FateChart vs Astro-Seek: two free chart calculators, two very different scopes
Astro-Seek is the reference free Western calculator: every chart type, no paywall, ads everywhere. FateChart keeps the ‘free and open’ part and swaps breadth of Western sub-techniques for breadth of traditions — plus a modern mobile-first interface.
Pick Astro-Seek if you are a Western-astrology specialist who wants primary directions, fixed stars, horary and a 90,000-chart celebrity search. Pick FateChart if you want the same birth cast in Western, BaZi, Zi Wei and numerology without ads, a clean phone layout, Asian languages, and an optional AI reading you can buy for US$3.99.

Where Astro-Seek is strong
- Astonishing depth of free Western tools: primary directions, draconic, sidereal, Uranian dials, horary, electional, fixed stars, Arabic parts.
- A celebrity database of about 94,000 charts searchable by planet, house and aspect (site’s own count).
- No paid tier at all — its FAQ states there is currently no paid subscription; guest birth data is erased when you leave the page.
- Nine interface languages including Korean, Russian, Turkish and Portuguese.
Where FateChart is the better pick
Chinese astrology done properly, not a zodiac-animal lookup
Astro-Seek’s Chinese section is a 12-animal sign page. FateChart casts full BaZi pillars with day master, ten gods, five-element balance and ten-year luck pillars, plus Zi Wei Dou Shu with 12 palaces and 100+ stars.
No ads on the chart
Astro-Seek is funded by display ads and offers no way to remove them. FateChart’s free charts are ad-free; revenue comes from optional AI readings instead.
A built-in, labelled AI reading — not a copy-paste to ChatGPT
Astro-Seek’s ‘AI’ page formats your chart as text for you to paste into an external ChatGPT session. FateChart generates the reading in place from the full chart, labels it as AI, and charges US$3.99 for 10 credits.
Built for phones, and for Asia
FateChart is mobile-first and runs in Simplified and Traditional Chinese, Japanese, Vietnamese, Thai and Indonesian, which Astro-Seek does not offer.
Life K-Line and ranked compatibility
A free candlestick-style curve of ages 1–80 and a compatibility score that ranks up to five people — neither exists on Astro-Seek.
Report PDF and share link
One-click PDF and a read-only share link for any report; Astro-Seek does not state an equivalent.
Using FateChart alongside Astro-Seek
Keep Astro-Seek for specialist Western techniques — it is excellent at them. Use FateChart when you want the BaZi and Zi Wei view of the same birth, a clean chart on your phone, or a reading in an Asian language. The natal placements should agree; both default to Placidus and use the same time-zone data.
FateChart vs Astro-Seek: common questions
Is FateChart free like Astro-Seek?
Yes for the charts — Western, BaZi, Zi Wei Dou Shu and numerology are free without an account, and without ads. Only the optional AI interpretation costs credits (US$3.99 for 10).
Does FateChart have Astro-Seek’s advanced Western techniques?
No. FateChart covers the natal chart (planets, houses, aspects, big three) and synastry, not primary directions, horary or fixed stars. For those, Astro-Seek is the better tool.
Which has more celebrity charts?
Astro-Seek, by a wide margin (about 94,000). FateChart has hundreds, each shown in Western, BaZi and Zi Wei at once.
Does Astro-Seek do BaZi?
Only a Chinese zodiac animal lookup. It has no Four Pillars chart, day master, ten gods or luck pillars. FateChart casts all of these free.
How does the AI reading differ?
Astro-Seek prepares text for you to paste into ChatGPT yourself. FateChart generates the reading in place from the full chart data, marks it as AI-generated, and charges per reading.
