Interact opens its intranet to outside AI assistants and uses Claude to attack its own platform.
A side-by-side editorial comparison of Readwise and Tella — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Tella adds a Free plan, redesigns the editor, and broadens distribution into Intercom and beyond.
Tella is in a sustained editor-polish-plus-distribution cycle. The big change: a Free plan now sits alongside Pro, paired with an in-product AI support assistant. The editor was redesigned with a left-side toolbar, lighter UI, and a new transcript sidebar. New layouts (50/50 split) and finer camera-bubble positioning (3×3 grid plus three sizes across orientations) give creators more compositional control. Distribution widens with an Intercom Help Center integration and a refreshed tella.com.

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.

The product is leaning into accessible-funnel-plus-creative-control: lower the barrier to start (Free plan), make the editor look modern and inviting, and embed videos where customers already are (Intercom). View notification controls and webhook events for viewer activity hint at an upcoming push toward integration-ready video analytics.
Expect more distribution surfaces (Slack, Notion-style embeds beyond Intercom) and AI features beyond the support assistant — likely auto-chapters, B-roll generation, or transcript-driven editing. The Free plan likely drives an experimentation phase before the next pricing/packaging tightening.
