What if one question could change how you think?

Sygil doesn't just answer your question — it makes you think about it. Four perspectives. One deeper understanding.

Free with 5 questions/day. Premium from $3.75/mo billed yearly.

Every age. Every language. On device.

Translation happens entirely on device using Apple’s built-in Translation framework. Your words never leave your phone.
