Beyond a Default Notes App
Most phones ship with a basic notes app that can barely display a code file, let alone help you edit one. Here's what changes with Simple Text Editor.

Frequently Asked Questions
Is Simple Text Editor free to download?
Yes. Simple Text Editor (SwiftWrite) is free to download on Google Play for Android. No account is required for core file editing.
What file types can it open?
It opens any text-based file — including Java, Python, JSON, XML, and plain text documents — directly, with no conversion needed first.
Do the AI features work offline?
No. Core editing, saving, and file management work fully offline, but AI tools like Document Chat, Natural Language to Code, and Grammar Check need an internet connection.
Does it back up files to the cloud?
Optionally, yes. Google Drive Sync backs up your files to your own Google Drive account in the background. It isn't required — everything also works with files stored locally on your device.
Can I edit code files without a laptop?
Yes. Simple Text Editor is built for exactly this — opening, editing, and getting AI help with Java, Python, JSON, and XML files directly on your phone, including code completion, an on-device compiler, and a JSON validator.
Does changing the editor's text color affect the original file?
No. Custom background and text colors are editor-level only, purely visual, and never change the original file's content or formatting.
Does Simple Text Editor have a dark mode?
Yes. Switch between Dark Mode and Light Mode from the editor's theme settings, along with custom background and text colors.
Can I track to-do items inside the app?
Yes. Simple Text Editor includes a built-in to-do list so you can track tasks alongside your notes and code without switching to a separate app.
