Kalpa is a read-it-later platform designed to help users capture, organize, and rediscover online content such as articles, videos, social media threads, academic papers, and more. The tool addresses the common problem of forgetting saved links or struggling to locate key information by leveraging AI to extract, summarize, and connect knowledge from saved resources. Its knowledge graph visualizes relationships between saved items, allowing users to see patterns and connections that might otherwise remain hidden.
Key features include AI-generated summaries in multiple styles, automated tagging using the user's own vocabulary, entity extraction, and discovery of related content. For videos, Kalpa provides full transcript extraction, searchable transcripts, AI-identified key moments, timestamp deep links, and metadata such as channel and duration. Users can save content with a single click via a browser extension, which is available for Chrome, Chromium-based browsers (such as Edge, Brave, and Arc), and Firefox. The platform supports saving a wide variety of web content, including articles, YouTube videos, Twitter threads, academic papers (with DOI lookup), and CodePen demos.
Kalpa offers full-text and semantic search across all saved items, helping users quickly find information or revisit specific moments in videos. The concept of "Universes" allows for flexible, interest-based collections, with saves assignable to multiple Universes and AI suggestions for organization. Users can export their data at any time in standard formats such as JSON and Markdown, supporting data portability and avoiding vendor lock-in. Collections and knowledge structures can be shared, and the browser extension ensures frictionless capture of content.
The platform is currently in private beta, accessible by joining a waitlist and participating in small user cohorts. Kalpa is offered as a paid service with a single pricing plan: $99 per year or $12 per month, including unlimited saved items, AI-powered features, unlimited Universes, full-text search, browser extension, data export, and priority support. A 30-day money-back guarantee is available. The tool is positioned for knowledge workers, researchers, and anyone seeking to organize and connect their online learning and discoveries.
In the Read-it-later & curation space, Kalpa takes a focused approach. It focuses on losing track of saved links and struggling to organize and retrieve online content efficiently. It is built as a consumer product for knowledge workers. It runs on the web, embeddable surfaces, and API.
Kalpa first shipped in 2025. Key capabilities include AI summaries, knowledge graph, and video transcripts. Kalpa is currently in beta.
