Claude packs far more features than most users realize. Its Projects feature lets you save chat contexts—documents, instructions, preferences—so Claude picks up where you left off instead of starting fresh each time. Artifacts bring real tools into chats: calculators, habit trackers, interactive charts and even games live inside the sidebar without copying code out. Flip on Adaptive Thinking (formerly Extended Thinking) to watch Claude break down complex problems step by step. And enable Memory so it learns your background, work style and ongoing projects across sessions. You can also reshape Claude’s role with targeted prompts. A “Personal Psychologist” prompt turns it into a CBT-style coach that asks probing questions. The “Hard Mentor” mode tears into your assumptions instead of praising your ideas. Custom prompts make it a personal trainer, a conversation practice partner or a devil’s advocate that drills holes in your plan before you commit. Each role lives in a new chat—just paste the prompt and Claude shifts gears instantly. Beyond the web app, Claude offers tools that blur the line between AI and your workflows. The Chrome extension reads pages, fills forms and navigates for you. Cowork, the desktop app, hooks into your file system so Claude edits files, organizes folders and builds documents without manual copy-paste. Scheduled Tasks run prompts automatically on your schedule—daily reports, reminders, data pulls—with results saved to a chosen folder. Finally, Cowork supports Skills (think apps) and CLAUDE.md files for project rules. Install prebuilt Skills to handle PDFs, PowerPoints or custom workflows. Drop a CLAUDE.md in your project folder and Claude loads your coding conventions, brand voice and terminology every session. And for developers, Claude Code lives in your terminal. Describe features in plain English and it writes, tests and fixes production-level code inside your environment. Each of these takes minutes to set up and transforms Claude from a simple chatbot into a powerful, integrated assistant.
