Kapitol.ai

Kapitol.ai is an analytics tool that tracks US Congress stock trades and scores insider signals. Kapitol.ai is a platform that tracks stock trades by US Congress members, scores each by insider-signal strength and sends alerts, with an in-house scraper, scoring engine and dashboard.

Kapitol.ai is a platform that follows the stock transactions made by members of the US Congress and turns them into something a retail investor can act on. Instead of leaving users to read raw disclosure filings, it collects the trades as they appear, rates each one by how strongly it looks like an insider signal, and surfaces the results in a dashboard. The idea behind it is simple: if lawmakers trade ahead of policy, their activity is worth watching, and the "smart money" can be followed with less manual effort. The product is built and run by Tijn Knapen, a Dutch full-stack developer who lists it among his own products alongside a web agency and a wallpaper app. According to his portfolio, Kapitol.ai was started in 2026 and is live. The stack named for the project is Next.js, Python and PostgreSQL, with scraping as a core ingredient. The scraper, the scoring logic and the dashboard are all written in-house, which means the signal ranking reflects one developer's own methodology rather than a licensed data feed. In practice, the workflow centers on three pieces. A scraper pulls in congressional trades, a scoring layer assigns each transaction a signal strength, and an alert system notifies users so they do not have to check the dashboard constantly. This suits individual investors, newsletter writers and hobbyist researchers who want a lightweight way to monitor political trading activity without building their own pipeline. Among alternatives, it sits in the same space as congressional trading trackers and general stock research dashboards. Its distinguishing feature is the emphasis on a signal score and push-style alerts rather than a plain table of filings. Buyers should note that the homepage used for this listing is the creator's personal portfolio, so details such as pricing, plans, data coverage and refresh frequency are not spelled out there and should be confirmed on the product's own site before relying on it for investment decisions. It is a research aid, not financial advice.
