The AI-powered online service automatically checks punctuation in Russian and English texts: finds missing and extra commas, colons, dashes, quotes, hyphens, semicolons; suggests fixes with rule explanations and highlights of edge cases. Paste the text — get a neat, readable version in seconds.
How it works
- Text input — paste a paragraph or an article.
- AI analysis — the model performs a syntactic-punctuation parse: finds boundaries of constructs (homogeneous members, parenthetical words, phrases, complex sentences), checks direct speech, lists, quotes.
- Edit suggestions with explanations (optional)
- We show where a comma is/isn't needed and why (a brief rule reference).
- Separately flag dashes/colons, quotes, hyphens/dashes, semicolons.
- Style settings (optional). Modes: educational (more explanations), editorial (minimum extra), strict (GOST), media style.
- Export and integration — copy, export edits to TXT.
