About

grep

Features
Read full description

grep is your personal assistant. It knows everything you've saved, it knows you, and it gets things done. Save a page, a video, a place, a book or a note in one tap. Later, just ask: "What was that pasta place Sam sent me?" "What have I saved about heat pumps?" grep answers from your own things, by text or by voice. SAVE ANYTHING • Share to grep from any app, or save straight from Safari • Web pages, videos, places, books, photos, notes and voice memos • Point the camera at a place, a book or a film poster and add it PLAN YOUR DAY • Calendar, tasks, habits and reminders live next to what you saved • Collections for the things you want to share • Projects for the things you're going to do, with their files and checklists EVERYWHERE ON YOUR DEVICES • Widgets for your Home Screen and Lock Screen, and buttons in Control Center • Add a note or a to-do from Siri and Shortcuts • iPhone, iPad and Mac, with the same library on each A HOME THAT IS YOURS • Everything is kept as ordinary files that belong to you • Works offline • No ads. No account needed to start saving WITH YOUR GREP NODE The app saves and organises on its own. Add a grep node, which is a Mac or Linux computer of your own that stays on, or one we run just for you, and grep becomes your assistant: • Ask in plain words and get an answer, with the things you saved behind it • Talk instead of typing on iPhone and Mac • It works out what each thing you save is, and files it for you • Ask about the wider world too: it searches the web and finds real places, with opening hours • It gets things done: "Put dinner with Sam on Friday at 7." "Remind me to renew my passport." • Give it a bigger job and it works in the background, then comes back with the result • Routines on your schedule, and follow-ups when there is news • It remembers what you tell it about yourself, and you can read, correct or erase that memory • It asks before it changes, sends or deletes anything. One button stops everything it is doing • Your devices stay in sync Set one up at grepit.app. grep is the same on every device, and it grows with you. More is on the way.

Read full description

A drop zone for the markdown documents your AI assistant writes. MD Inbox watches a folder in iCloud Drive on your Mac. When Claude, ChatGPT, Cursor, or any other AI tool saves a markdown file there — a plan, spec, code review, design doc, meeting notes — it appears on your iPhone within seconds. Read it on the go, pin the ones that matter, delete the rest. HOW IT WORKS 1. Pick any folder in iCloud Drive as your inbox. 2. Copy a short prompt into your AI agent's system prompt. 3. From now on, finished documents your agent produces show up here. FEATURES • Live iCloud sync — files appear seconds after your agent saves them • Date-grouped sidebar: Pinned, Today, Yesterday, This Week, This Month, Older • Swipe to delete, tap to pin, multi-select for batch cleanup • Auto-delete after a configurable threshold to keep the inbox tidy • Pinned and read state sync between devices via iCloud • Native markdown rendering with code blocks, tables, and images • Share extension — send markdown from any app THREE BUILT-IN AGENT PRESETS • Plans & Specs — agent auto-saves substantial deliverables • On-Demand — agent saves only when you ask • Quick Captures — short, timestamped notes No account, no server — your files live in your own iCloud Drive.
