Products that do what I made a Smart Calendar – E-Paper Based, Useful AI, Firmware Access does
Hi HN! My name is Harsh and I've made a Smart Calendar that lives on your desk and syncs with your favorite calendar and task apps. Inku was created to do three things: Be useful, be smart, and be joyful - and that's it. It's mostly a passive device meant to be in your work/home space and not whine for your attention. It started out as a personal project but eventually ended up doing a small alpha test after interest from friends and people on the internet - we’ve now gone all out with a crowdfunding campaign. The Inku Smart Calendar: Uses Spectra 6 spec E-Paper Connects to the major…

Napkinbook is a smart canvas for collaboration, sharing, and discovering insights. I think of it as a more computational version of Excalidraw or Miro: a flexible canvas where you can think, build, present, and collaborate without constantly moving between different tools. Since my first Show HN, I’ve added: * Much better mobile support * AI-assisted brainstorming * Presentation decks with animations * Shareable reports * Live collaboration * Actual Git history The goal is to make the canvas itself the workspace, rather than treating whiteboarding, presenting, reporting, and version history…

Care to share a screenshot and the 'killer feature' of any of your personal, self-built productivity tools? eg. I made my own calendar and money-tracker last year - there are no other users, it makes no money, I have no plans to make it public, but it holds my life together :) http://i.imgur.com/h2keJDg.png GREAT BECAUSE... it tells me how much I'm going to get paid this month. Absolutely no ulterior motive here (ie. I'm not canvassing opinions for a productivity app startup or anything), just interested.

Hi HN! We are 3 young entrepreneurs and we've created XNote, a smart writing set that bridges the gap between traditional note-taking and AI-powered digital organization. Simply put, XNote is a Smart Pen (real ink), Special Notebook (real paper), and a mobile app. Here's what it does: - Instantly digitizes handwritten notes to your phone or tablet - Allows you to chat with your notes using AI, making information retrieval effortless - Combines the tactile experience of writing with the power of digital search and organization Our journey so far: - Launched on Kickstarter in November 2023:…

I’m building Attagram: a small printer that lives in the kitchen and prints a daily paper digest for kids. The idea came from an emerging family dynamic I kept noticing. My daughters (A, 9 and J, 8) are becoming increasingly independent, but as parents, we hold an enormous amount of invisible state in our heads and phones: what day a project is due, who needs cleats, what's for lunch, which kid has library day, what chores need to happen before screens, how many days until the camping trip, what Grandma wanted them to know, what changed after school, etc. Kids live downstream of that system,…

I’ve always liked fast online tools for jotting notes or organizing thoughts — but most “productivity” sites either save data to the cloud, require sign-ups, or are full of distractions. So I built an online productivity tools website, a small collection of browser-based tools. It includes an online notepad where you can write and save notes right in your browser, a cornell notes tool available in more than 20 languages, and more coming soon like a pomodoro timer and a simple blank page for focused writing. Everything works entirely in-browser using localStorage — no accounts, no cloud sync,…

Almost one year ago I asked HN if anybody is interested to make a Web app to make reading and finding scientific papers smarter [http://news.ycombinator.com/item?id=1664648]. No one did, at least no one did what "I" think is the best way to approach this problem. A a few month ago I decided to do it myself.<p>Meet JournalClub iPad app (absolutely free), http://itunes.apple.com/us/app/journalclub/id443819334? I have a recommendation engine in the pipeline that I would introduce in the next update (hopefully in a month or so). I really appreciate any comments, feedbacks.

Hi HN, I did this project over the Labor Day weekend. My family runs off our shared Google Calendar. This project was to use a ESP32 and three-color e-ink display to create a wall-mounted daily updated calendar, weather and news dashboard for us to coordinate our lives.

Hey guys, I was really inspired when I saw the reception to HackerThings yesterday. We built an app over the course of a few weekends that we've been using personally but not had the time to promote, we're growing organically just via word of mouth & referrals currently. Thinng is a place to create visual lists of all the products you might want to buy, or want people to buy for you. So technically you can use it to create your own list of HackerThings or whatever you are into. Install our bookmarklet, use it when you're on a page with the product & save the image with a…

I'm trying to get the motivation up to actually finish building out a "real" product, and I found myself needing a "win" to keep my momentum up. So, I hacked out a little one sentence journal app last night. I experimented with a few UI things (e.g.., the autosaving of the sentence for today and so on), so it was a good learning experience also. You can check it out at: http://osod.im

Hey there HN! Happy to share a piece of my labor I've been working on for the past 6 months. The idea for the app came to me when I found out that taking notes in Telegram saved messages and private channels is pretty convenient, but it became a mess real quick. Imagine accidentally sending your to-do list to your boss? And there were no work-related stuff, haha So I decided to solve this pain point of mine by creating a little app, just as a side project. But then I lost my job due to a layoff, so I decided to triple down on my idea, polish it, and make it a SaaS in the hope of making it…

It's dead simple. There's no fancy interface. Basic features are gone. That's all on purpose. If you're like me, you're always writing down ideas on pieces of paper. My webapp is like that, but for the internet. Let me know if you find it useful.

My partner and I do a lot of planning around things like holidays and trips, which involves a mix of firm, tentative, and overlapping plans, and normal calendars are the wrong fidelity for that kind of planning. We often found ourselves drawing on top of screenshots of calendars with tools like Miro or even printing out calendars we could draw on. We're both product designers, and so we're used to working in low fidelity tools like Excalidraw and FigJam. We decided to try and make a low-fidelity equivalent for calendars, and built Walnut. It's just lines and stickies, with a few different…

Hello there! I hope you're doing well today! I wanted to share something with you. Recently I was on the hunt for the best way to journal daily. Well, I had this idea - what if I could feed all my daily entries to an AI (ChatGPT), and create a friendly, supportive character like Socrates or Simon Sinek? This way, I could ask any questions about my life and mental health, and get some amazing advice on how to improve myself! The results have been absolutely mind-blowing ! I even made a short GIF to show you how it works - check it out! - https://gifyu.com/image/SdHLH I've…

I've built an app that serves simple purpose of quickly collaborating on ideas and creating action items during meetings without barrier of signup and onboarding overload.
