Is this better than Grammarly?+

For grammar corrections, Grammarly has a large trained model that is excellent. Our checker uses a general LLM which is better at understanding context and nuance — it will catch issues Grammarly misses, especially in technical or creative writing. For basic spelling and grammar, both work well.

Does it work on long texts?+

Yes — paste essays, articles, reports or emails of any length. Very long texts (over 2000 words) may be split into sections for processing.

Will it change my meaning?+

The corrected version preserves your meaning — it only changes grammar, spelling and style, not the substance of what you wrote. Always review the output before using it.
