MyExternalCortex

An AI coach for people with ADHD — built around how ADHD brains actually work.

What it is

MyExternalCortex is a personal assistant and coach that lives where you already are — Discord and Telegram — so there's no new app to learn.

You talk to it like a person. It remembers your tasks, sends you reminders, asks how your morning went, and gently helps you build the habits that research shows actually move the needle for ADHD brains.

It doesn't nag. It doesn't guilt you for snoozing the same task five times. It just helps you move forward.

What it does

  • Task and appointment management — add anything in plain language, get reminded at the right time
  • Daily check-ins — a quick morning orientation: what's on your plate, what's the one thing that matters today
  • Habit coaching — evidence-based habits introduced one at a time, tracked with no judgment
  • Urgency that actually escalates — recurring tasks you keep missing get gently louder over time
  • Wins tracking — every completed task counts; the bot remembers

Try it live

The best way to understand MyExternalCortex is to have a conversation with Aria — the AI coach at the heart of the system.

See how it works

No account required — just start talking. You're chatting with a real AI running on the same system real users use, with a sample task list already loaded. Ask what's on your list, tell it you finished something, ask it to help you plan your afternoon.

The demo is a shared account, so other visitors see the same conversation history. Your own data is private once you sign up.

If the window doesn't appear, your browser may have blocked the popup — look for a notification in the address bar and allow it.
