About IO Tools 3.0 (Revamp)
IO Tools is a free tools platform - 900+ utilities for everyday tasks, no signup needed. 3.0 is a full rebuild: redesigned UI, faster load times across the board, and a public API + MCP server so you can plug IO Tools straight into your AI agent workflows instead of opening a browser tab. We've grown from ~40 to 700+ daily clicks. This release is about making that same toolkit usable anywhere - browser, API, or agent.
