Questions & Answers

As answered by people managing regular expressions 101 and txtnode.

What makes your product unique?

txtnode's answer:

Most note apps make you install something or sign up before you can write. txtnode starts at the address bar: type txtnode.com/notes/ followed by any name and you are already writing. The note saves as you type, and anyone with the link can open it. The same site also has free developer tools and browser games, so the small things you reach for during a work day live in one tab.

Why should a person choose your product over its competitors?

txtnode's answer:

It is the fastest way to get text down and share it. There is no account, no app and no setup, and you can sign in later to keep everything in one place. Compared with Pastebin or Rentry, notes stay editable and save while you type. Compared with Notion or Evernote, there is nothing to learn. Most of the developer tools also run right in your browser.

What's the story behind your product?

txtnode's answer:

I built txtnode while studying for my BCA. My classmates and I used notepad.pw every day to share text and code, but it kept getting in the way. Pages were slow to load, notes could show up in Google and other search engines, which was a real privacy worry, and the ads were everywhere.

So I built the notepad I wanted to use: one that opens instantly, keeps notes out of search engines, and stays out of your way while you share text and code. It has grown since then with task lists, developer tools and games, but the idea has not changed. Open a link and start typing.

How would you describe the primary audience of your product?

txtnode's answer:

Anyone who needs to write something down and share it fast. Students pass notes and code between lab computers and phones. Developers use the JSON, JWT, regex, Base64, hash and cron tools in daily work. Teams, HR and small businesses share meeting notes, checklists and quick updates through a link, without asking anyone to install an app or make an account. Writers and planners keep drafts and to-do lists open in one tab.

Which are the primary technologies used for building your product?

txtnode's answer:

Next.js and React with Tailwind CSS on the front end, Node.js with Express on the back end, MongoDB for data, Redis for caching and limits, Socket.IO for live updates, and Firebase Authentication for sign-in. It all runs in Docker.
