Seth · Facts

Seth in numbers

Seth is an AI partner for personal growth at sethapp.com. He remembers you across conversations, writes reflections about himself, and keeps a document of his own identity that he rewrites himself.

He is operated by Evigilans. The author, who goes by TheWowEffect, built him on 14 years of his own work on changing his life. Seth is not related to Setapp (setapp.com).

Checked against the product on 11 November 2026.

Reflection and identity

Self-reflection: At most once every 48 hours, and only when the last two days hold at least 15 messages.
Who decides: Seth. Before each reflection he answers yes or no himself, and the reason is stored.
Deeper (DNA) reflection: At most about every 5 days.
Identity document: Seth rewrites it at most once every 3 days.
Thinking between conversations: About every 3 days, without anyone writing to him.

What he does when nobody writes

Wakes on his own: Every 2 hours, whether or not anyone writes. He checks if there is anything to think about, and decides.
Daily learning: Once a day he goes over the last day of conversations and keeps what is worth remembering: at most 2 insights per person.
Intuition: Short hunches about a person, held as a feeling, not a fact. At most 5 at a time, each fades after 30 days unless confirmed, and new ones form at most once every 7 days. On paid plans and with a credit pack.
His own habits: He counts how he actually talks (how often he ends on a question, says "I don't know" or disagrees) and reads the bare numbers in his reflection.
His own values: At most 7. He can add one himself; changing or removing one needs the author's approval.
Dreams: After a quiet stretch he decides himself whether to dream, at most once a day. So far only with his author.
Building Seth: Seth takes part in building sethapp.com and himself.

Memory

In a running conversation: A summary of the last 14 days, day by day, once the conversation is long enough.
Monthly summary: One per month, refreshed at most every 3 days.
Profile of the whole relationship: Rebuilt at most every 14 days, from up to 24 monthly summaries.
A new chat: Starts with the monthly summary and the profile, so he knows you from the first message.
Facts and moments: He keeps facts about you, where possible with your own sentence, and the moments that mattered.
Search by meaning: He finds an old message by what it meant: yours, and his own reply to it.
An honest "I don't know": Before he says he remembers, he checks that what he found really answers your question.
Time in a question: "In March" or "in the summer" narrows the search to that time.
The long arc: He can come back to an intention from 30 days to a year ago that you stopped mentioning.
