Passive Voice Detector

Highlight sentences that likely use passive voice so you can decide whether to rewrite them.

What this tool does

Scans each sentence for a form of "to be" followed by a past participle and lists the sentences that match, with the share of passive sentences in the text.

Who should use it

Writers who prefer direct, active phrasing for tutorials and product copy.

How it works

The pattern is: am/is/are/was/were/be/been/being, optionally an adverb, then a word ending in -ed/-en or a common irregular participle (written, taken, made…).

How to use it

  1. Enter or paste text in the form.
  2. Use "Load example" if you want to see how input should look.
  3. Press the run button. Processing happens instantly in your browser.
  4. Review the result panel, then copy or download the output if the tool offers it. Use Reset to start over.

Practical example

"The title was rewritten by the editor" is flagged; "The editor rewrote the title" is not.

Understanding the results

Flagged sentences are candidates, not errors. Passive voice is correct when the actor is unknown or unimportant.

Limitations

This is a heuristic with false positives ("is closed" as a state) and misses. English only. Passive voice is not an SEO ranking issue.

Accuracy and report transparency

Results are computed in your browser from exactly what you enter. Deterministic steps (counting, parsing, encoding, validation) are verified by an automated test-suite with known answers. Where a method is a heuristic, the result panel says "estimated". No external data is used and nothing is invented.

Privacy

Your input never leaves your device for this tool. We count anonymous events (tool opened, run, copied) without storing what you typed. See the Privacy Policy.

Frequently asked questions

Should I remove all passive voice?

No. Rewrite only where an active sentence is clearer.

Is my data sent to your server?

No. This tool runs entirely in your browser, so the text or files you enter stay on your device. We do record anonymous counts of how often each tool is opened or run (no input data) to see which tools are useful.

How accurate are the results?

Counting, parsing, encoding and validation steps are deterministic and covered by automated tests with known answers. Anything based on a heuristic is labelled "estimated" in the result panel.

Is this tool really free?

Yes. There is no account, limit or paid plan. The site is supported by advertising, which is disclosed on our Advertising Disclosure page.
