🪙 Crypto charts · Astrologer
Every coin has a verifiable genesis moment. Cast natal charts, run transits against a coin,
or synastry a person with a market — desktop Astrologer parity, fully client-side.
Unlock with your Payhip Astrologer license key (same key as desktop).
Cast the chart type you want to hear about — genesis,
coin transits, or person ☍ coin — then hit
Interpret. Chart chat stays aware of whatever you cast this session.
Person ☍ coin needs your Chart-tab natal first.

Sonic prescription
Prescription is deterministic (no AI); optional AI lyric elaboration below is BYOK. Needs natal + a transit moment. If synastry Person B is cast, a light duet tint is added. Sound prompts favor one planetary lead color (less tag-soup).

Lyric scaffold
AI lyric elaboration (BYOK)
Expands the scaffold above into full lyrics using your BYOK provider — the seed phrase and remembrance prompt are transmuted into concrete images, never quoted verbatim.
Album art
A creative image prompt is generated alongside the lyrics — never deterministic. If your selected model/provider can generate images directly (e.g. Gemini 2.5 Flash Image, or an OpenRouter image model), one renders below too; otherwise paste the prompt into whatever image tool you like.
