Relay - by King & Friends

Let AI do the talking, you do the thinking.

Relay gives you and one other person one AI in common — an "AI hatchling" that lives between the two of you. You both know it's there, you both talk to it, and it comes to understand you both.

That position lets it do real work. It remembers what each of you has told it, so nothing starts from zero. It turns what you mean into what to say, so writing well stops depending on having the words. And because it knows you both, it gets your meaning across right the first time.

Use it with your mom, an old friend, your boss, a mentor, someone far away — any relationship that deserves better upkeep than a busy week allows.

Every relationship gets its own hatchling.

HOW RELAY WORKS

1. Sign in with your phone number.
2. Add someone by their phone number to hatch a shared AI just for the two of you.
3. When they accept, your hatchling comes to life — shared between you both.
4. Text it, call it, or ask it to carry a letter to the other person.

WHAT YOU CAN DO • Chat by text — message your hatchling anytime in a private, familiar conversation. • Talk by voice — call it and just speak; it listens, thinks, and answers out loud. Every call is saved to its memory, so it remembers what matters to you. • Send a letter — decide what you want to get across; your hatchling writes it and delivers it to the other person. You bring the meaning; it finds the words. • Pick up where you left off — it remembers your conversations and calls, so nothing starts from scratch. • Stay organized — every hatchling in one simple list; see who's waiting to hear from you, accept or decline new requests.

A FEW RULES WE BUILT IN • One AI per relationship — no group chats, no crowd, no feed. • Nothing is hidden — you created it together, and it works for both of you. • Nothing sends itself — never automated, never broadcast. Every message is one you meant. • What your hatchling knows stays between the two of you. • Quiet by design — you're notified when a letter arrives for you, not pinged all day.

ALSO • No ads. Relay is free. • Fully bilingual — English and 中文. • Light and dark mode, on iPhone and iPad.
