Readwise launches Books, its own ebook store and reading app, a week after unbundling.
Readwise now sells three products. A week after splitting Reader and Highlights into separate plans, it launched Readwise Books on October 30: an iOS and Android ebook store and reading app stocked by the major publishers, with reading sessions, following other readers, and Kindle and Goodreads imports. The same release added 13 Books tools to the Readwise MCP server, moved podcast transcripts onto the YouTube cleanup pipeline, and lets the Reader API set reading progress.
Tango ships an MCP server, so AI assistants can answer from a team's captured workflows.
Tango captures browser workflows into step-by-step guides, and the Tango MCP, now live on Enterprise plans, lets teams query their Tango workspace from inside AI assistants. Before it, 2026 releases deepened the guide itself: voice narration during capture, branching, translations, video embeds, plus a September rebrand and edit-mode shortcuts.

Readwise is moving from a layer on top of other people's reading apps to owning the purchase and the reading itself. The unbundle, the free Books app and the shared MCP server point to separate entry products that all feed the same account. Reader keeps its weekly cadence of TTS, transcript and parsing work underneath.
Expect weekly Books fixes and Kindle-import work, and a move from invite-only to open signup if the store holds up.

Before it, 2026 releases deepened the guide itself: voice narration during capture, branching, translations, video embeds, plus a September rebrand and edit-mode shortcuts.
The MCP changes where Tango's content gets read: guides become a knowledge source for AI tools, not only pages people open. It is the first AI move in the feed since the April 2025 AI CRM Admin agent, and again gated to Enterprise, where governance and translations also landed.
The entry is short on scope, so it is unclear whether the MCP is read-only; a follow-up widening it to more plans or adding write actions such as creating guides would be the next signal.
