Spikka computes real natal charts first (ephemeris math), then uses AI only to explain them — so the sky is never invented by a language model. Free natal chart to start. Paid reports, synastry, forecasts and SpikkChat when you want depth. FR + EN.
Hey Product Hunt 👋 I’m François, maker of Spikka.
We built this because LLMs are great at language and terrible at astronomy — they invent planetary positions. Spikka calculates the chart deterministically, then uses AI only to narrate what’s actually there.
Happy to answer anything: accuracy, synastry, pricing, what’s free vs paid. What would you want to see first?
