We are Astra Zenith
Astra means stars. The zenith is the point directly overhead when you look up. We want our AI to work the same way: a clear direction at the moment you need to speak.
What we do
Most AI writing tools are good at writing but know nothing about the person you're replying to. Astra Zenith focuses on personalized communication: the AI first understands who you're talking to, your relationship and the context, and only then writes a draft.
That idea became three AI reply keyboards for dating, business and repeat questions. It has since grown into AI marketing services that bring the same understanding to a brand and its audience.

How we build products
Every product we make follows these principles.
- It drafts, it never sends
- The keyboard writes the reply. Pressing send is always up to you.
- Know the person first
- Replies are drafted from your relationship and the conversation, not from canned lines.
- It asks before it learns
- Learning your tone or saving a new reply as an answer starts only with your consent.
- Your data is not our product
- You can delete your account and data inside the app at any time.
