When a campaign was one billboard planned a month ahead, "every creative passes legal" was a reasonable rule — I've worked inside those approval flows, and nothing shipped unseen. But that's not how ads work anymore: audiences are segmented to micro, A/B tests spin up new creatives daily, every variant carries its own claims — and you multiply that across dozens of ad accounts, plus affiliate accounts you don't even control.
Approve-each-one didn't get neglected; it got outgrown. In big structures the flow becomes the bottleneck everyone quietly routes around; in fast-moving companies it never exists at all. Either way, most creatives ship unseen — not because anyone is careless, but because nobody rebuilt the review step for the speed of testing.
Kouro is the intake layer I needed then: it screens every asset in seconds against the patterns platforms and regulators actually punish, and routes to a human only what deserves a human — with the rule and the precedent already attached.
It's not a lawyer, and it never pretends to be. For founders, it's the screening pass before the counsel call. For compliance teams, it decides what deserves you.
If a flag needs a law degree to understand, we've failed. Every issue is written for the person who has to fix it.

Kouro is screening software, not a lawyer. We flag patterns worth a second look — we never pretend to be legal sign-off.
航路 (kouro): a marine or air shipping route — the course or line a ship or aircraft is actually on, not just where it ends up. That's the name, taken plainly: not a verdict, a route. Every metaphor in the product — courses, flags, safe harbors — comes from the same place: helping you get where you're going without running aground.
