Products that do what Dengen Shrine – A privacy-focused digital Shinto ritual does
Hi HN, I built "Dengen Shrine," a web-based experience of a traditional Japanese Shinto ritual. Key Features: Privacy by Design: Your "Kotodama" (messages/prayers) are never stored in any database. They exist only in the animation and vanish upon completion. No Login Required: You can experience the ritual instantly without an account. Digital Offering: For those who wish to support the project, I’ve integrated a "digital offering" (Osaisen) via Stripe. This is completely optional—you can experience the core ritual for free without any payment. It’s not a donation, but a paid digital…

Look, every journaling app out there wants you to organize things into folders and tags and templates. I just wanted to write something down every day. So I built this. One note per day. That's the whole deal. - Can't edit yesterday. What's done is done. Keeps you from fussing over old entries instead of writing today's. - Year view with dots showing which days you actually wrote. It's a streak chart. Works better than it should. - No signup required. Opens right up, stores everything locally in your browser. Optional cloud sync if you want it - E2E encrypted with AES-GCM, zero-knowledge,…

Hi everyone! This is my first HN and I’m very new to the scene. My name is Min from Bangkok. At first, I just want to create a dead man's switch for personal use and for fun. then, I think about information that self destruct like a spy movie. after that, I try to come up with the better version of Privnote or Bitwarden with self-destruct and some kind of censoring or blocking download ability. Somehow, end up with this product. :O Flashpaper is for sending any information that would be burned after reading (with counting down timer like Mission Impossible movie ! or after 24 hrs max if not…

Hi HN, I’m Linn, the creator of ToolKuai (https://toolkuai.com). Like many of you, I’ve always been wary of "free" online file converters. Most of them are black boxes: you upload your private documents or images to a remote server, and you have no idea where that data ends up or how it’s being used to train models. I wanted to build a suite of tools (Video/Image compressor, OCR, AI Background Remover) that runs entirely in the browser. No files ever leave your machine. The Tech Stack To make this performant enough to rival server-side processing, I leaned heavily into modern…

I'm a long time lurker that recently quit my job to work on my own projects, a lot due to the inspiration from Hacker News. Now I have published my first serious project, an app for learning how to write Japanese characters. It's the app I always wanted but couldn't find when I was studying. It tries to be simple to use, you just start the quiz and go with the flow. There's no need to plan and manage your studies, and it uses spaced repetition for better retention. There's a promo page with more details up at http://www.kanjibyhand.com. It's only for Android so far. The free version includes…

Once upon a time I watched Jim Jarmusch's Ghost Dog and fell in love with the theme, aesthetic, and philosophy. The underpinning text is the Hagakure: The Book of the Samurai, with which the 14-year-old me became obsessed. After briefly reigniting my interest when reading a book by Yukio Mishima, I had a hazy idea of an infinite-scrolling Hagakure. Wherever you are in the world, you can open the page and jump right in at the same point as everybody else. It's not much, but it was an idea that formed and I'm pleased to have executed it.

Hi HN, I got tired of having to register and having friends having to register accounts just for accepting a party or dinner invitation (also plenty of friends have left social media) so I coded a minimal, no-login event tool: https://yupno.com Dev-friendly stuff: Full REST API, async webhooks for RSVPs with Slack/Discord-adapted payloads. Auto-generates Ical, JSCalendar and JSON-LD. No auth, uses admin/user tokens in url. Should be possible connect to other stuff in fun ways. Free to use, no ads, no tracking. I just wanted a simple tool that respects my time and privacy.…

I built a symbolic dream interpretation engine that runs fully in the browser no AI, no backend, no cloud. Just vanilla JavaScript and a hand-mapped keyword system. It scans dream text, matches symbolic keywords to over 300 custom meanings, using deterministic logic. All data stays in localStorage no tracking, no server. Try it here: https://dino-nuggies45.github.io/Dream-Interpreter/ Built to explore subconscious patterns and emotional systems without machine learning. Feedback welcome!

Hi HN, I have been working on a new tool that was inspired by Vannevar Bush's memex and Luhmann's Zettelkasten. Having been a long time user of different tools, I got to the point where I decided to build my own. For the longest time I have been looking for something that puts association first, works as fast as the mind, and allows you to stay in flow state. Making building a second mind, playful and rewarding. If anyone is interested, I have added the link below. At this point I am slowly letting on the first users, and hoping to gather as much feedback as possible. The explore link on the…
