hi! i'm kate, your astrologer

Pencil sketch of Kate reading birth charts at her laptopfig. 02 — your astrologer

I've studied Tropical Western + Traditional/Hellenistic astrology for 4+ years, using astrology as a framework to help people understand themselves and the potential energies or patterns in their life better.

Although I follow modern interpretations of planets, rulers, and signs, I also bring in Traditional elements like decans and planetary dignities to gain deeper insight into placements. Most of my study has been in birth chart interpretations & understanding how astrology shows up in personal lives.

I use Placidus if you were born on/around the equator, and Whole Sign if you were born far north/south; if you have a house system preference, let me know!

  • Outside of astrology, I'm a creative developer in tech who's been making and managing websites for 3+ years.
  • I love exploring the intersection between spirituality, technology, and art, and I found that most birth chart generators weren't customisable enough for me. That's why I created my own webapp to fulfill my vision of an "ideal chart generator": something accurate (showing most major placements, aspects, and houses) as well as aesthetically customisable.

asked, answered

I don't know my birth time — can I still get a chart?

Yes. Use 12:00 noon as a stand-in so you can still generate a full chart. Your ascendant and house cusps may shift, so those parts become approximate. I can work around a missing time in a reading and focus on what remains reliable.

Placidus or whole sign — which should I pick?

Placidus tends to resonate better with those born near the equator, whereas Whole Sign works better with anyone born far north (e.g UK, Norway, Canada) or south (Chile, South Africa, Australia). If you already have a preference, that is always welcome.

What does my chart include?

You get your core placements, houses, and major aspects in one chart view. From there, you can tune colours, layout feel, and detail levels. It's built to be both accurate and customisable!

Is it really free? What's the catch?

Yes, the generator is free to use with no account and no email gate. There is no hidden paywall for basic chart creation. Readings and prints are optional, and they help fund the site :)

How do readings with Kate work?

Readings are available via Ko-fi as written interpretations. Start here: Book a reading ↗.

Can I print my chart?

Yes. The free download is a screen-grade PNG file, ideal for saving and sharing digitally. If you want a finished, high-quality piece for your wall, check out the birth chart prints in the shop: Browse poster prints ↗.
