Stop losing what you copied. One Big Clipboard keeps a private, searchable history of everything that touches your clipboard — text, links, images, files, even colors — so the thing you copied an hour ago is one tap away. Most clipboard apps forget fast, or send your copied data to someone else's server. One Big Clipboard does neither. It remembers as much as you want, and it has no servers, no analytics, and no tracking at all. What you copy stays on your device and, if you choose, in your own private iCloud. EVERYTHING YOU COPY, KEPT - A searchable history of text, links, images, files, and colors - Copied hex and rgb() values are recognized and shown with a swatch - Fuzzy, relevance-ranked search finds the right clip fast - On-device OCR reads the text inside screenshots, so you can search images too - Code-aware: language detection and syntax highlighting for snippets of code SMART TOOLS, ON DEVICE - Tap any text clip to evaluate it as math, translate it, summarize it, or rewrite it more concisely - Multi-line clips can be reformatted as a checklist in one tap - Summarize and rewrite use Apple Intelligence on supported iPhones — never a cloud LLM ORGANIZE IT YOUR WAY - Snippets — hand-written reusable clips like signatures and boilerplate - Folders and tags to sort clips, plus pins for the ones you reuse constantly - Linked clips — relate clips captured at different times into one named set - Capture channels — pick an active folder and new clips file themselves into it - Smart Rules that auto-tag, file, or skip clips the moment they arrive - Color-coded filter chips — Text, Link, Email, Phone, Address, Code, Math each in their own color - Context notes — attach a free-text note to any clip so you remember why you kept it - Text transforms (change case, trim, pretty-print JSON, and more) with saved pipelines PASTE ANYWHERE, FAST - A keyboard extension to paste any clip straight into any app - A Share Extension to save into One Big Clipboard from anywhere - Home Screen and Lock Screen widgets for your most recent clips - Browse and filter clips by the app they came from PRIVATE BY DESIGN - Lock an individual clip with AES-256-GCM encryption behind Face ID or Touch ID - Encrypted clips store ciphertext only — only the device with the unlock key can decrypt them - Sensitive-looking clips are flagged and can be blurred - Lock the whole app behind Face ID or Touch ID - Erase everything — clips, folders, and iCloud copies — in one tap FREE, WITH AN OPTIONAL UPGRADE One Big Clipboard is free and fully usable on one device — every clip you save stays at hand for 30 days, and nothing is ever deleted while you decide. Premium unlocks your whole archive and adds private iCloud sync across iPhone, iPad, and the companion Mac app, so a clip copied on one device is on every other in seconds. A one-time purchase, no subscription. There is no account to create and nothing to sign up for. Install One Big Clipboard, copy something, and it is already working.
