Proofread

For readers and authors

Make more of what you read.

Read books, articles, and documents with an AI companion that answers from the text. Every published text gets a Bitcoin timestamp, so you can check that it hasn't changed.

You don't need an account to read.

How it works

Here is a short sample page. The notes show what you can do with any text you open.

On paying attention

We read to meet ideas we would not have had on our own, and now and then a question we did not know to ask. One page can take you a long way from where you started.

Understanding usually starts when we slow down. We stop at a word, notice how two ideas connect, or go back to a sentence that changes how the rest of the page reads.

A good reading tool leaves room for questions and keeps a way back to the words that raised them.

Read

Read at your own pace.

Open a text, pick a section, and read. Your place is saved on this device, and the language menu lists any translations.

Ask

Ask about what you read.

The companion can explain a passage, talk it through with you, or quiz you on it. Follow its citations to check an answer against the text.

What does the writer mean by attention?

Illustrative answer · not a live AI response

Slowing down: stopping at a word, noticing how two ideas connect, going back to a sentence. The writer says that is where understanding starts.

Verify

Check that the text hasn't changed.

When a text is published, its fingerprint is recorded with a Bitcoin timestamp. If the text still gives the same fingerprint, it hasn't changed since. A match tells you nothing about whether what it says is true.
