PouchBrain — Thoughts, sorted. Your brain is for processing, not storage. PouchBrain is a beautifully simple, AI-powered second brain that lets you offload every thought, task, and idea, clearing up your mental space for the thinking, not the filing. Open, say or type what’s on your mind, add a photo or screenshot if you like, hit Pouch, and close. PouchBrain understands natural language (“get milk, bread, eggs”, “call the bank tomorrow 9am”, “season three game of thrones”), then files it exactly where it belongs. No forms, folders, or friction. Capture your thoughts three ways Type into the Pouch modal anywhere in the app (and on desktop). Talk with Voice Note Pouching; record up to 30s; we transcribe and sort it. Snap with Image Pouching; upload a product photo/screenshot; we parse and add it. Organize without effort Smart AI Sorting routes items to To-Do, Shopping, or Buckets, cleans titles, and applies helpful defaults. Edit anytime with one tap. Personal / Work filter is built-in to To-Do for quick context switching. Project Tags add colour-coded pills to tasks so related work stands out instantly. To-Do that respects your time Low-pressure urgencies keep focus on what matters now, soon, and later. Priority Mode → tap Prioritise, drag to reorder, then Save. Prefer lists? Turn it off for A→Z sorting. Scheduling & Recurring with a clear recurring icon. Mention a date/time and we’ll schedule it automatically. Reliable reminders via Push Notifications. Notes for details, multi-select complete, and a tidy confirmation tick after swiping done. One-way Calendar Sync mirrors scheduled items to your native calendar. The shopping list you actually use Needs vs Wants filter for better budgeting. Quantities on every item (quick-adjust). Colour-coded categories at a glance. Add by voice or image—we’ll parse item details automatically. Buckets for everything else Seven buckets (Taste, Watch, Listen, Read, Play, Location, Idea) to park recommendations and inspiration. Smarter Buckets auto-add a helpful link plus three key details based on the bucket type (e.g., cuisine/price/suburb for restaurants). LifeLists templates Seven fully-editable master lists: Cleaning, Inventories, Groceries, Personal Care, Daily Routines, Home Upgrades, Weekly Planner. Export to Shopping sends ticked items as Needs + Now under Supermarket by default. Share & collaborate via contacts to stay in sync with family or housemates. Works everywhere Desktop support at pouchbrain.app with a keyboard-friendly layout. Light & Dark done properly (custom icons in both). iOS niceties: Lock Screen widget for one-tap pouching, and Siri for hands-free capture. Honest pricing All features. One price. No “pro” tiers or hidden upsells—$2.99/month to keep your brain decluttered and your life on track. No ads. We don’t sell your data. PouchBrain. Thoughts, sorted.
