What Penwell actually does with a document
What you can feed the app, what comes back, and which parts are worth using first. A plain tour, including the limits.
A forty-page PDF sits in one tab. The notebook you meant to fill is still empty.
Summarising the PDF is the easy part. The harder part is ending up with a page you can study from, or a post you can publish, without opening a design tool. That is what Penwell does: it takes a source and renders it as a notebook. The same source can come back as a social post pack instead.
What goes in
Text, a PDF, a URL, a YouTube video, an audio recording, or a Markdown file. The app is not fussy about the container.
The input changes what you get back. A lecture recording keeps the lecturer's examples and asides. A chapter PDF keeps the diagrams. A YouTube link gives you transcript quotes and timestamps in the reader, which is useful when you want to cite the exact minute. Pasting your own messy notes works too; sometimes that is the best source because you already did the filtering.
What comes out
A notebook is the study surface. Cornell pages, mind maps, sketchbook spreads, exam sheets, formula cards, vocab pages, ruled pages, and a few more styles. You can edit sections, highlight lines, add margin notes, sketch on the page, and choose a handwriting font.
A post pack is the same material laid out for a platform: an Instagram carousel, a Reddit card, a YouTube thumbnail, a thread. Each pack comes with a caption, hashtags, and alt text. You can switch themes after generation without spending another notebook.
The first three things to do
Ignore most of the toolbar for a week.
- Read the notebook and fix what the AI got wrong. Names, numbers, formulas, and diagrams are where it slips.
- Cover the Cornell cues and answer them out loud. That is the study loop, and it costs nothing.
- Export the cues as Anki CSV, or use the built-in flashcards, so the same questions come back tomorrow.
If you came for posting, generate one carousel from a source you know well. Read every slide. Then try a second theme. Restyling is free, and one theme switch plus one deleted sentence is usually the difference between a pack that looks like you and one that looks like a template.
What it will not do
It will not know what your exam covers. It will not replace checking the source, especially for anything with a number in it. And it will not make a thin source deep: if the PDF has three ideas, the notebook has three ideas.
The free plan is five notebooks a month, with a small watermark on social exports. Pro is $1.49 a month or $6.99 once, and it adds the AI study tools, clean social exports, and the brand kit. Neither plan is worth paying for before you have run your own material through the free one.
Tip
Start with the ugliest document you actually have to deal with. A clean example makes every tool look good.
One source in, a notebook or a post pack out. The rest is up to what you do with the page.
