PUCO vs Metis

Your AI knowledge, best prompts, and reusable workflows are always at your fingertips. PUCO is your personal AI launcher for iPhone and iPad: a searchable place to collect the prompts, instructions, frameworks, and repeatable workflows you rely on. Instead of rewriting the same request again and again, open a trusted template, fill in the details, preview the result, and copy a polished prompt in seconds. PUCO stands for Prompt, User, Constraints, Output: the four parts of an effective AI request. The app turns that structure into a simple workflow, so every prompt can carry the right task, your context, the rules to follow, and the format you want back. Use PUCO to: - Build a living library of your AI knowledge - Find the right instruction fast with search, favorites, recent prompts, and categories - Turn templates into guided fields instead of blank pages - Reuse proven workflows for writing, coding, research, images, marketing, study, support, planning, and more - Keep your best prompts close on iPhone and iPad - Create your own templates for work, clients, projects, and personal routines - Preview the final prompt before you paste it into your AI tool - Copy a finished prompt and optionally open your selected AI destination PUCO is for people who want better answers from AI without becoming full-time prompt engineers. It helps beginners discover what to ask, and gives power users a fast, organized system for the prompts they use every day. Stop hunting through notes, chats, screenshots, and old documents. Keep your AI knowledge organized, searchable, and ready whenever inspiration or work calls. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Metis is a native Markdown editor and local-first knowledge base. Your notes are just .md files in a folder you own - Metis is a fast, beautiful, native view over them. No lock-in, no proprietary format, no account required to write. WRITE IN LIVE PREVIEW A clean Obsidian-style editor styles your Markdown as you type - headings, bold, lists, quotes and code - while keeping the raw syntax one tap away. It feels like writing in a document, not in code. On iPad it's a full three-pane workspace with hardware-keyboard shortcuts. CONNECT YOUR IDEAS Link any two notes with [[wiki links]]. Backlinks appear automatically, so you always see what references the note you're reading. An interactive link graph shows your whole knowledge base at a glance - zoom, pan, and drag nodes to explore the connections. READ BEAUTIFULLY Reading mode renders the full document: headings, tables, task lists, images, syntax-highlighted code, Mermaid diagrams, and real math (LaTeX) rendered natively - no web view. ORGANIZE YOUR WAY Tag anything with #tags, group notes into folders, and see typed properties (status, owner, due...) that live as YAML front matter and are preserved as you edit. A fast switcher and full-text search get you anywhere instantly. ON-DEVICE AI (Apple Intelligence) Summarize a note, suggest tags or related links, and ask your whole vault a question - all running privately on your device. AI is optional; the app is fully functional without it. SYNC ACROSS YOUR DEVICES Keep your vault in iCloud and the same notes are on your Mac, iPad and iPhone - still as plain .md files you can open anywhere. Edits sync in the background, and Metis helps you resolve conflicts if two devices change the same note. LOCK WHAT MATTERS Any note can be locked with your notes password and opened with Face ID or Touch ID. Locked notes are encrypted on disk and stay encrypted in iCloud - and they're kept out of search and previews. PRIVATE AND YOURS Everything stays in plain files on your device. No tracking, no cloud lock-in. Open the same folder in any other Markdown editor whenever you like. Import an existing folder of notes (from Obsidian or anywhere) and Metis just works. ONE PURCHASE, ALL YOUR DEVICES A single one-time purchase unlocks Metis Pro on your Mac, iPad and iPhone - no subscription. Try everything free for 7 days. Metis is made by Empiric Apps.
