# Nexus Call Screening > AI call screening for Android and iPhone, made by Noah, a solo developer in North Carolina. People in your contacts ring like normal. Most callers you don't know talk to an automated assistant that asks who's calling and why; real callers are put through or leave a voicemail you can read as text; numbers on the spam list are refused. Calls with no caller ID are refused. Phone calls only, not texts. Invite-only wait list. Current price and free-trial terms: https://nexus.noahs.world/waitlist People in your contacts always ring and are never blocked. Callers are told the call is screened and may be transcribed, and Anthropic's Claude reads what they say to decide what to do with the call. The spam list is numbers caught on more than one member's line plus numbers from public FTC complaints, and only the number is shared. Nexus works through your carrier's call forwarding to a separate Nexus number that's included, so you keep your own number and carrier. The Android app is installed from the Nexus website, not Google Play. Billing is through Stripe, and members can cancel themselves any time under Account. The person running Nexus can't read members' voicemail or hear what callers said. ## About - [About, pricing, refunds, privacy](https://nexus.noahs.world/about) - [Join the wait list](https://nexus.noahs.world/waitlist) - [How to cancel and turn Nexus off](https://nexus.noahs.world/cancel) ## Scam call answers - [Scam calls, answered](https://nexus.noahs.world/scam-call-faq): Plain answers to common questions about scam and robocalls: why they look local, why there's silence when you answer, what to do if you slipped, and how Nexus screens them for you. - [Why scam calls show your own area code](https://nexus.noahs.world/neighbor-spoofing): Why scam calls look like they come from your area code, or even your own number.
