BizPlannerAI▲293Hey HN, I’m Alex, an indie hacker and digital nomad. Since 2013, I've started a couple of dozen startups (most of them died at the idea stage) and applied to VCs, incubators, and accelerators. They all required a business plan. As a tech guy, I struggle even with writing documentation for my code, so writing business plans was always a huge issue. I tried doing it myself, and I even hired freelancers (which was very expensive for me at that time). Everything changed when ChatGPT was released. I built an AI business plan generator so every tech person can now easily write a business plan and…

Hi HN, I built a tiny tool because I couldn’t find a clean, distraction-free monthly planner that: 1. shows a clean monthly task view 2. doesn’t require an account 3. doesn’t sync or store anything online 4. works offline 5. is printable 6. and keeps a minimal, distraction-free aesthetic So I made https://printcalendar.top/ — a minimal monthly task planner. It’s intentionally simple. No logins, no integrations, no dashboards. Just a small tool for people who want structure without clutter.

Hey Hacker News! To test implementing AI (and paywalls tbh) in software for the first time, I made this simple calendar creator (no mail address required) that lets a person create a calendar based on his needs and availability and export it to his calendar app, pdf or receive a daily newsletter with his daily tasks (and more). After wrestling with different models (f.e. with huggingface) and encountering different problems, I decided to use ChatGPT's models, tune them a little and see how the result works out. ChatGPT's low price enables me to give users the opportunity to create calendars…

Hey HN! Ryan here (co-founder of YC-backed Muzz). I’m now building Onin, an end-to-end encrypted calendar and chat app that makes organising your personal and social life simple and secure. I’ve been building technology businesses for 10+ years and have witnessed the reoccurring problem that digital calendars were built for companies, not people. They feel cold, transactional, and anti-social — not the thing of dreams for planning your personal life. They also lack the security we now come to expect from consumer products. Onin is the first calendar to be fully E2EE, protecting not just your…

Hello HN, Over the last year we've been building snote.app, a Privacy focused, End-to-End Encrypted alternative to Notion. You can write, plan, collaborate and get organized - it allows you to take notes, store files, add tasks, manage projects & more. Whether you're working solo or in a team. We are hoping to use this post as an opportunity to collect feedback from fellow hackers. If there's anything we can do better, please let us know

I'm a solo dev. A few years ago, I got addicted to Reddit. Spent months in that loop. Being a programmer, I thought I'd be clever. Redirected Reddit's domain to nowhere in my DNS file. Worked great until I'd just... open the file and undo it 20 minutes later. So I made it irreversible. Locked the DNS file so it can't be edited unless I boot my Mac in safe mode. And if I do that, there's a script that instantly locks it again. Haven't used Reddit since last year. Problem solved, right? Wrong. I just replaced Reddit with Twitch and YouTube. Started keeping streams running in the background…
