Write by hand. Your other apps update themselves.

Write a task by hand and it shows up in Notion. Cross it off with your Pencil and it completes there too. Ask Claude to put something on tomorrow's page and it's waiting when you sit down.

How it works

One page. Every tool.

01

Write by hand

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.

02

It comes out structured

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.

03

Cross it off. It's done everywhere.

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

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

Agents read the page. And write back to it.

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.

GET /api/v1/pages/today
{
  "date": "2026-04-25",
  "paper": "lined",
  "tasks": [
    { "text": "Follow up on API spec", "age_days": 3 },
    { "text": "Team sync notes", "age_days": 0 }
  ],
  "events": [
    { "title": "Team sync", "time": "14:00" }
  ],
  "seeded_blocks": [
    { "origin": "claude", "content": "Briefing for today…" }
  ]
}
