Auto typer for Windows, Mac & Linux

What is an auto typer?

An auto typer is software that types text into a target application for you. You feed it the text (usually by pasting from the clipboard or loading a snippet), pick a target window, and the auto typer sends real OS-level keystrokes to whatever application has focus. The target app receives the characters exactly as if a person typed them.

The difference between an auto typer and a clipboard paste is timing. Paste delivers every character instantly in one event; an auto typer delivers one character per keystroke event at a rate you control. That makes the difference in applications that block paste, sanitize pasted text, or treat instant arrival as suspicious.

What makes a good auto typer?

• Adjustable speed — fixed-speed auto typers look obviously mechanical. The WPM range should span slow (20 WPM) to faster than real typists (250+ WPM).
• Human timing variation — humans don't type at constant intervals. A good auto typer produces bursts of fast keystrokes separated by pauses at punctuation and paragraph boundaries.
• Optional typos with correction — perfectly clean output at high speed is a giveaway. Realistic tools make occasional adjacent-key typos and backspace-correct them.
• Works across apps — an auto typer that only works in one target (the browser, a specific editor) is limited. Real keystrokes work everywhere.
• Cross-platform — Windows has the most options, Mac/Linux fewer. Matters if you work across platforms.

Auto typer for Windows

copypaster runs natively on Windows 10+ and is the straightforward pick for users who want a dedicated auto typer without writing scripts. The alternatives:

• AutoHotkey — free, open source, not a dedicated auto typer — it's a scripting language. You write AHK scripts to produce typing behavior. Powerful but requires setup. See full comparison.
• Murgee Auto Typer — dedicated auto typer, free tier with limits, $11 paid.
• AutoSofted Auto Typer — free, very basic, limited WPM control.
• PhraseExpress — text expander with some auto-type features, free for personal.

copypaster's niche among these is realistic timing, high WPM range (250 WPM cap beats most), and cross-platform reach.

Auto typer for Mac

The Mac auto-typer ecosystem is thinner because AutoHotkey doesn't run there. Your options:

• copypaster — native on Apple Silicon (M1/M2/M3/M4) and Intel, purpose-built for typing text into any application.
• Keyboard Maestro — paid (~$36), a full macro/automation suite. Typing is one of many features.
• Hammerspoon — free, Lua-scripted. Need to write the typing macro yourself.
• BetterTouchTool — paid, gesture and shortcut focused. Can do typing via custom actions.

If you just want to get text typed into an application on your Mac without writing scripts or paying for a full automation suite, copypaster is the shortest path.

Auto typer for Linux

copypaster ships as an AppImage + .deb for Linux. Alternatives are mostly DIY: xdotool (command-line keystroke sender), AutoKey (Python scripting), or custom shell scripts with xdotool type. None of these offer human-timing realism out of the box.

How do I use copypaster as an auto typer?

1. Download and install (7-day free trial, no credit card).
2. A floating pill appears at the top of your screen — always on top, stays out of your way.
3. Paste or type the text you want auto-typed into the pill.
4. Set WPM (default 65 WPM, range 20-250).
5. Optionally toggle realism settings (typos on/off, code mode for indentation).
6. Click into your target application — any editor, form, chat window, terminal, game.
7. Hit play. A 3-2-1 countdown gives you time to position the cursor; then the typing begins.
8. Pause, resume, or stop anytime from the pill. Progress bar and ETA are shown live.

What can you use an auto typer for?

• Screencasts and tutorials — code and text appearing naturally on video instead of as a paste-jump. Details.
• Live coding demos — present prepared code at a readable pace without typos. Details.
• Sales and product demos — fill forms with realistic sample data on live calls. Details.
• Accessibility / RSI relief — reduce keystroke load for long-form text entry. Details.
• Form-filling — type canned responses into systems that reject clipboard paste. Details.
• Humanize AI text — deliver AI-drafted writing as natural typing. Details.

How realistic is the typing?

The engine models typing as a LogNormal distribution of keystroke intervals (sigma=0.22 at the 65 WPM reference) with burst sizes of 3-15 words separated by pauses at paragraph (1.5-4s), sentence (0.8-2.5s), and clause (0.3-1s) boundaries. Adjacent-key typos happen at 40% of all typo events with backspace corrections, matching observed human error patterns. Speed drifts ±3% every 15-40 characters. At 250 WPM the realism features scale down automatically via `(65/wpm)²` so the output stays plausibly human rather than robotic.
