I built a document translation app (docx, pptx, xlsx, etc.) that keeps the layout and translates better than Google Translate or DeepL. Still in free beta — would love for you to try it: kintoun.ai #indiehacking #translation #googletranslate #deepl

I kept seeing people spend days repeating tasks that could be done in seconds. Just automate them. Try tools like n8n, RPA, or AquaBlue.app (I'm the founder). You'll wonder why you didn't start sooner.

What do you think of this comment? "In B2B SaaS you don't sell the software, you sell your expertise in a specific domain and the responsability you take for owning that expertise." Source: news.ycombinator.com/item?id=468924…

Remember this? It's still working!

TIL that Google "recommends against using the same URL for multiple languages, such as serving both French and English versions on example.com/page.html based on user information." I have been doing this forever! I guess it's time to replace "/page?locale=en" with "/en/page".

Last day of 2025: just released the all-new Kintoun.ai (Word/Excel/PowerPoint document translator that preserves formatting and layout). #indiehacking

@firefox After trying Firefox on my phone and laptop various times through out the years, I'm convinced that it doesn't have any respect for user privacy. I'm done with it, for good.

This time the BROWSER (@firefox) ITSELF showed this pop-up. What a madness!

Almost every website throws endless pop-ups now, making the UX unbearable. Lately I feel like I'll end up self-hosting everything just so I can use my computer without interruptions.

Made a tiny tool that syncs the iTunes play history to Last.fm with sync notifications, too. github.com/felixding/retr… Apple Music's UI drove me insane, and every working iTunes scrobbler has basically died.

This is beyond disgusting. Shame on you @SuperhumanHQ

Translating a CJK PPTX to English (or vice versa) is tricky. Formatting is preserved, but slides often look off due to text density. How can I fix this on kintoun.ai?

My first customer of kintoun.ai from Germany! The translation must have been good, as he made a subsequent payment immediately. As the creator, the feeling of being useful to others is truly satisfying.

Added Vietnamese and Mongolian support to kintoun.ai. Switched to GPT-4.1 for now since it's about 2x faster than 5! Since some friends in China are using it too, Alipay and WeChat Pay support will be coming soon.

Improved Kintoun's translation reliability and added the ability to delete unpaid translations. Side note: more and more people are using Kintoun on ChatGPT. kintoun.ai

Hi @SlackHQ, should I clean up channels, unlock Business+, boost productivity, learn about AI, or maybe just check my new messages?

Spent a few hours adding image translations to kintoun.ai, only to find the current vision models still aren't up to the task. Guess I'll wait a bit longer.

The web becomes a complete shitshow if you block all pop-ups (e.g., using uBlock Origin). Most websites would stop working altogether in my rudimentary tests.
