The Gap
Your brain runs 3 projects. Your attention only reaches 1.
Every professional carries unfinished work — pitch decks forming on the commute, client strategies crystallizing between site visits, product specs assembling across meetings. The thinking happens everywhere. But without a channel, the value leaks before a single deliverable lands.
Lost throughput
of thinking for the projects you can't attend to. The output is already happening — in cabs, walks, between meetings.

Tessera routes.
A task lands on your action list. A thinking fragment compounds into the right Folio. You don't classify. You don't tag. The system knows which project this belongs to.

Folios grow.
When you finally sit down, the cold start vanishes. The thinking you did across the week already lives here — grown into a structured deliverable. Review it. Edit it. Ship it.
