Brrk is a reading companion for paper books and PDFs, built for people who read to learn, research, and write.

Turn paper-book bookmarks into usable text.

Snap a page you want to revisit and save the passage as text. Add notes while the context is still fresh. When you return later, you can review the passage without finding the sticky note and retyping every line.

Make difficult PDFs feel more like ebooks.

Instead of constantly zooming and panning around a fixed page, read extracted text in a flexible mobile layout. Adjust the text size, density, layout, and color theme to suit the way you read.

Look up words without leaving your reading flow.

Select an unfamiliar word, check its meaning, and save it with the sentence where you found it. Build an English and Japanese vocabulary list, search it later, and see how often you have encountered each word.

Before you begin

Your own Mistral API key is required for text extraction and vocabulary lookup. API usage is billed to your Mistral account.

Your key is stored in Android secure storage. Selected images or PDF content are sent directly to Mistral for processing and are not sent to the Brrk developer’s server.

Text recognition may contain errors. Always check the original page and page number before using a passage as a quotation.
