What is Mattermost?

Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.

Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.

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.

Mattermost vs Readwise: editorial side-by-side

M6.3

Mattermost v12.1 puts bots and burn-after-reading messages under the same access rules.

◆ Current state

Mattermost v12 shipped in parts: agents limited to the requesting user's access, Cross Guard for transfers across security domains, and user, device and channel attributes in access policy. A November 9 partnership pairs v12 with Arqit's quantum-safe device trust. v12.1 on November 13 extends attribute-based access control to bot accounts and to Burn-on-Read permissions, and Desktop v6.4 fixes Boards on subpath deployments.

◆ Where it's heading

Each release closes another gap in one policy model for who and what can see a message: people, devices, channels, and now automation accounts and ephemeral messages. The audience stays defence and regulated buyers, and point releases are filling in v12 rather than starting new lines.

◆ Prediction

Further v12.x releases likely apply the same attribute rules to more objects, such as files, plugins or AI agent actions, following the pattern of v12.1.

6.3

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.
