What is Letter Frequency Word-Start Counter Online?

This agent answers a simple but oddly hard-to-find question: how many English words begin with a given letter, and what share of the vocabulary does that represent? Name any letters and it returns a clean, copyable line for each one with the count and percentage. It also handles the documented command words from the original tool and can go a step further by counting word starts in text you paste yourself.

Key Features

Full A–Z reference table. Every lowercase English letter returns a word-start count and percentage share, formatted as a tab-separated line you can paste into a spreadsheet.
Command lookups. Asking for highest returns the top-letter statistics line; asking for siteoriginal returns the source article link.
Your own text, counted. Paste a paragraph and ask for word-start counts, and the agent tallies how many words in that text begin with each letter, with totals.
Sorting on request. Ask for results ordered by count, by percentage, or alphabetically.
Case handling you can see. Uppercase letters are matched to their lowercase reference entries, and the agent says so rather than guessing silently.

How to Use

Type the letters you want, separated by spaces or commas — for example a e s z — or paste a block of text and ask for word-start counts.
Add an optional instruction such as "sort by count" or "tab-separated only" if you want a specific layout.
Copy the result block. If you need a different order or a subset, just ask; the agent will re-render the same data.

Example Use Cases

Checking a letter frequency word-start counter for a quiz. Ask for s p c and get the three lines with counts and percentages to compare.
Counting word starts in a spelling list. Paste a vocabulary list and ask how many words begin with each letter; useful for teachers building phonics exercises.
Comparing letters for a writing project. Ask which letters have the highest word-start share and get a ranked list rather than a single canned answer.

A quick before/after: input a returns a 16869 7.11%; input highest returns s 25333 10.6%.

Tips for Best Results

Say whether you want the fixed reference table or a count of your own pasted text — the two give different numbers.
If you paste text, mention whether hyphenated words and numbers should count as words.
Ask for tab-separated output if you plan to paste into a spreadsheet.

FAQ

What input format does it accept? Plain text: single letters, space- or comma-separated letters, command words, or a pasted block of text for counting. There is no file upload.

How accurate are the numbers? The A–Z counts and percentages are fixed reference values carried over from the original tool's table; they are not live corpus statistics. Counts from your own pasted text are computed exactly from that text.

How is this different from a fixed substitution page? This agent returns the fixed reference lines on request but can also compute counts from text you supply and sort or filter the results.

Does it translate languages? No. It is a letter-frequency reference and counter, not a translator.
