Writing in the active voice generally produces clearer, more direct, and more engaging sentences. While passive voice has legitimate uses in technical reporting and objective scientific documentation, unintentional over-reliance on passive constructions can obscure the actor and dilute prose clarity.
This passive voice checker uses deterministic grammatical heuristics to identify sentences containing auxiliary forms of 'to be' paired with regular (-ed) and irregular past participles, as well as agent 'by' prepositional phrases. It provides explainable candidate diagnostics with confidence ratings, operating entirely in your browser without opaque cloud AI models.
Core Tool Capabilities
- Deterministic Heuristic Detection: Detects forms of 'to be' (is, are, was, were, been, being) paired with regular and irregular participles.
- Confidence Scoring & Filters: Categorizes findings into Strong and Possible candidates with instant toggle filters.
- Agent Phrase Recognition: Identifies explicit 'by [agent]' prepositional phrases to pinpoint who or what performs the action.
- Diagnostic Findings Report: Generates structured copyable reports listing sentence index, matched construction, and grammar heuristics.

Editorial Proofreading
Quickly identify sentences that omit the actor or bury key actions under complex verb phrases.
Frequently Asked Questions
- Does this tool catch all passive voice sentences?
- No automated tool can achieve 100% grammatical certainty because English syntax is rich in context-dependent ambiguities. The tool uses deterministic grammatical heuristics to highlight likely and possible passive constructions for human review.
- Is passive voice always incorrect?
- No. Passive voice is completely legitimate when the actor is unknown, unimportant, or when the focus should remain on the recipient of the action (e.g., 'The experiment was conducted under vacuum'). The goal is intentional usage rather than accidental overuse.
- How does it detect irregular verbs?
- The engine contains an extensive dictionary of English irregular past participles (e.g., written, seen, made, given, taken, built) and checks for intervening adverbs (e.g., 'was quickly deployed').
- Are my manuscripts transmitted or saved on a server?
- No. All tokenization and grammar checking run purely in your browser's local memory.
