Read It Here, Remember It Later

Most of what you read is gone in a week. Interact gives a book chapter or a web article a clean page to read on, keeps your place, and turns the parts worth keeping into practice you'll see again.

A chapter of The Elements of Style open as a Document, set like a book page with a reading progress bar — A chapter of a PDF, open as a Document.

A page made for reading

Set like a book

One centered column in a serif face, with the headings, quotes, tables, math, and code the source had. The line above the title says which book or Collection the Document belongs to and how many minutes it takes to read.

A progress bar

A thin bar across the top fills as you move down the page, so you know how much is left without scrolling to check.

Focus mode

Press F and the tools beside the page go away, leaving the text by itself. Press F again to bring them back.

Pick up where you stopped

Click the paragraph you stopped on and choose Save my spot. A bookmark marks the line, and a Continue button on the Documents and Uploads pages takes you straight back to it.

A PDF keeps one spot across all of its chapters, the way a book has one bookmark. Your spot is saved to your account, so the iPhone and iPad apps open to the same place.

Keep a book together

The chapters of a PDF stay grouped under its cover, in page order, each one a Document of its own. For everything else there are Collections. Gather web pages, or Documents you wrote, under one name and put them in the order you want to read them.

Drag one Document onto another to start a Collection, or choose one when you bring in a new page. When you reach the end of a Document, the next chapter or the next Document in the Collection is one click away.

The Documents list with a PDF's chapters grouped under its cover and a Collection of web pages below it — A PDF's chapters stay together, and Collections group everything else.

The end of a chapter in a Document, with a card offering the next chapter of the book — Finish a chapter and the next one is waiting.

Turn what you read into practice

From one passage

Click a paragraph or a list item to select it, or a heading to select its whole section, then choose Generate. Interact makes interactives from that part and nothing else.

From the whole Document

Open Generate interactives and work through the Document in batches. Each batch reads the next stretch of text, and a progress bar shows how much you've covered. Turn on Keep going to run batch after batch until the end.

Edit as you go

The same toolbar edits or deletes a selection, with undo. Cut the acknowledgments, fix a typo, or trim a chapter down to the part you need.

Where Documents come from

A PDF

Upload a textbook and read it a chapter at a time. The PDF Study Tools page covers how a PDF becomes Documents.

A web page

Paste a link on the Create page and the page is kept as a Document. A short page becomes interactives right away. A long one is saved for you to read and work through a section at a time. More on the Website to Flashcards page.

Your own writing

Start a new Document and write or paste in Markdown.

Common questions

What can I read?

PDFs up to 10 MB, public web pages, and anything you write or paste in Markdown. There is no EPUB or Kindle import.

Can I highlight and take notes?

Not yet. You can select a passage to generate from it, save your spot on it, or edit it, but there are no saved highlights or margin notes.

Does it work on my phone?

Yes. The iPhone and iPad apps have Documents and Uploads under the More tab, with the same saved spot and the same Collections.

Is it free?

Reading, saving your spot, and Collections are free on every plan. Bringing in a PDF or a web page and generating interactives count toward the free plan's 10 AI generations a month.
