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 (free trial — 5 pastes, 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.
