Today, we are thrilled to officially announce the launch of Euthy AI—a suite of premium generative tools designed to elevate your personal reflection, storytelling, and journaling workflow. By integrating advanced natural language processing and image generation directly into Euthy Journal, we are opening new avenues for self-exploration and creative expression.
However, when designing Euthy AI, we asked ourselves a critical question: How do we leverage the power of cloud-hosted Large Language Models (LLMs) without compromising the strict local-first privacy that our users rely on? The result is a secure, sandboxed bridge between your local device and state-of-the-art AI endpoints hosted on the Google Cloud Platform (GCP).
Euthy Labs does not train models on your journal data. All AI operations are processed on dedicated enterprise GCP servers. Your prompts are not retained, cached, or used to train public models. Furthermore, your core journaling database remains 100% local-first and sandboxed on your physical device.
What is Euthy Premium AI?
Euthy Premium AI introduces a comprehensive suite of generative capabilities designed to act as an empathetic mirror to your mind, a visual companion, and an advanced archivist.
1. Chat with AI & Extended AI Companion Memory
Journaling is a conversation with yourself, but sometimes you need an empathetic listener. Euthy acts as a safe, private wellness companion. You can chat about your feelings, vent about a stressful day, or work through reflection exercises. With Extended AI Companion Memory enabled in settings, Euthy extends the active conversation history memory limit to the last 150 messages (up from the default 40), allowing for much longer, richer, and deeper conversations within your chat companion sessions.
2. Journal via AI & Automatic Entry Analysis
Do you ever stare at a blank page unsure of how to start? Journal via AI turns writing into a guided, structured conversation where Euthy interviews you about your day. Once complete, it compiles your thoughts into a formatted, first-person journal entry. Furthermore, the app features automatic entry analysis or summary, which automatically summarizes your logs, generates mood tags, and offers writing prompts in the background.
3. AI Semantic Memory Q&A & Semantic Journal Memory
Traditional keyword search fails when you can't remember the exact words you wrote. With AI Semantic Memory Q&A, you can query your past journal entries by context or meaning (e.g. "What has been making me happy lately?"). Using private text embeddings, Euthy parses the sentiment of your reflections to return immediate, secure answers.
Note: To enable semantic search, you can toggle the Semantic Journal Memory setting under Settings in the app to index your local entries.
4. AI Image Generation & AI Edit Image
Visualize the essence of your entries. Euthy AI integrates with Google Imagen for AI Image Generation, creating unique, high-fidelity artwork reflecting the mood of your writing. With AI Edit Image, you can use natural language instructions to modify, expand, or restyle your journal photos and drawings (e.g., "Add a warm sunset glow to this photo").
5. AI Wellness Insights (Monthly & Yearly)
Go beyond simple charts. Euthy generates advanced AI Wellness Insights during your monthly and yearly recaps, highlighting hidden trends in your mood distributions, life triggers, and physical health correlations to celebrate your personal growth over time.
How Euthy AI Protects Your Privacy
Unlike standard AI services that require accounts, centralized sync, and open data scraping, Euthy Journal runs on an isolated security model:
- Sandboxed Device Storage: Your entries and media are stored locally in the app's secure sandbox. They benefit from hardware-level encryption provided by your device's operating system, meaning your data is encrypted at rest whenever your device is locked.
- Share Health Data with AI Off by Default: Your physiological data (steps, heart rate, sleep) synced from Health Connect is strictly kept local-only and excluded from all AI prompts by default. You have complete control and must explicitly choose to toggle this feature ON under Settings.
- GCP Proxy: All requests to Gemini and Imagen go through Euthy's secure, anonymized Cloud Run proxy. The models never see your email, name, or metadata.
- Zero Retention: Google Cloud Platform enterprise API policies ensure that none of your processed data is stored on servers or used for model training.
