Cortical is a new AI tools platform built by TIZZLE.
It is designed around a simple idea: use the AI models you already pay for, inside tools that stay free.
No extra subscription. No locked-down credits. No unnecessary platform fee.
You can try it now at cortical.tizzle.org.
Why TIZZLE built Cortical
AI tools are useful, but a lot of them are priced like closed platforms.
You pay for the model.
Then you pay again for the wrapper around it.
Cortical takes a different approach.
Instead of charging another subscription, Cortical lets users bring their own API key from providers like OpenAI, Anthropic, Google, or other supported model providers.
The goal is simple:
- keep the tools free
- let users control their own model access
- avoid unnecessary platform fees
- build clean interfaces for real work
- keep improving toward native Cortical models over time
Cortical is not just another chatbot wrapper.
It is the start of a wider AI product and research layer inside the TIZZLE ecosystem.
What Cortical is
Cortical is an AI platform focused on free, bring-your-own-key tools.
The first products include Cortical Chat and Cortical Code.
Cortical Chat is a clean AI chatbot interface where users can connect their own API key and start chatting without paying Cortical a usage fee.
Cortical Code is a terminal coding agent designed to work inside real projects. It can read project structure, plan changes, write code, and help test updates while the user stays in control.
