iPad · Apple Pencil · iPadOS 18+
Write your day by hand. Penlog reads your notation, so the task you write stays a task. It carries forward day to day until you cross it off, and everything on the page is searchable by what you wrote. And when you want it to, your Notion and your AI assistants can read the page and write back to it.
Free to write in. Made in Indianapolis.

How it works
Pick up your Apple Pencil. Your daily page is waiting — blank, dotted, grid, or lined. Every page is a day, so there's nothing to name and nothing to file.
Penlog reads your notation, not just your words. A bullet is a task, a circle is an event, an X is done. No tagging, no cleanup.
The task you wrote by hand becomes a real task in Notion. Cross it off with the Pencil and it completes there too. It works in reverse as well: ask Claude to put something on tomorrow's page, and your calendar arrives the same way, as the day's events already on the page.
Integrations
Penlog doesn't replace your planning stack. It gives everything in it a window into your handwritten day.
Official Notion Marketplace connectionAPI & MCP
Every journal page is a REST resource, and it arrives already sorted into tasks, events, and notes rather than as a wall of transcribed text. Any MCP-compatible agent can read it and add typed text alongside your ink.
