Al Butler puts an AI-powered personal assistant in your pocket. Manage your money, diagnose your car, capture ideas, and stay on top of your tasks — without switching between a dozen apps. Smart Budgeting: - Add your bank accounts, spending accounts, and credit cards in one place. Set monthly and daily budgets, then track every transaction manually or by parsing your bank SMS messages with on-device AI. Al Butler breaks down your spending by category so you always know where your money goes. It even fetches your credit card fees automatically. Car Diagnostics: - Pair a Bluetooth OBD-II adapter and let AI read your car's sensors, pull trouble codes, and explain what's actually going on — in plain language. Describe a symptom, and Al Butler picks the right data points, collects live readings, and delivers a clear diagnosis. Works with most cars from 1996 onward. Ideas That Grow: - Save a half-formed thought and come back to it later — or let AI expand it into a full implementation plan, business model, or SWOT analysis. Tag, categorize, and search your ideas whenever inspiration strikes. Todos That Stay Simple: - Create tasks with priorities and due dates. Filter by status, track your completion rate, and get a quick glance at what's overdue from the home dashboard. Loans at a Glance: - Keep track of money you've lent and money you owe. Log partial payments and watch the balance go down. Your AI, Your Choice: - Use on-device AI for complete privacy, or connect your own API key for Google Gemini, OpenAI, or Anthropic. Pick the exact model you want — from fast and lightweight to deep reasoning.
