How it works
One page. Every tool.
Write by hand
Pick up your Apple Pencil. Your daily page is waiting — blank, dotted, grid, or lined. Ink stays on device.
Penlog reads it
As you write, Penlog picks out your tasks and notes. No tagging, no cleanup.
Your tools loop in
Notion, Claude, and ChatGPT read your page and write back as typed blocks beside your ink. Your calendar flows in too — the day's events, right on the page.
Integrations
And also, not instead of.
Penlog doesn't replace your planning stack. It gives everything in it a window into your handwritten day.
API & MCP
Your handwriting, addressable.
Every journal page is a REST resource. Any MCP-compatible agent can read your OCR'd text and write typed blocks alongside your ink.
