Who's buying NVIDIA? What did the CEO just sell? Which chipmakers are growing fastest? Ask in Claude, ChatGPT or on the web, and get the answer straight from SEC filings, every number linked to its source. 220 AI & chip stocks. Free, no account, no API key.

Hi Product Hunt! Funds, insiders and big shareholders must tell the SEC what they own. It's all public, and it's nearly impossible to read: thousands of 13F tables, Schedules 13D/G, Forms 4, XBRL statements. Silicon Floor reads them for you, for 220 AI and semiconductor stocks, so you can just ask: • Who's buying NVIDIA, and who's selling? • What does the CEO really own? Shares, restricted stock, options. • Is TSMC growing faster than NVIDIA? Margins side by side. • What changed this week? Earnings, insider buys, new 5% stakes. Use it on the web, or ask from Claude or ChatGPT: Silicon Floor is in Claude's connector directory, or add https://siliconfloor.com/mcp as a custom connector. No account, no API key, free. Every number carries its date and its source, and SEC figures link to the filing itself, so you can check anything in one click. Missing data shows up as missing, never guessed. What stock or question should we add next?
