A handwritten iPad journal that puts today's tasks and events on your page before you open it — and makes your writing readable by the software you already use. A handwritten journal for people who use software. Penlog is a daily journal for iPad and Apple Pencil. Every day gets its own page. You write with your Pencil, and the page stays yours — searchable by what you wrote, kept across your devices the way iCloud keeps things. Two things make it different: your page comes prepared, and your handwriting doesn't stay trapped on the glass. YOUR PLANS, ALREADY ON THE PAGE Connect Notion, your calendar, ChatGPT, Claude — whatever you already use. Penlog seeds today's events and open tasks onto your page before you open it, then keeps them in sync as you write. Nothing to retype. Mornings are for sorting, not setup. YOUR WRITING, READABLE BY THE TOOLS YOU USE Every page is available through a simple API. Your handwritten thinking becomes context the agents you work with every day can read — the same way they read your email or your calendar, now also reading what you wrote by hand. BUILT FOR WRITING, NOT FOR MEETINGS Penlog isn't a productivity suite. It's a daily notebook that knows about your obligations without shouting about them. You decide what to keep and what to cross out. ALREADY USING SOMETHING ELSE? Day One for the writing. Notion for the planning. GoodNotes for the Pencil. Penlog for when you want them all on the same page. Made in Indianapolis. Built for iPad and Apple Pencil. Works with Notion, Apple Calendar, ChatGPT, Claude, and the agents you're already running. Because the writing is the thinking. — — — PENLOG PRO Penlog is free to write in. Penlog Pro unlocks two-way sync with Notion and your calendar, cloud backup of every page, and the API that makes your handwriting readable by your tools and agents.
