Which are the primary technologies used for building your product?

WProofreader's answer

We developed RedPenNet, our in-house AI architecture, which uses pre-trained models to detect errors and suggest corrections. Post-processing then classifies each suggestion to make it accurate and context-aware.

Key advantages of RedPenNet:

Context analysis—checks text at the sentence level, considering word usage and meaning. Interconnected error detection—identifies related mistakes using an autoregressive method for more comprehensive corrections. Predictable corrections—anticipates how changes affect sentence meaning, reducing new errors. Custom approach—combines AI and rules-based validation for more accurate and reliable results. Advanced error correction—more precise and context-aware than traditional rules-based engines.
