From a YouTube video to queryable conviction
Paste a video or article — InvestorBrain transcribes it, extracts companies, theses, catalysts and biases into a living knowledge graph. It remembers who said what, so contradictions surface instead of hiding in your watch history.
A complete memory layer for your investment research. Every source you feed it becomes structured, connected, and permanently queryable.
Get Started↗Living Knowledge Graph
Every video, article and note becomes typed nodes and edges — companies, theses, catalysts, creators — merged into one connected memory.
Contradiction Detection
When one creator's bull case collides with another's bear case, the graph flags it. Red edges mean someone is wrong — find out who.
Creator Bias Profiles
Permabulls and permabears reveal themselves over time. InvestorBrain tracks who said what, when, and how it aged.
Ask Your Memory
Natural-language answers grounded in your own research trail. Bull case vs bear case, catalysts due this quarter, how your view evolved.
