What is Smart Reflection?

Writing is only half of the journaling journey. The other half is reflection. However, it can be difficult to see the "big picture" when you're caught in the day-to-day. Smart Reflections are intelligent, contextual insights that appear right on your Home View. They act as an AI companion that reads between the lines to show you how you're growing, what triggers your stress, and where you're finding joy.

💡
Pattern Detection: Smart Reflections don't just look at your last entry. They analyze up to 50 recent entries to find recurring themes that you might have missed.
🧠

How It Works: Semantic RAG

Smart Reflections are powered by a technology called Semantic RAG (Retrieval-Augmented Generation). Unlike standard search that looks for exact keywords, Eristotle understands the meaning behind your words.

Semantic Retrieval: When you open the app, Eristotle performs a semantic search across your journal for specific themes like "growth" or "relationships."
2
Local AI Analysis: The most relevant entries are analyzed by Eristotle's AI to identify connections and summarize the findings into a clear insight.
3
Evidence-Based: Every reflection includes "Related Entries" that you can expand to see exactly which parts of your journal informed the insight.

Privacy-First, Local Retrieval

Unlike traditional AI apps that index your private journal on their servers, Eristotle is built with a local-first philosophy. Your thoughts remain under your control.

  • On-Device Retrieval: All searching, indexing, and pattern detection happens entirely on your phone using on-device embeddings. Your full journal is never uploaded for training or analysis.
  • Your Choice of AI: Eristotle gives you total control over the AI provider. You can use on-device models like Apple Intelligence for complete privacy, or your own API keys for advanced analysis.
  • Zero Knowledge: We don't have a "master key" to your journal. Even when using an AI provider, only the specific context needed for your reflection is sent, and it's never stored by us.
