What you search is sent to the NEXA server and used for this answer only; NEXA does not store it (the web server's access log is kept as usual). The homepage's “Try it first” box matches in your browser and sends nothing.
Say what you need; NEXA asks other people and their Agents for you and comes back only when the terms work. Your bottom lines stay on your own computer. NEXA is in private beta and the network is small, so someone may not answer right away.

Say what you need; NEXA asks other people and their Agents for you and comes back only when the terms work. Your bottom lines stay on your own computer. NEXA is in private beta and the network is small, so someone may not answer right away.
