By Sophia ReedDigital reading software maker Readwise has launched the Readwise Books app, an all-in-one ebook storefront and granular habit tracker built to compete with Amazon Kindle and Goodreads. Combining millions of licensed titles with fitness-style reading analytics and native artificial intelligence agent integration, the platform targets dedicated readers seeking an open ecosystem.
Currently available in invite-only beta in the United States as a free mobile and desktop application, the Readwise Books app offers a licensed catalog of millions of ebooks spanning all Big Five publishing houses alongside independent presses. In addition to digital downloads and select audiobooks, users can order physical print editions fulfilled through Bookshop.org’s distribution network, supporting local independent bookstores in the process. The launch directly confronts a highly concentrated digital publishing market where Amazon’s Kindle ecosystem—including its Kindle+ subscription service—commands an estimated 83 percent share of ebook sales.
In the consumer Technology space, software developers have rarely challenged dominant ebook marketplaces because licensing major publisher catalogs and digital rights management systems requires complex, multi-year negotiations. Readwise, already widely known among academic researchers and avid readers for its highlight-syncing tools and Readwise Reader application, spent months securing direct publisher agreements so users can purchase, read, annotate, and track books within a single unified workflow.
Fitness-Style Reading Analytics and Interoperable Formats
Rather than offering only basic page counts or annual book tallies like Goodreads, the Readwise Books app introduces detailed session telemetry that the company compares to Strava for reading. As users progress through a chapter, the application calculates real-time metrics including total words read, reading pace, session depth, immersion scores, and daily consistency streaks. Readers can visualize when they focus best during the day, compare reading velocity across literary genres, and export annotated highlights directly into their personal knowledge management systems.
To address long-standing consumer frustrations over digital ecosystem lock-in, Readwise supports DRM-free EPUB file uploads alongside Readium Licensed Content Protection downloads for publisher-protected titles. The application also includes built-in text-to-speech narration so readers can switch seamlessly between reading on screen and listening while commuting or exercising. By supporting open industry standards and portable annotations, the platform ensures customers are not trapped inside a single hardware vendor’s proprietary file format when upgrading their devices.
Connecting Reading Libraries to AI Agents via MCP
Beyond consumer reading features, Readwise equipped the new platform with a public application programming interface and a dedicated Model Context Protocol server featuring 13 specialized tools for artificial intelligence agents. Through the MCP server, users can grant their preferred AI assistants permission to search their personal reading history, retrieve book metadata, analyze reading pace trends, or surface relevant book passages during writing, study, and research sessions.
Carving out meaningful market share against an incumbent holding 83 percent of the digital book sector remains a formidable challenge, especially given consumer reliance on dedicated e-ink hardware devices. Nevertheless, by blending a licensed commercial bookstore, print fulfillment via independent booksellers, deep behavioral reading metrics, and open AI agent connectivity, Readwise has delivered one of the most ambitious alternatives to legacy reading platforms in recent years.
