An online notepad
and developer tools.
Every note lives at a URL you choose, saves as you type, and opens for anyone you send the link to. Alongside it, a task list and the small developer tools you reach for daily.

Tools that stay in your browser
JSON, Base64, JWT, regex and hashes all run locally. Nothing you paste is sent anywhere.
Built to stay out of your way
txtnode started as a personal scratchpad and grew into a small set of tools worth sharing. No clutter, no upsells, no accounts you're forced to create. Just a place to think and get things done.
Why people use txtnode as their everyday notepad
txtnode is a distraction-free notepad for capturing ideas, running daily checklists, and reaching for quick utilities without leaving the tab. It skips the clutter of a full word processor so you can start typing the moment the page loads, whether you're a developer, a writer, or just someone who thinks better on a blank page.
The editor supports rich text and markdown, so structuring documentation or formatting a code snippet takes seconds. There is no cap on how many notes you keep, and the light, uncluttered layout is easy on the eyes for long writing sessions.
Alongside notes, txtnode bundles a set of browser-based utilities including a JSON Formatter, UUID Generator, and Password Generator. Everything you type into these tools is processed locally in your browser, so no payload ever touches our servers.
Notes and tasks save as you type and live at the address you chose, so anyone you send the link to can open the same page. That also means anyone who finds the link can read it, so keep private things out.
Common questions
Everything people usually ask before diving in.
Is txtnode really free?
Yes. Notes, tasks, and every developer tool are free to use, with no hidden tiers or paywalls.
How is my data handled?
Everything is sent over an encrypted connection. Notes and tasks are stored against the URL you choose, and anyone who visits that URL can read or edit them, so keep anything sensitive out of them. The developer tools run entirely in your browser and send nothing to us.
Ready when you are
No setup, no waiting. Open a blank note or pick a tool and get straight to work.
