PrivateGPT

Okara is a privacy-first AI workspace and private chat platform that lets professionals interact with 20+ powerful open source AI language and image models in one unified environment without losing context as you switch between models, conduct research, generate content, or analyze documents. All conversations, uploads (PDF, DOCX, spreadsheets, images), and workspace memory are encrypted at rest, processed on privately hosted open-source models, and never used for AI training or shared with third parties, giving users full data control with client-side key generation and true deletion. Okara combines secure, encrypted AI chat with integrated real-time web, Reddit, X/Twitter, and YouTube search tools, unified memory across models, and image generation, letting users weave live information and visuals into workflows while protecting sensitive or confidential data. It also supports shared team workspaces, enabling collaborative AI threads and shared context for groups like startups.

Tinfoil is a verifiably private AI platform built to deliver zero-trust, zero-data-retention inference by running open-source or custom models inside secure hardware enclaves in the cloud, giving you the data-privacy assurances of on-premises systems with the scalability and convenience of the cloud. All user inputs and inference operations are processed in confidential-computing environments so that no one, not even Tinfoil or the cloud provider, can access or retain your data. It supports private chat, private data analysis, user-trained fine-tuning, and an OpenAI-compatible inference API, covers workloads such as AI agents, private content moderation, and proprietary code models, and provides features like public verification of enclave attestation, “provable zero data access,” and full compatibility with major open source models.
