Products that do what Nedagram – Transfer Text Over Sound, when internet isn't available does
I’ve created Nedagram that I think it's ready but needs extensive testing before announcing it: https://nedagram.com ## Problem statement: - during Iran internet shutdown, the government cut off phone lines and mobiles (no text or calls). Gradually they opened up landlines and then phones, but still texting/SMS was down with no real internet. - There were still ways to connect through proxies, vpns, DNS tunnels, etc. However, people had no way to send each other VPN config files or proxy urls/passwords/etc (they needed to call and read them over the phone) ##…

Hello all, This is my second year of working on a project[1] with the goal of browsing the web, on an Android smartphone, without reliance on Wi-Fi or mobile data. While this concept might seem aimless, my goal was to provide a way for people in areas with limited, expensive, or censored cellular internet access a way to view the web in a basic format. I finished work on a basic client-server model last year[2], and this year, I implemented a new pseudo-distributed peer-to-peer model that allows any TxtNet Browser user to use their own smartphone to run a background server service that…

A few years ago, right after high school, I decided to try to make a simultaneous translation app for Android as a side project, it took longer than expected (about 2 years) and I had to make a lot of compromises (I had to use Google's API and therefore make users use a developer key because at the time there were no free solutions for speech recognition and translation that had good quality). At the end of university, I decided to pick it up again and finally, using OpenAi's Whisper for speech recognition and Meta's NLLB for translation (with both running locally on the phone), I managed to…

If you text 8145594701, it will send back an image with the prompt you specified. Currently only US numbers can send/receive texts because Twilio. Sorry to the rest of the planet! I think this will likely fall over but I figured this would be a cool little thing to demo. I removed the NSFW filter so be mindful of your prompts! I don't persist numbers and there is no linkages being saved between the original text message and the generated images.

This is just a small thing I coded to help me see my entire convo history in beautiful markdown, in Obsidian (my note-taking app). [Link to Github repo](https://github.com/mohamed-chs/chatgpt-history-export-to-md). The Python script helps you to convert conversations extracted from ChatGPT (ZIP export all your data, sent by Openai) into neatly formatted Markdown files. Also adds YAML metadata headers and includes Code interpreter (Advanced data analysis) intput / output code. Feel free to fork the repo and implement your own improvements, I feel like there's alot…

Hi HN, I built [PinSend](https://pinsend.app) — a free web app for instantly sharing text between devices, using a simple 6-character PIN. - No login, no account, no install. - Peer-to-peer WebRTC transfer (no server relay, no cloud). - Cross-platform: works on any modern browser. I built PinSend for myself while developing web apps—I was always copying ngrok links and sending error logs between my laptop and mobile devices. I wanted a frictionless, instant way to move links and text between anything. *Demo:* 1. Open https://pinsend.app on your phone & laptop 2. Paste or…

After switching to 100% Linux a couple of years ago there was basically only one thing I missed about macOS and that was what Apple calls "Continuity". It's where you get texts, notifications, clipboard sync, file transfer (to/from) the iPhone from the Mac desktop. Especially that thing where OTP codes via text autofilled into the browser form I was waiting on. It took about 4 months of work: - reverse-engineering Apple/iOS Bluetooth behavior - MAP / OBEX - Bluetooth LE + Wi-Fi working together - iMessage through the iPhone's own cellular/iMessage stack - iOS app, Linux…

Machato is a tiny ChatGPT client that supports all basic features, and more ! I was frustrated with other native implementations that focused on quick access but didn't give easy access to a history of what has been said. Since ChatGPT is a learning tool for me, I'm always ruffling through past conversations. The client supports markdown rendering as well as LaTeX. Feel free to try it out ! For those who see this thread early, you can use the promo code EARLY_BIRD to get a free lifetime license. Let me know if some aspects can be improved or if there are features you'd like to see…

