Hi, I'm Heledd – Your Thinking Partner

Heledd Williams, late-diagnosed ADHD coach and founder of Arc ADHD AI.

After years of navigating my own ADHD arc, I now help others build gentle, sustainable systems that fit their unique brains.

Based in North Wales but working online worldwide, I offer bilingual support (English / Cymraeg) and a human-first approach enhanced by simple AI tools.

Whether you're seeking clarity as a late-diagnosed adult, workplace adjustments, or classroom strategies, I'm here to listen and support as an accredited ADHD coach – no judgement, just practical steps forward.

Who I Help

I offer warm, personalised ADHD support to adults whose brains simply need a different kind of gentle approach.

From late diagnosed ADHD women seeking clarity, to educators wanting effective ADHD inset day training, or HR teams building ADHD workplace accommodations – I can help create kind, neuro-affirming systems that fit ADHD brains naturally.

Late Diagnosed Women with ADHD

— Bex M, Hong Kong
"I have had the privilege of working with Heledd. She is caring and perceptive - I highly recommend her."

— R Taylor, Perth, Australia
"Heledd has helped me learn a tremendous amount about myself, particularly my strengths and challenges. Her ability to do this without judgment creates a safe space for exploration and growth."

— LS, Hong Kong
"I initially thought coaching wouldn’t be valuable for me since I didn’t have major problems. However, I learned that the small stuff can be harder to deal with, as it often creates bad habits and weak routines. Addressing these smaller issues set me up for success with bigger challenges, giving me a solid strategy and foundation."

— Teresa, Hong Kong
