AI Essay Checker vs Writer's brew

AI Essay Checker (EssayCheck) is an online writing tool that scans essays for AI-generated text, grammar errors, and plagiarism in one editor. Paste or type your essay, then run AI detection, grammar checking, or plagiarism scanning separately or together. The AI detector estimates how much of your text may have been written by tools like ChatGPT, Gemini, Claude, or Copilot.

The grammar checker flags spelling mistakes and grammatical issues with real-time suggestions. The plagiarism scanner identifies duplicated or AI-copied content so you can edit before submitting. EssayCheck also includes an Essay Grader for automated scoring and feedback.

The platform supports English plus French, German, Spanish, Italian, Portuguese, Dutch, and Russian. Free accounts include monthly word limits on AI detection and plagiarism checks, with paid Basic and Pro plans for higher volumes.

Writer's brew is a macOS writing assistant that rewrites, summarizes, translates, and replies to text you highlight in any app. It runs from the menu bar, a Spotlight-style popup, or keyboard shortcuts, and includes snippets, 15+ text utilities, and OCR that pulls words from images before sending them to AI. You bring your own OpenAI API key, so usage costs go to OpenAI rather than a monthly SaaS bill.

Most writing assistants live inside one browser tab or web editor. Writer's brew works system-wide on macOS 15.0 or later, which suits people who jump between Notes, email, Slack, and docs all day. The trade-off is it is Mac-only, requires your own OpenAI key, and skips the managed cloud workflow that all-in-one web tools provide.

Product managers, founders, and students who draft in multiple native Mac apps are the core audience. Power users pair it with Raycast or PopClip extensions for one-click rewrites, while snippet forms with placeholders like {date} and {clipboard} handle repetitive replies.
