Hi Product Hunt 👋

I'm Gabriel, the solo founder. Design, code and support are me. The models aren't: I use commercial LLMs. The work is the philosopher corpus, the prompting, the memory and the five languages.

Sagius started with my own hard days. I'm Brazilian. I built my life and my business from scratch in Germany, and on the difficult days I kept going back to the Stoics: Marcus Aurelius, Seneca, Epictetus.

Quote apps gave me one beautiful sentence and nothing more. I wanted the back-and-forth: what would Marcus Aurelius actually say about my problem, today?

So that's what Sagius is:

A daily quote, with a plain-language AI explanation of what it really means
1:1 chats with AI Socrates, Nietzsche, Marcus Aurelius and others: an interpretation of how they thought, not a quote database
Comfort sessions for hard days. Philosophy, not platitudes. It isn't therapy and doesn't pretend to be: in real distress it points you to someone you trust or a local crisis line
AI mentors you can hire for ongoing guidance (they remember your journey)
EN, FR, PT-BR, DE and ES from day one

Free to try: 10 AI credits when you open it, no account, no email. After that it's your choice: pay-as-you-go credits from EUR 1.99, or a plan if you use it daily (from EUR 4.99/month, or yearly). You are never forced into a subscription to keep using it.

Both iOS and Android are live today. Built solo, so tell me what's broken and I'll fix it this week.

Two small things: it's my birthday today, and this is my first Product Hunt launch. If I'm doing it wrong, say so and I'll get it right next time :)

Which philosopher would you want in your pocket on a bad day, and why?

Beautifully designed daily philosophy you can talk back to. Chats with Marcus, Nietzsche, Buddha and others in their own voice; clear quote explanations; Blend Two Minds; a comfort space for hard days. It turns reflection into a ritual instead of another feed.

Plain quote apps, ChatGPT roleplay, journals, and meditation apps. Those either stay on the surface or don’t feel like a real thinker. Sagius is the one that pairs a calm daily practice with a conversation grounded in actual ideas.
