Joplin vs Readwise
A side-by-side editorial comparison of Joplin and Readwise — release velocity, themes, recent moves, and the top alternatives to consider.
Joplin vs Readwise: at a glance
What is Joplin?
Joplin 3.7 ships AI chat, semantic search, and MCP integration — all off by default, all controllable by the user.
Joplin 3.7 is the product's first real AI release: an in-app chat panel for querying the currently open note, semantic (meaning-based) search across notebooks, and an MCP server that lets external AI assistants connect to Joplin's note graph. The implementation is privacy-first by design — AI is disabled by default, local models (Ollama, LM Studio) are explicitly supported, and cloud AI services only receive the specific note content relevant to a request rather than the full notebook. A companion documentation post published September 14 lays out the privacy model explicitly.
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.

Joplin 3.7 ships AI chat, semantic search, and MCP integration — all off by default, all controllable by the user.
◆ Current state
Joplin 3.7 is the product's first real AI release: an in-app chat panel for querying the currently open note, semantic (meaning-based) search across notebooks, and an MCP server that lets external AI assistants connect to Joplin's note graph. The implementation is privacy-first by design — AI is disabled by default, local models (Ollama, LM Studio) are explicitly supported, and cloud AI services only receive the specific note content relevant to a request rather than the full notebook. A companion documentation post published September 14 lays out the privacy model explicitly.
◆ Where it's heading
Joplin is repositioning from a sync-agnostic note-taking app into an AI-native knowledge base, differentiated by opt-in, local-first controls. The HMD Terra M preload partnership and the warrant canary point to a deliberate push toward privacy-conscious enterprise and professional users who distrust cloud-first tools. The MCP integration is particularly strategic: it makes Joplin's note graph accessible to external orchestration pipelines without locking into any particular AI provider.
◆ Prediction
The next major release will likely expand AI chat to multi-note context — currently limited to the open note — and add more configurable MCP tools. The HTR (handwritten text recognition) project from the 2024 French government partnership is also likely to appear in a near-term release.

5.0COLLAB
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.
