Nuclino vs Readwise: at a glance
What is Nuclino?
Nuclino's October drop turns to mobile and content blocks after three MCP-focused releases.
Nuclino ships a feature roundup roughly every quarter. The October 26 release covers mobile app improvements, more highlight colors and audio blocks; the feed carries only the title, so details aren't visible. The three releases before it, January through September, each extended its MCP server and API access for AI assistants.
What is Readwise?
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.

Nuclino's October drop turns to mobile and content blocks after three MCP-focused releases.
◆ Current state
Nuclino ships a feature roundup roughly every quarter. The October 26 release covers mobile app improvements, more highlight colors and audio blocks; the feed carries only the title, so details aren't visible. The three releases before it, January through September, each extended its MCP server and API access for AI assistants.
◆ Where it's heading
After a year where MCP access was the recurring thread, the latest drop goes back to editor and mobile basics. Nuclino looks to alternate between the AI-assistant access layer and core editing features rather than going all-in on either.
◆ Prediction
The quarterly rhythm points to the next roundup around late January 2027. Whether MCP returns as a headline item there is unclear from these entries.
Readwise
6.3COLLAB
Readwise launches Books, its own ebook store and reading app, a week after unbundling.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
Expect weekly Books fixes and Kindle-import work, and a move from invite-only to open signup if the store holds up.
