WriteSmith AI 是什么
AI writing tools that work where you write. Humanise, grammar check, paraphrase — right on LinkedIn, Gmail, Docs & job boards. WriteSmith AI is a free browser extension that brings context-aware writing tools to every page you visit.
HOW IT WORKS
When you select text on any webpage, WriteSmith detects where you are and shows the most relevant tools. Writing an email? You'll see tools for professional communication and tone adjustment. Browsing a job listing? You'll see tools to build a tailored application pack. Working on a document? You'll see grammar checking, paraphrasing, and humanisation tools. The extension adapts automatically so you always see what's useful for the page you're on.
Select text, click the small floating button that appears, and pick a tool. The result appears in a slide-in overlay where you can replace your original text in-place, copy the result to your clipboard, or open it on writesmith.ai for further editing. In-place replacement works inside email composers, post editors, comment boxes, and any standard text input across the web.
WHAT YOU CAN DO
Humanise AI-drafted text so it reads naturally and sounds like you wrote it. The humaniser uses persona-based rewriting rather than mechanical word swapping, matching your text to a specific writing voice based on your chosen readability level, tone, and creativity settings.
展开其余商店介绍▾
Check grammar and get two suggestions for every error: the minimum fix and a "better version" showing how a confident writer would rephrase the entire sentence. This means you learn to write better, not just fix mistakes.
Paraphrase text in five distinct modes depending on what you need: standard for general rewriting, fluent for natural flow, academic for formal writing, concise for cutting words, or creative for fresh phrasing.
Adjust the tone of any text between formal, casual, academic, and professional registers without changing the meaning.
Build a complete job application pack from a single job listing. When you're viewing a job posting, one click captures the full description and generates a tailored CV, personalised cover letter, interview preparation with STAR method answers, smart questions to ask the interviewer, a company brief, and suggested profile tweaks. The extension also detects applicant tracking system pages and company career sites using intelligent page analysis.
Check your CV against applicant tracking systems to catch keyword mismatches that cause automated rejections before you submit your application.
Access 42 writing tools covering essays, professional emails, career documents, content creation, academic work, and business writing. Every tool is available from the extension menu or directly at writesmith.ai.
THREE WAYS TO LAUNCH A TOOL
Floating action button: a small blue button appears below any text selection of ten or more characters. Click it to open the context-aware tool menu.
Right-click menu: select text, right-click, and choose a tool from the WriteSmith AI submenu. The menu adapts to show the most relevant tools for the site you're on.
Keyboard shortcuts: press Cmd+Shift+E on Mac or Ctrl+Shift+E on Windows to open the tool menu. Press Cmd+Shift+U or Ctrl+Shift+U to humanise selected text instantly without opening the menu.
FREE TO USE
Every tool is free with daily usage limits. No credit card required. No signup needed to start. Try the extension with five free uses of any in-place tool before creating an account. Tools that open on writesmith.ai always work without signing in. Premium plans are available for users who need higher volume or advanced features.
LIGHT AND DARK MODE
The tool menu, result overlay, and settings page follow your system theme automatically. You can also lock the theme to light or dark in the extension settings.
PRIVACY
