Tinfoil

Tinfoil Private Chat is an AI‑driven messaging interface that runs locally and connects to open‑source language models. It processes user input and generates responses without sending data to external services, aiming to keep every exchange confidential. The application also exposes an API, allowing developers to integrate the same private chat capabilities into their own tools or workflows.

The software targets users who require secure, private conversational AI, such as individuals handling sensitive information or organizations that must comply with strict data‑privacy policies. By supporting open‑source models, it gives users the flexibility to choose the underlying AI engine that best fits their needs while maintaining full control over the execution environment.

What distinguishes Tinfoil is its explicit focus on verifiable privacy: all processing occurs on the user’s machine, and no network calls are made to third‑party servers unless the user explicitly configures them. This design choice makes it suitable for experimental deployments where data confidentiality is a primary concern.
