NOWSLETTER is a collaborative tool designed to help individuals and small groups gather and organize event information from newsletters. It addresses the challenge of extracting useful, structured data from the often messy and decentralized format of email newsletters, which are commonly used in local or niche communities to share events. The tool is particularly suited for users who are connected to the people sending the newsletters, enabling a more personal and context-aware approach to event collection.
The platform operates by presenting a split view interface: the original newsletter appears on one side, while the extracted events—initially proposed by a local AI model—are displayed on the other. Both the administrator and newsletter authors can review and edit the extracted events, allowing for collaborative curation without the need for explicit communication about every change. The workflow combines AI-generated suggestions with human oversight, ensuring that the final event listings accurately reflect the sender's intent and the collector's needs. The AI used for extraction runs locally, which allows users to monitor energy consumption and avoids reliance on third-party AI services, thereby addressing privacy and ethical considerations.
NOWSLETTER is open source, and users can choose to run the tool themselves or request assistance from the creator. The system is designed to be accessible to individuals who subscribe to newsletters and wish to maintain an up-to-date overview of local events, especially in contexts where larger platforms or automated scraping are impractical or undesirable. The tool also supports potential publication of collected events to other platforms or protocols, such as Mastodon, Bluesky, ActivityPub, ATproto, Gancio, or Mobilizon, though this is presented as a future possibility rather than a current feature.
By focusing on newsletters as a decentralized and context-specific source of information, NOWSLETTER offers a method for event collection that prioritizes consent, transparency, and collaboration. Its open-source nature and reliance on local AI further distinguish it as a privacy-conscious solution for managing event data from email newsletters.
In the Productivity & Work space, NOWSLETTER takes a focused approach. It focuses on collecting and organizing event information from multiple newsletters efficiently. It is built as a consumer product for newsletter readers and event organizers. NOWSLETTER is free to use. The product ships for the web.
Joel builds and maintains NOWSLETTER, and the product first shipped in 2026. Development happens publicly on GitHub with 37 commits in the last 90 days. Key capabilities include newsletter parsing, event extraction, and collaborative editing.
