Who each is for

Who Niyora and Replika are for

Niyora is for you if

The difference

What Niyora does that Replika doesn’t

Measured against what Replika describes on its own pages on 13 October 2026.

  • It knows your cycle

    Niyora predicts your PMS window from your own cycles, so Moon knows when a hard moment lands in it.

  • A start and an end

    Moon takes you from what happened to a decision: wait, or send a message you’ve drafted together.

  • Every idea shows its source

    Each perspective names where it comes from, such as CBT, Stoic philosophy or self-compassion research.

  • Private by design

    No account. Entries are encrypted on your phone, names and places are removed before the AI sees your text, and your text isn’t used to train the AI.
