Copied text is rarely clean: duplicate lines, hard line breaks, HTML leftovers. OneTwo Text Editor fixes that with one tap, with 46 text transformations that run entirely on your device. No account, no subscription, no AI.
Four tools that run entirely in your browser. Nothing is sent to a server. The transformations are modeled on how the app behaves. The interface is simplified; the text detective and the quick start plan exist only on this page, not in the app.
Each tab has a typical problem. Pick a transformation in the toolbar: it works on your selection or, if nothing is selected, on the whole document. One undo takes it back. The demo applies the transformation immediately; the app first shows a dialog with “Cancel” and “Execute”.
Tip: try the hex view in the “mail-draft.txt” tab: the non-breaking space (C2 A0) and the zero-width character (E2 80 8B) are invisible in the text but easy to spot in hex. Your tabs stay in this browser.
Pick a tool, paste your text and see the result instantly. One click applies it to the editor.
Paste text and see what is inside: invisible characters, double spaces, HTML leftovers, non-breaking spaces. One click fixes each problem. The detective is a demo for this page only and not part of the app. In the app you reveal hidden characters with the hex view and remove them with the transformations.

Three typical cases. One click applies the transformations; they behave just like in the app.
Remove duplicate lines, unify bullet points
Join hyphenated words, remove unnecessary line breaks
Web content cleanup
A calm plain text editor with tools that clean up text in seconds.
Uppercase and lowercase, duplicate lines and blank lines, unified quotation marks, HTML leftovers and hard line breaks removed, and much more. Every transformation works on the selection or the whole document, and a single undo takes it back.
You decide which commands appear in the toolbar.
Six bundles such as “Copy-paste cleanup”, “Web content cleanup”, “Polish text” or “Compress text” chain several steps.
Shows the UTF-8 bytes of the text, on its own or next to the editor, read-only. Spot hidden characters such as non-breaking spaces, the byte sequences of umlauts and emoji, and line endings.
Find and replace inside a document, plus full-text search across the names and content of documents (content of locked documents excluded).
Several documents open at once in tabs, even after a restart.
Color tags, a filter bar and pinned documents. With iCloud, tags are the same on all devices.
Lock individual documents with Face ID, Touch ID or your device passcode. The lock hides the content in the app and in widgets; it does not encrypt the stored text.
Open, import and export text files, share and print with automatic page breaks; on the Mac also export as PDF. Widgets show pinned, recently edited and color-tag documents, plus “New Document”, also on the Mac.
Requirements: iOS 18 or later on iPhone, iPadOS 18 or later on iPad, macOS 15 or later on Mac.
The Mac version is a native app of its own, not an iPad port.
Through your private iCloud, documents and tags stay the same on iPhone, iPad and Mac. If another device changed the same document, the app reports the conflict with that device’s name and you decide: keep the local version or restore the cloud version (“Keep Local” or “Restore Cloud Version”). For illustration the demo shows both versions; in the app a prompt with the two choices appears instead. Try it:
Shopping Milk, eggs, bread
Shopping (Saturday) Milk, eggs, bread, cheese
You turn iCloud sync on and off per device (Settings › iCloud). Without iCloud the app works fully locally.
The app shows what was synced, what is still pending and whether there are conflicts or errors. At the press of a button it restarts the sync.
On first launch the app asks once whether to use iCloud.
The app needs no sign-in and has no ads.
No text leaves your device unless you turn on iCloud sync yourself. Then it lands in your private iCloud.
You lock private texts with Face ID, Touch ID or your device passcode. The lock is a privacy screen inside the app, not encryption. It is off by default and applies only to documents you lock yourself.
Everything else is in the privacy policy.
One-time · No subscription · No in-app purchases
You pay once and use the app on all devices without ongoing costs. The price in the App Store at launch applies.
OneTwo Text Editor for iPhone, iPad and Mac. Clean up.
Coming soon to the App StoreA calm plain text editor for iPhone, iPad and Mac with 46 text transformations, hex view, tabs and iCloud sync. It requires iOS 18, iPadOS 18 or macOS 15 (or later). On the Home Screen the app appears as “12 Texteditor”.

No. There is no account, no ads, no tracking and no AI, on purpose. No text leaves your device unless you turn on iCloud sync yourself.
It shows the UTF-8 bytes of the text, on its own or next to the editor, read-only. Spot hidden characters, the byte sequences of umlauts and emoji, and line endings.
Yes. You decide which of the 46 commands appear in the toolbar.
On iPhone, iPad and Mac you open and save text files and Markdown directly where they are stored (file mode), for example through “Open in” from the Files app or, on the Mac, through the Finder. The file is not copied into the library. “Import”, in contrast, creates a copy in the library, and “Export” writes a copy as a file.
If another device changed the same document, the app reports the conflict with the device name and you choose between “Keep Local” and “Restore Cloud Version”. You turn sync on or off per device, and without iCloud the app works fully locally.
OneTwo Text Editor is made for plain text, with cleanup tools and a hex view. OneTwo Markdown is an editor with a live preview for Markdown.
A one-time €2.99, one purchase for iPhone, iPad and Mac. There is no subscription and there are no in-app purchases. The price in the App Store at launch applies.
