Shareable AI Brains for Everyone
Hey everyone! We're Anna and Tiger – co-founders of Nessie.
TLDR: Nessie turns your scattered AI conversations into a personal knowledge base where you can search, ask questions, and surface new insights.
Many of us now think through AI conversations. Our most creative moments and deepest explorations happen in conversations with AI. Nessie is Perplexity for your mind, giving every AI conversation a permanent memory.
The Problem
Your best ideas are scattered.
Brilliant insights are buried in endless AI chat histories, impossible to find or build upon. Trying to connect an idea from last Tuesday’s chat with a note from today is a nightmare of copying, pasting, and losing context.
Your best ideas deserve to compound.
The Solution: A Home for Your Ideas

Nessie gives your ideas a home—a single, fluid space where your notes and AI conversations live together. It’s a thinking partner that effortlessly captures your insights, building a single, perfect memory of your ideas.
This lets you:
-
Build your personal knowledge base, effortlessly.
Import your entire ChatGPT history, or capture individual conversations that you don’t want to lose. Nessie automatically distills your conversations into structured notes, organized around topics you care about. Your existing ideas become a structured, searchable knowledge base without you lifting a finger.
-
Instantly find any idea.
Search across your entire knowledge base and unearth your most brilliant ideas in seconds. Never lose a thought to a messy chat history again.
-
Compound your best thinking.
Your knowledge base becomes a thinking partner. You can chat with a specific concept, a folder of notes, or your entire knowledge base to connect ideas and create new insights.
-
Own your mind.
We believe agency over your own thinking is critical, especially in the age of AI. Nessie gives you transparent control over your memory. Your knowledge is built from visible, editable notes that you can shape and delete at will. Everything is stored locally and privately on your device—no one can see it but you.
Who This Is For
Nessie is built for AI-native thinkers: the researchers, founders, VCs, and writers who are already using AI as a partner to develop and challenge their ideas. If you live in ChatGPT and feel its limitations every day, we built Nessie for you.
Our Vision
We are building your personal context layer for the AI age. Our vision is a future where your thinking compounds effortlessly, where no idea is ever lost, and your own knowledge becomes your most powerful tool.
About Us
We built Nessie for ourselves.
We met at Yale and bonded over our shared obsession with using AI to push the limits of our own thinking. We quickly hit a wall. Anna had several Gemini chats that crossed the 1M token context window—a massive limit for any major model today. The brilliant insights from those conversations are now effectively lost.
We felt constrained by tools that weren't built for the way we think, so we built the solution we needed.
We use Nessie every single day.
Our Ask
- Try Nessie and build your AI second brain. We are obsessed with feedback from fellow AI power users and would be honored to hear your honest thoughts.
- Follow our journey. We'll be sharing updates, behind-the-scenes, and our learnings as we build in public.
- Share with a friend. If you know another founder, researcher, or writer who lives in their AI chats and is constantly losing great ideas, we'd love for you to share Nessie with them.
