Which passives can be converted automatically?

Those that name their actor in a by-phrase and use a covered tense: was or were with a participle, or has been, have been and had been. Irregular participles come from a published table, and regular participles are already their own past tense.

Why was my sentence left unchanged?

Each finding carries the reason. Usually the clause has no named actor, the tense is not covered (present-tense passives are left alone), or the participle is adjectival — was tired describes a state rather than an action.

Is the passive voice wrong?

No. It is a tool with real uses: when the actor is unknown, when the object is the point of the sentence, or when naming the actor would be unfair. The converter makes the choice visible rather than abolishing it.

What about a by-phrase like by Friday?

It is not an actor. Times, dates, weekdays, months and idioms such as by hand, by default and by mistake are recognised and treated as no agent, so the clause is reported rather than rewritten.

Does the text leave my browser?

No. The detection and the rewrite are local rules over the pasted text, which stays in the tab.

Scope and limits

A clause is only rewritten when it names its actor in a by-phrase and uses a tense the published participle table covers: was/were and has/have/had been. Everything else is left exactly as written.

The passive is not an error. Scientists and reporters use it deliberately when the actor is unknown, or when the object of the sentence is the point. Convert only where an actor exists and matters.

The active voice converter finds passive clauses, recasts the ones that name their actor and use a covered tense, and reports the rest with the reason they were left exactly as written.

What is Active Voice Converter?

The active voice converter starts from the definition. A passive clause is a form of be plus a past participle, and it only becomes an active clause when the actor is named in a by-phrase — otherwise there is nothing to put in the subject position. So the engine finds every be-plus-participle construction, takes the actor from a following by-phrase, and rebuilds only what it can rebuild correctly.

The verb table decides the rest. Was and were plus a participle become simple past, using a published list of irregular participles: written becomes wrote, taken becomes took, made becomes made, and a regular participle such as delivered is already its own past. Has been, have been and had been become the perfect active, so the report has approved the budget reads naturally from the budget has been approved by the board.

Everything outside those rules is reported rather than forced. An agentless passive — the decision was made — is left alone with the note that a named actor is missing and that the passive may be the right choice if the actor is unknown or unimportant. A present-tense passive such as the plan is reviewed by the committee is left alone with the tense named, because the tool does not guess at third-person forms. Adjectival participles are excluded outright: she was tired by noon is a state, not an action, and recasting it would produce nonsense.

The exclusions matter as much as the conversions. A by-phrase that is really a time or an idiom — by Friday, by hand, by default, by mistake, by all means — is not an actor, and treating it as one is the classic failure of a naive converter. Names that merely start like a month are protected too, so Maya is never mistaken for May.

The page is explicit that the passive is not an error. Scientific writing, incident reports and news copy use it deliberately when the object of the sentence is the point or the actor is genuinely unknown. The tool converts the clear cases, lists the others with reasons, and leaves the judgement where it belongs. The counts on the page — converted, no named actor, left as written — tell you at a glance how much of the paragraph the rules actually reached.

The move from passive to active is a choice about emphasis rather than a rule of grammar, and sentence clarity is usually the reason to make it: a reader who knows who acted can follow the consequence without guessing.

Practically, a pass takes a minute: paste a paragraph, read the converted version, scan the amber findings for the clauses that need a human, and copy the result. Every original clause is shown beside its rewrite, so nothing is lost if a recast reads worse in context. Nothing is uploaded, and the whole conversion happens in the tab.

When a paragraph is flat for other reasons, the {{sentence-rewriter|Sentence Rewriter}} changes sentence shape and the {{simplify-text-tool|Simplify Text Tool}} trims the weight from long sentences.

One caution worth repeating: the passive voice is not a fault. Convert a passive only when naming the actor adds information; if it adds an accusation or a guess, the passive was doing honest work.

How to use Active Voice Converter

Paste a paragraph containing passive clauses.
Read the active version and the converted-clause count.
Scan the clause list for the amber findings, which carry a reason.
Add a named actor where one exists, then convert that clause by hand or with the tool.
Copy the result and check each recast clause in the context of the paragraph.

When to use Active Voice Converter vs related tools

Use the active voice converter on reports, procedures and briefings where too many clauses have lost their subject and the prose has gone grey. It recasts the clauses that name their actor and can be rebuilt safely, and it reports the ones that cannot.

If the paragraphs are still long and padded after conversion, the Simplify Text Tool replaces wordy phrases and splits sentences, while the Sentence Rewriter handles prose whose problem is shape rather than voice.
