Built Different.
Not Just Another Text Expander.
Most snippet tools are slow electron wrappers, break inside modern web apps, or charge $144/year to harvest your keystrokes. Shortcut Helper is engineered from first principles: 0ms in-memory Chrome text snippets engine, native virtual DOM compatibility, and airtight local privacy.
Instant Keystroke Replacement (Zero Cursor Stutter)
Traditional cloud-based snippet apps make remote network calls that cause an annoying 180–350ms cursor lag. Shortcut Helper evaluates in-memory regular expressions inside your local browser memory (chrome.storage.local) for instant 0ms expansion before the next screen frame paints.
In-line Live Math Engine
Calculate expressions directly inside any email, chat message, or document without opening a calculator app or switching windows.
eval()
React & Vue State Synchronized
Ordinary snippet extensions break in React, Vue, or Angular because the Virtual DOM wipes out inserted text on the very next keystroke.
input.value directly → Virtual DOM resets & wipes text!
InputEvents!
Preserves Native Undo Stack
Never get trapped by an accidental expansion. Shortcut Helper preserves the browser's native mutation stack so pressing Undo cleanly restores your trigger.
Preserves exact cursor position & document history.
Complex Emojis & Unicode Safe
Naive snippet tools chop multi-codepoint flags and skin tones in half. Shortcut Helper uses standard grapheme boundary clustering.
Zero character corruption on multi-byte codepoints.
Works in Every Web App & Editor You Use
Engineered to operate seamlessly across standard HTML <input>, <textarea>, and complex contenteditable rich text editors without configuration.
100% Local Sandbox
Your private keystrokes and sensitive shortcuts never leave your computer. Zero background keyloggers, zero telemetry trackers, and zero analytics beacons.
How Much Time Are You Losing to Repetitive Typing?
Every repetitive email signature, greeting, support reply, and code template adds up. Calculate your personal monthly time and keystrokes reclaimed with Shortcut Helper.
Other Extensions Charge $40 to $144/Year.
Shortcut Helper is 100% Free & Open Source.
No pricing tiers, no credit card traps, and no “upgrade when you scale” trickery. We believe fast, private text expansion should be accessible to every student, developer, and professional for free.
