Things I actually use or recommend. Every link opens somewhere else — nothing here is mine to sell, and the list stays short on purpose.
Books
Six worth your time. If you are newly diagnosed, start with the first one in each pair.

Driven to Distraction
Edward Hallowell & John Ratey
The book most people are handed after a late diagnosis. Explains what ADHD actually is, without the shame.
BookADHD
Scattered Minds
Gabor Mate
Looks at ADHD through development and environment rather than deficit. Useful if the standard framing never fit you.
BookADHD
Unmasking Autism
Devon Price
On the cost of masking and what happens when you stop. The clearest book on late-diagnosed autism in adults.
BookAutism
Your Brain's Not Broken
Tamara Rosier
Practical, emotion-first. Deals with the shame spiral and the crash after hyperfocus.
BookADHD
How to Keep House While Drowning
KC Davis
Short, kind, and the best thing written on functioning during low-capacity weeks.
BookCapacity
Company of One
Paul Jarvis
The case for staying deliberately small. A useful counterweight when everyone tells you to scale.
BookBusiness

Software that assumes your capacity changes day to day. Most have a free tier, so try before paying.

Fast enough to catch a thought before it is gone. Type it in plain language and it files itself.

Time made visible
Block the work, not just the meetings. Seeing the day laid out is the cheapest fix for time blindness.

Focus audio
Functional music built for sustained attention. Works when lyrics do not.
PaidFocus
Notion
Second brain
Flexible enough to hold your systems in one place. Also flexible enough to become a procrastination project, so start small.
Free tierSystems
