Companion Reader

Companion Reader helps you read deeply, keep highlights and notes together, and ask AI about selected passages in context.

Companion Reader is built for deep reading.

Import EPUB or Word books, read in a focused interface, and keep your thoughts connected to the source text. Highlights, underlines, quotes, notes, chapter summaries, and AI conversations stay organized around the book you are reading.

Key features:

• Import EPUB and Word documents
• Read with clean, adjustable typography
• Highlight, underline, and save important passages
• Write notes tied to the original text
• Ask AI about selected passages in context
• Generate book summaries and chapter insights
• Organize books by category
• Keep reading records, quotes, and notes together

Companion Reader does not replace reading. It helps you stay with the text, capture your own thinking, and turn reading into a reusable personal knowledge base.

AI features require your own supported API key. The first version is free to use with quota limits.
