your brain called. it wants backup.

Keep every little thought, forever

Cortex is a cozy second brain. Toss in notes, lists, and shower thoughts — it tidies up, links things together, and hands them back right when you need them.

call grandma — she mentioned that soup recipe

the best ideas show up in the shower. capture them after.

three tiny habits, one big memory

step 1

Jot it down

One tap, one thought. Cortex keeps the page always within reach — phone, laptop, watch.

step 2

Watch it connect

Your notes hold hands behind the scenes. Related thoughts find each other, no tags required.

step 3

Remember like magic

Ask “what was that gift idea for June?” and it’s there — the note, the date, the context.

“It feels less like an app and more like a very organized friend who never forgets anything I tell them.”
