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.
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.
You don't need an account or an email address to get started. Notes, tasks, and drafts save automatically to your browser's local storage, which keeps your work available offline and visible to no one but you.
Everything people usually ask before diving in.
Yes. Notes, tasks, and every developer tool are free to use, with no hidden tiers or paywalls.
No. There are no accounts at all, so there is nothing to sign up for and no password to remember. Open a note and start writing.
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.
No account, no setup, no waiting. Open a blank note or pick a tool and get straight to work.
