高效工作 免费
Meet Claude, your AI problem solver and thinking partner. Claude works with you to write, research, code, and tackle hard problems. It works with your files, browser, and apps to get tasks done, so your chats can end in a finished report, spreadsheet, or presentation.
AI WRITING ASSISTANT
Turn rough ideas into polished work. Whether you're drafting social posts, professional emails, or long reports, Claude refines tone, structure, and clarity, iterating with you until your voice comes through. Get writing help that works with what you're trying to say, even while you're still figuring it out.
AI CODING AND PROGRAMMING HELP
Review code, debug complex issues, and explore new languages with an AI coding assistant that explains the "why" behind every fix. Work in Python, JavaScript, TypeScript, and dozens of other languages, from quick scripts to multi-step architecture. Claude Code is built into the app, so you can work on local projects, run sessions side by side, and review changes in one place.
GET THINGS DONE
Hand Claude a task and it works through each step with you. Turn a folder of receipts into an expense report, meeting notes into a project plan, or scattered research into a first draft. Claude reads, organizes, and creates files on your PC, with nothing to upload, and checks in when it needs a decision from you. Focus on something else, then come back to finished work. You choose which folders Claude can access.
CONNECT YOUR TOOLS
Connect Google Drive, Gmail, Calendar, and more of your everyday tools to bring your own context into the conversation. With Claude in Chrome, Claude can navigate sites, click, and fill in forms in your browser without switching windows. Desktop extensions connect Claude to local apps and data.
RESEARCH AND ANALYSIS
Go deeper on the questions that matter. Claude searches the web, compiles findings with citations, and pulls out what's useful. Whether you're running business analysis or exploring new ideas, work through the problem with Claude, from the first question to the one you didn't know to ask.
VISUAL ANALYSIS
Share a screenshot, PDF, or image, and Claude extracts text, interprets charts and graphs, reviews UI layouts and technical diagrams, and explains what it sees. Get feedback on app designs and data visualizations, or generate SVG code for graphics.
STAY IN YOUR FLOW
Open Claude from any app with a keyboard shortcut, or dictate when talking is faster than typing. Start a conversation on your PC and pick it up on the web or your phone.
EXPAND WHAT YOU CAN DO
Take on projects outside your usual expertise. Whether you're learning something new, navigating unfamiliar territory, or need a second opinion, Claude helps you take on the hard questions you otherwise don't have time for.
