Tideris (Eye of the Tide)

Tideris is a web toolkit for exploring traditional Chinese astrology. Its free BaZi option builds a Four Pillars chart from birth details and supplies a short AI-assisted interpretation. Free daily guidance and related cultural-content pages are available separately. These readings are entertainment and cultural material, not validated forecasts or professional advice.

Start with the free chart

The public form distinguishes a free quick reading from a paid detailed report. It asks for birth date and time and offers an optional birthplace-based solar-time correction. Unknown or inaccurate inputs can change the chart. The site describes chart calculation and AI interpretation as separate steps; a coherent explanation does not establish predictive accuracy.

Check which service a purchase covers

A membership does not unlock every reading. Current plans treat detailed BaZi interpretation, focus reports, I Ching/Liu Yao, Qi Men and compatibility as separate paid services. The basic chart and existing free daily content remain distinct from these purchases. Prices and entitlements differ between the international and Chinese sites.

Language and data considerations

The international service uses the Tideris name; the Chinese site is branded 潮汐之眼, or Eye of the Tide. They share the same toolkit and are covered here as language/regional versions of one product. The privacy policy says submitted birth information is sent to an AI service during interpretation and records may be stored in the cloud. The policy excludes under-18 users. Review it before entering another person's details. We inspected public forms and policies without submitting birth data or buying a reading.
