I built Investment Brain because researching a single stock properly takes way too long: reading filings, digging through financials, checking recent news, and trying to build a real bull/bear case from scattered sources. Most tools either dump raw data on you, hide useful research behind expensive subscriptions, or give you AI answers without showing enough of the evidence. Investment Brain is an AI-powered stock research workspace. Search a company, and it pulls together key financials, recent news, SEC filings, an AI-generated research report, source-backed takeaways, and a chat assistant so you can ask follow-up questions without starting from scratch. It’s not a stock picker or financial advisor. The goal is to help you understand a company faster while still showing the data and reasoning behind the analysis. It’s free to start, and I’d genuinely love feedback from people who research their own investments. What’s the one part of your research process you wish you could automate? I’ll be in the comments all day.
