Show HN: A Multiplayer Chatbot Imagine if ChatGPT thought you should meet someone it recently spoke with. I built this simple demo that keeps messages from other users in context, so it can suggest connections and stuff. You can modify the system prompt to decide what the whole point of this is. I’m looking for ideas! https://ift.tt/BXSrEYh March 11, 2025 at 11:08PM

Show HN: Chrome Extension for ChatGPT to organize conversations into folders https://ift.tt/mbySFQp

Show HN: Chrome Extension for ChatGPT to organize conversations into folders Hi HN, I'm Alex, a full-stack developer from Toronto, Canada. I recently built a Chrome extension that organizes ChatGPT conversations into folders, allowing users to sort and save important information for easy reference. The idea for this extension came from a friend who highlighted the lack of good (and affordable) ChatGPT organizers. Many existing tools were either low-quality or overpriced, so I decided to create one that was both reliable and accessible. I built the extension using plain JavaScript and developed a backend with Express to handle Google authentication. For storage, I used MongoDB, enabling all users with an account to save their folder structures and conversation data. Initially, I planned to charge $5 per month to cover costs since originally this extension was intended as a portfolio project addressing a real-world problem. However, just as I finished the main functionality and was about to implement payments, ChatGPT announced an official feature similar to one my extension was providing. Rather than continue competing in a market with an "official" solution, I decided to stop development. But I didn't want my work to go to waste, so I chose to release it for free, motivated by a desire to share it with the community. I made some changes to eliminate the backend. Now the extension stores all folder structures and content locally in Chrome storage. Luckily, I had some old code to reuse for this. The extension is now live on the Chrome Web Store. This project introduced me to a lot of new challenges with technologies I hadn’t used before, but I’m grateful for the experience and the skills I gained along the way. I hope you find it useful!

Riding the Rails: San Francisco Cable Car Stamps

Riding the Rails: San Francisco Cable Car Stamps
By Kelley Trahan

Evening shot of a cable car on Powell Street with passengers, February 29, 1968 San Francisco's iconic cable cars aren't just a beloved tourist attraction. They are a symbol of the city's unique history and ingenuity. And they’ve appeared on two United States postage stamps. Let's take a journey through the history of these tributes and see how they came to be. The first ride: the 1971 cable car stamp The first cable car stamp was released in 1971. It was an 8-cent historic preservation stamp honoring the San Francisco cable cars. It showed the cable car's charm and was a small tribute to the...

Show HN: I built a Figma plugin for quick data calculations https://ift.tt/tWdDjkA

Show HN: I built a Figma plugin for quick data calculations I lead design on a B2B SaaS product. It's quite data-heavy in places. Using placeholder content in data tables, checkout summaries and dashboards is a big no-no for us. It might seem like using random numbers saves time at first, but sooner or later there's documentation to write and plenty of clarifications to be made. It throws off customers during interviews – "hey, that's not really my sales target!". It confuses stakeholders at review time– "what's this data point supposed to be?" I built a Figma calculator plugin for my team so that they spend less time doing mental maths. It calculates sums, differences averages and percentages, and makes it easy to use real-looking data in designs. https://ift.tt/H1mRWyv March 10, 2025 at 07:11PM

Show HN: I built a free SVG Web site https://ift.tt/wEtsrZ9

Show HN: I built a free SVG Web site This has been an experiment to see if I could create everything using scripts and AI. If AI couldn't do it I'd get it to create the code such as API calls and so on. This websvg.com site was completely created using these AI tools. Including the DNS being applied, the Cloudflare Pages were automatically set up and the the web site was a Svelte 5 application generated by v0.dev and Cursor. Every image was generated in Midjourney and converted to SVG. I have now taken all of these scripts and can create a similar landing or directory site in less than a minute, provided I have the data. Anyway it's been fun. https://websvg.com/ March 10, 2025 at 01:50AM
