Typing Speed

A Claude Code mod that measures how fast you type your prompts.

What you get

While you type, a live speedometer above the prompt:

⣾ 🏃  58 WPM ▰▰▰▰▰▰▱▱▱▱▱▱ ▂▃▅▆▅▇▆ Quick  ⏱ 12s  ✎ 142  🎯 98%

The icon, colour and label follow your speed: 🐢 Warming up, 🚶 Steady, 🏃 Quick, 🚀 Rocket, 🔥 On fire, ⚡ Lightning.

After you press Enter, a result card that counts up to your speed and celebrates a new personal best:

╭──────────────────────────────────────────────────────────╮
│ 🚀 72 WPM  ⌨  360 CPM  🎯 96%  ⏱ 23s  📝 27 words          │
│ ✦ New personal best! 68 → 72 WPM ✧                        │
╰──────────────────────────────────────────────────────────╯

Spell check, offline, in your system language. A misspelled word is underlined in red in the prompt once you have finished it, and when you pause, the band suggests fixes:

✗  yanlız → yalnız   recieve → receive

The card counts the typos of each prompt (✗ 2 typos or ✓ no typos).

/typing opens a stats pane: your average and best, accuracy, words and time typed, a bar chart of the last 7 days and a sparkline of your recent prompts. /typing reset clears everything.

How it measures

• WPM is the standard measure: typed characters ÷ 5 ÷ minutes.
• Pastes are not typing. An insertion of 8 or more characters at once (a paste, a history recall) is shown as pasted and left out.
• Thinking time is not typing. A pause of more than 5 seconds between keys is left out of the clock.
• Accuracy is 1 − deleted ÷ typed characters.
• Slash command names are not typing. In /btw why is this slow? only the arguments are measured; a bare command such as /clear is not measured at all.
• Prompts shorter than 10 typed characters and prompts you did not type are not measured.

Spell check

• Languages come from the system: macOS's preferred languages (defaults read -g AppleLanguages), Windows's display and input languages (PowerShell), and LANGUAGE, LC_ALL, LC_MESSAGES and LANG everywhere. English and Turkish dictionaries ship with the mod; English always loads, since prompts to a coding agent are full of it. A system language without a dictionary falls back to English.
• Left out: code spans and fences, paths, URLs, flags, file names, camelCase and snake_case identifiers, acronyms, words with digits, @mentions, slash command names, and the word you are still typing. A capitalized word followed by an apostrophe (Claude'un, İstanbul'da) counts as a name.
• /typing spell off turns it off and /typing spell on back on; the choice is kept. /typing spell says what it is checking with.
• /typing spell add <word> teaches it a word, /typing spell remove <word> forgets one.
• It runs on nspell with the Hunspell dictionaries of wooorm/dictionaries, all bundled: no network and no service. The dictionaries load in the background in about a second when a session starts.
• The Turkish dictionary does not know every suffix chain, so some long correct words (kitaplıklarımızdan) are underlined; add the ones you use with /typing spell add.

Stats are kept in the mod's own store: all time, the last 30 days and your last 30 prompts.

Install

Requires Claude Code v2.1.287 or later.

claude plugin marketplace add borabiricik/claude-mods
claude plugin install typing-speed@borabiricik-mods

Or inside a session: /plugin install typing-speed --marketplace borabiricik/claude-mods. Run /reload-plugins if a session was already open.

The band and pane draw in the terminal and in the Desktop app's Code tab.

What it can reach

A mod runs with your permissions, so check before you install one. This mod reads the clock, keeps its numbers in its own store, registers /typing and draws in the interface. For spell check it also reads its own dictionary files, reads the OS, LANGUAGE, LC_ALL, LC_MESSAGES and LANG environment variables, and runs one command when a session starts to learn the system languages (defaults read -g AppleLanguages, or powershell.exe on Windows). With spell check off it does none of that. It writes no files and does not use the network. To verify it yourself:

claude plugin validate ./plugins/typing-speed

Develop

claude --plugin-dir ./plugins/typing-speed   # load it for one session
claude plugin test ./plugins/typing-speed    # run the tests
node plugins/typing-speed/scripts/vendor-spell.mjs   # re-vendor nspell and the dictionaries

A hooks module cannot import npm packages and each module file is capped at 1 MiB, so scripts/vendor-spell.mjs bundles nspell into hooks/vendor/nspell.js and cuts each dictionary into chunks under dictionaries/, which the mod reads at run time. The dictionaries keep their own licenses (dictionaries/*/license).
