The star feature

An AI receptionist that actually answers.

Voicemail loses you leads. Phone trees annoy your callers. Redtie has a real conversation — it greets the caller, understands what they need, answers simple questions, and takes a message you’ll actually want to read.

Don’t take our word for it — call (408) 583-6325

Natural conversation

Multi-turn, real-time, interruptible (barge-in) — never a robot reading at you.

Messages worth reading

Who called, why, and what they need — summarized for you.

You decide when it answers

Always, after no answer, or off. It won’t hand out your private details.
