About Cortexial

Cortexial is a hosted chat workspace that lets you talk to several AI models in a single thread. You can change the active model at any message while the conversation history carries over, or use a parallel mode that asks every model the same question and shows the answers side by side for comparison.

Privacy is the main differentiator: messages are automatically masked for personally identifiable information, so sensitive details such as names are not sent to any model provider. The workspace also offers projects and folders for organizing conversations, plus a knowledge base where you upload documents such as reports, code, notes and PDFs to ground answers in your own data. Sign-in is with Google.

Cortexial is a commercial closed-source service with a free tier that needs no credit card, and further plans are listed in a pricing section. There is no self-hosted version.
