What is Outline?
Outline adds personal docs even admins can't open, pairing agent access with user privacy.
Outline ships on two tracks: an agent integration surface (April's MCP editing tools, September's browser-native WebMCP) and steady workspace UX work. The October release gives every member a Personal sidebar section for drafts and notes that no one else can see, admins included. That is a notable stance for a team wiki, where admin visibility is usually the default.
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.

Outline

◆ Current state
Outline ships on two tracks: an agent integration surface (April's MCP editing tools, September's browser-native WebMCP) and steady workspace UX work. The October release gives every member a Personal sidebar section for drafts and notes that no one else can see, admins included. That is a notable stance for a team wiki, where admin visibility is usually the default.
◆ Where it's heading
Outline is building toward an agent-accessible knowledge base that individuals also use for private work, not only shared documentation. MCP and WebMCP opened the content to agents, Open Knowledge Format export lowered lock-in, and personal documents pull pre-publication drafting into the product. The pattern is to widen what lives in Outline while giving users clear control over who, or what, can reach it.
◆ Prediction
The next likely move is connecting personal documents to the existing flows, for example promoting a personal draft into a shared collection or defining what the MCP tools can see in personal space. The entries don't show how agent access and personal privacy will interact, and that is the open question.
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.
