What is Readwise?

Readwise ships library-wide Ghostreader with tool-calling: tag, annotate, save across your full archive

Readwise is in an aggressive capability expansion phase centered on its Ghostreader AI layer. The August 7 release shipped Global Ghostreader — AI that searches, tags, annotates, and manages the full user library with granular per-tool permission controls. This followed Readwise 2.0, a complete mobile app rebuild. The team ships meaningful changes at a weekly cadence while simultaneously expanding integration depth across Kindle, Kobo, Twitter, and the MCP server.

What is AFFiNE?

AFFiNE ships stable iOS Share Extension imports while patching editor correctness and selfhost deployment

AFFiNE is releasing daily canary builds that advance the iOS client (Share Extension now stable, share-to-support in prior weeks) alongside editor reliability fixes — heading preservation in readonly mode and priority queue correctness in the block editor. Selfhost deployment is also receiving correctness fixes, indicating the self-hosted user base is growing.

Readwise ships library-wide Ghostreader with tool-calling: tag, annotate, save across your full archive

◆ Current state

Readwise is in an aggressive capability expansion phase centered on its Ghostreader AI layer. The August 7 release shipped Global Ghostreader — AI that searches, tags, annotates, and manages the full user library with granular per-tool permission controls. This followed Readwise 2.0, a complete mobile app rebuild. The team ships meaningful changes at a weekly cadence while simultaneously expanding integration depth across Kindle, Kobo, Twitter, and the MCP server.

◆ Where it's heading

Readwise is converting its reading archive into an AI-native knowledge management platform. The move from per-document AI to library-wide AI with tool-calling puts it in direct competition with Notion AI and Mem — but with a moat in years of accumulated highlights and reading history those tools can't replicate. Subsequent releases have been tightening integration quality (Kindle, OpenAI keys, Ghostreader targeting) and expanding mobile parity rather than adding new AI surface.

◆ Prediction

Mobile-native Global Ghostreader tools are the likely next move — library-wide AI tools currently require web or desktop, while mobile chat only recently launched. Completion of that convergence would unify the platform's AI story across every surface.

AFFiNE ships stable iOS Share Extension imports while patching editor correctness and selfhost deployment

◆ Current state

AFFiNE is releasing daily canary builds that advance the iOS client (Share Extension now stable, share-to-support in prior weeks) alongside editor reliability fixes — heading preservation in readonly mode and priority queue correctness in the block editor. Selfhost deployment is also receiving correctness fixes, indicating the self-hosted user base is growing.

◆ Where it's heading

The consistent mobile investment suggests AFFiNE is treating iOS as a primary platform, not a secondary one. The canary cadence will harden into stable releases as mobile features reach parity; the selfhost fixes indicate a parallel push toward enterprise self-deployment alongside the consumer cloud offering.

◆ Prediction

The next stable release will consolidate iOS Share Extension improvements; given the concurrent account-switching work, a meaningful update to multi-account or team collaboration workflows seems likely.
