Kepler is a tool designed to help individuals and teams transform saved web content into structured, reusable digital memory. It addresses the challenge of turning scattered links, pages, videos, and other online references into organized resources that retain their original context, making them more useful than traditional bookmarks. Kepler also supports integrating this contextual memory with AI tools, allowing AI agents to answer questions and take actions with enhanced context from a user's collected web activity.
The platform enables users to capture links, pages, videos, and references in a single click, preserving the context behind each save. Kepler organizes these saves into spaces, which can be used for both personal and team memory management. It offers a distinction between basic link captures, which store surface details such as a webpage's title or a YouTube video's description, and deep Summaries, which extract more comprehensive data like full transcripts, lengthy PDFs, or images. These Summaries are processed into optimized memory artifacts for use with AI tools. Users can access Kepler through a browser extension and a mobile application, and can manage their memory, spaces, and AI context within the platform.
Kepler is designed to enhance the performance of external AI services by providing them with the user's contextualized memory. It can be connected to AI tools such as ChatGPT or Claude via MCP, and the service does not charge for these integrations. The platform operates on a credit-based system for its built-in AI assistant and deep Summary features, while basic link captures remain unlimited across all tiers. Advanced Memory Search is available on the Pro tier, enabling deeper and richer context retrieval for queries, while all tiers use the user's memory to ground AI-generated answers.
For organizations, Kepler offers an Enterprise plan that includes shared memory, premium connectors, security controls, custom review processes, and dedicated support. The tool is developed by Momentium Pty Ltd. Users retain ownership of their saved links, annotations, and memory graph regardless of their subscription tier.
In the Read-it-later & curation space, Kepler takes a focused approach. It focuses on organizing and retrieving saved web content and activity for personal or team use. Kepler is a consumer product aimed at knowledge workers. There is a free tier, and paid plans start at $10. Kepler is available on the web, iOS, Android, embeddable surfaces, and macOS.
Momentium Pty Ltd builds and maintains Kepler, and the product first shipped in 2025. Among its 8 catalogued features are link saving, web activity capture, and team spaces.
