TESS AI

TESS AI is an autonomous AI workspace that combines 250+ leading models, including GPT, Claude, and Gemini, into one platform built for professionals who want complex tasks completed with minimal manual work.

TESS AI is a multi-model AI platform designed for professionals and businesses that want more than a basic chatbot. The platform combines access to more than 250 AI models, including GPT, Claude, Gemini, and several specialist tools, inside a single workspace built around autonomous task execution.

The main appeal is how much work TESS can handle without constant supervision. You can assign large projects like market research, competitive analysis, long-form content creation, presentations, internal documentation, or workflow automation, then allow the platform’s AI agents to complete the process independently. Tasks can include web research, tool usage, revisions, and multi-step reasoning before a final output is delivered.

One of the more interesting features is Model Council 6.1, where multiple AI models collaborate on the same request to improve quality and reduce the weak spots that often appear when relying on a single model alone. TESS also supports extended context windows through Max Mode, allowing massive documents and datasets to be processed in a single workflow.

The platform is clearly positioned for companies exploring broader AI adoption without adding multiple subscriptions across different vendors.

One workspace connecting GPT, Claude, Gemini, and hundreds of additional models.
