A new conversation starts from zero. A second AI assistant cannot see what the first did. The Contigi “Second Brain” fixes both: a logbook every session writes to, a daily brief compiled from it and one set of rules, so each is aware of what the others did and nothing is repeated or lost.
Each AI assistant writes its own diary, one dated entry per piece of work, in its own file. one writer per file, so nothing is ever overwritten.
Every morning one AI assistant reads every diary and rewrites one screen every session reads first: what happened, what is open, who owes what.
How you like things done lives in skill files, one per job, so a rule changed once is changed in every conversation.
Every job an AI assistant finishes ends with a diary line. We patch this into every skill where a job can end, because a diary step written in only one place is the step that gets skipped.
So the daily read stays cheap as the year grows.
My own team of 19 AI assistants has run on exactly this since July 2026. The morning brief you would get is the same brief I read at 7am. The closing-step lesson above cost me 7 days of missing entries before I found it; you get it on day one.
Requires at least one AI assistant already in place. If you have none yet, start with First Hire Basic.
