Show HN: Let your website visitors ask ChatGPT/Claude/Gemini about your product

Hey HN,I built a free widget that adds an "Ask AI About Us" button to your website. I think it's a great idea to let AI be your advocate. When a visitor clicks the AI icon, it opens the AI platform in a new tab with a pre-filled prompt.It's not a chatbot. There's no training data to maintain or conversation flows to design. It simply connects your site to the AI platforms that people already...

Haha "Stripe-no-webhooks library"

Library based on processing ... wait for it ... webhooks".

Good point! I don't understand why this link received so many points.

Show HN: RCS Composer – a visual editor that outputs RBM JSON

RCS Composer (rcscomposer.com) is a simple tool that allows you to receive an API payload for Google’s RCS endpoints (https://developers.google.com/business-communications/rcs-bu...).It lets you build messages like rich cards and carousels and then copy the generated JSON to use in your integration.Bonus: I added a quick reference list of carriers that support RCS on Apple devices.Would love...

Nice! I made something very similar, but with a focus on frequent daily use, means no clicking required, you can only use keys

Look at stringify.cc

Re:We got a $60k tax penalty for a zero-revenue side project on Monday November 10, 2025 @03:56PM (#45880822)
When we logged into the tax portal, only this amount was shown as to pay. Terrible UX.

In fact, the fine was actually what we paid (minimum tax + missed deadline + interest).

“Normal fine”: We just didn't expect you to be able to incorporate a company and if you miss the tax payment deadline, you will receive a fine 100 times higher than the cost of incorporating the company, no matter what.

But of course, I don't recommend our way. Don't do it. It was wrong. Pay your taxes. Fill out all the required documents.

Re:We got a $60k tax penalty for a zero-revenue side project on Monday November 10, 2025 @03:30PM (#45880551)
Good question. We have considered all options. But the company cannot be officially closed without paying all taxes/fines, etc.

At the same time, with a C corp, only the company itself is liable for taxes and fines, not its founders. If a company does not have sufficient funds, it cannot operate, and there is a process for automatically dissolving the company (after several years, if you have no outstanding obligations to third parties, no fraud intentions, etc.). We didn't want to do this and be left with an unpaid bill in our minds.

Our target market was US, so US company was the first and only choice.
Re:We got a $60k tax penalty for a zero-revenue side project on Monday November 10, 2025 @09:29AM (#45876365)
I agree, and I think we knew that even back then!

However, we thought that starting a company would motivate us because we would be "commited" and this would demonstrate to each other that we were serious about it, given that we all had other jobs. And to this day, I still think it has some meaning.

what is the difference?

Re:We got a $60k tax penalty for a zero-revenue side project on Monday November 10, 2025 @08:32AM (#45875844)
Well sure :) but we expected to pay a "normal" fine, not $60,000 right away. Especially since we had zero revenue. Today we would do many things differently...

We got a $60k tax penalty for a zero-revenue side project

In 2020, in the middle of COVID, a few friends and I decided that obviously the world needed another presentation tool.Our pain point was simple: we hated fighting with PowerPoint/Google Slides. We just wanted to write content and get nice slides without babysitting fonts, sizes, alignment, colors, and 19 different "Title + Subtitle" layouts that all somehow looked bad.So we built a prototype:...

Haha, I see people talking about slides everywhere, from specific moment in my life... that's when I started coding slidepicker.com!

Anyway, nice work! I created something similar for our product (a list of divs that switch visibility based on keyboard input).

Thanks! I can’t wait to read your feedback!

Haha, same! Which tools are you using or trying to use?

Personally, I hate having to edit slides in Google Slides or PowerPoint because everything can be moved! After every simple text edits, I have to change the position of every text element, and so on. Awesome functionality is missing from HTML and CSS: auto-aligning.The idea of converting Markdown to slides is not new. There are lots of tools that do it well.Unfortunately, libraries like...

Re:Nostr on Friday September 19, 2025 @04:11AM (#45299190)
Thank you! Exactly this "It is JSON with some fingerprinting/hashing send over Websocket" should be write there somewhere + put a link to the documentation and an example of how to use it. I don't want to watch an hour-long video.
Re:Nostr on Friday September 19, 2025 @03:45AM (#45298983)
I don't understand. Can someone explain it to me from a technical/IT perspective? Is it like HTTP or JSON, or like XMPP...?

"An open protocol with a chance of working" = ?huh? "Nostr doesn't subscribe to political ideals of "free speech"" = ???huh? "BEEP BOOP" ???wtf??

Please don't explain technical things as if you were talking to children. Explain them as if you were talking to a colleague sitting next to you. Talk to them as a person and as a professional.

Hi HN,

Last weekend, I wondered whether I could replace our clunky contact form with a WhatsApp chat. Forty-eight hours (and a lot of Claude Code prompts) later, OWA.link was live.

Stack (all edge-deployable): Cloudflare Workers KV for storage/DB React app link generator (most of the UI and functionality was generated by Claude Code). SimpleAnalytics was used for anonymous click stats.

Here's what you can test:

Try this link: https://owa.link/book-meeting

Click and answer to see WhatsApp open with a pre-filled message that includes your form data.

Alternatively, try this simplified version: https://openwa.link/plDumo

It's completely free if you're OK with sharing your analytics data (everyone can add "+" to the end of links to see the number of clicks, like bit.ly does).

Why share? I'm curious to know if this edge-only approach makes sense in the long term.

Is the AI actually useful? This is my first project that has been created entirely by AI (front end, back end, help guide and translations), and I think it's pretty awesome.

All feedback (technical, UX and business) is welcome! If people find it valuable, I’ll clean up the code and open-source the Worker next week so you can host it yourself.

Thanks for your attention, and happy hacking! :)

I really like it. Good job! Please keep it ad-free/tracking-free. It's very rare in recent years ... for the same reason I built stringify.cc in recent weeks - https://news.ycombinator.com/item?id=44386194
Nice. But why?

Show HN: I made a fast, offline-first developer toolkit with no ads or tracking

Hey HN,I was fed up with using online converters and generators. They were slow. They used server encoding. They were full of ads. Or they required cookie confirmation for simple tasks.Opening VS Code or Sublime with plugins was also slow.So, I built a simple, web-based toolkit called Stringify that I thought some of you might find useful. It started as a personal project with no aspirations to...
