Why the rewrite is better: The corrected line matches the singular subject “neither” with “seems” and removes the extra object pronoun that made the relative clause ungrammatical.

Application statement

Before

After reviewing the role, the chance to lead cross-functional projects are what excites me most.

After

After reviewing the role, I am most excited by the chance to lead cross-functional projects.

Why the rewrite is better: The rewrite supplies a logical subject for the opening phrase and removes the disagreement between the singular “chance” and plural “are.”

A sentence can contain correctly spelled words and still feel wrong because its agreement, tense, modifier, or clause structure is off. This checker resolves those connections as a complete unit instead of treating each word separately. It is useful for a line you have reread too many times, especially in an application, report, or important message. The embedded checker offers a limited set of no-account runs; PromptDC’s desktop and Chrome experiences handle selected sentences directly inside your usual writing surface.
