Cogni - Protect your brain from AI induced cognitive decline (backed by 10+ research papers)

Cogni is a Chrome extension that makes you think before the AI does. It's built on 10+ research papers on what heavy AI use does to original thinking, including work from Harvard, MIT, UPenn and Microsoft itself.

In one of the studies students given unlimited GPT scored worse once it was taken away. They felt no difference.

I started building it after scrolling back through my own ChatGPT history one evening. I was looking for an old prompt and instead found dozens where I'd asked the AI to generate things from scratch that should have started with me. Names, angles, opening lines, first drafts of ideas. I wasn't editing my own thinking. I'd stopped supplying any.

Cogni sits on top of your ChatGPT or Claude session and only steps in when you're about to let the AI supply the substance. Fixing your grammar goes straight through. Asking it to write the whole thing from scratch gets a pause first: what's the core point you want to make, in your own words? You give it a line, then the AI helps. The idea stays yours. Nothing leaves your browser and no prompt text is ever stored.
