How builders actually use AI.

Paste any function into Claude and describe the behavior you want to protect — not the implementation, the outcome users experience. Get a test file with happy path, realistic edge cases, and error states. Includes a note on which tests will break during refactoring so you only maintain the ones worth keeping. Stops the testing feels like overhead problem.

Copy the subject line and first 3 sentences of each email in your inbox. Paste into Claude with your role and one sentence about your current priorities. Get every email labeled — respond today, respond this week, FYI, or archive — with draft replies written for the urgent ones ready to review and send without rewording.

Run git log --oneline --since='24 hours ago', paste the output into Claude with your current blocker. Get a 3-paragraph async standup update — what shipped, what is in progress, what is blocked — written in natural language, not robot-speak. Takes 90 seconds instead of 10 minutes of blank staring at a cursor.

Small business owners receive the same customer questions dozens of times a day — pricing, hours, availability, how to order. This workflow shows you how to set up WhatsApp Business AI to handle those queries automatically, so you only see the messages that need a human. WhatsApp has over 2 billion active users globally and is the primary business communication channel across most of the world. Automate the repetitive 80% so you can focus on the conversations that actually close deals.

Run claude in your project root and prompt: audit this codebase for security vulnerabilities — focus on auth, input validation, SQL injection, exposed secrets, and dependency risks. Claude reads every relevant file autonomously, produces a prioritized vulnerability report with severity ratings, the exact file and line for each issue, and a fix for every critical finding. Replaces a $3,000 freelance audit.

Describe your mobile app in plain English — what problem it solves, what screens it needs, what happens when a user taps each button. Paste into Google Antigravity: build this as a Flutter app. Antigravity agents plan the architecture, generate all Dart files, set up navigation, wire up local state, and let you preview in a browser. Cross-platform mobile app — iOS and Android — from zero code. Free during preview.

Open the Codex app, queue 4-5 independent maintenance tasks across your codebase before you do anything else. Fix TypeScript errors, update webhook handlers, add error boundaries, migrate legacy middleware — each as a separate task running in parallel. By the time you have had coffee and checked Slack, 2-3 completed PRs are waiting for your review. This is the actual morning routine of developers using Codex in production at scale.
