welcomed. https://bit.ly/3M98WDZ November 29, 2025 at 11:31PM

Show HN: I built Magiclip – an all-in-one AI studio https://bit.ly/48pQWN9

Show HN: I built Magiclip – an all-in-one AI studio Hi HN I’ve been working on a tool I personally needed as someone who edits a lot of video content. The problem is simple: Modern video editing requires 8+ different tools, all slow, all noisy, all repetitive. Subtitles here. Audio cleanup there. Silence removal elsewhere. Upscaling in another tool. AI voice in a different one. A clip extractor somewhere else… So I built Magiclip.io — a single interface that automates the most boring parts of editing. What it does today Auto-subtitles (fast & accurate) Silence removal AI voice-over Audio enhancement Image upscaling Clip extraction from long videos Thumbnail generation Quick TikTok/Reels format conversion And more coming The idea isn’t to replace full editors. It’s to remove the friction of things we repeat 100 times. Upload → Magic → Download. No timeline, no project files, no complexity. Why I built it I edit content frequently, and the workflow felt unnecessarily painful. Magiclip is my attempt to reduce editing from hours to seconds by batching the most common tasks behind simple endpoints. What I’d love feedback on What other tasks should be automated? Anything in the UX that feels off or slow? Any feature you’d want exposed through an API?

Show HN: Yolodex – real-time customer enrichment API https://bit.ly/4p4Ydt1

Show HN: Yolodex – real-time customer enrichment API hey hn, i’ve been working on an api to make it easy to know who your customers are, i would love your feedback. what it does send an email address, the api returns a json profile built from public data, things like: name, country, age, occupation, company, social handles and interests. It’s a single endpoint (you can hit this endpoint without auth to get a demo of what it looks like): curl https://bit.ly/49HZ3qI \ --request POST \ --header 'Content-Type: application/json' \ --data '{"email": "john.smith@example.com"}' everyone gets 100 free, pricing is per _enriched profile_: 1 email ~ $0.03, but if i don’t find anything i wont charge you. why i built it / what’s different i once built open source intelligence tooling to investigate financial crime but for a recent project i needed to find out more about some customers, i tried apollo, clearbit, lusha, clay, etc but i found: 1. outdated data - the data about was out-of-date and misleading, emails didn’t work, etc 2. dubious data - i found lots of data like personal mobile numbers that i’m pretty sure no-one shared publicly or knowingly opted into being sold on 3. aggressive pricing - monthly/annual commitments, large gaps between plans, pay the same for empty profiles 4. painful setup - hard to find the right api, set it up, test it out etc i used knowledge from criminal investigations to build an api that uses some of the same research patterns and entity resolution to find standardized information about people that is: 1. real-time 2. public info only (osint) 3. transparent simple pricing 4. 1 min to setup what i’d love feedback on * speed : are responses fast enough? would you trade-off speed for better data coverage? * coverage : which fields will you use (or others you need)? * pricing : is the pricing model sane? * use-cases : what you need this type data for (i.e. example use cases)? * accuracy : any examples where i got it badly wrong? happy to answer technical questions in the thread and give more free credits to help anyone test https://bit.ly/3LVvGYd November 24, 2025 at 03:02PM