Video demonstration: https://youtu.be/bJFa5HOmhl4 I created a demo involving ChatGPT, OpenAI's Whisper running on-device for speech-to-text (because why not?), and ARKit. By defining a custom JavaScript environment with JavaScriptCore and describing it to ChatGPT, I was able to get it to produce functioning scripts that instantiate and manipulate 3D objects. Sketchfab is used to import 3D assets on the fly. Google Poly had a much better catalog of assets for this sort of thing but sadly, it's no longer available. The README.md describes how it all works but the gist of it is…

I created a SMS based chat application that connects two people to chat (aka SMS roulette). I've opened up some invites for HN. Signup with your hacker news handle with (hn) so that you know when you are chatting with another HN'er. http://textslide.com/hn Feedback is always welcome.

Hi, I have published a mobile app to have coffee chat with HN users. There was already a guy who made a website for this, but I wanted to do it in mobile to practice WebRTC(technology behind the audio chat) and have some fun. I haven't spent too much time in terms of the general functionality as a HN client but can upgrade it if there are enough users enjoying the app. You can download the apps via the links below; IOS: https://apps.apple.com/tr/app/betternews-coffee-chat/id65047... Android: As you might have known, Android requires the app to be tested in a…

This interactive demo explores how a website can load and function while you're in airplane mode — even if you've never visited it before. It requires official Google Chrome and does not work on iOS devices (iPhone/iPad). Spoiler alert: For the best experience, try the demo before reading the explanation below. You can launch it by clicking the post title at the top of this page. The demo uses SXG (Signed Exchanges), a web standard that allows Google to prefetch entire pages from search results. This means that when you click a result, the page can open even if you're offline — because…

Hi HN, I’d like to share a side project I recently finished: Speech & Audio To Text, a small iOS utility to transcribe voice messages from apps like WhatsApp, Telegram, and Voice Memos — fully offline and without sending any data to the cloud. The motivation was personal. I often receive voice notes when I can't listen to them — during meetings, while commuting on noisy trains, or when I don’t want to disturb others. I used to rely on an app that handled this well, until it moved to a subscription model and started requiring constant internet access. I wanted something that would: - Work…

I built CallSky as a simple alternative for international calling after Microsoft shut down Skype earlier this month. The app lets you make calls to landlines and cell phones worldwide starting at $0.01/minute with a pay-as-you-go model. I noticed that while Teams replaced Skype's video/chat conferencing, it doesn't offer the same affordable PSTN calling that many people relied on. WhatsApp and other messaging apps don't solve this - whether you're an expat calling the IRS for taxes, reaching elderly family members who don't use smartphones, or contacting people in areas with…

How does it work? Chatbang works by scraping ChatGPT's website. It opens ChatGPT on a headless session when you execute Chatbang and take your prompt and paste it in ChatGPT's prompt area and execute that prompt, then it waits for the response and copies it as a markdown format and then render it in the terminal.

Hi everyone, after months of hard-working, I'm glad to have something to show HN. It's an iOS app to help you directly capture and intercept HTTP/HTTPS Traffic from your iPhone/iPad with ease. It's suitable for any developers who would debug iOS without needing a computer. You can also share all traffic to Proxyman macOS via AirDrop for better previewing. - Please join a beta in TestFlight (iOS 14+): https://testflight.apple.com/join/nQ69eb35 - How it works if you don't have any devices: https://www.youtube.com/watch?v=UpzpoTN8efM&feature=youtu.be…

We're back with another ShowHN! When we launched, you could text Jarvis AI using regular SMS messages from your phone. Since launching 3 weeks ago[1], we've introduced two new channels for using ChatGPT. Now you can use ChatGPT over SMS text message, iMessage for Apple-enabled devices, and via Email. It is super interesting to forward an email to Jarvis AI and see its thoughts on your email thread. It can help you brainstorm or it can suggest a reply to previous emails. 10 messages free forever, more volume is free over iMessage and Email for a limited time (until the HN hug of death!). You…
