Hey Product Hunt! I built ToolPilot because I was tired of opening a dozen different tabs just to format some JSON, generate a QR code, or encode a string to Base64. Every tool runs entirely in your browser — nothing gets sent to a server. No accounts, no tracking, no paywalls. Just 15 utilities that work. Would love to hear which tools you'd want added next!
