How this service works
Deterministic, rule-based proofreading flags — passive voice, adverbs, wordiness, filler, repeated words, whitespace, a/an, punctuation, sentence length, capitalization. Each flag carries an offset + suggestion. For long text use POST.
Output
A list of flagged issues in the text, each with the issue type (e.g. passive voice, adverb, wordiness), character offset, the problematic text, and a suggested fix, plus a summary object and total issue count.
Example use cases
Example prompt
“Can you proofread this paragraph for me and flag any passive voice, adverbs, filler words, or other style issues: "The report was written by the team very quickly, and it was basically submitted without any really careful review."”
Technical details
Endpoint
GEThttps://touchstone.locomot.io/proofreadWhen to prefer
Use this endpoint when you need deterministic, rule-based proofreading without AI generation — it gives consistent, reproducible flags with exact character offsets and is ideal for programmatic style checking, linting pipelines, or when you want transparent, auditable rule application rather than probabilistic AI suggestions.
Side effects
- Missing 'text' query parameter returns an error
- Text too long for GET request (URL length limits) — use POST instead
- Empty string input returns zero issues with no flags
- Non-English text may produce false positives or miss issues since rules are English-centric
