Like many people, I needed a quick way to create QR codes. Most tools I found were cluttered, filled with ads, or locked useful features behind paywalls.
When I built Android apps, some of my apps will not run properly if Android phones does not have supported some features. Some of them crashes. An ideas comes out:
Most AI tools make you upload files into a chat, generate text, then manually move the result back into Word or PowerPoint.
I built Rework OS to remove that handoff. Open it in Chrome or Edge, choose a project folder, and ask AI to create a report or presentation from the notes, PDFs, spreadsheets, and documents already inside. The editable output is saved back to that folder.
No desktop app or Office plugin. New accounts get 200 free AI credits.
We re building Agino - a new way for people and AI agents to collaborate in the same communication space.
Most agents today still live as isolated tools.They may be powerful, but they rarely become part of how people actually talk, share, and work together.
On initial steps of developing web product, I don't know if product's idea is accepted by users or not. With my past experience, on these steps, saving money as much as possible but on order hand being ready to pay for better service with less effort in changing code base. I choose following hosting solution:
Front Gateway:
o The web which user access directly (or front-end)
o I use free hosting of InfinityFree.com . Free account has some technical limitation but provider provides premium package for $7 / month. The limitation of free account is bandwidth, JavaScript injection. So I make a util functions to get web results from back-end. When I move to later steps, I can buy premium account, then change util functions only, and the site will run faster without any limitation any more.
Bridge:
o HTTP tunel which help I publish back-end website to Internet from Android device on local network
o I use free account of Pinggy.io. Free account has limitation of non-continuous connection but provider provide premium package to remove limitation.
Back End:
o The web provide API to access database
o I use my free Android device to host this back-end. Because I don't use 3G/4G/5G, so
_ In USA, I buy smartphone from network provider, remove SIM card and use Wi-Fi only. It is very cheap, only ~ $35 - $45 with (3GB - 4GB RAM phone)
_ In Vietnam, the smartphone is much expensive but it is around $110 for (6GB RAM phone)
