Nessie

Nessie provides personal AI brains designed to enhance human cognition. It transforms scattered AI conversations and documents into a shareable AI brain that users own. Serving as a thinking partner, Nessie allows users to instantly search their entire history of ideas, synthesize them into new insights, and observe their knowledge evolve over time. Currently, many valuable ideas are confined to temporary AI chat histories. Nessie consolidates context from ChatGPT, Claude, and soon Apple Notes, Google Docs, Notion, and other sources, organizing them into an AI-enhanced brain. Nessie is also developing a sharing feature, enabling users to send dynamic AI brains, such as a "Product Strategy Brain" to a cofounder or a "Research Brain" for team collaboration. It targets AI-native thinkers like founders, researchers, and writers who value the compounding of their best ideas. Since its launch three weeks ago, Nessie has attracted over 1,200 users who have imported more than 300,000 AI conversations, experiencing a 30% week-over-week organic user growth. Nessie aims to establish a new medium for personal intelligence, where everyone can have an AI brain to think better, remember more, and share their knowledge with the world.
