Active: “Developers are reviewing the code.”

About Passive Voice Checker

Detect passive voice constructions in your writing using pattern matching for forms of “to be” followed by past participles. Highlights passive constructions, shows the percentage of passive sentences, and suggests active rewrites. Aim for less than 10% passive voice for clear, direct writing.

How to Use Passive Voice Checker

1

Paste your text

Drop in whatever you're editing — an article, an email, a chapter, a memo. The checker handles any English prose, and there's no real upper limit on length beyond browser memory.

2

Run analysis

The tool scans for the be-verb plus past participle patterns that signal passive voice and highlights every match it finds. Some matches will be genuine passives, others will be false positives like 'I am pleased' that look similar but aren't actually passive.

3

Review each flag

Each highlight is a candidate, not a verdict. Read the sentence in context and decide whether the active version genuinely improves clarity. Plenty of passive constructions are perfectly fine when the actor is unknown or being deliberately downplayed.

Edit for clarity

For the flags worth changing, rewrite by promoting the actor to subject. 'The report was written by John' becomes 'John wrote the report' — shorter, more direct, and easier to read. The goal is fewer unnecessary passives, not zero.

When to Use Passive Voice Checker

Writing improvement

Passive constructions tend to make prose feel weak and indirect, and most writers slip into them without noticing. A checker that highlights every candidate gives you a chance to consider each one and decide whether the active version would land harder.

Business communications

Emails, proposals, and internal reports almost always read better in the active voice because the reader can tell at a glance who is doing what. The checker is particularly useful for executives and marketers who need to communicate decisively under time pressure.

Academic writing

Style guides vary across disciplines, but plenty of them (especially in journalism schools and the humanities) push hard toward active voice. Running a draft through a checker is a quick way to spot constructions that might draw a reviewer's eye.

Technical writing

Instructions become measurably clearer when phrased actively. 'Click the button' is shorter, less ambiguous, and easier to follow than 'The button should be clicked', and a checker that flags the latter helps documentation writers stay disciplined.

Passive Voice Checker Examples

Common passive

Input
The report was written by John.
Output
Flagged: passive voice. Active version: 'John wrote the report.'

This is the textbook shape — was plus past participle plus 'by' plus the agent. Inverting the order to subject-verb-object trims the word count and puts the doer up front, which usually reads better.

Hidden passive

Input
Mistakes were made.
Output
Flagged: passive voice. Hides who made mistakes. Active needs subject: 'I made mistakes' or 'The team made mistakes'.

This is the famous politicians' passive, used to dodge responsibility by omitting the agent entirely. The checker flags it because honest writing names the subject. Whether to rewrite is your call, but you should at least be making the choice consciously.

Acceptable passive

Input
The book was published in 1984.
Output
Passive flagged. But context: who published is unimportant. Active: 'Random House published the book in 1984.' If publisher unimportant, passive acceptable.

Not every flag is a problem. When the agent is unknown, irrelevant, or being deliberately de-emphasized, passive voice is the right call. The checker surfaces candidates and leaves the editorial judgment to you.

Tips & Best Practices for Passive Voice Checker

  • 1.Passive isn't inherently bad. It's the right tool when the actor is unknown ('the window was broken'), irrelevant, or deliberately being downplayed for emphasis. The checker flags candidates, not crimes.
  • 2.Active voice almost always reads more directly. Subject-verb-object is the most natural English pattern, and instruction-heavy writing in particular benefits from making the doer explicit.
  • 3.The 'by' phrase is the giveaway. Many passive constructions tack on 'by John' or 'by the system', which is exactly the agent that should usually be promoted to subject.
  • 4.The pattern the detector looks for is be-verb plus past participle. Things like 'was made', 'is being processed', and 'have been signed' all match, so be aware that complex tenses still get flagged.
  • 5.Aim for thoughtful editing rather than total elimination. Cutting every passive in a draft tends to produce stilted prose; cutting the unnecessary ones produces sharper writing.
  • 6.Instructions should always be active. 'Click the button' beats 'The button should be clicked' every single time, and the same applies to manuals, tutorials, and documentation generally.

Frequently Asked Questions

Passive voice is a sentence structure in which the subject receives the action rather than performs it. 'The ball was thrown by John' is passive; 'John threw the ball' is the active version. The grammatical signature is a be-verb (was, were, is, are, been, being) followed by a past participle.
