Tips for Best Proofreading Results
- •Complete Confidentiality: Unlike commercial proofreaders that store your documents on remote clouds, ECSOT processes every character in memory.
- •Context-Aware Grammar: On-device models recognize homophones (e.g. 'their' vs 'they're', 'its' vs 'it's') by analyzing surrounding context.
- •Double Check Output: While on-device models are remarkably capable, always verify technical terminology and specific proper names.
- •Combine with Rewriter: Use the AI Text Rewriter tool afterwards if you want to shift tone to formal or casual styles.
