Description

Penlog turns your handwritten Apple Pencil journal into structured data you can work with in ChatGPT. Ask what you wrote on a given day, search your pages by topic, and pull up your open tasks with their current status. You can also add a task or mark one done, and it appears on your handwritten page and syncs through to Notion. Write by hand, then work with everything you wrote.

How do I improve a ChatGPT Plugin's discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
