Every bot detection system I've seen works with two actors: human or bot. Block the bot, let the human through.

That model is wrong in 2026.

There is a third actor: AI agents acting legitimately on behalf of real users. Shopping assistants. Automated onboarding flows. Fintech integrations. These agents look like bots by every traditional signal: headless browser characteristics, scripted input patterns, no idle pauses. But blocking them means turning away real business.

I built Nyasa to handle all three.

Why existing tools fail now
