You write the question. Wren's AI writes the answer back in neat handwriting, right on your page. It adds step-by-step math solves, function graphs, mind maps, tables, flowcharts and timelines in clean ink. On iPad, write a request with Apple Pencil, pause, and tap Keep. Or ask Study Buddy and tap Add to note. Most AI talks back in a chat window. Wren talks back in handwriting, on the same page you're taking notes on. Stuck at 11pm on a problem you can't crack? Write it on your board and ask. Wren writes the answer right next to your work, by hand: the graph, the steps, the mind map. No chat window. No copy and paste. Just your board, filling in. ONE ENDLESS WHITEBOARD Open a whiteboard note and you get one board with no pages and no edges. Work a problem in one corner. Sketch a cell in another. Zoom out and the whole topic sits on one screen. Want structure instead? Wren also has Notebooks with real pages and Documents for typed work. INK, NOT CARDS Wren's AI writes with real pen strokes, the same kind of ink you write with. It can put any of these on your board: • A few lines of text, like a definition or a short explanation • Graphs of the function you are working on • Diagrams and flowcharts • Mind maps that branch out from one idea • Timelines, from cell division to the Cold War • Checklists for what to do next • Formulas • Tables that line facts up side by side It all comes out in Wren's own neat hand, so it reads clearly next to your notes. THREE WAYS TO ASK Study Buddy. Open the chat, ask your question, and tap Add to note. The answer is written onto your page by hand. AI Tutor. Pin a Tutor answer you like, then add it to your page. It goes on as ink. Pen pause, on iPad. Write what you want with Apple Pencil, like "graph y = x^2 + 1" or "mind map the causes of World War I", then pause. A preview appears on your page. Keep it or discard it. YOU DECIDE WHAT STAYS On iPad, every pen pause starts as a preview. Tap Keep and it becomes ink on your board. Tap Discard and it is gone. Your board stays yours. ONE NIGHT AT THE BOARD 9pm, calculus. You write the function and ask for its graph. The curve shows up on the board next to your work. 10pm, biology. You ask Study Buddy for the stages of mitosis and tap Add to note. A timeline is written beside your sketch of the cell. 11pm, history. On iPad you write "mind map the causes of World War I" and pause your Apple Pencil. The preview shows the causes branching out. You keep it. Midnight, chemistry. You ask for a table comparing ionic and covalent bonds. It is written in neat rows, right on the board. Then you zoom out, and the whole night of studying is one board you can actually read. WRITE ON IPAD OR IPHONE On iPad, Wren works with Apple Pencil, with pressure and palm rejection, and pen pause is there whenever you stop to think. On iPhone, write with your finger and use Study Buddy's Add to note to bring answers onto your page. Your notes sync across your devices. WHY WE BUILT IT We're a brother and sister, both in college. We take notes every day, and we were tired of copying answers out of a chat window and into our notes. So we made the notes answer back. We are our own users, and Wren is the whiteboard we wanted. Wren is free to download. Some features are part of an optional subscription, billed to your Apple ID. It renews automatically unless you cancel at least 24 hours before the current period ends. You can manage or cancel it anytime in your App Store account settings. Terms of Use: https://www.getnotenest.com/terms Privacy Policy: https://www.getnotenest.com/privacy

Cribly is an agent, not another app full of forms. Every home inventory app hands you the same thing: empty fields, dropdowns, and a spreadsheet with better fonts. Nobody finishes them. Cribly starts from the opposite idea — you shouldn't be doing the data entry at all. You capture; your agent catalogs. NO FORMS. EVER. Snap a photo of anything — an appliance, a receipt, a manual, a paint can. Cribly's AI works out what it is, extracts the details, and files it in the right place. Model numbers, purchase dates, prices, warranty periods: read from the photo, not typed by you. A LIVING INVENTORY, BUILT FOR YOU Your home becomes an organized, searchable registry — rooms, appliances, systems, documents, and the receipts that prove it all. It stays current because adding to it costs you nothing more than pointing your camera. ASK YOUR HOME ANYTHING "When did we buy the dishwasher?" "Where's the manual for the furnace?" "What paint is in the bedroom?" Chat with Cribly by text or voice and get answers from your home's own records — because your agent has been keeping track all along. MAINTENANCE THAT MINDS ITSELF Cribly knows what's in your home, so it knows what needs care. Filter changes, servicing, seasonal upkeep — your agent suggests the tasks and reminds you at the right time. No recurring-reminder setup required. CAPTURE FROM ANYWHERE Forward a receipt by email. Send a photo over WhatsApp. Use the app or the web. However a document reaches you, it can reach your agent — and it gets filed the same way: automatically. FOR THE WHOLE HOUSEHOLD Invite family members to your home. Everyone can add with a snap, everyone can ask, and the answers come from one shared source of truth. WORKS WITH THE AI YOU ALREADY USE Cribly connects to assistants like Claude and ChatGPT, so you can ask about your home — or add to it — right from the AI tools you already talk to every day.
