Watch your text shift styles live. The first 20,000 characters are previewed; copy any result straight to the clipboard.

Math ↔ Capital

Smart Digits: real numbers like 2024, 0300-1234567 and 100% survive reverse conversion — only letters that were actually converted flip back.

Future Style

Case & Code Formats

Code formats treat any mix of spaces, dashes and underscores as word boundaries — perfect for variables and filenames.

Fancy Styles — 14 one-way Unicode styles

Fancy styles convert letters and digits into decorative Unicode — they paste anywhere: bios, chats, games. They are one-way by design, and every change still lands in your undo timeline.

Toolbox

Find & replace, line tools and text cleaners

Find & Replace

Match case type to search

The match counter updates live as you type. Replacing lands in your undo timeline like any other change.

Developer Utilities — encode, decode, format

Encoding runs 100% locally — nothing leaves your device. Invalid JSON or URLs are rejected safely, and every result is undoable.

Line Tools — one click, whole text

Everything here is undoable — press Ctrl+Z if a tool does something unexpected.

Emoji Studio

Per-line emoji power tools

Nothing yet — your text will appear here.

Emoji — end of EVERY line

Add appends your emoji to the end of every line. Remove strips all emojis — keycaps, flags, ZWJ families and skin tones included — while normal text like arrows and the copyright symbol stays safe.

Export

Copy, paste or download your result

Nothing yet — your text will appear here.

Output

Download name follows your loaded file (file_converted.txt).

Share Link — text travels inside the URL

Your text is base64-encoded into the link fragment itself — no server, no shortener, no tracking. Perfect for chat apps. For very long texts, use Download instead.

The story and the machinery

What is TypeShift?

TypeShift is an offline text-styling studio — it shifts your writing between Math (K3S3 H0), Capital, Future glyphs and emoji-decorated styles in one click. It is the successor of the Math Typ Converter project, rebuilt as a SaaS-style workspace with undo history, autosave and Smart Digit protection. Everything runs locally in your browser: no account, no server, no tracking. Version 1.1 adds 14 fancy Unicode styles, a toolbox with find & replace and line tools, a live insights dashboard, dark and light themes with accent colors, share links that carry your text inside the URL, timeline import/export and full installable-PWA support.

Smart DigitsDigit-run analysis keeps real numbers intact during reverse conversion.

100-step UndoEvery action is labeled and time-stamped — jump anywhere in the timeline.

AutosaveText persists in localStorage; close the tab, come back, continue.

Private by designNo uploads, no network calls for your data — files never leave your device.

14 Fancy StylesBold, script, fraktur, double-struck, circled, small caps and more — one click each.

ToolboxFind & replace, sorting, dedupe, shuffle, renumber and case tools — all undoable.

Smart Digit Rules

Rule 1Digit run contains any non-convertible digit (1,2,5,6,7,8) → kept as a real number

Rule 2Run starts with 0 and has 3+ digits (phone numbers) → kept as a real number

Rule 3Otherwise the run converts back to letters, with case inferred from nearby letters
