What We're Building at ToolPort

At ToolPort, we're working on bringing more AI-powered tools directly to your browser — with a focus on privacy-first processing. Our existing tools demonstrate this approach:

We're currently surveying users to decide which AI tools to build next. Vote for the AI tools you want most — your feedback directly influences our development roadmap.

The Privacy Problem with AI Tools

Most AI tools require you to upload data to cloud servers, create accounts, and accept broad data usage terms. At ToolPort, we believe AI tools should be:

  • Local-first — process data in your browser when possible
  • Transparent — clear about what data goes where
  • No account required — just open and use
  • No data retention — your data is not stored or used for training
