A QUICK WALKTHROUGH
How to use this tool
- Paste up to 50,000 characters of English text.
- Run the local pattern check.
- Review each hint in context; the tool does not rewrite or certify grammar.
Bounded English patterns
The browser checks a small maintained list of time cues: yesterday, last, ago, tomorrow, next, and now. It flags nearby common base, past, and -ing verb forms that conflict with those cues.
English-only heuristic and limits
This is an English spelling-pattern hint, not a grammar model. It does not parse clauses, infer meaning, recognize every verb or tense, or account for context, reported speech, irregular forms, or stylistic tense changes. Review every result manually.
Local processing
Text stays in this browser. The checker does not upload, rewrite, or save your input.
GOOD TO KNOW
Common questions
Does it check all English tenses?
No. It covers only the documented cue and verb-form patterns.
Can a result be wrong?
Yes. Context, irregular verbs, reported speech, and forms outside the small lists can change the correct tense.
Which languages are analyzed?
The interface has six locales, but the analysis is English-only.
