👋 Hey Product Hunt! I built InvestJournal because my process was scattered across spreadsheets, broker tabs and a Notes app I never reopened. I'd do real research on a company, form a thesis… and six months later have no record of why I bought it. The part I'd start with: it connects to Claude. Not a chatbot bolted onto a finance app — the opposite. InvestJournal exposes 66 tools over your own data, so you can stay in Claude and say things like: - "Rank my watchlist by return on equity." - "What did I say about CNR when I bought it?" - "Log 40 shares of ATD at $78.20 in my RRSP." - "Which of my holdings trade below the fair value I calculated?" - "Who on my list reports this week?" It reads and writes. Claude can add a stock, write a thesis, record a transaction, set an alert or put a task on your list — against the same data the web app shows. Setup is a two-minute flow at investjournal.io/connect. What it's connected to: 🧮 Reverse-DCF valuations — instead of guessing a fair price, see what growth the current price already implies. It turns "is this expensive?" into a question you can actually answer, and your holdings are priced against your number, not an analyst's. 📓 A thesis journal — the bull case, the bear case, and what would change your mind, with full revision history so you can watch your own reasoning move. 🌅 A morning desk — Home is a ranked list of what needs your judgment today: a holding that crossed your fair value, a company that just reported, a thesis you said you'd revisit. Not a feed. 📅 An earnings calendar — only dates the companies themselves announced, never an estimate, for the names you follow. 💼 Portfolio — transactions, cost basis, unrealized P&L, several accounts, cash included and currencies kept apart. 📊 Watchlists, ratios and alerts — with per-stock grading thresholds you set yourself, because "good ROE" isn't the same number for a bank and a software company. 📰 News — a public feed plus notifications for the companies you actually follow. On the web, on iOS, on macOS and on Android, in English and in French. Free to start. Everything above is free with one portfolio. Pro is C$25 a month (Canada and the US for now): the margin of safety between today's price and your own fair value on every portfolio row, up to five portfolios, fair-value alerts and a screener over the whole universe. Cancel any time. I'd genuinely love your feedback — what's missing from your own investing workflow? I'm reading and replying to every comment today. 🙏 (Not investment advice — a research and journaling tool, not a recommendation engine.)
