Your chart deserves a conversation, not a caption.

Co–Star delivers polished daily snippets to your lock screen. Ask Kazmo picks up when you press a button and actually talks with you until things click.

See how it works

Co–Star turned astrology into a cultural moment, putting birth charts on millions of phones and making chart-comparing a social ritual. That is a real thing it did well. But a notification is not a conversation. When you want to understand why something in your chart keeps showing up in your life, you need to be able to ask follow-up questions out loud and get a warm, thoughtful answer back. That is the gap Ask Kazmo was built to fill.

	Ask Kazmo	Co–Star
How you interact	Real Conversation Press once and talk out loud. Kazmo listens, responds, and keeps going until you feel it.	One-Way Push Co–Star speaks through daily notifications and text cards. You read; you cannot talk back.
Daily experience	Sky Reading Each day opens with a spoken reading of your transits, delivered like a friend calling to walk you through your morning.	Daily Snippet A short, often cryptic text notification based on your Sun, Moon, and Rising signs arrives on your lock screen.
Learning your chart	Taught to You Ask anything about any placement in your natal chart and Kazmo explains it in plain language, at your pace.	Static Reference Your full chart is displayed, but there is no guide to teach you what the placements actually mean for your life.
Emotional tone	Warm and Grounded Kazmo is built to feel like a close, emotionally perceptive friend, never alarming, never cryptic.	Deliberately Blunt Co–Star leans into an ironic, sometimes unsettling voice that users describe as anxiety-inducing on hard days.
Planetary transits	Explained Live Kazmo walks you through what is moving in your sky right now and what it tends to feel like in real life.	Brief Labels Transit names appear in the app but without the plain-language explanation of what they mean for you personally.
Social and sharing	Private by Design No social feed, no public profile, no comparing scores. Your conversations are yours to keep or delete.	Built for Sharing Friend chart comparisons and compatibility scores are Co–Star's most-loved feature and its core social hook.
Depth of personalization	Full Chart Fluency Every house, aspect, and transit in your chart is fair game for a real back-and-forth conversation.	Sign-Level Focus Daily readings center on Sun, Moon, and Rising, leaving most of your chart's nuance untouched.
Voice and audio	Spoken Out Loud The whole experience is voice-first. Kazmo speaks to you and listens when you speak back.	Text Only Co–Star is entirely text and visual. There is no voice, no audio, and nothing that talks back.

What it feels like to actually use each one

Opening Co–Star is like checking a very stylish horoscope column: you get a crisp, sometimes poetic line about your day, and then you close the app. Opening Ask Kazmo is more like calling a friend who knows your chart cold. You say what is on your mind, they respond with something that actually connects to your placements, and the conversation finds its own rhythm. One experience is fast and decorative. The other is the one you remember.

Why voice changes what astrology can do for you

There is a specific kind of understanding that only comes from hearing something explained out loud and being able to say, "wait, what does that mean for me?" Reading a notification does not get you there. Talking through your Saturn placement, or your current Venus transit, or why a certain pattern keeps repeating in relationships, requires a real exchange. Ask Kazmo was built around that exchange, which is why it can meet you where you actually are on a given day rather than where an algorithm predicted you would be.

Co–Star made astrology social. Kazmo makes it personal.

Co–Star deserves real credit for making chart-sharing a mainstream social ritual and for bringing millions of people into astrology who never would have found it otherwise. But the social layer is also what defines its ceiling: the experience is shaped around what you can show a friend, not what you can learn alone in a quiet moment. Ask Kazmo has no feed, no comparison scores, and no public profile, because the deepest conversations about your chart are private ones.

A voice journal your chart can actually read

Ask Kazmo includes a private voice journal with transcripts, so the things you work through in conversation do not disappear. Over time you build a record of what you noticed, what shifted, and what the sky looked like when it happened. Co–Star stores your chart data but not your reflections. The difference is the difference between a mirror and a diary.

Co–Star is a genuinely good entry point to astrology and still the best app in the world for comparing charts with friends. If that social ritual is what you are looking for, it does the job beautifully. But if you want to actually understand your chart, work through a question out loud, and feel like something heard you, Ask Kazmo is the conversation Co–Star was never designed to have.

Frequently asked questions

Can I use Ask Kazmo if I already know my chart from Co–Star?

Absolutely. Most people come to Kazmo already knowing their Sun, Moon, and Rising from Co–Star or somewhere else. Kazmo picks up from there and goes much deeper: the houses, the aspects, the transits that are moving right now and what they tend to stir up. Knowing your basics just means the conversation starts further along.

Why does Ask Kazmo use voice instead of text?

Because the questions that matter most about your chart are not search queries. They are things you half-know how to say, things you are still figuring out as you talk. A voice conversation lets you think out loud, get a real response, and follow up in the same breath. Text-based apps answer the question you typed. Kazmo answers the question you were actually trying to ask.

Is Ask Kazmo private? Co–Star has a social feed and I am not sure I want that.

Ask Kazmo has no social feed, no public profiles, and no chart comparison scores. Your conversations are private and deletable. The whole experience is designed for the kind of honest, inward reflection that works better without an audience.

How do I get started with Ask Kazmo?

Download the app on the App Store or Google Play and start a free trial inside the app. You will enter your birth details, and then you can press the button and start your first real conversation with your chart. No reading required, no setup quiz. Just talk.
