Correctarium

Correctarium is described in independent listicle coverage as an application for eliminating errors in grammar, spelling and punctuation, launched with the /proof command - a specific, memorable workflow rather than a vague general chatbot interaction. That command-based structure signals a bot built for a repeatable, predictable task rather than an open-ended conversation. As a dedicated proofreading tool, it sits between a spell-checker like ViSpelling, which only flags errors, and a full rewriting bot like FixMeBot, which changes tone and structure. Correctarium's job is narrower and more conservative: fix what's objectively wrong (grammar, spelling, punctuation) without necessarily rephrasing your voice or style. For anyone who wants their own writing style left intact but the technical mistakes cleaned up - a common need for non-native speakers, students or anyone proofreading before sending something important - that conservative, correction-only approach can be exactly right, whereas a bot that rewrites everything might strip out your original voice.
