Japanese living in Toronto (prob temporary)

founder, engineer supavec, PenelopeAI SupaboxAI (acq.)

(tokyo/toronto)
as Japanese i really do hope the tech community in Japan will thrive with the impact of ppl like @danabra.mov

btw i do recommend Fukuoka for a long-term stay Dan

It’s a moderately sized city, and the airport is very close, so you can easily get to Tokyo when u need

I made a free Chat with PDF app — you may think "oh, another chat with pdf app!?"

Yes you're right.

but I built it with Supavec (oss RAG platform) to inject PDF data to AI.

and you know what?

you can do the same very easily!

I'm building an open-source alternative to Carbon .ai (RAG as a Service) — Supavec

Today is christmas eve but yeah i wanna post this.

After Carbon .ai's shutdown, I saw a clear need for a reliable, open-source RaaS solution.

what happened to me today:

hacking around for a couple of hours to build a free email marketing tool for influencer marketing.

i built an API to fetch YouTube video transcript with @LangChainAI

it worked fine on my local.

it always failed on Vercel.

saw a japan youtube debate on if the country should change due to rising tourist complaints.

this seems absurd to me.

every country should be allowed to remain unique - that's what creates global diversity.

if you don't like japan, move elsewhere.
if you don't like the us, move elsewhere.

Lost in a late-night coding session.

There's something magical about watching your product take shape line by line.

Feeling that rush of excitement again after so long.​​​​​​​​​​​​​​​​

After burning out, I forgot how I used to brainstorm and pick between ideas...lol

What's your process?​​​​​​​​​​​​​​​​

i read The Psychology of Money and it explains about a tail event.

meaning rare events have extreme outcomes.

that's how VCs make money.

A few big wins offset numerous investment failures.

this applies to founders as well.

most attempts fail, but just a few of them can produce enormous results

My greatest adventure was waiting at home...

Flying to Fukuoka ✈️

This will probably be my last nomad base within Japan for now.

tbh, being a digital nomad within Japan is absolutely stress-free and amazing.
