How much of it says nothing?

Paste any text. Fluff marks the filler, buzzwords, throat-clearing and repeats, scores it, and hands back the gist: only the lines that actually say something.

The score

Words that carry nothing.

Pleasantries, stock openers, buzzwords, hedges, vague claims and lines that repeat an earlier one all count as fluff. Facts, names, numbers and dates count as substance.

The gist

Your point, minus the padding.

Fluff keeps the lines that say something and trims phrases like “it’s important to note that” and “in order to”. Nothing is invented, so it stays in your voice.

Nothing leaves this tab.

The check runs on your device. Your last text stays in this browser until you clear it, and a shared link carries the text inside the link itself.

Common questions

Fluff scores how much of a text says nothing (filler, buzzwords, throat-clearing, repeats), marks every fluffy line, and hands back the gist: only the lines that say something. Runs in your browser, no account.

How do I know if my writing is full of fluff?

Paste it into Fluff. It strikes through sentences that carry no facts, names, numbers or dates and are mostly pleasantries, stock phrases or buzzwords, flags lines that repeat an earlier one, and gives a fluff score from 0 to 100.

What counts as fluff?

Throat-clearing ("I hope this email finds you well", "I wanted to reach out"), stock openers ("in today's fast-paced world"), padding ("it's important to note that", "at the end of the day"), buzzwords (leverage, synergy, robust, seamless, unlock), hedges and intensifiers (basically, very, could potentially), vague quantities (various, a number of, significant) and sentences that say the same thing twice.

What is the gist?

It is your text with only the sentences that say something, in your own words and order. Padding phrases are trimmed ("in order to" becomes "to"). Fluff does not summarize with AI and never adds words, so nothing is made up.

Is my text uploaded or stored?

No. On the website the check runs on your device and nothing is sent to a server. The optional API processes text in memory only to return a result and does not store it.

Is Fluff an AI detector?

No. Fluff does not guess who wrote a text. It measures how much of it says nothing, whether a person or a chatbot wrote it.

Can an AI assistant use Fluff?

Yes. There is a public JSON API (POST https://fluff.clawhard.com/api/v1/check with {"text": "..."}, see /openapi.json) and the tools fluff_check_text and fluff_gist_text on the Clawhard MCP server at https://mcp.clawhard.com/mcp. Results include a link that opens the text in Fluff.
